ユーザーがSwiftで画像を選択できるようにするにはどうすればよいですか?


89

私はSwiftで最初のiOSアプリケーション(iPhoneのみ)を書いています。メインアプリケーションビューでは、ユーザーがフォトギャラリーから画像を選択できるようにする必要があります。

ViewController.swiftの次のサンプルコードを見つけました:

class ViewController: UIImagePickerController, UINavigationControllerDelegate, UIImagePickerControllerDelegate  {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {

        var imagePickerController = UIImagePickerController()
        imagePickerController.delegate = self
        imagePickerController.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
        imagePickerController.allowsEditing = true
        self.presentViewController(imagePickerController, animated: true, completion: { imageP in

        })
    }


    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {
        let selectedImage : UIImage = image
        println(selectedImage)
    }

}

次のViewControllerシーンがあります-

View Controller
 - Top Layout Guide
 - Bottom Layout Guide
 - View
   - Image View

しかし、アプリを起動すると、黒い画面だけが表示されます。私が間違っていることは何ですか?私が見つけた別のサンプルコードはObjective-Cにありますが、これは役に立ちません。


1つの問題は、didSselectRowAtIndePathがUITableViewDelegateのデリゲート呼び出しである可能性があります。シーンのレイアウトとコードによると、ここで使用されているテーブルビューはなく、ViewControllerはUITableViewDelegateではありません。たぶん、開始すると、機能する空白のプロジェクトが機能し、ボタンが追加され、ボタンを押すだけでコードが起動されます。

UIImagePickerControllerを使用してユーザーに画像を選択させる場合は、次のコードを使用します。

import UIKit


class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    @IBOutlet var chooseBuuton: UIButton!
    var imagePicker = UIImagePickerController()

    @IBAction func btnClicked() {

        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
        self.dismiss(animated: true, completion: { () -> Void in

        })

        imageView.image = image
    }
}

ユーザーにボタンを押して画像を選択させたくない場合はどうすればよいですか?

funcから@IBactionを削除し、viewDidLoadで言いたいとき、または単に呼び出したいときはいつでもfuncを呼び出します

ありがとう。それは言うAttempt to present <UIImagePickerController: 0x7fdb84029800> on <MyApp.ViewController: 0x7fdb838360a0> whose view is not in the window hierarchy!。シーンに何かを追加する必要がありますか?

私はbcに賛成しました。これは本当に役に立ちました。NSDictionaryを[NSObject:AnyObject]に変更するだけで、うまく機能します。

import Foundation
import UIKit


class ImagePickerManager: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    var picker = UIImagePickerController();
    var alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
    var viewController: UIViewController?
    var pickImageCallback : ((UIImage) -> ())?;
    
    override init(){
        super.init()
        let cameraAction = UIAlertAction(title: "Camera", style: .default){
            UIAlertAction in

        }
        let galleryAction = UIAlertAction(title: "Gallery", style: .default){
            UIAlertAction in

        }
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel){

    func pickImage(_ viewController: UIViewController, _ callback: @escaping ((UIImage) -> ())) {
        pickImageCallback = callback;
        self.viewController = viewController;

        alert.popoverPresentationController?.sourceView = self.viewController!.view

        viewController.present(alert, animated: true, completion: nil)
    }
    func openCamera(){
        alert.dismiss(animated: true, completion: nil)

            picker.sourceType = .camera
            self.viewController!.present(picker, animated: true, completion: nil)
        } else {
            let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
            alertWarning.show()
        }
    }
    func openGallery(){
        alert.dismiss(animated: true, completion: nil)
        picker.sourceType = .photoLibrary
        self.viewController!.present(picker, animated: true, completion: nil)
    }

    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }
    //for swift below 4.2
    //func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    //    picker.dismiss(animated: true, completion: nil)

        guard let image = info[.originalImage] as? UIImage else {
            fatalError("Expected a dictionary containing an image, but was provided the following: \(info)")
        }
        pickImageCallback?(image)
    }



    @objc func imagePickerController(_ picker: UIImagePickerController, pickedImage: UIImage?) {
    }

}

次のように、ビューコントローラから呼び出します。

    ImagePickerManager().pickImage(self){ image in
        //here is the image
    }

また、次のキーを含めることを忘れないでくださいinfo.plist

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

この問題を修正するために、次のコードを追加しました。ifalert.actions.count> 0 {// self.present(alert、animated:true、completion:nil)をキャンセルした後にアラートが再度呼び出されました} else {alert.addAction(cameraAction)alert .addAction(galleryAction)alert.addAction(cancelAction)self.present(アラート、アニメーション:真、終了:ゼロ)}

@ Ing.Ron addActionsは一度だけ設定する必要があるため、代わりにinitメソッドに配置する必要があります-コードを更新しました。問題が発生した場合は
お知らせください

@vir us:迅速な対応に感謝します!私の場合、あなたのinit()コードをviewDidLoad()に入れました。これは私にとっては問題なく機能します!
のIng。ロン

Swift 3の場合:

  1. まず、info.plistに次のキーを追加する必要があります。

        <key>NSPhotoLibraryUsageDescription</key>
    <string>This app requires access to the photo library.</string>
    
  2. Viewコントローラは、次のプロトコルに準拠する必要があります。 UIImagePickerControllerDelegateUINavigationControllerDelegate

    class ImagePickerViewController:  UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate {}
    
  3. 返された/選択された画像をバインドするために使用するUIImageを宣言する必要があります。

    @IBOutlet weak var myImageView: UIImageView!
    @IBoutlet weak var upLoadImageBtn:UIImage!
    let imagePicker = UIImagePickerController()
    
  4. pickerImageデリゲートをViewControllerに設定します。

    imagePicker.delegate = self
    
  5. アップロードボタンの場合、アクションを実行して画像ピッカーを表示するには、次の画像にリンクする必要があります。

    @IBAction func upLoadImageBtnPressed(_ sender: AnyObject) {
        imagePicker.allowsEditing = false
        imagePicker.sourceType = .photoLibrary
    
    
        /*
        The sourceType property wants a value of the enum named        UIImagePickerControllerSourceType, which gives 3 options:
    
        UIImagePickerControllerSourceType.PhotoLibrary
        UIImagePickerControllerSourceType.Camera
        UIImagePickerControllerSourceType.SavedPhotosAlbum
    
        */
        present(imagePicker, animated: true, completion: nil)
    
    }
    
  6. Viewコントローラーは、イメージピッカーデリゲートのデリゲートメソッドを実装する必要があります。

    // MARK: - ImagePicker Delegate
    
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    
        if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
            myImageView.contentMode = .scaleAspectFit
            myImageView.image = pickedImage
        }
    
    
        /*
    
        Swift Dictionary named “info”.  
        We have to unpack it from there with a key asking for what media information we want.
        We just want the image, so that is what we ask for.  For reference, the available options are:
    
        UIImagePickerControllerMediaType
        UIImagePickerControllerOriginalImage
        UIImagePickerControllerEditedImage
        UIImagePickerControllerCropRect
        UIImagePickerControllerMediaURL
        UIImagePickerControllerReferenceURL
        UIImagePickerControllerMediaMetadata
    
        */
        dismiss(animated: true, completion: nil)
    }
    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        dismiss(animated: true, completion:nil)
    }

私はあなたに画像を選ぶための最も理解しやすいコーディングを与えます、これを参照してください

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) 
{
     var alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
     var cameraAction = UIAlertAction(title: "Camera", style: UIAlertActionStyle.Default)
     {
        UIAlertAction in
        self.openCamera()
     }
     var gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertActionStyle.Default)
     {
        UIAlertAction in
        self.openGallary()
     }
     var cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel)
     {
        UIAlertAction in
     }

    // Add the actions
     picker?.delegate = self
     alert.addAction(cameraAction)
     alert.addAction(gallaryAction)
     alert.addAction(cancelAction)
     self.presentViewController(alert, animated: true, completion: nil)
}
func openCamera()
{
    if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera))
    {
        picker!.sourceType = UIImagePickerControllerSourceType.Camera
        self .presentViewController(picker!, animated: true, completion: nil)
    }
    else
    {
        let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
        alertWarning.show()
    }
}
func openGallary()
{
    picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(picker!, animated: true, completion: nil)
}

//PickerView Delegate Methods
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])
{
    picker .dismissViewControllerAnimated(true, completion: nil)
    imageView.image=info[UIImagePickerControllerOriginalImage] as? UIImage
}
func imagePickerControllerDidCancel(picker: UIImagePickerController)
{
    println("picker cancel.")
}

ごきげんよう:-)

Swift 5では、これを行う必要があります

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    var imagePicker = UIImagePickerController()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func setPicture(_ sender: Any) {
        if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
            imagePicker.delegate = self
            imagePicker.sourceType = .photoLibrary
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        picker.dismiss(animated: true, completion: nil)
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            imageView.image = image
        }

    }

フォトライブラリ画像をすばやくコーディングして表示するには、次のようにします。

var pkcrviewUI = UIImagePickerController()
        if UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary)
        {
            pkcrviewUI.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
            pkcrviewUI.allowsEditing = true
            pkcrviewUI.delegate = self
            [self .presentViewController(pkcrviewUI, animated: true , completion: nil)]
        }

私はこれが1年前の質問であることを知っていますが、これは私にとってうまく機能している非常に単純なコード(主にこのチュートリアルからのもの)です:

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var imageView: UIImageView!

var imagePicker = UIImagePickerController()

override func viewDidLoad() {
    super.viewDidLoad()

    self.imagePicker.delegate = self
}

@IBAction func loadImageButtonTapped(sender: AnyObject) {
    print("hey!")
    self.imagePicker.allowsEditing = false
    self.imagePicker.sourceType = .SavedPhotosAlbum

    self.presentViewController(imagePicker, animated: true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        self.imageView.contentMode = .ScaleAspectFit
        self.imageView.image = pickedImage
    }

    dismissViewControllerAnimated(true, completion: nil)

}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    self.imagePicker = UIImagePickerController()
    dismissViewControllerAnimated(true, completion: nil)
}

Swift4の場合
このコードは私のために働いています!!

    var imagePicker = UIImagePickerController()

    override func viewDidLoad() {

        imagePicker.delegate = self
    }
    @IBAction func btnClicked() {

    if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum) 
    {
        print("Button capture")
        imagePicker.sourceType = .savedPhotosAlbum;
        imagePicker.allowsEditing = false

        self.present(imagePicker, animated: true, completion: nil)
        }
    }

  @objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

もちろん、上記の答えは主な問題を解決します。

Info.plistに次のフラグがなかったため、フォトアルバムの起動中にSwift3.0でクラッシュが発生しました。

  1. プライバシー-フォトライブラリの使用法の説明-> NSPhotoLibraryUsageDescription

  2. プライバシー-カメラの使用法の説明-> NSCameraUsageDescription

[スクリーンショット[1]

同様の問題が発生した場合は、それらを追加してください。

ありがとう!

これを行う簡単な方法は次のとおりです。

ただし、最初にinfo.plistに(プライバシー-フォトライブラリの使用法の説明)を追加する必要があり、viewControllerにボタンとUIImageViewが必要です。

次に、UIImageViewのアウトレット(このコードではアウトレットはmyImageと呼ばれます)とボタンのアクション(コードでインポートするアクションと呼びます)を作成します。

import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

    }
    @IBOutlet weak var myImage: UIImageView!
    @IBAction func importing(_ sender: Any) {
        let Picker = UIImagePickerController()
        Picker.delegate = self
        Picker.sourceType = .photoLibrary
        self.present(Picker, animated: true, completion: nil)
        Picker.allowsEditing = true
        Picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
    }

     func imagePickerController(_ picker: UIImagePickerController,didFinishPickingMediaWithInfo info: [String : Any])
    {
        let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage //1
        myImage.contentMode = .scaleAspectFit //2
        myImage.image = chosenImage //3
        dismiss(animated:true, completion: nil) //4
    }

}

別のボタンが必要ない場合は、別の方法があります。imageView自体にジェスチャーを添付しました。画像をタップすると、2つのオプションでアラートがポップアップ表示されます。ギャラリー/フォトライブラリから選択するか、アラートをキャンセルするかを選択できます。

import UIKit
import CoreData

class AddDetailsViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var imageView: UIImageView!

var picker:UIImagePickerController? = UIImagePickerController()

@IBAction func saveButton(sender: AnyObject) {
    let managedContext = (UIApplication.sharedApplication().delegate as? AppDelegate)!.managedObjectContext

    let entity = NSEntityDescription.entityForName("Person", inManagedObjectContext: managedContext)

    let person = Person(entity: entity!, insertIntoManagedObjectContext: managedContext)

    person.image = UIImageJPEGRepresentation(imageView.image!, 1.0) //imageView.image

ボタンをクリックして画像ギャラリーを開き、imageview swift3.0で画像を設定します

3つのデリゲートUIImagePickerControllerDelegate、UIPopoverControllerDelegate、UINavigationControllerDelegateを追加します

    picker!.sourceType = UIImagePickerControllerSourceType.photoLibrary
    present(picker!, animated: true, completion: nil)
}

ここで答えるだけでinfo[UIImagePickerControllerEditedImage]、おそらくほとんどの場合に使用したいものです。

それ以外は、ここでの答えは包括的です。

これを試してみてください。簡単です。UIImagePickerControllerDelegateを使用して画像をPicする

    @objc func masterAction(_ sender: UIButton)
    {
        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum;
            imagePicker.allowsEditing = false

            self.present(imagePicker, animated: true, completion: nil)
        }

        print("hello i'm touch \(sender.tag)")
    }

    func imagePickerControllerDidCancel(_ picker:
        UIImagePickerController) {
        dismiss(animated: true, completion: nil)
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
            print("Get Image \(chosenImage)")
            ImageList.insert(chosenImage, at: 0)
            ArrayList.insert("", at: 0)
            Collection_Vw.reloadData()
        } else{
            print("Something went wrong")
        }

        self.dismiss(animated: true, completion: nil)
    }

以下のコードを使用して通常の画像のみを選択する場合は、選択した画像がパノラマ画像ではないことを確認してください。

let picker = UIImagePickerController()

func photoFromLibrary() {

        self.picker.allowsEditing = true
        self.picker.sourceType = .photoLibrary
        //picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!

        self.present(self.picker, animated: true, completion: nil)

}

func shootPhoto() {

            if UIImagePickerController.isSourceTypeAvailable(.camera) {
                self.picker.allowsEditing = true
                self.picker.sourceType = UIImagePickerControllerSourceType.camera
                self.picker.cameraCaptureMode = .photo
                self.picker.modalPresentationStyle = .fullScreen
                self.present(self.picker,animated: true,completion: nil)
            }

}

//Image picker delegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    let str = "\(info["UIImagePickerControllerOriginalImage"]!)"

    let s = str.slice(from: "{", to: "}")

    if let arr = s?.components(separatedBy: ","){
        if arr.count >= 2 {
            if Int(arr[0])! > 11000 {
                picker.dismiss(animated:true, completion: nil)
                self.makeToast("Invalid Image!!!")
                return
            }
                     }
        }
    }

    if  let image = info[UIImagePickerControllerOriginalImage] as? UIImage{
        self.UserImageView.image = image
    }
    picker.dismiss(animated:true, completion: nil)
}

Xcode 10、Swift 4.2

以下は、実装のわずかに最適化されたバージョンです。これはSwift4.2にあり、私もテストしました。

ViewControllerの完全なコードはここで確認できます。ストーリーボードでも定義および接続されたIBOutlet(imageView)およびIBAction(didTapOnChooseImageButton)を定義する必要があることに注意してください。お役に立てれば。

import UIKit

class ImagePickViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate {

var imagePicker = UIImagePickerController()
@IBOutlet weak var imageView: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
}

@IBAction func didTapOnChooseImageButton(_ sender: Any) {
    let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertController.Style.actionSheet)
    let cameraAction = UIAlertAction(title: "Camera", style: UIAlertAction.Style.default) {
        UIAlertAction in
        self.openCamera(UIImagePickerController.SourceType.camera)
    }
    let gallaryAction = UIAlertAction(title: "Gallary", style: UIAlertAction.Style.default) {
        UIAlertAction in
        self.openCamera(UIImagePickerController.SourceType.photoLibrary)
    }
    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel) {
        UIAlertAction in
    }

    // Add the actions
    imagePicker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate
    alert.addAction(cameraAction)
    alert.addAction(gallaryAction)
    alert.addAction(cancelAction)
    self.present(alert, animated: true, completion: nil)
}

func openCamera(_ sourceType: UIImagePickerController.SourceType) {
    imagePicker.sourceType = sourceType
    self.present(imagePicker, animated: true, completion: nil)
}

//MARK:UIImagePickerControllerDelegate

func imagePickerController(_ picker: UIImagePickerController,
                                    didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    imageView.image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
    imagePicker.dismiss(animated: true, completion: nil)
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    print("imagePickerController cancel")
}

}

あなたはここのようにすることができます

var avatarImageView = UIImageView()
var imagePicker = UIImagePickerController()
        
func takePhotoFromGallery() {
    imagePicker.delegate = self
    imagePicker.sourceType = .savedPhotosAlbum
    imagePicker.allowsEditing = true
    
    present(imagePicker, animated: true)
}

func imagePickerController(_ picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let pickedImage = info[.originalImage] as? UIImage {
        avatarImageView.contentMode = .scaleAspectFill
        avatarImageView.image = pickedImage
    }
    self.dismiss(animated: true)
}

これがお役に立てば幸いです
