UINavigationBar
XIBなしで2つのボタンを追加するにはどうすればよいですか?
2つのボタンはの右側に配置する必要がありUINavigationBar
ます。
ボタンを1つ追加する方法は知っていますが、2つ追加する方法はありますか?
回答:
iOS 5以降では、次のように簡単です。
UIBarButtonItem *btnShare = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(share)];
UIBarButtonItem *btnRefresh = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh)];
[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:btnShare, btnRefresh, nil]];
ナビゲーションバーの右側に2つのボタンを追加するコード(以下を参照)を投稿しました。barStyle = -1
サブクラス化の代わりに設定できUIToolbar
ます。
UIToolbar *tools = [[UIToolbar alloc]
initWithFrame:CGRectMake(0.0f, 0.0f, 103.0f, 44.01f)]; // 44.01 shifts it up 1px for some reason
tools.clearsContextBeforeDrawing = NO;
tools.clipsToBounds = NO;
tools.tintColor = [UIColor colorWithWhite:0.305f alpha:0.0f]; // closest I could get by eye to black, translucent style.
// anyone know how to get it perfect?
tools.barStyle = -1; // clear background
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3];
// Create a standard refresh button.
UIBarButtonItem *bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh:)];
[buttons addObject:bi];
[bi release];
// Create a spacer.
bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
bi.width = 12.0f;
[buttons addObject:bi];
[bi release];
// Add profile button.
bi = [[UIBarButtonItem alloc] initWithTitle:@"Profile" style:UIBarButtonItemStylePlain target:self action:@selector(goToProfile)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// Add buttons to toolbar and toolbar to nav bar.
[tools setItems:buttons animated:NO];
[buttons release];
UIBarButtonItem *twoButtons = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
self.navigationItem.rightBarButtonItem = twoButtons;
[twoButtons release];
tools.barStyle = -1
行です。これがないと、UIBarStyleBlackをtranslucent = YESで使用すると、視覚的なアーティファクトが発生します。(つまり、背景色がナビゲーションバーの色と一致しません。)それは文書化されていない機能ですか?もしそうなら、このコードはちょっと壊れやすいです。ドキュメントのどこにもそれを見たことがありません。
ツールバーで初期化されたバーボタンをカスタムビューとして使用できます。
UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 103.0f, 44.01f)];
NSArray* buttons = [NSArray arrayWithObjects:self.editButtonItem, someOtherButton, nil];
[toolbar setItems:buttons animated:NO];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar];
このようなものを与えるだろう:
注:この回答はiOS6以降では廃止されています
これが私の現在のプロジェクトからの実際の例です:
UIButton *homeBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[homeBtn setImage:[UIImage imageNamed:@"home-icon"] forState:UIControlStateNormal];
//[homeBtn addTarget:self action:@selector(home) forControlEvents:UIControlEventTouchUpInside];
[homeBtn setFrame:CGRectMake(0, 0, 32, 32)];
UIButton *settingsBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[settingsBtn setImage:[UIImage imageNamed:@"settings-icon"] forState:UIControlStateNormal];
//[settingsBtn addTarget:self action:@selector(settings) forControlEvents:UIControlEventTouchUpInside];
[settingsBtn setFrame:CGRectMake(44, 0, 32, 32)];
UIView *rightBarButtonItems = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 76, 32)];
[rightBarButtonItems addSubview:homeBtn];
[rightBarButtonItems addSubview:settingsBtn];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarButtonItems];
UINavigationBar *navBarView = [[UINavigationBar alloc] initWithFrame: CGRectMake(0.0f, 0.0f, 320.0f, 42.0f)];
navBarView.tintColor= [UIColor colorWithRed:90.0/255.0f green:53.0/255.0f blue:45.0/255.0f alpha:1.0];
UIBarButtonItem *left=[[UIBarButtonItem alloc]initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:@selector(backView)];
UIBarButtonItem *right=[[UIBarButtonItem alloc]initWithTitle:@"Save" style:UIBarButtonItemStylePlain target:self action:@selector(SaveImage)];
UIBarButtonItem *Add=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(AddComment:)];
UINavigationItem *navigationItem = [[UINavigationItem alloc] init];
navigationItem.leftBarButtonItem = left;
NSMutableArray *buttonArray=[[NSMutableArray alloc]initWithCapacity:2];
[buttonArray addObject:right];
[buttonArray addObject:Add];
navigationItem.rightBarButtonItems = buttonArray;
[navBarView pushNavigationItem:navigationItem animated:NO];
[self.view addSubView:navBarView];
迅速:
override func viewDidLoad() {
super.viewDidLoad()
// Additional bar button items
let button1 = UIBarButtonItem(image: UIImage(named: "image1.png"), style: .Plain, target: self, action: "methodA")
let button2 = UIBarButtonItem(image: UIImage(named: "image2.png"), style: .Plain, target: self, action: "methodB")
let button3 = UIBarButtonItem(image: UIImage(named: "image3.png"), style: .Plain, target: self, action: "methodC")
navigationItem.leftItemsSupplementBackButton = true
navigationItem.setLeftBarButtonItem(button1, animated: true)
navigationItem.setRightBarButtonItems([button2, button3], animated: true)
ボタンの方法:
func methodA() {
performSegueWithIdentifier("segA", sender: nil)
}
func methodB() {
performSegueWithIdentifier("segB", sender: nil)
}
func methodC() {
performSegueWithIdentifier("segC", sender: nil)
}
あなたはこのように迅速に行うことができます
var editImg : UIImage = UIImage(named: "plus")!
var searchImg : UIImage = UIImage(named: "search")!
var editBtn : UIBarButtonItem = UIBarButtonItem(image: editImg, style: UIBarButtonItemStyle.Plain, target: self, action: Selector("editBtnPressed:"))
var searchBtn : UIBarButtonItem = UIBarButtonItem(image: searchImg, style: UIBarButtonItemStyle.Plain, target: self, action: Selector ("searchBtnPressed:"))
var buttons : NSArray = [editBtn, searchBtn]
self.navigationItem.rightBarButtonItems = buttons
func editBtnPressed(sender: AnyObject){
}
func searchBtnPressed(sender: AnyObject){
}
UIViewを作成し、そのビューに2つのボタンを追加できます。そして、そのUIViewを右ボタンとして追加します:)
UIView* rightItem = [UIView alloc] initWithFrame:frame];
//Create UIButton1 b1
//Create UIButton2 b2
[rightItem addSubview:b1];
[rightItem addSubview:b2];
self.navigationItem.rightBarButtonItem = rightItem;
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView: rightItem];
(以下の完全に機能するコードサンプル[私による])
Prakashの応答はInterfaceBuilderでも機能します。
にをドラッグするUIView
と、UINavigationItem
いくつかUIButton
をこの子として配置し、次のUIView
ような階層を作成できます。
の背景色UIView
をクリアに設定し、いくつかの制約を追加してボタンを垂直方向に中央揃えにし、水平方向の位置を固定します。これが私がゼロ行のコードで得た結果です:
SWIFTでは、次のコードを追加して、右側(または左側)に2つのボタンを設定できます。
self.navigationItem.rightBarButtonItems = [UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Action, target: self, action: "barButtonItemClicked"), UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Search, target: self, action: "barButtonItemClicked")]
iOS 5以降、簡単に実現できます。UINavigationItemには、バーの左側と右側に複数のボタンを配置する機能があります。
Swift4のコードは次のとおりです。
let editImage = UIImage(named: "plus")!
let searchImage = UIImage(named: "search")!
let editButton = UIBarButtonItem(image: editImage, style: .plain, target: self, action:#selector(didTapEditButton))
let searchButton = UIBarButtonItem(image: searchImage, style: .plain, target: self, action:#selector(didTapSearchButton))
navigationItem.rightBarButtonItems = [editButton, searchButton]
@objc func didTapEditButton(sender: AnyObject){
}
@objc func didTapSearchButton(sender: AnyObject){
}
2つのボタンを追加する必要はありません。追加する必要があります
UIBarButtonSystemItemFlexibleSpace
ない
UIBarButtonSystemItemFixedSpace
右側にボタンがあります。
このような:
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
toolbar.barStyle = UIBarStyleBlackTranslucent;
UIBarButtonItem *spaceButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *infoButtonItem1 = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(empresaTextFieldDone)];
toolbar.items = [NSArray arrayWithObjects: spaceButton, infoButtonItem1, nil];
UIView* buttonsView= [[UIView alloc] initWithFrame:CGRectMake(10, 6, 84, 32)];
buttonsView.backgroundColor=[UIColor clearColor];
btn_back = [UIButton buttonWithType:UIButtonTypeCustom];
[btn_back addTarget:self action:@selector(backButtonClick)
forControlEvents:UIControlEventTouchUpInside];
btn_back.frame = CGRectMake(0, 0, 32, 32);
btn_back.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"close.png"]];
btn_help = [UIButton buttonWithType:UIButtonTypeCustom];
[btn_help addTarget:self action:@selector(helpButtonClick)
forControlEvents:UIControlEventTouchUpInside];
btn_help.frame = CGRectMake(42, 0, 32, 32);
btn_help.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"info.png"]];
[buttonsView addSubview:btn_back];
[buttonsView addSubview:btn_help];
segmentItem = [[UIBarButtonItem alloc] initWithCustomView:buttonsView];
self.navigationItem.rightBarButtonItem = segmentItem;
SWIFTの場合:
(あなたがナビゲーションコントローラーを持っていると仮定します)ルートコントローラーでこのコードを使用します:
左:..
let leftBtn = UIBarButtonItem(title: "Do It", style: UIBarButtonItemStyle.Plain,
target: self, action: "doIt:")
leftBtn.tag=100
self.navigationItem.leftBarButtonItem = leftBtn
正しい:
let rightView = UIView(frame: CGRectMake(0, 0, 100, 30))
rightView.backgroundColor = UIColor.redColor()
let btn1 = UIButton(frame: CGRectMake(0,0,60, 20))
btn1.setTitle("R1", forState: UIControlState.Normal)
btn1.tag=101
btn1.addTarget(self, action: "doIt:", forControlEvents: UIControlEvents.TouchUpInside)
rightView.addSubview(btn1)
let btn2 = UIButton(frame: CGRectMake(30,0,60, 20))
btn2.setTitle("R2", forState: UIControlState.Normal)
btn2.tag=102
btn2.addTarget(self, action: "doIt:", forControlEvents: UIControlEvents.TouchUpInside)
rightView.addSubview(btn2)
let rightBtn = UIBarButtonItem(customView: rightView)
self.navigationItem.rightBarButtonItem = rightBtn;
..
どこ:
func doIt(sender: AnyObject!){
let tag = sender.tag
}
func makeCustomNavigationBar () {
// Create the navigation bar
let navigationBar = UINavigationBar(frame: CGRectMake(0, 20, self.view.frame.size.width, 44)) // Offset by 20 pixels vertically to take the status bar into account
navigationBar.backgroundColor = UIColor.init(hexString: "E43037")
navigationBar.delegate = self;
navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
navigationBar.shadowImage = UIImage()
navigationBar.translucent = true
// Create a navigation item with a title
let navigationItem = UINavigationItem()
navigationBar.tintColor = UIColor.whiteColor()
navigationItem.title = "Forgot Password"
navigationBar.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]
// Create left and right button for navigation item
let leftButton = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
leftButton.action = "returnToLoginView"
let backbuttonImageView = UIImageView(frame: CGRectMake(0, 0, 30, 30))
backbuttonImageView.image = UIImage(named: "nav-arrow-left")
leftButton.image = backbuttonImageView.image
navigationItem.leftBarButtonItem = leftButton
let rightButton = UIBarButtonItem(title: "Right", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
rightButton.action = "navigateToDashBoardView"
let rightButtonImageView = UIImageView(frame: CGRectMake(0, 0, 30, 30))
rightButtonImageView.image = UIImage(named: "nav-arrow-left")
rightButton.image = backbuttonImageView.image
navigationItem.rightBarButtonItem = rightButton
// Assign the navigation item to the navigation bar
navigationBar.items = [navigationItem]
// Make the navigation bar a subview of the current view controller
self.view.addSubview(navigationBar)
}
