Modelクラスを使用してtableViewとcollectionViewのセルを管理する非常に簡単な方法を見つけました。
確かに、これを処理するより良い方法があります。これは、セルと値の管理に役立ちます。
これが私の出力（スクリーンショット）ですので、これを見てください：
- モデルクラスの作成は非常に簡単です。以下の手順に従ってください。name
RNCheckedModelでswiftクラスを作成し、以下のようにコードを記述します。
class RNCheckedModel: NSObject {
var is_check = false
var user_name = ""
}
- セルクラスを作成する
class InviteCell: UITableViewCell {
@IBOutlet var imgProfileImage: UIImageView!
@IBOutlet var btnCheck: UIButton!
@IBOutlet var lblName: UILabel!
@IBOutlet var lblEmail: UILabel!
}
- 最後に、UITableViewを使用する場合は、UIViewControllerでモデルクラスを使用します。
class RNInviteVC: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet var inviteTableView: UITableView!
@IBOutlet var btnInvite: UIButton!
var checkArray : NSMutableArray = NSMutableArray()
var userName : NSMutableArray = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
btnInvite.layer.borderWidth = 1.5
btnInvite.layer.cornerRadius = btnInvite.frame.height / 2
btnInvite.layer.borderColor = hexColor(hex: "#512DA8").cgColor
var userName1 =["Olivia","Amelia","Emily","Isla","Ava","Lily","Sophia","Ella","Jessica","Mia","Grace","Evie","Sophie","Poppy","Isabella","Charlotte","Freya","Ruby","Daisy","Alice"]
self.userName.removeAllObjects()
for items in userName1 {
print(items)
let model = RNCheckedModel()
model.user_name = items
model.is_check = false
self.userName.add(model)
}
}
@IBAction func btnInviteClick(_ sender: Any) {
}
func tableView(_ tableView: UITableView, numberOfRowsInSection
section: Int) -> Int {
return userName.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: InviteCell = inviteTableView.dequeueReusableCell(withIdentifier: "InviteCell", for: indexPath) as! InviteCell
let image = UIImage(named: "ic_unchecked")
cell.imgProfileImage.layer.borderWidth = 1.0
cell.imgProfileImage.layer.masksToBounds = false
cell.imgProfileImage.layer.borderColor = UIColor.white.cgColor
cell.imgProfileImage.layer.cornerRadius = cell.imgProfileImage.frame.size.width / 2
cell.imgProfileImage.clipsToBounds = true
let model = self.userName[indexPath.row] as! RNCheckedModel
cell.lblName.text = model.user_name
if (model.is_check) {
cell.btnCheck.setImage(UIImage(named: "ic_checked"), for: UIControlState.normal)
}
else {
cell.btnCheck.setImage(UIImage(named: "ic_unchecked"), for: UIControlState.normal)
}
cell.btnCheck.tag = indexPath.row
cell.btnCheck.addTarget(self, action: #selector(self.btnCheck(_:)), for: .touchUpInside)
cell.btnCheck.isUserInteractionEnabled = true
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 80
}
@objc func btnCheck(_ sender: UIButton) {
let tag = sender.tag
let indexPath = IndexPath(row: tag, section: 0)
let cell: InviteCell = inviteTableView.dequeueReusableCell(withIdentifier: "InviteCell", for: indexPath) as! InviteCell
let model = self.userName[indexPath.row] as! RNCheckedModel
if (model.is_check) {
model.is_check = false
cell.btnCheck.setImage(UIImage(named: "ic_unchecked"), for: UIControlState.normal)
checkArray.remove(model.user_name)
if checkArray.count > 0 {
btnInvite.setTitle("Invite (\(checkArray.count))", for: .normal)
print(checkArray.count)
UIView.performWithoutAnimation {
self.view.layoutIfNeeded()
}
} else {
btnInvite.setTitle("Invite", for: .normal)
UIView.performWithoutAnimation {
self.view.layoutIfNeeded()
}
}
}else {
model.is_check = true
cell.btnCheck.setImage(UIImage(named: "ic_checked"), for: UIControlState.normal)
checkArray.add(model.user_name)
if checkArray.count > 0 {
btnInvite.setTitle("Invite (\(checkArray.count))", for: .normal)
UIView.performWithoutAnimation {
self.view.layoutIfNeeded()
}
} else {
btnInvite.setTitle("Invite", for: .normal)
}
}
self.inviteTableView.reloadData()
}
func hexColor(hex:String) -> UIColor {
var cString:String = hex.trimmingCharacters(in: .whitespacesAndNewlines).uppercased()
if (cString.hasPrefix("#")) {
cString.remove(at: cString.startIndex)
}
if ((cString.count) != 6) {
return UIColor.gray
}
var rgbValue:UInt32 = 0
Scanner(string: cString).scanHexInt32(&rgbValue)
