Swift 在自定义单元格类中禁用collectionView用户交互或滚动,swift,uicollectionview,Swift,Uicollectionview,我在根视图中有一个UICollectionView UICollectionView有一个名为HomeCell的自定义单元格 let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath as IndexPath) as!

我在根视图中有一个

UICollectionView

UICollectionView

有一个名为

HomeCell

的自定义单元格

let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath as IndexPath) as! HomeCell

在HomeCell中，我添加了如下视图和标题：

HomeCell类：

class HomeCell: UICollectionViewCell {

var bgView = UIView()
var title = UILabel()

override init(frame: CGRect) {
    super.init(frame: frame)

    bgView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
    bgView.layer.cornerRadius = 20.0
    bgView.backgroundColor = UIColor.gray

    title.text = "Test"
    title.textAlignment = .center
    title.frame = CGRect(x: 0, y: 210, width: 200, height: 40)
    title.textColor = .black

    let tap = UITapGestureRecognizer(target: self, action: #selector(self.handleTapCollapse(_:)))
    bgView.addGestureRecognizer(tap)

    self.addSubview(bgView)
    self.addSubview(title)
}

@objc func handleTapCollapse(_ sender: UITapGestureRecognizer) {

    print("disabled")
    // her I want to disable my collectionView

}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}
 }

我想在触摸我的bgView时禁用

UICollectionView

滚动

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath as IndexPath) as! HomeCell
    cell.collectionView = collectionView
}

我在

中尝试了didSelectItemAt

，但没有成功

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    if indexPath.row == 1 {
        animateCamerCell()
    }
}

可能吗？如果没有，这个问题的解决方案是什么

首先在您的单元格中创建如下协议

protocol touchDelegate:class {
func DidTap(OnView view:UIView,with tap:UITapGestureRecognizer)
}

class HomeCell: UICollectionViewCell {

var bgView = UIView()
var title = UILabel()

weak var delegate:touchDelegate? 

override init(frame: CGRect) {
super.init(frame: frame)

bgView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
bgView.layer.cornerRadius = 20.0
bgView.backgroundColor = UIColor.gray

title.text = "Test"
title.font = UIFont(name: "IRANSansFaNum", size: 18)
title.textAlignment = .center
title.frame = CGRect(x: 0, y: 210, width: 200, height: 40)
title.textColor = .black

let tap = UITapGestureRecognizer(target: self, action: #selector(self.handleTapCollapse(_:)))
bgView.addGestureRecognizer(tap)

self.addSubview(bgView)
self.addSubview(title)
}

@objc func handleTapCollapse(_ sender: UITapGestureRecognizer) {

print("disabled")
delegate?.DidTap(OnView: tap.view, with:sender)

}

required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}

现在到你的控制器确认协议

class yourcontroller:UIViewController, touchDelegate{
}

现在对数据源方法进行如下更改

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath as IndexPath) as! HomeCell
    cell.delegate = self
}

并在控制器中实现委托方法

func DidTap(OnView view:UIView,with tap:UITapGestureRecognizer){
   self.yourcollectionviewVariable.isScrollEnabled = false
}

首先像这样在你的细胞里制定协议

protocol touchDelegate:class {
func DidTap(OnView view:UIView,with tap:UITapGestureRecognizer)
}

class HomeCell: UICollectionViewCell {

var bgView = UIView()
var title = UILabel()

weak var delegate:touchDelegate? 

override init(frame: CGRect) {
super.init(frame: frame)

bgView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
bgView.layer.cornerRadius = 20.0
bgView.backgroundColor = UIColor.gray

title.text = "Test"
title.font = UIFont(name: "IRANSansFaNum", size: 18)
title.textAlignment = .center
title.frame = CGRect(x: 0, y: 210, width: 200, height: 40)
title.textColor = .black

let tap = UITapGestureRecognizer(target: self, action: #selector(self.handleTapCollapse(_:)))
bgView.addGestureRecognizer(tap)

self.addSubview(bgView)
self.addSubview(title)
}

@objc func handleTapCollapse(_ sender: UITapGestureRecognizer) {

print("disabled")
delegate?.DidTap(OnView: tap.view, with:sender)

}

required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}

现在到你的控制器确认协议

class yourcontroller:UIViewController, touchDelegate{
}

现在对数据源方法进行如下更改

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath as IndexPath) as! HomeCell
    cell.delegate = self
}

并在控制器中实现委托方法

func DidTap(OnView view:UIView,with tap:UITapGestureRecognizer){
   self.yourcollectionviewVariable.isScrollEnabled = false
}

您可以在不使用任何

协议的情况下执行此操作
您可以使用当前UICollectionview
的weak
变量，并在handleapcollapse函数中禁用滚动
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath as IndexPath) as! HomeCell
    cell.collectionView = collectionView
}

在HomeCell
中：
class HomeCell: UICollectionViewCell {

    weak var collectionView:UICollectionView?

    override init(frame: CGRect) {
        super.init(frame: frame)

    }
    @objc func handleTapCollapse(_ sender: UITapGestureRecognizer) {
        print("disabled")
        collectionView?.isScrollEnabled = false
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

}

是的，有可能collectionview.isScrollEnabled=false
@RahulGUsai不在func handleTapCollapse中工作。您可以添加协议以将触摸事件传输到控制器。有可能collectionview.isScrollEnabled=false
