iOS如何知道哪个按钮按下了CollectionView与自定义委托

Question

所以我在一个集合视图中有一个单元格,里面有3个按钮.为了使用这些按钮触发代码,我实现了一个自定义委托.现在代码被触发,但我不知道代码触发了哪个单元格.我怎样才能最好地实现这一点？这是我的一些代码.协议:

protocol OverViewDelegate {
func registerButtonClicked()
func evaluateButtonClicked()
func overviewButtonClicked()
}

cellForItemAt:

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "sessionCell", for: indexPath) as? SessionCollectionViewCell
    let session: SessionModel
    session = DebugData.shared.sessionArray[indexPath.row]

    cell?.sessionImage.image = #imageLiteral(resourceName: "carControl")
    cell?.sessionNameLabel.text = session.name
    cell?.sessionLocationLabel.text = session.location
    cell?.overViewDelegate = self

    return cell!
}

细胞:

import UIKit

导入IBAnimatable

@IBOutlet weak var sessionImage: UIImageView!
@IBOutlet weak var sessionNameLabel: UILabel!
@IBOutlet weak var sessionLocationLabel: UILabel!
@IBOutlet weak var sessionRegisterButton: AnimatableButton!
@IBOutlet weak var sessionOverviewButton: AnimatableButton!
@IBOutlet weak var sessionEvaluateButton: AnimatableButton!

var overViewDelegate: OverViewDelegate?

@IBAction func registerButtonClicked(_ sender: Any) {
    overViewDelegate?.registerButtonClicked()
}

@IBAction func overviewButtonClicked(_ sender: Any) {
    overViewDelegate?.overviewButtonClicked()
}

@IBAction func evaluateButtonClicked(_ sender: Any) {
    overViewDelegate?.evaluateButtonClicked()
}

任何帮助都会得到满足.

Answer 1

在Cell类中传递indexPath值返回按钮单击功能上的indexPath

协议:-

protocol OverViewDelegate {
func registerButtonClicked(_ indexPath : IndexPath)
func evaluateButtonClicked(_ indexPath : IndexPath)
func overviewButtonClicked(_ indexPath : IndexPath)
}

cellForItemAt:

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "sessionCell", for: indexPath) as? SessionCollectionViewCell
        let session: SessionModel
        session = DebugData.shared.sessionArray[indexPath.row]

        cell?.sessionImage.image = #imageLiteral(resourceName: "carControl")
        cell?.sessionNameLabel.text = session.name
        cell?.sessionLocationLabel.text = session.location
        cell?.overViewDelegate = self
        cell?.indexPath = indexPath

        return cell!
    }

细胞:

@IBOutlet weak var sessionImage: UIImageView!
@IBOutlet weak var sessionNameLabel: UILabel!
@IBOutlet weak var sessionLocationLabel: UILabel!
@IBOutlet weak var sessionRegisterButton: AnimatableButton!
@IBOutlet weak var sessionOverviewButton: AnimatableButton!
@IBOutlet weak var sessionEvaluateButton: AnimatableButton!

var overViewDelegate: OverViewDelegate?
var indexPath : IndexPath?

@IBAction func registerButtonClicked(_ sender: Any) {
    overViewDelegate?.registerButtonClicked(indexPath)
}

@IBAction func overviewButtonClicked(_ sender: Any) {
    overViewDelegate?.overviewButtonClicked(indexPath)
}

@IBAction func evaluateButtonClicked(_ sender: Any) {
    overViewDelegate?.evaluateButtonClicked(indexPath)
}

得到细胞使用: -

let cell = tableView.cellForRow(at: indexPath)
