Swift - 未检测到在自定义单元格中移动滑块的事件

Question

我正在使用以下界面在swift 3中开发一个应用程序：

我必须添加一些关于传奇的细节。图例包含两个视图（firstView和secondView）。默认的“布局”为0，直到我们点击它，然后打开单元格的细节。贝尔斯，这样的传奇出现了：

目前滑块发送事件如下：

界面由两个视图组成。作为底部视图的地图（“MainMapVC”），如果我们向右滑动，则显示由自定义单元格（“customCell”）形成的地图“LefSideViewController”的图例。 我附上三个类的代码：

“customCell”：

导入UIKit

protocol customCellDelegate {
    func didTappedSwicht(cell: customCell)
    func didMoveSlider(cell: customCell)
}

class customCell: UITableViewCell {

//MARK: OUTLETS VIEW 1
@IBOutlet weak var firstView: UIView!
@IBOutlet weak var firstViewLabel: UILabel!
@IBOutlet weak var swichtActiveLayer: UISwitch!


//MARK: OUTLETS VIEW 2
@IBOutlet weak var secondView: UIView!
@IBOutlet weak var secondViewLabel: UILabel!
@IBOutlet weak var secondHeightConstraint: NSLayoutConstraint!
@IBOutlet weak var idDeliveryResponse: UILabel!
@IBOutlet weak var minRangeDeliveryResponse: UILabel!
@IBOutlet weak var maxRangeDeliveryResponse: UILabel!
@IBOutlet weak var initialMinDeliveryResponse: UILabel!
@IBOutlet weak var initialMaxDeliveryResponse: UILabel!
@IBOutlet weak var sliderOpacity: UISlider!


// MARK: VARIABLES
var delegate: customCellDelegate!

override func awakeFromNib() {
    super.awakeFromNib()
}


func setupWithModel(model: deliveriesLeftTableModel){
    firstViewLabel.text = model.firstViewLabel
    secondViewLabel.text = model.secondViewLabel
    idDeliveryResponse.text = model.idDeliveryResponse
    minRangeDeliveryResponse.text = model.minRangeDeliveryResponse
    maxRangeDeliveryResponse.text = model.maxRangeDeliveryResponse
    initialMinDeliveryResponse.text = model.initialMinDeliveryResponse
    initialMaxDeliveryResponse.text = model.initialMaxDeliveryResponse
    swichtActiveLayer.setOn(model.swichtActiveLayer, animated: true)
    sliderOpacity.value = model.sliderOpacity

}


@IBAction func swichtValueChanged(_ sender: Any) {
    delegate.didTappedSwicht(cell: self)
}


@IBAction func primaryActionTrigger(_ sender: Any){
    print("primaryActionTrigger")
}

@IBAction func touchUpInside(_ sender: Any){
    print("touchUpInside")
}

/*@IBAction func sliderValueChanged(_ sender: Any) {
    delegate.didMoveSlider(cell: self)
}*/


var showsDetails = false {
    didSet {
        secondHeightConstraint.priority = showsDetails ? 250 : 900
    }
}

}

“LefSideViewController”是：

import UIKit

protocol customCellDelegate {
    func didTappedSwicht(cell: customCell)
    func didMoveSlider(cell: customCell)
}

class customCell: UITableViewCell {

//MARK: OUTLETS VIEW 1

@IBOutlet weak var firstViewLabel: UILabel!
@IBOutlet weak var swichtActiveLayer: UISwitch!


//MARK: OUTLETS VIEW 2
@IBOutlet weak var secondView: UIView!
@IBOutlet weak var secondViewLabel: UILabel!
@IBOutlet weak var secondHeightConstraint: NSLayoutConstraint!
@IBOutlet weak var idDeliveryResponse: UILabel!
@IBOutlet weak var minRangeDeliveryResponse: UILabel!
@IBOutlet weak var maxRangeDeliveryResponse: UILabel!
@IBOutlet weak var initialMinDeliveryResponse: UILabel!
@IBOutlet weak var initialMaxDeliveryResponse: UILabel!
@IBOutlet weak var sliderOpacity: UISlider!


// MARK: VARIABLES
var delegate: customCellDelegate!

override func awakeFromNib() {
    super.awakeFromNib()
}


func setupWithModel(model: deliveriesLeftTableModel){
    firstViewLabel.text = model.firstViewLabel
    secondViewLabel.text = model.secondViewLabel
    idDeliveryResponse.text = model.idDeliveryResponse
    minRangeDeliveryResponse.text = model.minRangeDeliveryResponse
    maxRangeDeliveryResponse.text = model.maxRangeDeliveryResponse
    initialMinDeliveryResponse.text = model.initialMinDeliveryResponse
    initialMaxDeliveryResponse.text = model.initialMaxDeliveryResponse
    swichtActiveLayer.setOn(model.swichtActiveLayer, animated: true)
    sliderOpacity.value = model.sliderOpacity

}


@IBAction func swichtValueChanged(_ sender: Any) {
    delegate.didTappedSwicht(cell: self)
}



@IBAction func sliderValueChanged(_ sender: Any) {
    delegate.didMoveSlider(cell: self)
}



var showsDetails = false {
    didSet {
        secondHeightConstraint.priority = showsDetails ? 250 : 900
    }
}

}

应用程序与协议和代理进行通信。例如，当我们点击图例的swicht时，类“customCell”能够检测到事件“swichtValueChanged”并将其发送到“didSappedSwicht”委托“LeftSideViewController”，但是当我们移动滑块时“customCell” “类不能检测到事件”sliderValueChanged“并使事件关闭视图（因为左边的图例左侧是向左滑动关闭的。）

如何使其检测滑块事件而不关闭视图？ 谢谢

Answer 1

您应该将Slider绑定到两个事件＆＃34; 触发主要操作＆＃34;和＆＃34; 触摸内部＆＃34;

这里我附上了图片供你参考

并删除此方法上的左滑动和右滑动手势

方法描述和代码

1＆＃34;触发主要操作＆＃34;

单击滑块时，该方法将调用＆＃34;触发主要操作＆＃34;

注意：停用手势

（UISwipeGestureRecognizerDirection.right和UISwipeGestureRecognizerDirection.left）

2 Touch Up Inside

注意：同时启用手势

（UISwipeGestureRecognizerDirection.right和UISwipeGestureRecognizerDirection.left）
