UITapGesture在堆栈视图中的xib文件上不起作用

Question

我有一个带有这些物品的控制器

在堆栈视图中，我动态添加一个或多个xib文件作为UiView，这是我的xib文件代码：

class PassengerInfoItem: UIView {
@IBOutlet weak var View_Content: UIView!
@IBOutlet weak var Label_AddPassenger: UILabel!


override init(frame: CGRect)
{
    super.init(frame: frame)
    self.commenInit()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    self.commenInit()
}

func commenInit()
{
    Bundle.main.loadNibNamed("PassengerInfoItem", owner: self, options: nil)
    self.View_Content.frame = self.bounds
    self.View_Content.autoresizingMask = [.flexibleHeight, .flexibleWidth]
    addSubview(self.View_Content)
}}

这是我的控制器代码：

for i in 1...(UserSearchModel.Passengers.AdultNumber)!
    {
        let passengerInfoItem = PassengerInfoItem()
        passengerInfoItem.tag = i
        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.handleTapGesture_PassengerInfo))
        tapGestureRecognizer.delegate = self
        passengerInfoItem.addGestureRecognizer(tapGestureRecognizer)
        self.StackView_AddPassengerInfo.addArrangedSubview(passengerInfoItem)
    }

在堆栈视图中，所有passportInfoItem已成功添加，但是当触摸其中的任何一项均未发生并且我的问题是UITapGestureRecognizer无法正常工作时，我检查了所有isUserInteractionEnabled = true的后视图，滚动视图，卡片，堆栈视图，但UITapGesture不起作用< / p>

因为您在此处添加了另一个实例

 Bundle.main.loadNibNamed("PassengerInfoItem", owner: self, options: nil)
self.View_Content.frame = self.bounds
self.View_Content.autoresizingMask = [.flexibleHeight, .flexibleWidth]
addSubview(self.View_Content)

因此该手势已应用于最背面的视图，您可能需要

class func getInstance() ->  PassengerInfoItem {
   let vv =  Bundle.main.loadNibNamed("PassengerInfoItem", owner: self, options: nil)?.first! as!  PassengerInfoItem
   return vv
}

然后替换

let passengerInfoItem = PassengerInfoItem()

使用

let passengerInfoItem = PassengerInfoItem.getInstance()
