ios - 带有辅助类的 xib 文件按钮不起作用

Question

我有一个 xib 文件，里面有一个按钮，按钮上有两个标签，隐藏在 if 语句中，我想要做的是在我的帮助方法中调用一个名为 pledgeInterestView 的函数，它是一个alertView，我有向按钮添加了一个目标，然后向父 View 添加了一个手势识别器(该 View 封装了标签和按钮)，但是按钮无法正常工作并且函数没有被调用？我的 xib 文件很好并且加载完美，如果需要该代码我可以提供它

这是我的辅助方法:

static func inflateProfileImageFunder(view:UIView){
    let content = ProfileImage()
    view.addSubview(content)
    content.translatesAutoresizingMaskIntoConstraints = false
    let leadingDeviceData = NSLayoutConstraint(item: content, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1, constant: 0)
    let trailingDeviceData = NSLayoutConstraint(item: content, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1, constant: 0)
    let heightDeviceData = NSLayoutConstraint(item: content, attribute: .height, relatedBy: .equal, toItem: view, attribute: .height, multiplier: 1, constant: 0)
    let topDeviceData = NSLayoutConstraint(item: content, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1, constant: 0)
    NSLayoutConstraint.activate([leadingDeviceData, trailingDeviceData, heightDeviceData, topDeviceData])

    let isFunder = LoginVC.isFunder
        if (!isFunder){
            print("Not a Funder")
            content.buttonViews.translatesAutoresizingMaskIntoConstraints = false
            content.buttonViews.heightAnchor.constraint(equalToConstant: 0).isActive = true
            content.buttonViews.isHidden = true
        }else{
            content.label2.isHidden = true
            content.label1.isHidden = true
            content.buttonTap.isEnabled = true
            content.buttonTap.setTitle("Pledge Interest", for: UIControlState.normal)
            content.buttonTap.setTitleColor(#colorLiteral(red: 1, green: 1, blue: 1, alpha: 1), for: UIControlState.normal)
            let tap = UITapGestureRecognizer(target: self, action: #selector(self.pledgeInterestView(_:)))
            content.buttonViews.addGestureRecognizer(tap)
            content.buttonViews.isUserInteractionEnabled = true
    }
}
func pledgeInterestView(_ sender: UITapGestureRecognizer){
    let content = PledgeInterest()

    content.translatesAutoresizingMaskIntoConstraints = false
    content.heightAnchor.constraint(equalToConstant: 175).isActive = true
    let attributedString = NSAttributedString(string: "I can Provide", attributes: [
        NSForegroundColorAttributeName : #colorLiteral(red: 0.1657446325, green: 0.3779471517, blue: 0.6579626203, alpha: 1)
        ])
    let alert = AlertController(title: "", message: "")
    alert.setValue(attributedString, forKey: "attributedTitle")


    let okAction = AlertAction(title: "Pledge", style: .normal, handler: nil)
    let cancelAction = AlertAction(title: "Cancel", style: .normal, handler: nil)

    alert.add(cancelAction)
    alert.add(okAction)
    alert.contentView.addSubview(content)

    content.leftAnchor.constraint(equalTo: alert.contentView.leftAnchor).isActive = true
    content.rightAnchor.constraint(equalTo: alert.contentView.rightAnchor).isActive = true
    content.centerXAnchor.constraint(equalTo: alert.contentView.centerXAnchor).isActive = true
    content.topAnchor.constraint(equalTo:alert.contentView.topAnchor).isActive = true
    content.bottomAnchor.constraint(equalTo: alert.contentView.bottomAnchor).isActive = true


    alert.view.tintColor = #colorLiteral(red: 0.1657446325, green: 0.3779471517, blue: 0.6579626203, alpha: 1)
    alert.present(alert, animated: true)
}

The code for my Xib file, the buttonView has 3 elements inside it, 2 labels and 1 button

the view I am trying to add a tap to(ProfileImage)

我终于解决了这个问题，只需在我的帮助器类中添加一个额外的静态函数，如下所示:

 static func inflateProfileImageFunder(view:UIView) {
    let content = ProfileImage()
    view.addSubview(content)
    content.translatesAutoresizingMaskIntoConstraints = false
    let leadingDeviceData = NSLayoutConstraint(item: content, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1, constant: 0)
    let trailingDeviceData = NSLayoutConstraint(item: content, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1, constant: 0)
    let heightDeviceData = NSLayoutConstraint(item: content, attribute: .height, relatedBy: .equal, toItem: view, attribute: .height, multiplier: 1, constant: 0)
    let topDeviceData = NSLayoutConstraint(item: content, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1, constant: 0)
    NSLayoutConstraint.activate([leadingDeviceData, trailingDeviceData, heightDeviceData, topDeviceData])

    let isFunder = LoginVC.isFunder
        if (!isFunder){
            print("Not a Funder")
            content.buttonViews.translatesAutoresizingMaskIntoConstraints = false
            content.buttonViews.heightAnchor.constraint(equalToConstant: 0).isActive = true
            content.buttonViews.isHidden = true
        }else{
            content.label2.isHidden = true
            content.label1.isHidden = true
            content.buttonTap.isEnabled = true
            content.buttonTap.setTitle("Pledge Interest", for: UIControlState.normal)
            content.buttonTap.setTitleColor(#colorLiteral(red: 1, green: 1, blue: 1, alpha: 1), for: UIControlState.normal)
            content.buttonTap.addTarget(self, action: #selector(pledgeInterestView), for: UIControlEvents.touchUpInside)
    }
}

static func pledgeInterestView(){
    pledge()
}

static func pledge() {
    let content = PledgeInterest()

    content.translatesAutoresizingMaskIntoConstraints = false
    content.heightAnchor.constraint(equalToConstant: 175).isActive = true
    let attributedString = NSAttributedString(string: "I can Provide", attributes: [
        NSForegroundColorAttributeName : #colorLiteral(red: 0.1657446325, green: 0.3779471517, blue: 0.6579626203, alpha: 1)
        ])
    let alert = AlertController(title: "", message: "")
    alert.setValue(attributedString, forKey: "attributedTitle")

    let okAction = AlertAction(title: "Pledge", style: .normal, handler: nil)
    let cancelAction = AlertAction(title: "Cancel", style: .normal, handler: nil)

    alert.add(cancelAction)
    alert.add(okAction)
    alert.contentView.addSubview(content)

    content.leftAnchor.constraint(equalTo: alert.contentView.leftAnchor).isActive = true
    content.rightAnchor.constraint(equalTo: alert.contentView.rightAnchor).isActive = true
    content.centerXAnchor.constraint(equalTo: alert.contentView.centerXAnchor).isActive = true
    content.topAnchor.constraint(equalTo:alert.contentView.topAnchor).isActive = true
    content.bottomAnchor.constraint(equalTo: alert.contentView.bottomAnchor).isActive = true

    alert.view.tintColor = #colorLiteral(red: 0.1657446325, green: 0.3779471517, blue: 0.6579626203, alpha: 1)

    alert.present()

}

这对我来说非常有效
