iOS自定义视图(.XIB)按钮绑定不工作

Question

protocol CustomViewAction: class {
func customActionButton(_ sender: UIButton)
}
class MainFooter: UIView { 
weak var delegate: CustomViewAction?
@IBAction func languageButton(_ sender: UIButton) {
self.delegate?.customActionButton(sender)
} 
private func loadNib() {...}
}

class MainCont: CustomViewAction {
...
let mainFooter = MainFooter()
mainFooter.frame = view.frame
mainFooter.delegate = self
func customActionButton(_ sender: UIButton) {
... not working
}
}

有自定义视图。在主控制器中实现的自定义动作按钮界面。此代码不起作用。。。为什么？

Answer 1

这是非常糟糕的代码(请修正

protocol CustomViewDelegate: class {
func actionTouchCustomView(button:UIButton)
}

class MainFooterView: UIView { 
weak var delegate: CustomViewDelegate?
//MARK: Handle Actions
@IBAction func handleTouchActionLanguageButton(_ sender: UIButton) {
self.delegate?.actionTouchCustomView(sender)
} 
//MARK: Life cycle
private func loadNib() {...}
}
class MainCont: CustomViewDelegate {
...
let mainFooter = MainFooter()
mainFooter.frame = view.frame
mainFooter.delegate = self
//MARK -  CustomViewDelegate
func actionTouchCustomView(button:UIButton) {
... not working
}
}

1. 在XIB或情节提要中检查链接按钮操作
2. 检查寿命"let mainFooter"。也许物体已经死了
