如果我在 swift 中添加 UITapGestureRecognizer，则 UIButton 单击事件不起作用

问题描述

在我的登录页面上，如果我专注于 UITextEdit 以输入电子邮件和密码，则会出现键盘并向上滚动登录页面.如果我触摸键盘外部，我会添加此代码以删除键盘.

On my login page, if I focus to UITextEdit for entering email and password, keyboard appears and login page scroll up. And I add this code for remove keyboard if I touch outside of keyboard.

extension UIViewController {
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }
    
    @objc func dismissKeyboard() {
        view.endEditing(true)
        UIView.animate(withDuration: 0.3, animations: {
            self.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height)
        })
    }
}

在我的 viewDidLoad() 函数中，我是这样添加的.

And on my viewDidLoad() function, I added it like this.

override func viewDidLoad() 
{
        super.viewDidLoad()
        //TODO
        self.hideKeyboardWhenTappedAround()
       ...
}

效果很好，但是如果我在键盘仍然打开时单击登录按钮，dismisskeyboard() 函数可以工作，但 btnClick 函数不起作用.

It works well, But If I click login button when keyboard is still opening, dismisskeyboard() function works but btnClick function doesn't work.

@IBAction func LoginBtnClick(_ sender: Any) 
{
        print("loginBtn")
        //...
}

我该如何解决这个问题?

How can I solve this problem?

推荐答案

不要在主viewController的视图中添加手势 在UIButton下面添加全屏子视图并添加手势

Don't add the gesture to main viewController's view add a full screen subview below UIButton and add the gesture to it
