Swift-除非长时间点按，否则按钮的操作不会被触发

如何解决Swift-除非长时间点按，否则按钮的操作不会被触发

我在Sign in with Apple中添加了一个UIScrollView按钮，就像苹果文档中所建议的那样；

let signInWithAppleButton = ASAuthorizationAppleIDButton(type: .default,style: .white)
            
signInWithAppleButton.addTarget(self,action: #selector(loginWithApple(_:)),for: .touchUpInside)
signInWithAppleButton.cornerRadius = 12
            
scrollView.addSubview(signInWithAppleButton)

问题是，该按钮仅对非常长的按下响应，而不是简单的点击。我试过将其放在UIScrollView之外，并且在其中起作用！

这是我的UIScrollView和按钮的设置；

fileprivate func setupScrollViewConstraints() {
    scrollView.translatesAutoresizingMaskIntoConstraints = false
    
    NSLayoutConstraint.activate([
        scrollView.topAnchor.constraint(equalTo: self.view.topAnchor),scrollView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor),scrollView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),scrollView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor)
    ])
}

func setupSignInWithAppleButton() -> UIControl? {
    if #available(iOS 13.0,*) {
        let signInWithAppleButton = ASAuthorizationAppleIDButton(type: .default,style: .white)
        
        signInWithAppleButton.addTarget(self,for: .touchUpInside)
        signInWithAppleButton.cornerRadius = 12
        
        scrollView.addSubview(signInWithAppleButton)
        
        signInWithAppleButton.translatesAutoresizingMaskIntoConstraints = false
        
        NSLayoutConstraint.activate([
            signInWithAppleButton.topAnchor.constraint(equalTo: accountLabel.bottomAnchor,constant: 8),signInWithAppleButton.centerXAnchor.constraint(equalTo: scrollView.centerXAnchor),signInWithAppleButton.widthAnchor.constraint(equalToConstant: 210),signInWithAppleButton.heightAnchor.constraint(equalToConstant: 45)
        ])
        
        return signInWithAppleButton
    }
    
    return nil
}

任何想法都在破坏它吗？

编辑； 这是我的处理程序；

@objc private func loginWithApple(_ sender: Any) {
    let appleIDProvider = ASAuthorizationAppleIDProvider()
        
    let request = appleIDProvider.createRequest()
    request.requestedScopes = [.fullName,.email]
        
    let authorizationController = ASAuthorizationController(authorizationRequests: [request])
        
    authorizationController.delegate = self
    authorizationController.presentationContextProvider = self
    authorizationController.performRequests()
}

我已经在其中放置了一个断点，但是只有长按按钮才能激活它！只是提醒一下，如果将按钮放在控制器的视图内，该按钮将按预期工作！

解决方法

我只是尝试将signInWithAppleButton添加到UIScorllview中，如下所示：

@objc func loginWithApple(_ sender: Any) {
    print("loginWithApple")
}

fileprivate func setupScrollViewConstraints() {
    scrollView.translatesAutoresizingMaskIntoConstraints = false

    NSLayoutConstraint.activate([
        scrollView.topAnchor.constraint(equalTo: self.view.topAnchor),scrollView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor),scrollView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),scrollView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor)
    ])
}

func setupSignInWithAppleButton() -> UIControl? {
    if #available(iOS 13.0,*) {
        let signInWithAppleButton = ASAuthorizationAppleIDButton(type: .default,style: .white)

        signInWithAppleButton.addTarget(self,action: #selector(loginWithApple(_:)),for: .touchUpInside)
        signInWithAppleButton.cornerRadius = 12

        scrollView.addSubview(signInWithAppleButton)

        signInWithAppleButton.translatesAutoresizingMaskIntoConstraints = false

        NSLayoutConstraint.activate([
            signInWithAppleButton.centerYAnchor.constraint(equalTo: scrollView.centerYAnchor),signInWithAppleButton.centerXAnchor.constraint(equalTo: scrollView.centerXAnchor),signInWithAppleButton.widthAnchor.constraint(equalToConstant: 210),signInWithAppleButton.heightAnchor.constraint(equalToConstant: 45)
        ])

        return signInWithAppleButton
    }

    return nil
 }

我没有遇到任何问题，点击该按钮后，会立即为我打印“ loginWithApple ”。该按钮的行为与其他UIButton相同。我没发现任何问题。

您在loginWithApple中做什么？使用您提供的最少代码，我预计loginWithApple函数中可能会出现一些问题，可能会延迟您的期望。

更新： 下面是行为。请注意，UIScrollView中的按钮。另外，在设备上也没有延迟。

我终于想通了！！！我在滚动视图中添加了一个轻击手势，因此点击时可以关闭键盘！由于某种原因，它仅中断了Apple的登录按钮触摸事件！
