ios - KeyboardWillHide 在 KeyboardWillShow 仍在动画时被调用

Question

目前我有一个 View 在键盘显示或隐藏时使用键盘进行动画处理。我添加了一个手势识别器，这样当用户点击键盘时它就会消失。

我遇到的问题是，如果用户在键盘出现时点击以降低键盘，键盘就会消失，我的 View 不会降低。我实际上注意到，无论出于何种原因，视野都变得更高了。

这是我的键盘监听器方法:

func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
        if let tabBarController = tabBarController {
            responseNode.frame.origin.y -= keyboardSize.height-tabBarController.tabBar.frame.height
            tableNode.view.contentInset.bottom += keyboardSize.height-tabBarController.tabBar.frame.height
        }
    }
}
func keyboardWillHide(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
        if let tabBarController = tabBarController {
            responseNode.frame.origin.y += keyboardSize.height-tabBarController.tabBar.frame.height
            tableNode.view.contentInset.bottom -= keyboardSize.height-tabBarController.tabBar.frame.height
        }
    }
}

这是我隐藏键盘的方法:

extension UIViewController {
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
        view.addGestureRecognizer(tap)
    }

    func dismissKeyboard() {
        view.endEditing(true)
    }
}

如有任何帮助，我们将不胜感激!

试试这个

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
   self.view.endEditing(true)
 }

func textFieldShouldReturn(textField: UITextField) -> Bool {

    text.resignFirstResponder()

    return true

}
