ios - 错误的键盘隐藏

Question

我有一些奇怪的问题tableView.keyboardDismissMode = .onDrag。轻按时我会抬起视线，textField这没关系。然后我想像在 iMessage 中一样关闭我的键盘，但在我的情况下，当keyboardWillHide通知调用view.frame.origin.y不等于 0。它等于 12。有趣的是我的代码在模拟器中工作得非常酷，但这个错误只在真正的 iPhone 11 上。任何想法到底是什么是吗？

我的带有键盘通知的代码

@objc func keyboardWillShow(notification: NSNotification) {
            if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
                self.view.frame.origin.y = -keyboardSize.size.height + (self.tabBarController?.tabBar.bounds.height)!
            }
        }
        
     @objc func keyboardWillHide(notification: NSNotification) {
            self.view.frame.origin.y = 0
      }

我找到了解决方案。麻烦是因为keyboardWillShow 多次调用。处理它的代码。

@objc func keyboardWillShow(notification: NSNotification) {
        var _kbSize:CGSize!
        
        if let info = notification.userInfo {
            
            let frameEndUserInfoKey = UIResponder.keyboardFrameEndUserInfoKey
            
            //  Getting UIKeyboardSize.
            if let kbFrame = info[frameEndUserInfoKey] as? CGRect {
                
                let screenSize = UIScreen.main.bounds
                
                let intersectRect = kbFrame.intersection(screenSize)
                
                if intersectRect.isNull {
                    _kbSize = CGSize(width: screenSize.size.width, height: 0)
                } else {
                    _kbSize = intersectRect.size
                }
                
                if _kbSize.height != 0 {
                    self.view.frame.origin.y = -_kbSize.height + (self.tabBarController?.tabBar.bounds.height)!
                } else {
                    self.view.frame.origin.y = 0
                }
            }
        }
    }
