TextFiled鍵盤問題

Question

我正在研究具有註釋和用戶的應用程序，我需要用戶將註釋插入到表格視圖中，我面臨的問題是關於鍵盤的位置，當用戶按下文本時字段來編寫鍵盤出現的註釋和文本字段，如下面的代碼所示。

但問題是，當我更改鍵盤的語言，將鍵盤更改爲表情符號或打開autocorrection覆蓋的文本字段，將不會隨鍵盤佈局移動。

override func viewWillAppear(animated: Bool) { 

    super.viewWillAppear(animated) 

    // KeyBoard Show and Hide 

    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(Commants_Page.keyboardWillShow(_:)), name: UIKeyboardWillShowNotification, object:nil) 
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(Commants_Page.keyboardWillHide(_:)), name: UIKeyboardWillHideNotification, object: nil) 


    NSNotificationCenter.defaultCenter().addObserver(self,selector: #selector(Commants_Page.adjustForKeyboard(_:)),name: UIKeyboardWillChangeFrameNotification,object: nil) 

} 


// KeyBoard Show and Hide Function 

func keyboardWillShow(notification: NSNotification) { 

    if KeyBoardMove == false { 

     if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() { 
      self.view.frame.origin.y -= keyboardSize.height 

      KeyBoardMove = true 
     } 
    } 
} 

func keyboardWillHide(notification: NSNotification) { 

    if KeyBoardMove == true { 

     if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.CGRectValue() { 
      self.view.frame.origin.y += keyboardSize.height 

      KeyBoardMove = false 
     } 
    } 
}

有一次，我面臨着同樣的問題，並找到了解決如下工作。我不確定這是否是完美的解決方案，但它對我的預期工作。所以你可以試試看。

我所做的是：

1. 添加UITextInputCurrentInputModeDidChangeNotification通知，viewWillAppear
2. 實現changeInputMode方法來確定鍵盤類型

3. 手柄keyboardWillShow和keyboardWillHide

   var isEmoji = Bool() 
   
   override func viewWillAppear(animated: Bool) { 
   
   super.viewWillAppear(animated) 
   
   isEmoji = false 
   NSNotificationCenter.defaultCenter().addObserver(self, selector: "changeInputMode:", name:UITextInputCurrentInputModeDidChangeNotification, object: nil) 
   
   } 
   
   func changeInputMode(notification : NSNotification) 
   { 
       //Emoji keyboard does not have any primary language whereas normal text keyboard does have. Therefore, on the bases of it we can determine the keyboard type 
   
       if let lang = txtComment.textInputMode?.primaryLanguage 
       { 
        isEmoji = false 
       } 
       else{ 
        isEmoji = true 
       } 
   } 
   
   func keyboardWillShow(notification: NSNotification) { 
       if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.CGRectValue() { 
        print(isEmoji) 
        if(!isEmoji){     
   
         writeCommentView.frame.origin.y -= keyboardSize.height 
        } 
        else{ 
         writeCommentView.frame.origin.y -= 37 //where 37 is the height differece between normal keyboard and emoji keyboard. Change this value accordingly 
        } 
   
   
       } 
   } 
   
   func keyboardWillHide(notification: NSNotification) { 
       if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() { 
        //Handle this method accordingly. For example.. 
        if(!isEmoji){     
   
         writeCommentView.frame.origin.y += keyboardSize.height 
        } 
        else{ 
         writeCommentView.frame.origin.y += 37 
        } 
       } 
   } 
   

   希望這將有助於。
