iOS12 - 使用WKWebView出現input鍵盤將頁面上頂不下移

• 實際狀況以下圖

鍵盤彈起

鍵盤收起

• 解決辦法：

  • 監聽鍵盤的談起和隱藏

  /// 監聽將要彈起
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyBoardShow) name:UIKeyboardWillShowNotification object:nil];
  /// 監聽將要隱藏
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyBoardHidden) name:UIKeyboardWillHideNotification object:nil];
  複製代碼

  • 監聽方法中設置WKWebView的scrollview的contentOffset

  /** 鍵盤談起屏幕偏移量 */
  @property (nonatomic, assign) CGPoint keyBoardPoint;
  
  #pragma mark - addObserverKeyboard
  /// 鍵盤將要彈起
  - (void)keyBoardShow {
      CGPoint point = self.webView.scrollView.contentOffset;
      self.keyBoardPoint = point;
  }
  /// 鍵盤將要隱藏
  - (void)keyBoardHidden {
      self.webView.scrollView.contentOffset = self.keyBoardPoint;
  }
