iOS12 - 使用WKWebView出现input键盘将页面上顶不下移

• 实际情况如下图

键盘弹起

• 解决办法：

  • 监听键盘的谈起和隐藏

  /// 监听将要弹起
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyBoardShow) name:UIKeyboardWillShowNotification object:nil];
  /// 监听将要隐藏
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyBoardHidden) name:UIKeyboardWillHideNotification object:nil];
  

  • 监听方法中设置WKWebView的scrollview的contentOffset

  /** 键盘谈起屏幕偏移量 */
  @property (nonatomic, assign) CGPoint keyBoardPoint;
  
  #pragma mark - addObserverKeyboard
  /// 键盘将要弹起
  - (void)keyBoardShow {
      CGPoint point = self.webView.scrollView.contentOffset;
      self.keyBoardPoint = point;
  }
  /// 键盘将要隐藏
  - (void)keyBoardHidden {
      self.webView.scrollView.contentOffset = self.keyBoardPoint;
  }
