使用DeviceEventEmitter监听键盘调起事件手动控制view 高度避免键盘遮挡内容

[febobo]

  constructor (props){
    super(props);
    DeviceEventEmitter.addListener('keyboardWillShow', this.keyboardWillShow.bind(this));
    DeviceEventEmitter.addListener('keyboardWillHide', this.keyboardWillHide.bind(this));
  }

  keyboardWillShow (e){
    this.commentView && this.commentView.setNativeProps({
            style: {
                height: commentHeight - e.endCoordinates.height
            }
        })
  }

  keyboardWillHide (){
    this.commentView && this.commentView.setNativeProps({
            style: {
                height: commentHeight
            }
        })
  }  

 componentUnMount(){
    this.keyboardWillHideEvent.remove()
    this.keyboardWillShowEvent.remove()
  }
