tableviewcell 里面的textview输入过程被遮挡问题

一，关于键盘弹起

• 判断点击所在的cell在屏幕上的位置是否被键盘遮挡
  cell所在位置可以通过以下两种方法获取

-(BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
    //tableview 偏移量
    _currentSrollowHeight=self.tvContent.contentOffset.y;
    NSLog(@"textFieldShouldBeginEditing---%f---:%f",_tvContent.contentOffset.y,_currentSrollowHeight);
    
    NSIndexPath *indexPath=[NSIndexPath indexPathForRow:textView.tag%100 inSection:textView.tag/100];
    CGRect rectInTableView = [self.tvContent rectForRowAtIndexPath:indexPath];
    
    CGRect rectInSuperView = [self.tvContent convertRect:rectInTableView toView:self.view];
    //点击cell位置
    _currentSelectTextfieldLocation = rectInSuperView.origin.y;
    //索引
    _selectTextfiedIndex=textView.tag;
    return YES;
}
- (void)keyboardWillShow:(NSNotification *)notification
{
    NSDictionary *userInfo = notification.userInfo;
    CGRect endFrame = [userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
    //计算出键盘顶端到inputTextView panel底端的距离(加上自定义的缓冲距离INTERVAL_KEYBOARD)
    // 取得键盘的动画时间，这样可以在视图上移的时候更连贯
    CGFloat offset;
    CGFloat theHeight;
   // _theRowHeighth cell高度
    theHeight=_currentSelectTextfieldLocation+_theRowHeight;

    
    offset=theHeight-(SCREEN_HEIGHT-endFrame.size.height);
    NSLog(@"endFrame.size.height---%f---%f---%f",endFrame.size.height,theHeight,offset);
    //将视图上移计算好的偏移
    if(offset > 0)
    {
        [self.tvContent setContentOffset:CGPointMake(0, offset+_currentSrollowHeight) animated:YES];
    }
    
}
- (void)keyboardWillHide:(NSNotification *)notification
{
    NSLog(@"_currentSrollowHeight---%f",_currentSrollowHeight);
    [self.tvContent setContentOffset:CGPointMake(0, _currentSrollowHeight) animated:YES];
}

键盘高度在通知方法里可以获取
