在xcode

Question

目前我设计在用户按下键盘的返回按钮时在UITableView中添加新的行单元格。但问题是在添加4或5个uitableview单元格后，新单元格隐藏在键盘下。当按下返回键但是失败时，我正试图解决调整uitableview的问题。

以下是我的代码。

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{
    if ([text isEqualToString:@"\n"]) {

        CoachPadItem *newCoachPadItem = [[CoachPadItem alloc]init];
        newCoachPadItem.coachpadDescription = @"NULL";
        newCoachPadItem.coachpadTagId = @"0";
        [_tagPointsArray addObject:newCoachPadItem];
        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[_tagPointsArray count]-1 inSection:0];
        [_coachpadTableView beginUpdates];

        CoachPadPointCell *cell = (CoachPadPointCell*)[_coachpadTableView cellForRowAtIndexPath:0];
        [cell.txtPoint becomeFirstResponder];

        isType = TRUE;
        if ([isDelete isEqualToString:@"1"]) {
            isDelete = @"2";
        }

        [_coachpadTableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
        [_coachpadTableView endUpdates];

        return NO;
    }
    return YES;
}

添加4-5细胞后，执行以下操作：

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.3];
[UIView setAnimationBeginsFromCurrentState:YES];

CGRect frame = self.view.frame;
frame.origin.y = - 170;
self.view.frame = frame;

[UIView commitAnimations];

输入完成后

再次将y设置为0
