调整查看

我有一张桌子,下面是他们的底视图。我的目标是在键盘输出时向上移动。但是当我们调整键盘时,这种方法会向上调用我的底部视图。我被困了

- (void)keyboardWasShown:(NSNotification*)aNotification
{    
        NSDictionary* info = [aNotification userInfo];
        CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    keyBoadSize =kbSize.height;

        [UIView animateWithDuration:0.2f animations:^{
        CGRect frame=bottomView.frame;
        keyBoardHeight = keyBoadSize;


        frame.origin.y -=keyBoadSize;
          bottomView.frame=frame;
        frame = tableViews.frame;
        frame.size.height -= keyBoardHeight;
        tableViews.frame = frame;



}

我也在使用

- (void)textViewDidChange:(UITextView *)textView
{
    CGFloat fixedWidth = textView.frame.size.width;
    CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
    CGRect newFrame = textView.frame;
    newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
    textView.frame = newFrame;
    CGRect frame1 = [UIScreen mainScreen].bounds;
    bottomView.frame=CGRectMake(0, frame1.size.height-keyBoardHeight-20-newSize.height, self.view.frame.size.width, newSize.height+50);



}

答案 0 :(得分:0)

您需要先在表格视图中添加空格以允许滚动:

[self.tableView setContentInset:UIEdgeInsetsMake(0.0, 0.0, keyBoardheight, 0.0)];

然后设置自定义底部视图的Y位置。

作为旁注,您的示例代码keyBoadSize具有误导性。它应该是keyBoardheight

PS:当键盘解除时,不要忘记重置滚动空间:[self.tableView setContentInset:UIEdgeInsetsZero];
