Question

我有一个顶部有一个工具栏的视图和一个带有文本字段的表格视图。当我想编辑放置在表格视图底部的文本字段时，键盘正在隐藏正在编辑的文本字段（因为表格视图不会向上滚动）。我试图实现http://cocoawithlove.com/2008/10/sliding-uitextfields-around-to-avoid.html，但这会使我的整个视图向上移动（工具栏和表视图），而我希望在整个视图的顶部都有toobar。我修改了上面提到的代码：

- (void)textFieldDidBeginEditing:(UITextField *)textField {

CGRect textFieldRect = [tableView.window convertRect:textField.bounds fromView:textField];
CGRect viewRect = [tableView.window convertRect:tmpTableView.bounds fromView:tableView];

CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height;
CGFloat numerator = midline - viewRect.origin.y - MINIMUM_SCROLL_FRACTION * viewRect.size.height;
CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION) * viewRect.size.height;
CGFloat heightFraction = numerator / denominator;

if (heightFraction < 0.0)  {
    heightFraction = 0.0;
} else if (heightFraction > 1.0) {
    heightFraction = 1.0;
}

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) {
    animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction);
} else  {
    animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction);
}

CGRect viewFrame = tableView.frame;
viewFrame.origin.y -= animatedDistance;

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];

[tableView setFrame:viewFrame];

[UIView commitAnimations];


}

和

- (void)textFieldDidEndEditing:(UITextField *)textField {
CGRect viewFrame = tableView.frame;
viewFrame.origin.y += animatedDistance;

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];

[tableView setFrame:viewFrame];

[UIView commitAnimations];
}

这使我的工具栏保持在顶部，但不幸的是，表格视图覆盖了工具栏，工具栏不可见。

任何想法如何解决这个问题？

不应重新定位表格视图，而应调整大小以使键盘不与其重叠。
