键盘、方向和 UITextView

我有一个覆盖整个屏幕的 UITextview。为了补偿键盘，我添加了这个处理程序：

- (void)keyboardWasShown:(NSNotification*)aNotification{
    // Resize for the stupid keyboard
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    CGRect rect = _textView.frame;
    rect.size.height -= kbSize.height;
    _textView.frame = rect;

    CGPoint p = [_textView contentOffset];
    [_textView setContentOffset:p animated:NO];
    [_textView scrollRangeToVisible:NSMakeRange([_textView.text length], 0)];
}

这在纵向模式下工作得很好，但在横向模式下视图完全消失。有没有更优雅的解决方案来处理这个问题？我阅读了苹果键盘管理文档，但它对于方向问题没有提供太多帮助。

I've got a UITextview that covers the entire screen. To compensate for the keyboard I added this handler:

- (void)keyboardWasShown:(NSNotification*)aNotification{
    // Resize for the stupid keyboard
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    CGRect rect = _textView.frame;
    rect.size.height -= kbSize.height;
    _textView.frame = rect;

    CGPoint p = [_textView contentOffset];
    [_textView setContentOffset:p animated:NO];
    [_textView scrollRangeToVisible:NSMakeRange([_textView.text length], 0)];
}

This works dandy in portrait mode, but the view completely disapears in landscape mode. Is there a more elegant solution for dealing with this? I read apples keyboard management documentation, but it doesn't have much to offer for orientation issues.

所以，我不幸的解决方案是

UIInterfaceOrientation o = [self interfaceOrientation];
if(o == UIInterfaceOrientationPortrait || o == UIInterfaceOrientationPortraitUpsideDown){
    rect.size.height -= kbSize.height;
}else if(o == UIInterfaceOrientationLandscapeLeft || o == UIInterfaceOrientationLandscapeRight){
    rect.size.height -= kbSize.width;
}

我认为这是解决这个问题的唯一方法。不过，我仍然喜欢一个优雅的解决方案:)

So, my unfortunate solution is this

UIInterfaceOrientation o = [self interfaceOrientation];
if(o == UIInterfaceOrientationPortrait || o == UIInterfaceOrientationPortraitUpsideDown){
    rect.size.height -= kbSize.height;
}else if(o == UIInterfaceOrientationLandscapeLeft || o == UIInterfaceOrientationLandscapeRight){
    rect.size.height -= kbSize.width;
}

Which i suppose is the only way to address this. I'd still love an elegant solution though :)
