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,但视图在横向模式下完全消失。处理这个问题有更优雅的解决方案吗?我阅读了apple keyboard management文档,但它没有提供很多方向问题。
答案 0 :(得分:3)
所以,我不幸的解决方案就是这个
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;
}
我想这是解决这个问题的唯一方法。我仍然喜欢优雅的解决方案:)
