本文详细介绍了如何在iOS应用中监听键盘高度变化，并动态调整布局以保持良好的用户体验。通过添加通知来实现键盘出现和消失时的布局自适应，确保应用在不同键盘高度下依然能正常工作。

一：添加通知监测键盘高度变化

[self keyBoardAutoSize];

二：动态改变高度

#pragma mark keyboard height auto
/*
 NSNotificationCenter：键盘出现、消失时的通知
 
 
 UIKeyboardWillShowNotification;
 UIKeyboardDidShowNotification;
 UIKeyboardWillHideNotification;
 UIKeyboardDidHideNotification;
 
 */

- (void) keyBoardAutoSize
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyBoardShow:) name:UIKeyboardWillShowNotification object:nil];

}


- (void)keyBoardShow:(NSNotification *) notif
{
    NSDictionary *info = [notif userInfo];
    NSValue *value = [info objectForKey:UIKeyboardFrameEndUserInfoKey];
    CGSize keyboardSize = [value CGRectValue].size;
    
    NSLog(@"keyBoard:%f", keyboardSize.height);  //216
        
    if (keyboardSize.height==216) {
        [UIView animateWithDuration:0.25 animations:^{
            bottomInput.top = kScreenHeight - 74 - keyboardSize.height;
        }];
    }
    //中文状态输入 252
    else if (keyboardSize.height== 252 )
    {
        [UIView animateWithDuration:0.1 animations:^{
            bottomInput.top = kScreenHeight - 74 - keyboardSize.height;
        }];
       
    }
    
 
}

三：移除通知

- (void)dealloc

{

[_hubTip release];

[[NSNotificationCenterdefaultCenter]removeObserver:selfname:UIKeyboardWillShowNotificationobject:nil];

[super dealloc];

}
