barcontroller之后，点击评论弹出键盘，输入框被键盘遮盖，手动改变_inputView的 Y 值无效。不使用uitabbarcontroller没问题，使用uitabbarcontroller之后就出现遮盖问题

在CommentInputView.m里修改

#define InputViewHeightOffset 64      // the height of navigationBar

-(void) addNotify
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onKeyboardShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(onKeyboardHide:) name:UIKeyboardWillHideNotification object:nil];
}

-(void) removeNotify
{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];

}

-(void) onKeyboardShow:(NSNotification *) notify      // typo
{
    NSDictionary *info = notify.userInfo;
    CGRect frame = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
    _keyboardAnimationDuration = [[info objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
    _keyboardAnimationCurve = [[info objectForKey:UIKeyboardAnimationCurveUserInfoKey] integerValue];
    
    [self changeInputViewOffsetY:(frame.origin.y - InputViewHeight - InputViewHeightOffset)];
    
}

// change inputView when keyboard hide
- (void) onKeyboardHide:(NSNotification *) notify
{
    NSDictionary *info = notify.userInfo;
    CGRect frame = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
    _keyboardAnimationDuration = [[info objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
    _keyboardAnimationCurve = [[info objectForKey:UIKeyboardAnimationCurveUserInfoKey] integerValue];
    
    [self changeInputViewOffsetY:(frame.origin.y - InputViewHeight - InputViewHeightOffset) ];
}
