UIKeyboardWillShowNotificationがiOS 7で動作しない

Question

UIKeyboardは、iOS8以降で正常に動作する通知方法を表示したり非表示にしたりしますが、iOS7では機能しません。何か別の選択肢はありますか？

マイアプリケーションの展開先はiOS7です。

マイコードは、ここで事前に

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

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(HideKeyboard:) 
               name:UIKeyboardWillHideNotification 
               object:nil]; 
} 

- (void)keyboardWasShown:(NSNotification *)sender 
{ 
    CGSize kbSize = 
     [[[sender userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size; 

    if (!scroll) { 
     scrollValue = self.WholeScreenUIView.frame.origin.y - kbSize.height; 
    } 

    scroll = YES; 
} 

- (void)HideKeyboard:(NSNotification *)sender 
{ 

    scroll = NO; 

    scrollValue = 0.0; 
} 

おかげです。

使用このコード..

[[NSNotificationCenter defaultCenter] addObserver:self 
               selector:@selector(keyboardWillHideHandler:) 
                name:UIKeyboardWillHideNotification 
                object:nil]; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(keyboardWillshowHandler:) 
               name:UIKeyboardWillShowNotification 
               object:nil]; 

- (void) keyboardWillHideHandler:(NSNotification *)notification { 
    [scroll setContentOffset:CGPointMake(0, 0) animated:YES]; 
} 

- (void) keyboardWillshowHandler:(NSNotification *)notification { 
    [scroll setContentSize:CGSizeMake(self.view.frame.size.width, self.view.frame.size.height+44)]; 

} 

希望このhelps.Thisは、私の場合で動作
