keyboardWillShow

Question

Burada, programımı hata ayıkladığımda, her zaman klavyeWillShow işlevinin yanıt vermediğini gördüm. sadece ilk kez, program tarafından çağrılacak. İşte benim kodum, kodumda neyin yanlış olduğunu bilmiyorum, fakat klavye ilk görüntülendiğinde, işlev iyi çalışıyor.

- (void)keyboardWillShow:(NSNotification *)notification { 

    /* 
    Reduce the size of the text view so that it's not obscured by the keyboard. 
    Animate the resize so that it's in sync with the appearance of the keyboard. 
    */ 


    NSDictionary *userInfo = [notification userInfo]; 

    // Get the origin of the keyboard when it's displayed. 
    NSValue* aValue = [userInfo objectForKey:UIKeyboardFrameEndUserInfoKey]; 

    // Get the top of the keyboard as the y coordinate of its origin in self's view's coordinate system. The bottom of the text view's frame should align with the top of the keyboard's final position. 
    CGRect keyboardRect = [aValue CGRectValue]; 
    keyboardRect = [self.view convertRect:keyboardRect fromView:nil]; 

    CGFloat keyboardTop = keyboardRect.origin.y; 
    CGRect newTextViewFrame = self.textview.frame; 

    newTextViewFrame.size.height = keyboardTop - self.view.bounds.origin.y; 

    // Get the duration of the animation. 
    NSValue *animationDurationValue = [userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey]; 
    NSTimeInterval animationDuration; 
    [animationDurationValue getValue:&animationDuration]; 

    // Animate the resize of the text view's frame in sync with the keyboard's appearance. 
    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration:animationDuration]; 

    textview.frame = newTextViewFrame; 

    [UIView commitAnimations]; 
} 
- (void)keyboardWillHide:(NSNotification *)notification { 

    NSDictionary* userInfo = [notification userInfo]; 

    /* 
    Restore the size of the text view (fill self's view). 
    Animate the resize so that it's in sync with the disappearance of the keyboard. 
    */ 
    NSValue *animationDurationValue = [userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey]; 
    NSTimeInterval animationDuration; 
    [animationDurationValue getValue:&animationDuration]; 

    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration:animationDuration]; 

// textview.frame = self.view.bounds; 
    [self save]; 

    [UIView commitAnimations]; 
}

}
