키패드 따라 움직이는 textField

 

1.  textField클릭시 처리
    :view를 하나 만들어서 올리는거처럼 보이게 한다.

- (void)keyboardWillShow:(NSNotification *)notice

{

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0.3];

    CGRect rect = self.view.frame;

    rect.origin.y -= 215;

    rect.size.height += 215;

    self.view.frame = rect;

    [UIView commitAnimations];

} 

2. 리턴 버튼 클릭시 처리
    :만들어진 view의 y좌표를 조절하여 내리는거처럼 보이게 한다.

- (BOOL)textFieldShouldReturn:(UITextField *)textField{

    [textField resignFirstResponder];

    

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0.3];

    CGRect rect = self.view.frame;

    rect.origin.y += 215;

    rect.size.height -= 215;

    self.view.frame = rect;

    [UIView commitAnimations];

    

    return YES;

} 

- (void)viewWillAppear:(BOOL)animated{

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:self.view.window];

}

- (void)viewWillDisappear:(BOOL)animated{

    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];

}
