Move UIView up when keyboard appears

Ok so I have gone through almost all questions on SO and tutorials. I am now able to move my UIView up so that it is visible while typing. However the problem is, I want to move the UIView ONLY if the UITextField gets covered by the keyboard, because if it is not, then there is no point in moving the UIView. My code so far:

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

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

#pragma mark - keyboard movements
- (void)keyboardWillShow:(NSNotification *)notification
{
    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    [UIView animateWithDuration:0.3 animations:^{
        CGRect f = self.view.frame;
        f.origin.y = -keyboardSize.height;
        self.view.frame = f;
    }];
}

-(void)keyboardWillHide:(NSNotification *)notification
{
    [UIView animateWithDuration:0.3 animations:^{
        CGRect f = self.view.frame;
        f.origin.y = 0.0f;
        self.view.frame = f;
    }];
}

Any help will be appreciated, thank you.

To check is UITextField covered by keyboard you can do something like this:

- (void)keyboardWillShow:(NSNotification *)notification {
    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    if (myTextField.frame.origin.y + myTextField.frame.size.height > [UIScreen mainScreen].bounds.size.height - keyboardSize.height) {
        // textfield is covered by keyboard
        [UIView animateWithDuration:0.3 animations:^{
            CGRect f = self.view.frame;
            f.origin.y = -keyboardSize.height;
            self.view.frame = f;
        }];
    }
}
