Question

When i am Building this code i am getting WARNING that INVALID Integer to pointer conversion.
But when I run the application it gets Crash …..

can any one help me… I am getting warning at withObject:[sender tag]

i have frontButtonScaleUp Method which takes (NSIngeter) argument… and also tag returns NSInteger value…

- (IBAction)frontButtonReleased:(id)sender
{
    const double delay = 0.3;
    double elapsed = CACurrentMediaTime() - tapStartTime;;
    if (elapsed >= delay)
        [self frontButtonScaleUp:[sender tag]];
    else
        [self performSelector:@selector(frontButtonScaleUp) withObject:[sender tag] afterDelay:delay - elapsed];
}

Answer 1

I have made work my code with little modifications like below:

- (IBAction)frontButtonReleased:(id)sender
{
    const double delay = 0.4;
    double elapsed = CACurrentMediaTime() - tapStartTime;;
    UIButton *btn = (UIButton *)sender;

    if (isBtnOneTurnOver || isBtnTwoTurnOver)
    {
        if ([btn tag] == 1)
        {
            if (elapsed >= delay)
                [self btnOneScaleUp];
            else
                [self performSelector:@selector(btnOneScaleUp) withObject:nil afterDelay:(delay - elapsed)];
        }
        else
        {
            if (elapsed >= delay)
                [self btnTwoScaleUp];
            else
                [self performSelector:@selector(btnTwoScaleUp) withObject:nil afterDelay:(delay - elapsed)];
        }
    }
}

here i have made two new methods for each button and both having no arguments so… that the problem of passing withObject was solved….
