        default:
            break;

    }

}

[self performSelector:@selector(animateTransition:) withObject:[NSNumber numberWithFloat: TIME_FOR_EXPANDING]];
}

//animate Transition

-(void)animateTransition:(NSNumber *)duration {

self.view.userInteractionEnabled=NO;
[[self view] addSubview:viewController.view];
if ((viewController.view.hidden==false) && ([duration floatValue]==TIME_FOR_EXPANDING)) {
    viewController.view.frame=[[UIScreen mainScreen] bounds];
      viewController.view.transform=CGAffineTransformMakeScale(SCALED_DOWN_AMOUNT, SCALED_DOWN_AMOUNT);
}
viewController.view.hidden=false;
if ([duration floatValue]==TIME_FOR_SHRINKING) {
    [UIView beginAnimations:@"animationShrink" context:NULL];
    [UIView setAnimationDuration:[duration floatValue]];
    viewController.view.transform=CGAffineTransformMakeScale(SCALED_DOWN_AMOUNT, SCALED_DOWN_AMOUNT);
}
else {
        [UIView beginAnimations:@"animationExpand" context:NULL];

        [UIView setAnimationDuration:[duration floatValue]];
        viewController.view.transform=CGAffineTransformMakeScale(1, 1);
}
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
[UIView commitAnimations];
 }

//animated stop

   -(void)animationDidStop:(NSString *)animationID finished:(BOOL)finished context:(void *)context{

self.view.userInteractionEnabled=YES;

if ([animationID isEqualToString:@"animationExpand"]) {

    UINavigationController *navig = [[[UINavigationController alloc] initWithRootViewController:viewController] autorelease];

    [self presentModalViewController:navig animated:NO];
}
else {
    viewController.view.hidden=true;
}
}

its work as per my require Thanks

On action...take a image View add it as subview to your view,load with series of images of explosion(or any thing which you want) start it animating, when the animation finishes from the delegate remove it from superview.
