Any other way to do animations?

Question

Is there any other way to do animations besides my below code? I'm asking because I'm going to have some pretty intense animations that could get up to 20-30 frames. I'm also wondering if it's possible to play a sound with each frame?

popup.animationImages = [NSArray arrayWithObjects:
                                 [UIImage imageNamed:@"picture1.png"],
                                 [UIImage imageNamed:@"picture2.png"],
                                 [UIImage imageNamed:@"picture3.png"],
                                 [UIImage imageNamed:@"picture4.png"],
                                 [UIImage imageNamed:@"picture5.png"],
                                 [UIImage imageNamed:@"picture6.png"],
                                 [UIImage imageNamed:@"picture7.png"], nil];
        popup.animationDuration = 1.750567;
        popup.animationRepeatCount = 1;
        [popup startAnimating];
        [self.view addSubview:popup];

Well, short of something like

(NSArray *) createAnimationArrayWithFileStem:(NSString *) stem firstFrame:(int) firstFrame lastFrame:(int) lastFrame{
    NSMutableArray *animationArray = [[NSMutableArray alloc] init];
    for (int currentFrame=firstFrame;currentFrame<=lastFrame;currentFrame++){
        [animationArray addObject:[UIImage imageNamed:[NSString stringWithFormat:@"%@%d.png",stem,currentFrame]];
    }
    [animationArray addObject:nil];
    [animationArray autorelease];
    return animationArray;
}

Or something very much like that, would allow you to just do

popup.images = [self createAnimationArrayWithFileStem:@"picture" firstFrame:1 lastFrame:7];
