iphone frame by frame animation memory issues.

Question

I have a frame by frame animation but it is causing my iPad to crash. There are actually a few animations, located in different view controllers, and they work but after a while of switching between them it will crash the app. I think it could be a memory issue that I need to release name, image and array after the animation, but how do I do that?

-(void)viewDidLoad{
        NSMutableArray *array = [NSMutableArray arrayWithCapacity:35];
        for (int i = 0; i < 35; ++i) {
            NSString *name = [NSString stringWithFormat:@"ivf1_000%d.png",i];
            UIImage *image = [UIImage imageNamed:name];
            [array addObject:image];
        }
        graphanimation.animationImages = array;
        graphanimation.animationDuration = 2;
        graphanimation.animationRepeatCount = 1;
        [graphanimation startAnimating];
        [super viewDidLoad];    
    }
