用于多个图像的平滑UIImageView动画

Question

I have used animation on an UIImageView to animate 36 images like this:

-(void) kickOffTheAnimation {

    self.imgView.animationImages = imagesArr;

   [self.imgView setAnimationRepeatCount:HUGE_VALF];
   self.imgView.animationDuration =0.9;

    [self.imgView startAnimating];

}

and my viewDidLoad method is simply as:

NSMutableArray *imagesArr = [[NSMutableArray alloc] init];
for(int i =0; i<35; i++) {
    [imagesArr addObject:[UIImage imageNamed: [NSString stringWithFormat:@"img%i@2x.png",i]]];
 }

    [self kickOffTheAnimation];

However, there is a small glitch, the animation is not smooth when it reaches the final image and repeats the animation from the first image, how can I fix this problem?

EDIT:

the exact problem is there is a milliseconds hang happens after reaching img35.png and showing img0.png

Answer 1

I have sometimes noticed a very small loop delay with a larger in memory image array. It could be that some resource has to be reloaded. I have used AVPlayer in repeat mode with better luck for a small movie. An actual movie might also compress better.
