I know its been 3 months Im writing this because i had the same issue and I'm just now finding out about it....the first 9 images have 4 zeros (CB00001). the rest have 3 (CB00010)

If you are seeing a jerk in the animation then I address the issue after 10.40 in the video.

Yes, I had already replaced the starting image with CB00001. My animation doesn't just have a quirk at the beginning though, the entire sequence is VERY choppy. When I changed the FPS from 2.5f to 1, I saw a change, which led me to believe it's a framerate issue, but it still isn't as smooth as the animation you have in the video at all.

I did in fact miss one of the images, so I changed that. The animation still isn't smooth though. I can't figure out what else in the code would affect it.

Here's the code from the ViewController below:

• (void)viewDidLoad { [super viewDidLoad]; self.crystalBall = [[MMCrystalBall alloc] init]; self.backgroundImageView.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"CB00001"], [UIImage imageNamed:@"CB00002"], [UIImage imageNamed:@"CB00003"], [UIImage imageNamed:@"CB00004"], [UIImage imageNamed:@"CB00005"], [UIImage imageNamed:@"CB00006"], [UIImage imageNamed:@"CB00007"], [UIImage imageNamed:@"CB00008"], [UIImage imageNamed:@"CB00009"], [UIImage imageNamed:@"CB00010"], [UIImage imageNamed:@"CB00011"], [UIImage imageNamed:@"CB00012"], [UIImage imageNamed:@"CB00013"], [UIImage imageNamed:@"C000014"], [UIImage imageNamed:@"CB00015"], [UIImage imageNamed:@"CB00016"], [UIImage imageNamed:@"CB00017"], [UIImage imageNamed:@"CB00018"], [UIImage imageNamed:@"CB00019"], [UIImage imageNamed:@"CB00020"], [UIImage imageNamed:@"CB00021"], [UIImage imageNamed:@"CB00022"], [UIImage imageNamed:@"CB00023"], [UIImage imageNamed:@"CB00024"], [UIImage imageNamed:@"CB00025"], [UIImage imageNamed:@"CB00026"], [UIImage imageNamed:@"CB00027"], [UIImage imageNamed:@"CB00028"], [UIImage imageNamed:@"CB00029"], [UIImage imageNamed:@"CB00030"], [UIImage imageNamed:@"CB00031"], [UIImage imageNamed:@"CB00032"], [UIImage imageNamed:@"CB00033"], [UIImage imageNamed:@"CB00034"], [UIImage imageNamed:@"CB00035"], [UIImage imageNamed:@"CB00036"], [UIImage imageNamed:@"CB00037"], [UIImage imageNamed:@"CB00038"], [UIImage imageNamed:@"CB00039"], [UIImage imageNamed:@"CB00040"], [UIImage imageNamed:@"CB00041"], [UIImage imageNamed:@"CB00042"], [UIImage imageNamed:@"CB00043"], [UIImage imageNamed:@"CB00044"], [UIImage imageNamed:@"CB00045"], [UIImage imageNamed:@"CB00046"], [UIImage imageNamed:@"CB00047"], [UIImage imageNamed:@"CB00048"], [UIImage imageNamed:@"CB00049"], [UIImage imageNamed:@"CB00050"], [UIImage imageNamed:@"CB00051"], [UIImage imageNamed:@"CB00052"], [UIImage imageNamed:@"CB00053"], [UIImage imageNamed:@"CB00054"], [UIImage imageNamed:@"CB00055"], [UIImage imageNamed:@"CB00056"], [UIImage imageNamed:@"CB00057"], [UIImage imageNamed:@"CB00058"], [UIImage imageNamed:@"CB00059"], [UIImage imageNamed:@"CB00060"],nil]; self.backgroundImageView.animationDuration = 2.5f; self.backgroundImageView.animationRepeatCount = 1; }

• (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; }

pragma mark - Prediction

• (void) makePrediction { [self.backgroundImageView startAnimating]; self.predictionLabel.text = [self.crystalBall randomPrediction]; }

pragma mark - Motion Events

• (void) motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { self.predictionLabel.text = nil; }

• (void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event { if ( motion == UIEventSubtypeMotionShake ){ [self makePrediction]; } }

-(void) motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event { NSLog(@"motion cancelled"); }

pragma mark - Touch Events

• (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { self.predictionLabel.text = nil; }

• (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [self makePrediction]; }

• (void) touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touches cancelled"); }

@end

and it worked for me
