Crystal ball app only moving with Animation when you shake it. I have no idea why?

Question

Here is the video  http://teamtreehouse.com/library/build-a-simple-iphone-app-ios7-2/animating-and-intercepting-events/image-based-animation  
//and here is my code 
import "THViewController.h"
import "THCrystalBall.h"
@interface THViewController ()
@end
@implementation THViewController
(void)viewDidLoad
{
[super viewDidLoad];
self.crystalBall = [[THCrystalBall alloc] init];
self.backgroundImageView.animationImages = [[NSArray alloc] initWithObjects:
                                            [UIImage imageNamed:@"CB00001"],
                                            [UIImage imageNamed:@"CB00002"],
                                            [UIImage imageNamed:@"CB00003"],
                                            [UIImage imageNamed:@"CB00004"],
                                            [UIImage imageNamed:@"CB00005"],
//alot of typing ....im going to skip down... 
                                            [UIImage imageNamed:@"CB00059"],
                                            [UIImage imageNamed:@"CB00060"],nil];

self.backgroundImageView.animationDuration = 2.5f;
self.backgroundImageView.animationRepeatCount = 1;
}
(void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
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");
}

so are you saying its not animating when you tap the screen? if so can you post your code for the touches please. you need to make sure you call the makePrediction method inside the touches ended method:
```
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
[self makePrediction];
}
```
