I have been having issues compiling my app since I added animations. I am not too sure what is going on, but there is a green highlight on the line stated above which is right about here I implement my animation and images. Please help. Am I doing something wrong? I think this is the only error I have so far.

import "THViewController.h"

import "THCrystalBall.h"

import <AudioToolbox/AudioToolbox.h>

@interface THViewController ()

@end

@implementation THViewController { SystemSoundID soundEffect; }

• (void)viewDidLoad { [super viewDidLoad];

  NSString *soundPath = [[NSBundle mainBundle]pathForResource:@"crystal_ball" ofType:@"mp3"]; NSURL *soundURL = [NSURL fileURLWithPath:soundPath]; AudioServicesCreateSystemSoundID(CFBridgingRetain(soundURL), &soundEffect);

  self.crystalBall = [[THCrystalBall alloc] init]; self.backgroundImageView.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"CB00001"], [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:@"CB00014"], [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;

Here is what it says in the debugging console
