Trying to create an animation of two images by switching images in a UIImageView
===

So, the code I use to set the image originally (it receives data from another iOS device over BlueTooth)

        UIImage *receivedImage = [UIImage imageWithData:data];
            if(receivedImage != nil)
            {
                NSLog(@"Image received is not nil.");
            }
            self.imageView.image = receivedImage;
            UIImageView *iv = [[UIImageView alloc] initWithImage:receivedImage];
            [self.view addSubview:iv];
            
            [self.photoAlbum addObject:receivedImage];


 works like a charm with setting the image.

However, when I try to add it to the NSMutableArray property "album," the image doesn't change.

  

      -(void)stereoscopicIterationA {
        self.imageView.image = nil;
        self.imageView.image = [self.photoAlbum objectAtIndex:1];
        NSTimer *theTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(stereoscopicIterationB) userInfo:nil repeats:NO];
        NSLog(@"Image 1");
        
    }
    
    -(void)stereoscopicIterationB {
        self.imageView.image = nil;
        self.imageView.image = [self.photoAlbum objectAtIndex:0];
        NSTimer *theTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(stereoscopicIterationA) userInfo:nil repeats:NO];
        NSLog(@"Image 0");
    }
    
    -(void)openAlbum:(id)sender
    {

        if([self.photoAlbum objectAtIndex:0] != nil && [self.photoAlbum objectAtIndex:1] == nil)
        {
        self.imageView.image = [self.photoAlbum objectAtIndex:0];
            
           
        [self dismissModalViewControllerAnimated:NO];
        }
        else if([self.photoAlbum objectAtIndex:0] !=nil && [self.photoAlbum objectAtIndex:1] !=nil ){
            //Set up NSTimer to swap self.imageView.image back and forth between 0 and 1 of photoAlbum.
            NSLog(@"Timer set up");
            NSTimer *theTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(stereoscopicIterationA) userInfo:nil repeats:YES];
            
        }

Any ideas?
