Seems you are trying to create the UIImageView from images that are located in your resources (but they are not there!).

[imageView setImage: [UIImage imageNamed:[NSString stringWithFormat:@"%d.png", i]]];

whats the point of placing the images in a array, if you dont use it?

try this instead:

[imageView setImage: [images objectAtIndex:i]];
