Loading…

NSArray has a method containsObject: that you could use. Just pass it the image and it will tell you whether or not its in an array. Note, however, that it is comparing specific UIImages. You could have different UIImages that have the same source image. So passing it [UIImage imageNamed:@"asdfa"] will not work

It can work since imageNamed: caches the image, but only sometimes. So while it can work, you shouldn't use it because it's not guaranteed to work 100% of the time.
