I need to create a certain number of UIImageViews based on the amount of objects inside of an NSMutableArray. For example, if there are 5 UIImage's inside of this NSMutableArray, how do I create 5 UIImageView's with those images?
Thanks

Use count property of NSArray:
UIImage *image1 = [UIImage imageNamed:@"img1.png"];
UIImage *image2 = [UIImage imageNamed:@"img2.png"];
UIImage *image3 = [UIImage imageNamed:@"img3.png"];
UIImage *image4 = [UIImage imageNamed:@"img4.png"];
UIImage *image5 = [UIImage imageNamed:@"img5.png"];
NSArray *imageArray = @[image1, image2, image3, image4, image5];
NSInteger imageCount = 0;
NSInteger imageViewYM = 20; // Ensure this is bigger than image height
for (UIImage *image in imageArray) {
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, imageViewYM * imageCount, image.size.width, image.size.height)];
imageView.image = image;
[self.view addSubview:imageView];
imageCount++;
}

Thanks, I have set it up now. Do you know if there is a way to have them move across for each imageView instead of overlapping? Thanks again

The NSInteger holds count of UIImageView which use based on the context like setting the superview' frame etc. However the for loop is good enough to let you access UIImages for you to create your image views.

@Dyllan - Sorry but I didn't quite get your question. Can you please rephrase.

since there are multiple UIImageViews being created, how can I space between them? At the moment it is working but they overlap, I was wondering how i would go about spacing between them. Thanks again

Glad it helped :). Could you please accept this answer.
Run a while loop for all the images and create a new UIImageView for each of them:
NSArray *imageArray = @[image1, image2, image3];
int i = 0;
while(i < imageArray.count) {
UIImageView * imageView = [[UIImageView alloc] init];
imageView.image = [imageArray objectAtIndex:i];
imageView.frame = CGRectMake(0, 0, 50, 50);
imageView.tag = i;
[self.view addSubview:imageView];
i++;
}
