You can create UIView which store UIImageView and change UIview background Color.

UIView *viewForImage = ....;
UIImageView *imageView = .....;
...

[viewForImage addSubview: imageView];
[self.view addSubview:viewForImage];
...

and then use for example

[viewForImage setBackgroundColor: [UIColor redColor]];
