Accessing image with a tag in UIImageview

Question

I'm trying to compare two images that is stored as an array of UIImageView.

How can I access a particular image through a tag?

EDIT: If images were stored as separate UIImageView I would have compared

imageView1.image == imageView2.image;

But since it is stored as an array I'm confused to access it. Ideally it would be

someArray[1].image == someArray[2].image;

But it is not viable.

Are you saying that you want to access it through the tag you set or you are talking about the index of an array? — Lucas Huang, Jan 17 '15 at 22:10
Whatever applicable. I just wanted to get an access to an image — JannaBotna, Jan 19 '15 at 04:26

UIImageView *imageView = (UIImageView*)[self.view viewWithTag:someTag];

Just send viewWithTag to any instance of UIView and you'll get the View with that tag back.

Point of clarification: Not any UIView, but any superview of the view in question. (or super-super view, etc.) It won't work if the UIView you query is a sibling of your image view. – Duncan C Jan 17 '15 at 22:11
David, remember that lots of total newbies read SO. You shouldn't make any statements that can be misinterpreted due to a lack of prior knowledge. Even if the OP gets it, the 50 other newbies who read the thread won't. – Duncan C Jan 17 '15 at 23:59
I'm Not knocking newbies either. We were all beginners once. (Of course there was no such thing as the internet when I was a newbie, but that's a different story.) – Duncan C Jan 18 '15 at 00:00
