Question

I want my program to be like this

if ([UIImageViewObject identifier]==@"heyItsMeYeaCoolDude")
{
    do some methods
}

Whenever I do this though my programs crashes saying:

2012-07-29 19:09:58.401 Bridges[2711:f803] -[UIImageView identifier]: unrecognized selector sent to instance 0x8874f70

With a bunch of crap after it.

In my storyboard, I typed heyItsMeYeaCoolDude under label in the identity inspector, and now my program is complaining.

I know I could use tags also, but I’m already using my images tag for something else, help!

In response to the suggestion you made in the comment below your question, @ownageGuy, an answer to the question you pose:

You’re welcome to subclass anything you like. Subclassing UIImageView is a perfectly acceptable solution to this problem. You might also consider the container pattern; ie. create a class which contains an instance of a UIImageView and an NSString for the identifier. Then even if there did happen to be a detriment to subclassing UIImageView, as you fear, it would be eliminated.

@interface UIImageViewContainer : NSObject
{
    UIImageView* imgView;
    NSString* identifier;
}

Then you create an object of type UIImageViewContainer, set imgView to the appropriate UIImageView, and store the identifier string inside identifier.
