Question

I have an array with UIImageView. Let’s say currently there’s 5 UIImageView in the array. How do I know which UIImageView i’m currently touching?

Thanks.

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
    UITouch *touch = [touches anyObject];

    if ([touch view] == ??)
    {

    }
}

One of most simple solution is to set tag properties of the views.

@property(nonatomic) NSInteger tag

This way you can easily retrieve the one touched :

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
    UITouch *touch = [touches anyObject];
    if ([[touch view] tag] == 1)
    {
        // ...
    }

}

You can set this property either in Interface Builder, or in code directly.
