Defining a group of objects

Is there anyway to group objects?

Say for example I have UIImageView1, UIImageView2, and UIImageView3 and I want to hide them all... do I have to type EVERY TIME

UIImageView1.hidden = YES;
UIImageView2.hidden = YES;
UIImageView3.hidden = YES;

Or is there anyway that I can define a group and just say group1.hidden = YES;

you must add 3 imageView to a parentView and then

foreach (UIView *view in parentView.subViews) {

if([view isMemberOf:[UIImageView class]])

{

    [view setHidden:YES];

} }

by other way you can add tag for each imageView above and get it to setHidden

You could use Key-Value Coding:

NSArray *imageViews = @[imageView1, imageView2, imageView3];
[imageViews setValue:@YES forKey:@"hidden"];

This works because calling setValue:forKey: on an NSArray invokes setValue:forKey: on each of the array's items.
