Check Availability of UICollectionView

Availability Available in iOS 6.0 and later.

You can go with PSCollectionView

UICollectionView is not directly available in IOS5.

However there is a nice open source control for adding UICollectionView support in IOS5. Its called PSCollectionView and you can find it here: PSTCollectionView

It is a drop in library that emulates UICollectionView on IOS5 and passes through on IOS6. Very nice and works very well.

best of luck.

In fact the problem probably isn't due to UICollectionView not being available in iOS5. It looks as though you're using constraints in Interface Builder. It is that that's causing the problem.

So, two things:

Use something like PSTCollectionView to add UICollectionView support in iOS5
Switch off constraints and revert to using "springs and struts" to resize/relocate your subviews
