Is there a way to get a collectionViews frame from a collectionviewcell

Question

I want to use

-preferredLayoutAttributesFittingAttributes inside the UICollectionviewCell subclass we are writing.

Currently we already had a weak pointer to out parentViewController and I try to set the collectionViewcell frame width to be the same as parentViewcontroller.view.frame.size.width.

I don't want to have a pointer to the parentViewController from the CollectionViewCell subclass as having a reference to the parentviewcontroller is a bad idea.

My question is....

Is there a simple and ideal way to get the frame of collectionviewcell's super view from inside the collectionViewcell class?

If you want to be use the parent view then you don't need any reference. You can do like this:

CGFloat width = self.superview.frame.size.width;

And as @Ralfonso pointed out in the comments:

Also, if you want to get the superview size immediately after being added to a view hierarchy, override didMoveToSuperview: and access the superview property. If it's nil, the view has been removed from the superview. If non-nil, the view has been added to the superview's hierarchy.
