How to push a UICollectionView programmatically?

Question

I am trying to push a UICollectionViewController when a button is pressed. I'm using this to push it:

RewardsCollectionViewController* rvc = [[RewardsCollectionViewController alloc] init];                 
[self.navigationController pushViewController:rvc animated:YES];

But when I tap on the button the app crashes and gives me this message: UICollectionView must be initialized with a non-nil layout parameter
In my RewardsCollectionViewController class I haven't done anything I just changed numberOfItemsInSection to 1.

There might me a possible solution here but I didn't find my answer on that page. As it is somehow related to UICollectionViewFlowLayout and I have no idea what that is.

Give the storyboard to your COllectionViewController after that change your code like this

 RewardsCollectionViewController* rvc = [self.storyboard instantiateViewControllerWithIdentifier:@"yourIdentifer"];                 
 [self.navigationController pushViewController:rvc animated:YES];

Hope this will help you
