Adding a UIButton to a UICollectionView cell programmatically

Question

I have a UIViewController with a UICollectionView created inside it programmatically. I want to add a button to the cell:

viewDidLoad:

Answer 1

Add your button as a subview of cell.contentView. Also, don't create the button every time collectionView:cellForItemAtIndexPath: is called. You might be reusing an existing cell that already has a button. Better to add the button in your custom cell's init method instead. Then just hide the button when you don't need it.
