crash

[KatkayApps]

1. I create a view controller on storyboard
2. I assign that viewcontroller's class to BUKImagePickerController
3. I run the application. The camera roll item appears. I click on it. It crashes with this error:

the item width must be less than the width of the UICollectionView minus the section insets left and right values, minus the content insets left and right values.
The relevant UICollectionViewFlowLayout instance is <UICollectionViewFlowLayout: 0x7fe172d52e10>, and it is attached to <UICollectionView: 0x7fe17302b000; frame = (0 0; 414 736); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x7fe172c12220>; layer = <CALayer: 0x7fe172c17d10>; contentOffset: {0, 0}; contentSize: {0, 0}> collection view layout: <UICollectionViewFlowLayout: 0x7fe172d52e10>.

Hey, thank you for the report.

To be honest, BUKImagePickerController wasn't tested with NIB. It's my fault. However, I've been busy with my work these days. I will investigate it later and fix the bug as soon as possible.
