MCCardPickerCollectionViewController

A card collection view controller inspired by Facebook People you may know.

Take a while for screenshot :p

Compatibility

Required on iOS 7.

Usage

Simply drag and drop the classes under /Classes folder and use it like normal collection view controller.

To initialize the MCCardPickerCollectionViewController

MCCardPickerCollectionViewController *cardViewController = [[MCCardPickerCollectionViewController alloc] init];
	cardViewController.delegate = self;
	//Don't forget to register cell like usual collection view.
	[cardViewController.collectionView registerClass:[MCSampleCardCollectionViewCell class] forCellWithReuseIdentifier:kCellIdentifier];

and implement the delegate:

- (void)cardPickerCollectionViewController:(MCCardPickerCollectionViewController *)cardPickerCollectionViewController preparePresentingView:(UIView *)presentingView fromSelectedCell:(UICollectionViewCell *)cell
{
    //Do whatever you want to prepare for the presenting view.
}

// and collection view delegate and data source

To present view controler, we use our own method to present instead of presentViewController:animated:completion: in order to keep the transparent background.

- (void)presentInViewController:(UIViewController *)viewController;

To dismiss view controller, likewise we use our own method:

- (void)dismissFromParentViewController;

Moreover there are some properties of MCCardPickerCollectionViewFlowLayout you can adjust. If you want to change the padding of cards, you can just set minimumLineSpacing:

cardViewController.layout.minimumLineSpacing = 40;

and the bouncing velocity of centering card by setting flickVelocity:

cardViewController.layout.flickVelocity = 0.5;

The current index means the card number user picked:

NSInteger currentIndex = cardViewController.layout.currentIndex;
