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`

```objc

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:

```objc

- (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. 

```objc

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

```

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

```objc

- (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`:

```objc

cardViewController.layout.minimumLineSpacing = 40;

```

and the bouncing velocity of centering card by setting `flickVelocity`:

```objc

cardViewController.layout.flickVelocity = 0.5;

```

The current index means the card number user picked:

```objc

NSInteger currentIndex = cardViewController.layout.currentIndex;

```
