YFCardTransitions is a set of custom UIViewController transitions designed to be used with Tim Gleue’s awesome TGLStackedViewController.

Installation

With CocoaPods, add this line to your Podfile.

pod 'YFCardTransitions'

Or drag the files inside the Source folder to your project

Example

Usage

First you have to subclass TGStackedViewController that conforms to UIViewControllerTransitioningDelegate and add two properties that will be responsible for the transitions:

@interface YFCardCollectionViewController () <UIViewControllerTransitioningDelegate>

@property (strong, nonatomic) YFCardPickTranstion           *cardPickTransition;
@property (strong, nonatomic) YFDragDownToDismissTransition *dragDownToDismissTransition;

@end

You have to set YFCardPickTransition duaration property to a desired value and cardTopReveal to the same value as TGLStackedLayout topReveal property


- (YFCardPickTranstion *)cardPickTransition {
    if (!_cardPickTransition) {
        _cardPickTransition = [YFCardPickTranstion new];
        _cardPickTransition.duration = 0.5;
        _cardPickTransition.cardTopReveal = self.stackedLayout.topReveal;
    }
    return _cardPickTransition;
}

Also create an UICollectionViewCell subclass to be used by you TGLStackedViewController subclass

In UICollectionViewDelegate protocol method collectionView:didSelectItemAtIndexPath: you should grab the selected cell reference frame and snapshot:

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {

    UICollectionViewLayoutAttributes *attributes = [collectionView layoutAttributesForItemAtIndexPath:indexPath];
    CGRect referenceFrame = [collectionView convertRect:attributes.frame toView:collectionView.superview];

    self.cardPickTransition.referenceFrame = referenceFrame;

    CardCollectionViewCell *cell = (CardCollectionViewCell *)[collectionView cellForItemAtIndexPath:indexPath];
    UIView *snapshotView = [cell snapshotViewAfterScreenUpdates:YES];

    self.cardPickTransition.movingCardSnapshot = snapshotView;

    self.selectedCardColor = cell.imageView.tintColor;

    [self performSegueWithIdentifier:@"showDetail" sender:nil];

}

Implement the UIViewControllerTransitioningDelegate methods :


- (id<UIViewControllerAnimatedTransitioning>)animationControllerForPresentedController:(UIViewController *)presented presentingController:(UIViewController *)presenting sourceController:(UIViewController *)source {

    return self.cardPickTransition;
}

- (id<UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController:(UIViewController *)dismissed {
    return  self.dragDownToDismissTransition;
}

- (id<UIViewControllerInteractiveTransitioning>)interactionControllerForDismissal:(id<UIViewControllerAnimatedTransitioning>)animator {

    return self.dragDownToDismissTransition;
}

Wire the presented view controller to the YFDragDownToDismissTransition instance :


- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    ViewController *vc = segue.destinationViewController;
    [self.dragDownToDismissTransition wireToViewController:vc];
    vc.transitioningDelegate = self;
    vc.modalPresentationStyle = UIModalPresentationCustom;
}

A complete working example is provided in this repository.
