I've two UIViewControllers. My first UIViewController shows various video thumbnails, photos and notes. And second controller is resposible for showing the selected video, photo or note in previous controller. I've also a UICollectionView in my first controller which lists everything just like Apple's Photo App in iOS.
I use "pushviewcontroller" to show my second view controller.
UIStoryboard *sb=[UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
FirstDetailViewController *fD=[sb instantiateViewControllerWithIdentifier:@"firstDetail"];
[self.navigationController pushViewController: seconVCObj animated: YES];
But I want to open it with a zoom effect like ios photo app. When you touch a photo, app shows the photo like zooming.
