iOS-7-Custom-ModalViewController-Transitions

Sample project implementing new custom ModalViewController Transitions on iOS 7. We have a UIViewController view as a subview/modal on top of another UIViewController view, such as that the subview/modal should be transparent and whatever components are added to the subview should be visible. We decided not to use a segue in our Storyboard.

Requirements

Our sample requires iOS 7 and above.

Installation

• Add TransitionDelegate.h/m and AnimatedTransitioning.h/m to your project (4 files total). Or to drag a folder called Transition Delegate with files inside to your project.
• In your RootViewController.m file, include with #import "TransitionDelegate" and do the following to instantiate and to present a modal view controller with a clearColor in background.

#import "RootViewController.h"
#import "TransitionDelegate.h"

@interface RootViewController ()
@property (nonatomic, strong) TransitionDelegate *transitionController;
@end

@implementation RootViewController
@synthesize transitionController;

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view.
    self.transitionController = [[TransitionDelegate alloc] init];
}

- (IBAction)displaySecondVC:(id)sender {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"];
    vc.view.backgroundColor = [UIColor clearColor];
    [vc setTransitioningDelegate:transitionController];
    vc.modalPresentationStyle= UIModalPresentationCustom;
    [self presentViewController:vc animated:YES completion:nil];
}

@end

Usage

Check out the sample Xcode project in CustomTransitionExample.

Recommendations

This is outlined in the 'Custom Transitions Using View Controllers' talk from WWDC 2013, which also covers how to implement your own transition delegate.
