CCModalTransition

Extensible & easy to use modal transitioning using UIViewControllerAnimatedTransitioning API

##Installation

There are two ways to use the library in your project:

Manually add the library files to your project
Using CocoaPods (this is not yet possible but will be)

pod 'CCModalTransition'

Import UIViewController+ModalTransition.h file in your project, .pch file is a good place if you want it to be available in all your projects.

##Usage

In the initializer of the view controller to be displayed modally, configure the modal transition style using a registered ModalTransitionType.

#pragma mark - Constructor
- (id)init
{
    if (self = [super initWithNibName:@"PopupViewController" bundle:nil])
    {
        /**
         * Here, you just need to use a CCModalTransition type
         * to be used when the view controller is displayed 
         * modally
         */
        self.modalTransitionStyle = ModalTransitionTypePopup;
    }
    
    return self;
}

Built-in types are :

ModalTransitionTypePopup
ModalTransitionTypeTopSliding

You can extend this list by registering new transition types (see "Register your own transition types" section)

##Register your own transition types You can easily create custom transition types to extends this component capabilities in your project. To do that, you will need to create a new class extending CCModalTransition and implement the following methods :

- (NSTimeInterval)transitionDuration:(id<UIViewControllerContextTransitioning>)transitionContext;
- (void)presentViewControllerWithContext:(id <UIViewControllerContextTransitioning>)transitionContext animated:(BOOL)animated;
- (void)dismissViewControllerWithContext:(id <UIViewControllerContextTransitioning>)transitionContext animated:(BOOL)animated;

Do not forget to declare an unique, integer typed, identifier, for instance using a macro:

#define MyCustomModalTransitionIdentifier   54321

You can then register the transition by using UIViewController+ModalTransition methods :

- (void)registerClass:(Class)transitionClass forTransitionType:(NSInteger)transitionType;
- (void)unregisterClassForTransitionType:(NSInteger)transitionType;

For example, in your presenting view controller (not presented!):

// Register transition
[self registerClass:[MyCustomModalTransition class] forType:MyCustomModalTransitionIdentifier];

The declared transitionType should be used when declaring modal transition style of your presented view controller:

self.modalTransitionStyle = MyCustomModalTransitionIdentifier;

##Note about landscape transitions

As part of iOS7, interface transitions in landscape orientation are not properly working. Workarounds exist (read this article for more details: http://www.brightec.co.uk/blog/ios-7-custom-view-controller-transitions-and-rotation-making-it-all-work) and should be handled directly by CCModalTransition subclasses.
