Usage

Basic usage

#import <UIKit/UIKit.h>

// You have to implement UIViewControllerTransitioningDelegate protocol
@interface ViewController : UIViewController<UIViewControllerTransitioningDelegate>
@end

#import "ViewController.h"

#import <JTMaterialTransition.h>
#import "SecondViewController.h"

@implementation ViewController

@interface ViewController ()

@property (nonatomic) JTMaterialTransition *transition;
@property (nonatomic) UIButton *presentControllerButton;

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    // No specific moment to call this method, just before presenting a controller
    [self createTransition];
}

- (void)didPresentControllerButtonTouch
{
    // The controller you want to present
    UIViewController *controller = [SecondViewController new];
    
    // Indicate you use a custom transition
    controller.modalPresentationStyle = UIModalPresentationCustom;
    controller.transitioningDelegate = self;

    [self presentViewController:controller animated:YES completion:nil];
}

// Initialize the tansition
- (void)createTransition
{
    // self.presentControllerButton is the animatedView used for the transition
    self.transition = [[JTMaterialTransition alloc] initWithAnimatedView:self.presentControllerButton];
}

// Indicate which transition to use when you this controller present a controller
- (id<UIViewControllerAnimatedTransitioning>)animationControllerForPresentedController:(UIViewController *)presented
                                                                  presentingController:(UIViewController *)presenting sourceController:(UIViewController *)source
{
    self.transition.reverse = NO;
    return self.transition;
}

// Indicate which transition to use when the presented controller is dismissed
- (id<UIViewControllerAnimatedTransitioning>)animationControllerForDismissedController:(UIViewController *)dismissed
{
    self.transition.reverse = YES;
    return self.transition;
}
@end

Notes

The animatedView is not directly used, a new view is created based on the frame, backgroundColor properties for the animation. If you don't want to provide a view, you have to set startFrame and startBackgroundColor properties and call init instead of initWithAnimatedView:.

Requirements
