dismissModalViewController with transition: left to right


I was using a nice method to dismiss my modal view controller:

[self dismissModalViewControllerWithTransition:2];

which makes a slide transition from left to right, like a navigation controller does to pop a view.

As this method is a non-public method, apple will not accept it. How can I program this kind of animation in my code (slide from left to right, to dismiss a modal view, and slide from right to left to present a modal view) ?

Thanks in advance


Solution

  • I have accepted the answer from Safecase, but I would like to publish my final solution here:

    1) To present a modal view controller with a from right to left transition I have written following method:

    -(void) presentModalView:(UIViewController *)controller {
        CATransition *transition = [CATransition animation];
        transition.duration = 0.35;
        transition.timingFunction =
        [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
        transition.type = kCATransitionMoveIn;
        transition.subtype = kCATransitionFromRight;
    
        // NSLog(@"%s: self.view.window=%@", _func_, self.view.window);
        UIView *containerView = self.view.window;
        [containerView.layer addAnimation:transition forKey:nil];
        [self presentModalViewController:controller animated:NO];
    }
    

    2) To dismiss a modal view with an slide transition left to right:

    -(void) dismissMe {
        CATransition *transition = [CATransition animation];
        transition.duration = 0.35;
        transition.timingFunction =
        [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
        transition.type = kCATransitionMoveIn;
        transition.subtype = kCATransitionFromLeft;
    
        // NSLog(@"%s: controller.view.window=%@", _func_, controller.view.window);
        UIView *containerView = self.view.window;
        [containerView.layer addAnimation:transition forKey:nil];
    
        [self dismissModalViewControllerAnimated:NO];
    }
    

    Thanks guys!
