Doorway Transition https://github.com/mkftr/DoorwayTransition

Example Usage

All I wrote for this effect is "MFDoorwayTransition" class. You can apply this effect easily in between two views like below :

MFDoorwayTransition *transition = [[MFDoorwayTransition alloc] 
                                        initWithBaseView:self.view 
                                               firstView:self.currentView 
                                                lastView:self.nextView];
[transition buildAnimation];
[transition release];
