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];
