Problem solved by adding animation manually

CATransition *transition = [CATransition animation]; 
transition.duration = 0.5; 
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]; 
transition.type = kCATransitionPush; 
transition.subtype = kCATransitionFromLeft; 
[self.navigationController.view.layer addAnimation:transition forKey:nil];
