CATransition *transition = [CATransition animation];

    transition.duration = 0.5f;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

    transition.subtype = kCATransitionFromLeft;
    transition.delegate = self;
    [self.navigationController.view.layer addAnimation:transition forKey:nil];
    MainViewController * fc = [[MainViewController alloc]init];
    fc.view.backgroundColor = [UIColor whiteColor];
    [self.navigationController pushViewController:fc animated:NO];
