iOS开发给UInavigationController添加或者

    CATransition *transition = [CATransition animation];
    transition.duration = 1;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromRight;
    transition.delegate = self;
    self.navigationController.navigationBarHidden = NO;
    [self.navigationController.view.layer addAnimation:transition forKey:nil];
