模态跳转和导航push

使用模态跳转的动画push导航控制器：

//方法一：模态跳转，前提是利用navigationcontroller这个容器

//                UserManagerViewController *userManagerVC = [[UserManagerViewController alloc] init];

//                UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:userManagerVC];

//                [self presentViewController:nav animated:YES completion:nil];

//方法二：push，只不过有莫泰跳转的方式，这种方法更好

UserManagerViewController *userManagerVC = [[UserManagerViewController alloc] init];

CATransition *animation = [CATransition animation];

animation.duration = 0.2;

animation.type = kCATransitionMoveIn;

animation.subtype = kCATransitionFromTop;

animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault];

[self.navigationController.view.layer addAnimation:animation forKey:nil];

[self.navigationController pushViewController:userManagerVC animated:NO];//自定义动画，此处要设为NO
