用Storyboard 来创建Controller之间的跳转,但是有时候,想用代码来控制跳转,如何获取ViewController,这个和我们一般创建视图控制器的方法不一样.

UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];

 FirstViewController *firstCtrl = [story instantiateViewControllerWithIdentifier:@"firstViewController"];

[self.navigationController pushViewController:firstCtrl animated:YES];
