切换到ViewController（在故事板上）

我试图让我的应用程序从一个视图切换到另一个视图，然后有一个后退按钮。第一步我没有问题，但现在我正在尝试返回到我的主视图控制器。切换到ViewController（在故事板上）

我曾尝试这样的代码：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main.storyboard" bundle:nil]; 
ViewController *main = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"]; 
[main setModalPresentationStyle:UIModalPresentationFullScreen]; 
[self presentModalViewController:main animated:YES];

而且也：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main.storyboard" bundle:nil]; 
ViewController *mainView = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"]; 
[mainView setModalPresentationStyle:UIModalPresentationFullScreen]; 
[self presentViewController:mainView animated:YES completion:NULL];

但无论方法正常工作。用方法一，我在最后一行得到一个错误'presentModalViewController:animated:' is deprecated: first deprecated in iOS6.0 至于第二种方法，它只是简单的不起作用。

如果要备份按钮，而不是呈现视图控制器使用push方法，以便它会给你后退导航按钮自动

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

别人的故事板中添加的UIBarButtonItem在你的第二个视图控制器手动，并在该按钮目标方法调用

[self dismissViewControllerAnimated:YES completion:nil];
