切換到ViewController（在故事板上）

我試圖讓我的應用程序從一個視圖切換到另一個視圖，然後有一個後退按鈕。第一步我沒有問題，但現在我正在嘗試返回到我的主視圖控制器。切換到ViewController（在故事板上）

我曾嘗試這樣的代碼：

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];

但無論方法正常工作。用方法一，我在最後一行得到一個錯誤'presentModalViewController:animated:' is deprecated: first deprecated in iOS6.0 至於第二種方法，它只是簡單的不起作用。

任何幫助深表感謝：我熱我的後退按鈕它崩潰，我可以儘快加載應用程序，但！

如果要備份按鈕，而不是呈現視圖控制器使用push方法，以便它會給你後退導航按鈕自動

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

別人的故事板中添加的UIBarButtonItem在你的第二個視圖控制器手動，並在該按鈕目標方法調用

[self dismissViewControllerAnimated:YES completion:nil];
