如何裝載Storyboard中的ViewController？

 

如上圖所示，如何裝載Storyboard中指定的ViewController?

首先，須要指定ViewController的ID，如上圖右上方紅色方框內的Storyboard ID。而後使用下面的代碼：

 

 

UIStoryboard* mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
LeftViewController *leftController = [mainStoryboard instantiateViewControllerWithIdentifier:@"leftViewController"];

或者使用下面的代碼：

 

 

UIStoryboard* mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
ViewController *leftController = [mainStoryboard instantiateViewControllerWithIdentifier:@"leftViewController"];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:leftController];
