如上图所示，如何装载Storyboard中指定的ViewController?

首先，需要指定ViewController的ID，如上图右上方红色方框内的Storyboard ID。然后使用下面的代码：

UIStoryboard* mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];

LeftViewController *leftController = [mainStoryboard instantiateViewControllerWithIdentifier:@"leftViewController"];

或者使用下面的代码：

[cpp] view plain copy

UIStoryboard* mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];

ViewController *leftController = [mainStoryboard instantiateViewControllerWithIdentifier:@"leftViewController"];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:leftController];
