如何装载Storyboard中的ViewController

Answer 1

　　

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：

　　[cpp] view plaincopyprint?

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

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

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

或者使用下面的代码：

　　[cpp] view plaincopyprint?

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

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

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

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