ios - 从 ViewController( Storyboard)调用 NavigationController (xib)

Question

我通常只为我的 iOS 使用 Storyboard，但需要集成一个不使用 Storyboard的 SDK，而是 xib。我的初始 View Controller 来自 Storyboard ，当按下按钮(IBAction)时，我希望它转到 xib View Controller ，但不确定如何以编程方式执行此操作。这是我的 AppDelegate:

 //AppDelegate.m

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:...{   

// set to storyboard on launch
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"iPhoneStoryboard"
                                                         bundle: nil];

UIViewController* viewController = [mainStoryboard instantiateInitialViewController];
[self.window setRootViewController:viewController];

 [window makeKeyAndVisible];
 return YES;
 }

这是我的代码.h:

 //mainVC.h
 #import <UIKit/UIKit.h>

 @interface MainVC : UIViewController{
 UIWindow *window;
 UINavigationController *navigationController;
 }

 @property (nonatomic, retain) IBOutlet UIWindow *window;
 @property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
 @property (nonatomic, retain) IBOutlet UIButton *buttonScan;

 -(IBAction) ActionScan;

 @end

还有.m:

 //mainVC.m
 @interface MainVC ()

 @end

 @implementation MainVC

 @synthesize window;
 @synthesize navigationController;
 @synthesize buttonScan;

 - (IBAction)ActionScan{

window.rootViewController = navigationController;
[window makeKeyAndVisible];

 }

使用 initWithNibName 创建 xib viewController 的实例

MyViewController *controller = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];

& 然后将这个 Controller 实例推送到导航 Controller 上

[self.navigationController pushViewController:desController animated:YES]
