Could not find a storyboard named 'Main' in bundle NSBundle ios 新建项目删除Main.storyboard报错

废话少说 直接流程

1. 删除Main.storyboard

2. iOS13引入了分屏，在SceneDelegate.m中添加代码

如果项目不使用分屏也按这个步骤继续往下走

- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions {
    if (scene) {
        UIWindowScene *windowScene = (UIWindowScene *)scene;
        self.window = [[UIWindow alloc]initWithWindowScene:windowScene];
        ViewController *vc =[[ViewController alloc]init];
        vc.view.backgroundColor = [UIColor whiteColor];//如果不设置背景颜色，屏幕一会就会自动变黑，有知道原因的请赐教
        self.window.rootViewController = vc;
        [self.window makeKeyAndVisible];
    }
}

3. 删除info.plist下的Storyboard Name

4. 删除TARGETS下Deployment info下的Main interface的main

5. clear工程 重新运行

这样就可以了。如果项目没有分屏不用SceneDelegate，那就继续往下步骤走

5. AppDelegate更改

AppDelegate.h添加window属性

@property (strong, nonatomic) UIWindow * window;

AppDelegate.m添加如下代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    ViewController *vc =[[ViewController alloc]init];
    vc.view.backgroundColor = [UIColor whiteColor];
    self.window.rootViewController = vc;
    [self.window makeKeyAndVisible];
    return YES;
}

同时删除下面的UISceneSession lifecycle方法

- (UISceneConfiguration *)application:(UIApplication *)application configurationForConnectingSceneSession:(UISceneSession *)connectingSceneSession options:(UISceneConnectionOptions *)options {
    // Called when a new scene session is being created.
    // Use this method to select a configuration to create the new scene with.
    **return** [[UISceneConfiguration alloc] initWithName:@"Default Configuration" sessionRole:connectingSceneSession.role];
}

- (**void**)application:(UIApplication *)application didDiscardSceneSessions:(NSSet<UISceneSession *> *)sceneSessions {
    // Called when the user discards a scene session.
    // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
    // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}

6. 删除SceneDelegate.h和SceneDelegate.m

7. 删除info.plist下的Application Scene Manifest

8. 删除TARGETS下info的Application Scene Manifest

clean一下 就可以了。
