  • 禁用SceneDelegate

    首先删除 SceneDelegate.hSceneDelegate.m ,info.plist中的 Application Scene ManifestAppDelegate.m 中的

    #pragma mark - UISceneSession lifecycle
    
    - (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.
    }
    

    接着在 AppDelegate.hAppDelegate.m 中增加

    @property (strong, nonatomic) UIWindow * window;
    

    如果需要自己创建 window 按照原来的方法创建即可,不创建的话也可以使用 Main.storyboard

    
    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    	self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
        self.window.backgroundColor = [UIColor whiteColor];
        [self.window makeKeyWindow];
        [self.window makeKeyAndVisible];
        return YES;
    
    }
