xcode创建不从main.storyboard启动的项目

1，删除Main.StroyBoard文件和SceneDelegate.h/.m文件

2，在info.plist文件中移除Application Scene Manifest.

3，删除TARGETS下info的Main storyboard file base name以及Application Scene Manifest

4，在AppDelegate.h添加window属性

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow * window;

@end

5，在AppDelegate.m添加window配置信息，示例如下

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    UIViewController *vc =[[UIViewController alloc]init];
    vc.view.backgroundColor = [UIColor yellowColor];
    self.window.rootViewController = vc;
    [self.window makeKeyAndVisible];
    return YES;
}

@end

同时删除AppDelegate.m的如下代码

- (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.
}

话外

此时模拟器运行项目打印台可能会提示Info.plist contained no UIScene configuration dictionary (looking for configuration named "(no name)"),此种提示不影响项目，如果介意，可按如下配置，在TARGETS下info里如下添加Application Scene Manifest即可消除提示
