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
