ios项目去掉默认storyboard

1.注掉info.plist中的下面部分

<!--    <key>UILaunchStoryboardName</key>-->

<!--    <string>LaunchScreen</string>-->

<!--    <key>UIMainStoryboardFile</key>-->

<!--    <string>Main</string>-->

2.添加如下代码

    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    
        UIViewController *rootVC = [[UIViewController alloc] init];
    
        rootVC.view.backgroundColor = [UIColor blueColor];
    
        self.window.rootViewController = rootVC;
    
        self.window.backgroundColor = [UIColor whiteColor];
    
        [self.window makeKeyAndVisible];
    

    //以下为自定义代码，上面的六行代码为适配代码
    NSArray *views = [[NSBundle mainBundle] loadNibNamed:@"View" owner:self options:nil];
    [self.window addSubview:[views lastObject]];
