阅读入口,在代理方法中进行判断即可

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    self.window.backgroundColor = [UIColor whiteColor];
    
    //选择根控制器 (根据是否有新版)
    [DifferChooseRoot chooseRootControllerWithWindow:self.window];
    
    
    [self.window makeKeyAndVisible];
    
    return YES;
}
