加载广告

1.创建一个广告控制器，成为窗口根控制器

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // 进入广告界面
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    // 创建广告界面:展示启动界面
    TGADViewController *adVc = [[TGADViewController alloc] init];
    self.window.rootViewController = adVc;
    // 3.显示窗口 makeKey:UIApplication主窗口
    // 窗口会把根控制器的view添加到窗口
    [self.window makeKeyAndVisible];    
    return YES;
}
