我开发了一个应用程序，我想添加 Admob。
我无法运行 Admob 测试 Bannerview。
代码：
// Create a view of the standard size at the top of the screen.
// Available AdSize constants are explained in GADAdSize.h.
bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];
//bannerView_.frame = CGRectMake(0, 200, 320, 50);
// Specify the ad's "unit identifier." This is your AdMob Publisher ID.
bannerView_.adUnitID = @"a15188d33246d24";
// Let the runtime know which UIViewController to restore after taking
// the user wherever the ad goes and add it to the view hierarchy.
bannerView_.rootViewController = self;
[self.view2 addSubview:bannerView_];
// Initiate a generic request to load it with an ad.
[bannerView_ loadRequest:[GADRequest request]];
错误是：
tableViewKullanimi[13107:c07] <Google> To get test ads on this device, call:
request.testDevices = [NSArray arrayWithObjects:GAD_SIMULATOR_ID, nil];
