AdMob test banner loads on simulator, Only real banner loads on device?

Question

I can't get a test banner to load on a device. However, test banner loads on simulator no problem. I'm trying to test my AdMob/iAd singleton mediation. It works fine with test ads on simulator but AdMob never loads the test banner on actual device.

The following is the code to present AdMob banner:

    self.adBanner_=[[GADBannerView alloc]initWithFrame:CGRectMake(0, 0, 320, 50)]; 

    adBanner_.hidden=NO;

    adBanner_.delegate = self;   

    adBanner_.adUnitID = @"Unit-ID";

    GADRequest *request = [GADRequest request];

    [self.adBanner_ loadRequest:request];

    self.adBanner_.rootViewController = self;

    [self.view addSubview:self.adBanner_];   

    isLoaded_ = YES;   

    //  request.testDevices = @[ GAD_SIMULATOR_ID ]; <--loads test ad on simulator

    request.testDevices = @[ @"number" ];  <--supposed to load test ads on real device

Why aren't I receiving AdMob test ads on real device yet there's no problem with AdMob test ads on simulator? Is code wrong?

Answer 1

Just run your app on your test device. In the Debug Area AdMob will give you your test ID like so:

<Google> To get test ads on this device, call: request.testDevices = @[ @"testDeviceIDNumber" ]

After that just place your testDeviceIDNumber here:

GADRequest *request = [GADRequest request];
request.testDevices = @[ @"testDeviceNumberIDNumber"];
[self.adBanner_ loadRequest:request];

For keep testing on the simulator also, add @"Simulator" in this row:

request.testDevices = @[ @"testDeviceNumberIDNumber", @"Simulator"];
