iOS 開發筆記 - Admob SDK: Must set the rootViewController property of GADBannerView before calling loadRequest

又有一陣子沒把玩 Admob 了 XD 每次把玩的方式不同，這次看到錯誤訊息：

<Google> Must set the rootViewController property of GADBannerView before calling loadRequest:

以及：

didFailToReceiveAdWithError:Error

其他訊息：

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

現況與解法：

@interface YourViewController() <GADBannerViewDelegate>

@property (nonatomic, strong) GADBannerView *banner;

@end

@implementation YourViewController

- (GADBannerView *)banner {
    if (!_banner) {
        // 468*60
        _banner = [[GADBannerView alloc] initWithAdSize:kGADAdSizeFullBanner];
        _banner.adUnitID = @"ca-app-pub-###############";
    }
    return _banner;
}

- (void)viewDidLoad {
    [super viewDidLoad];

    self.banner.frame = CGRectMake(0, self.view.frame.size.height > self.view.frame.size.width ? self.view.frame.size.width - 60 : self.view.frame.size.height - 60, 468, 60 );
    self.banner.delegate = self;
    [self.view addSubview:self.banner];

    // <Google> Must set the rootViewController property of GADBannerView before calling loadRequest:
    self.banner.rootViewController = self;

    GADRequest* req = [GADRequest request];
    // <Google> To get test ads on this device, call: request.testDevices = @[ GAD_SIMULATOR_ID ];
    req.testDevices = @[GAD_SIMULATOR_ID];
    [self.banner loadRequest:req];

    NSLog(@"self.banner: %@", self.banner);
}

- (void)adViewDidReceiveAd:(GADBannerView *)view
{
    NSLog(@"adViewDidReceiveAd");
}

- (void)adView:(GADBannerView *)view
didFailToReceiveAdWithError:(GADRequestError *)error
{
    NSLog(@"didFailToReceiveAdWithError:%@", error);
}

@end
