应用程序未在iOS模拟器中运行

Question

我的应用在设备中运行时没有任何错误。但是在模拟器中运行时会发生很多链接错误。

以下是Google添加视图（横幅视图）的代码

-(void)loadAddMobConfigs{

switch ([UIDevice currentDevice].userInterfaceIdiom) {
    case UIUserInterfaceIdiomPhone:
        self.bannerSizes = @[ @"Large Banner", @"Banner", @"Smart Banner" ];
        break;
    case UIUserInterfaceIdiomPad:
        self.bannerSizes = @[
                             @"Large Banner", @"Banner", @"Smart Banner",
                             @"Full Banner",
                             @"Medium Rectangle",
                             @"Leaderboard"
                             ];
        break;
    case UIUserInterfaceIdiomUnspecified:
        self.bannerSizes = @[ @"Large Banner", @"Banner", @"Smart Banner" ];
        break;
    default:
        break;
}

self.ads = @{
             @"Banner" : NSValueFromGADAdSize(kGADAdSizeBanner),
             @"Large Banner" : NSValueFromGADAdSize(kGADAdSizeLargeBanner),
             @"Smart Banner Portrait" : NSValueFromGADAdSize(kGADAdSizeSmartBannerPortrait),
             @"Smart Banner Landscape" : NSValueFromGADAdSize(kGADAdSizeSmartBannerLandscape),
             @"Full Banner" : NSValueFromGADAdSize(kGADAdSizeFullBanner),
             @"Medium Rectangle" : NSValueFromGADAdSize(kGADAdSizeMediumRectangle),
             @"Leaderboard" : NSValueFromGADAdSize(kGADAdSizeLeaderboard)
             };

if (!self.bannerView)
{
    self.bannerView = [[GADBannerView alloc] init];
    self.bannerView.adUnitID = @"xxxxxxxxxxxxxxxxxx";
    self.bannerView.rootViewController = self;
    self.bannerView.delegate = self;
    [self.view addSubview:self.bannerView];
}

}

使用横幅广告
