google admob ios：请求错误：没有广告可显示

Question

我找到了一个相关的线程AdMob Ios Error: Failed to receive ad with error: Request Error: No ad to show，但它并没有解决我的问题。

我正在尝试使用来自谷歌代码的最新示例项目创建一个插页式广告：https://google-mobile-dev.googlecode.com/files/InterstitialExample_iOS_3.0.zip。

我已将 kSampleAdUnitID 更改为我的广告 ID。

昨天，当我点击Load Interstitial 时，我得到了Request Error: No ad to show。我必须点击 4-5 次才能工作。

今天，我使用相同的代码，但无论我点击多少次Load Interstitial，我都会收到上述错误。

这里有什么帮助吗？

我的实现如下——希望对你有所帮助：

@interface ViewController () <GADInterstitialDelegate>
@property (strong, nonatomic) GADInterstitial *interstitial;   
@end   


@implementation ViewController

#define MY_INTERSTITIAL_UNIT_ID @"...."

- (void)preLoadInterstitial {
    //Call this method as soon as you can - loadRequest will run in the background and your interstitial will be ready when you need to show it
    GADRequest *request = [GADRequest request];
    self.interstitial = [[GADInterstitial alloc] init];
    self.interstitial.delegate = self;
    self.interstitial.adUnitID = MY_INTERSTITIAL_UNIT_ID;
    [self.interstitial loadRequest:request];
 }

- (void)interstitialDidDismissScreen:(GADInterstitial *)ad
{
    //An interstitial object can only be used once - so it's useful to automatically load a new one when the current one is dismissed
    [self preLoadInterstitial];
}

- (void)interstitial:(GADInterstitial *)ad didFailToReceiveAdWithError:(GADRequestError *)error
{
    //If an error occurs and the interstitial is not received you might want to retry automatically after a certain interval
    [NSTimer scheduledTimerWithTimeInterval:3.0f target:self selector:@selector(preLoadInterstitial) userInfo:nil repeats:NO];
}

- (void) showInterstitial
{
    //Call this method when you want to show the interstitial - the method should double check that the interstitial has not been used before trying to present it
    if (!self.interstitial.hasBeenUsed) [self.interstitial presentFromRootViewController:self];
}

@end
