iOS应用AdMob激励视频广告加载失败问题求助

Hey there, let's work through these AdMob rewarded video problems together—they're super common, and we'll get this sorted out!

First Issue: Custom Ad Unit ID Fails to Load, But Test ID Works #

Since test ads load successfully, your core AdMob integration is actually on the right track. The problem with your custom ID almost always boils down to one of these:

• Double-check your ad unit setup: Make sure you created a Rewarded Video ad unit in your AdMob dashboard, not a banner/interstitial unit. Copy-paste errors are easy here—verify the ID matches exactly what's in the dashboard.
• Wait for ad inventory: New ad units or newly registered apps often take 1-2 days to start serving live ads. If you just set this up, give it some time before troubleshooting further.
• Check AdMob account status: Ensure your app hasn't been restricted or flagged in the AdMob dashboard. If there's a policy violation or pending review, live ads won't serve.
• Network/blocking issues: On your test device, disable any ad-blocking apps or VPNs that might be interfering with AdMob's ad requests.

Second Issue: "Cannot find an ad network adapter: com.google.DummyAdapter" Warning on Real Device #

This warning can look scary, but it's often either benign or a quick fix:

• Benign test ad behavior: The DummyAdapter is used for AdMob's test ads, and sometimes this warning pops up even when test ads load correctly. If your test ads are working despite the warning, you can ignore it for now (it won't affect live ads).
• Fix missing framework links: If you want to eliminate the warning, confirm your integration is complete:
  • If using CocoaPods, make sure your Podfile includes pod 'Google-Mobile-Ads-SDK', run pod install again, and clean/rebuild your project.
  • If integrating manually, verify all required AdMob frameworks are added to your project (like GoogleMobileAds.framework) and that they're marked as "Embed & Sign" in your target's "Frameworks, Libraries, and Embedded Content" section.
• Check Info.plist config: Ensure you've added your GADApplicationIdentifier to Info.plist, and if you're using IDFA, include the NSAppTrackingUsageDescription key with a clear explanation for users.

Pro Debugging Tips #

To get more clarity on why your custom ad unit is failing, add these steps:

1. Enable detailed logging: In your app's startup code, add:

   GADMobileAds.sharedInstance().requestConfiguration.testDeviceIdentifiers = ["YOUR_DEVICE_ID"]
   

   Replace YOUR_DEVICE_ID with your real device's ID (you can find it in Xcode's device window or from the AdMob console's test device prompt).
2. Implement the ad failure delegate method: In your rewarded video ad delegate, add:

   func rewardedAd(_ rewardedAd: GADRewardedAd, didFailToLoadWithError error: Error) {
       print("Rewarded ad failed to load: \(error.localizedDescription)")
       print("Error code: \(error._code)")
   }
   

   The error code and message will tell you exactly what's going on (e.g., no ad inventory, invalid ad unit ID, etc.).

Give these steps a shot, and if you still run into issues, share the exact error message from the failure delegate—this will help zero in on the problem even faster!
