Question

我最近根据本教程实现了admob（ver 7.9.1）奖励视频： https://firebase.google.com/docs/admob/ios/rewarded-video

但我无法使用此功能编译我的应用程序。我收到此错误：

Undefined symbols for architecture x86_64:
  "l_OBJC_PROTOCOL_$_GADRewardBasedVideoAdDelegate", referenced from:
      l_OBJC_CLASS_PROTOCOLS_$_ViewController in libFramework.a(ViewController.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see     invocation)

我以前实施过横幅广告和插页式广告，但效果很好。

有什么建议吗？

Answer 1

该错误告诉您您没有导入所需的标头。您import标题是GADRewardBasedVideoAd吗？

#import "GADRewardBasedVideoAd.h"

或者，您可以导入整个AdMob框架。例如：

@import GoogleMobileAds;

Google还在GitHub上提供了完整的GADRewardBasedVideoAd示例：RewardedVideoExample/ViewController.m

Answer 2

导入iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to 8081 # Apparently -A won't work. I have to replace the rule, not add it. But I don't know how to do it yet，一切正常。

GoogleMobileAds/GADRewardBasedVideoAdDelegate.h

Admob奖励视频GADRewardBasedVideoAdDelegate未定义的符号
