Flurry广告库未定义架构armv7的符号：

Question

我想在我的新应用程序中使用Flurry广告。我已经安装了分析软件包，喜欢它的易于跟踪用户和事件的功能。

然而，在使用新的4.0.1 SDK实现广告时，我遇到了一个错误，但我找不到解决方法。每次尝试构建我的Xcode 4.2项目时，我都会收到以下错误消息:

Undefined symbols for architecture armv7:
  "_MPMoviePlayerLoadStateDidChangeNotification", referenced from:
  -[FlurryVideoPlayer playVideo:view:ad:] in libFlurryAds.a(FlurryVideoPlayer.o)
  -[FlurryVideoPlayer moviePlayerLoadStateChanged:] in libFlurryAds.a(FlurryVideoPlayer.o)

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

显然我的FlurryAds.a库出现了问题。我已经尝试多次完全按照Flurry广告指南的步骤进行操作，但是尽管我已经尽力了，我仍然遇到了这个错误。我的库在构建阶段内得到了正确的链接，并且我已经尽力实现了此处描述的修复措施Undefined symbols for architecture armv7，但是没有成功。

有任何想法吗？非常感谢您的帮助。

我也遇到了XCode 5.1相同的错误。

我通过在项目中链接MediaPlayer.framework和AdSupport.framework来解决这个问题。
