FBFinalClassViolationException：FBAdTimer是一個final類，不能被繼承

我們已經升級爲FBAudienceNetwork v.4.26，現在我們看到了以下未處理的運行時異常，我們試圖在Xcode運行單元測試目標的任何時間：FBFinalClassViolationException：FBAdTimer是一個final類，不能被繼承

奇怪的是，我們的代碼庫（包括所有的第三方依賴）內，該包含唯一的文件單詞「FBAdTimer」是：

λ ~/Projects/iOS/app/ IOS-6370* grep -iR "FBAdTimer" . 
Binary file ./Pods/FBAudienceNetwork/FBAudienceNetwork.framework/FBAudienceNetwork matches 
Binary file ./App.xcworkspace/xcuserdata/silver.xcuserdatad/UserInterfaceState.xcuserstate matches

據https://developers.facebook.com/bugs/147221075773612/，FBAudienceNetwork不能同時位於測試目標和加載它的主包中。解決方案是從Podfile中的測試目標中刪除依賴項：

target 'App' do 
    use_frameworks! 

    pod 'FBAudienceNetwork' # Only present in the main app target 
end 

target 'AppTests' do 

end
