蘋果Mach-O爲libAppLovinSdk.a在iPhone的cocos2d

Question

我想在我的cocos2d項目在Xcode中顯示AppLovin sdk，我目前無法調試這個Apple Mach-O錯誤，如下所述。

Undefined symbols for architecture i386: 
    "_CMTimeGetSeconds", referenced from: 
     -[ALVideoViewController timeLeft] in libAppLovinSdk.a(ALVideoViewController.o) 
     -[ALVideoViewController percentViewed] in libAppLovinSdk.a(ALVideoViewController.o) 
    "_CMTimeMakeWithSeconds", referenced from: 
     -[ALVideoViewController createCountdownTimeObserver] in libAppLovinSdk.a(ALVideoViewController.o) 
    "_MPMoviePlayerPlaybackDidFinishNotification", referenced from: 
     ___50-[ALInterstitialViewController prepareForVideoAd:]_block_invoke in libAppLovinSdk.a(ALInterstitialViewController.o) 
    "_MPMoviePlayerPlaybackDidFinishReasonUserInfoKey", referenced from: 
     ___53-[ALInterstitialViewController moviePlayerDidFinish:]_block_invoke in libAppLovinSdk.a(ALInterstitialViewController.o) 
    "_MPMoviePlayerPlaybackStateDidChangeNotification", referenced from: 
     ___50-[ALInterstitialViewController prepareForVideoAd:]_block_invoke in libAppLovinSdk.a(ALInterstitialViewController.o) 
    "_OBJC_CLASS_$_MPMoviePlayerController", referenced from: 
     objc-class-ref in libAppLovinSdk.a(ALInterstitialViewController.o) 
ld: symbol(s) not found for architecture i386 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

我去構建階段 - >添加其他 - >選擇libAppLovinSdk.a從顯示的數據庫文件。

我還將Build Active Architectures的值設置爲NO，並從體系結構中刪除arm64。沒有i386架構。

您缺少CoreMedia和MediaPlayer框架。

（我發現了這一點，通過谷歌搜索CMTimeGetSeconds和MPMoviePlayerPlaybackDidFinishNotification和看到的蘋果文檔的部分得到了命中率，但是CM和MP前綴應該足以告訴你）。
