将AdMob添加到IOS cocos2d-x 3.2时链接错误

Question

我试图将AdMob添加到cocos2d-x 3.2简单游戏中 使用Xcode 5.1 iOS 7.1
我遵循教程 https://developers.google.com/mobile-ads-sdk/docs/#ios
和 http://plaincode.blogspot.co.il/2014/02/example-of-admob-integration-in-cocos2d.html

并在＆＃34;其他链接标志中添加-ObjC标志＆＃34;

我收到错误链接：

Undefined symbols for architecture armv7s:
  "_GCControllerDidDisconnectNotification", referenced from:
      -[GCControllerConnectionEventHandler observerConnection:disconnection:] in libcocos2dx iOS.a(CCController-iOS.o)
  "_GCControllerDidConnectNotification", referenced from:

  "_OBJC_CLASS_$_GCController", referenced from:

     (maybe you meant: _OBJC_CLASS_$_GCControllerConnectionEventHandler)

      -[UIVideoViewWrapperIos setURL::] in libcocos2dx iOS.a(UIVideoPlayerIOS.o)
ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

当我删除-ObjC标志时 然后我得到了：

<Google> Category methods are not loaded. Make sure you link the Google Mobile Ads library using one of the -ObjC, -force_load, or -all_load linker flags. See https://developers.google.com/mobile-ads-sdk/docs/#ios for more information.

这里有什么问题？

Answer 1

  

-ObjC 加载实现Objective-C类或类别的静态归档库的所有成员。（https://developer.apple.com/library/mac/qa/qa1490/_index.html）

在cocos2d-x 3.2

中

CCController-iOS.mm - ＆gt; #import <GameController/GameController.h>
UIVideoPlayerIOS.mm - ＆gt; #import <MediaPlayer/MediaPlayer.h>

所以你得到了那些错误。

<强>解决方案： 只需添加以下框架BuildSettings - ＆gt;构建阶段 - ＆gt;链接二进制文件库

MediaPlayer.framework
GameController.framework

Answer 2

是的，原因是为AdMob支持添加了-ObjC标志。我已将MediaPlayer.framework添加到我的项目中，它为我解决了问题。

Answer 3

在libGoogleAdMobAds.a中添加Other Linker Flags的路径为我工作。注意我使用Mopub和Cocos2d-x 3.0。

Answer 4

AdMob iOS SDK 7.0版作为框架发布。如果使用它，则无需添加-ObjC链接器选项和额外依赖项。它还针对iOS 8.0进行了优化。如果切换到7.0，则所有链接错误都将消失。
