将AdMob添加到IOS cocos2d-x 3.2时出现链接错误 [英] Linking errors when adding AdMob to IOS cocos2d-x 3.2

问题描述

我试图按照
中的教程，使用Xcode 5.1 iOS 7.1将AdMob添加到cocos2d-x 3.2简单游戏中


i > https://developers.google.com/mobile-ads-sdk/docs/#ios

和
http://plaincode.blogspot.co.il/2014/02/example-of-admob-integration-in-cocos2d.html

和在其他链接器标志中添加-ObjC标志

and after adding the -ObjC flag in the "Other Linker Flags"

我遇到链接错误：

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

  "_OBJC_CLASS_$_GCController", referenced from:
      objc-class-ref in libcocos2dx iOS.a(CCController-iOS.o)
     (maybe you meant: _OBJC_CLASS_$_GCControllerConnectionEventHandler)
  "_MPMoviePlayerPlaybackStateDidChangeNotification", referenced from:
      -[UIVideoViewWrapperIos dealloc] in libcocos2dx iOS.a(UIVideoPlayerIOS.o)
      -[UIVideoViewWrapperIos setURL::] in libcocos2dx iOS.a(UIVideoPlayerIOS.o)
  "_MPMoviePlayerPlaybackDidFinishNotification", referenced from:
      -[UIVideoViewWrapperIos dealloc] in libcocos2dx iOS.a(UIVideoPlayerIOS.o)
      -[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，我得到：

when i removing the -ObjC flag then I'm getting :

<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.

这里出了什么问题？

推荐答案

-ObjC 加载实现了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 ）

-ObjC Loads all members of static archive libraries that implement an Objective-C class or category.(https://developer.apple.com/library/mac/qa/qa1490/_index.html)

在cocos2d-x 3.2中

In cocos2d-x 3.2

CCController-iOS.mm-> #import< GameController / GameController.h>

UIVideoPlayerIOS.mm-> #import< MediaPlayer / MediaPlayer.h>

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

所以您遇到了这些错误。

so you got those errors.

解决方案：
只需添加以下框架BuildSettings-> Build Phase->将二进制文件与库链接

Solution: Just add following frameworks BuildSettings -> Build Phase -> Link Binary with libraries

MediaPlayer.framework
GameController.framework
