在其他链接器标志"中添加 -ObjC 标志后

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

我收到链接错误:

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

  "_OBJC_CLASS_$_GCController", referenced from:

     (maybe you meant: _OBJC_CLASS_$_GCControllerConnectionEventHandler)

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:

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.

这里有什么问题?

推荐答案

-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)

-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

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>

所以你得到了这些错误.

so you got those errors.

解决方案:只需添加以下框架 BuildSettings -> Build Phase -> Link Binary with libraries

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

MediaPlayer.framework
GameController.framework
