New error for architecture armv7 in MMTAppController

Hi,
I have an issue with my game and Xcode 6.3.1, I have built my game with Unity 4.6.1 free for iOS.
In my game there is this plugin:
- Google Play SDK
- Unity ADS
- Facebook SDK
- Pushwoosh SDK

I have solved all issue with all external plugin and framework, but now it appeared an error saying:

Code (Xcode Errors):

1. Undefined symbols for architecture armv7:
2.   "_MMTUnitySetGraphicsDevice", referenced from:
3.       -[MMTAppController shouldAttachRenderDelegate] in MMTAppController.o
4.   "_MMTUnityRenderEvent", referenced from:
5.       -[MMTAppController shouldAttachRenderDelegate] in MMTAppController.o
6. ld: symbol(s) not found for architecture armv7
7. clang: error: linker command failed with exit code 1 (use -v to see invocation)

And this is the MMTAppController.mm (maybe can help you to understand the errors)

Code (CSharp):

1. #import <UIKit/UIKit.h>
2. #import "UnityAppController.h"
3.  
4. extern "C" void MMTUnitySetGraphicsDevice(void* device, int deviceType, int eventType);
5. extern "C" void MMTUnityRenderEvent(int marker);
6.  
7. @interface MMTAppController : UnityAppController
8. {
9. }
10. - (void)shouldAttachRenderDelegate;
11. @end
12.  
13. @implementation MMTAppController
14.  
15. - (void)shouldAttachRenderDelegate;
16. {
17.     UnityRegisterRenderingPlugin(&MMTUnitySetGraphicsDevice, &MMTUnityRenderEvent);
18. }
19. @end
20.  
21.  
22. IMPL_APP_CONTROLLER_SUBCLASS(MMTAppController)

Thanks you!
