SBNotificationHub error in iOS

We are using notification hub in "Windows Azure" service bus to send push notifications to iPhone. On working on a new app , and after uploading the push certificate of app as written , it doesn't send push notifications no more , and then it stops sending push notifications on other hubs

So I decided to work on the new version of "Windows Azure SDK" of iOS

I downloaded it from the windows azure downloads 

and the filename was : 

azuresdk-iOS-v1.1.3 

By checking the tutorial , I put the "WindowsAzure.FrameWork" to the project frameworks 

When building it on the device after writing the code , it gives me the error : 

Undefined symbols for architecture armv7s:

clang: error: linker command failed with exit code 1 (use -v to see invocation) 

Note : By following stack overflow and MSDN library , I tried to try a solution as setting "Architectures" in "Build Settings" to "Standard Architectures" and still the same error  

Note : Another solution was to add the ".m" files to "compile" sources in "Build phases" which makes me doubt the the compiler can't see the implementation files of the library 

Thanks in advance
