iOS - Simple Resampling audio function for iOS

Question

I am using Novocaine for recording audio, for an audio processing iOS app. I have a custom audio filter, which I apply after recording. Now I want the Audio to be resampled at 8kHz. So basically I need a simple module/function in which I pass the audio data buffer, and simply get a Resampled Audio.

I have looked on internet but found no generic resampling audio data solution as per my requirement for iOS.

Please help me, I shall be very thankful to you.
