AUGraph Record and Play - audiounit

Question

When I use AUGraph to implemention record and play, I want to get audio data through RenderCallback.There is a problem in remote io unit callback with error kAudioConverterErr_InvalidInputSize(1768846202),I don't know how to solve it.
Is there any other way to get audio data?
