How to convert CFDataRef into NSData ?

I have CFDataRef and I want to convert it into NSData. I am not getting how to do this.

anyone help me..

Answer 1

It's toll-free bridged, so you just have to cast it.

NSData *myData = (NSData *)myCFDataRef;

Answer 2

As @KrisMarkel said, you just have to transfer ownership to ARC like so:

Like so to transfer ownership:

NSData* data1 = (__bridge_transfer NSData*) data;

else to use the reference without transferring ownership:

NSData* data2 = (__bridge NSData*) data;
