Hi,

please do not be offended, but you did not understand memory management 
in Obj-C.
You do not need these lines:
   NSFileHandle  *fh = [[NSFileHandle alloc] init];
   NSData *inData = [[NSData alloc] init];
Nevertheless you've to declare the ivars,
NSFileHandle  *fh;
NSData *inData;
but you do not have to alloc-init them. fileHandleForReadingAtPath: and 
readDataToEndOfFile]; both return autoreleased objects, which means all 
the alloc-init stuff is done for you. Please re-read your favorite Obj-C 
manual. Espacially the sections about memory management.
