I just tackled such a problem and this will give you the solution you

very misleading in that one understands the -(NSData

that,
compress the image using the specified compression... it doesn't... in
fact, I haven't found anything that it does do that is useful...
Hopefully someone at Apple can shed some insight on this function.
After
looking at it, and talking with a few others, it seems like it does
nothing,
or at the very least it does nothing useful.
TIFF files can have different types of compression... JPEG, LZW (at
least it was supported before) and I think one other, but i can't
remember off the top.
play with tiffutil to see the differing results..
