I had thought about seeing what I could crash with using

that seems hackish and unstable at best.
I was going to suggest a combination of -mutableBytes, strncpy(),
and -setLength, but this method sounds like exactly what you need.
I haven't tested all boundary cases, but it seems to work. I don't
see any reason not to use it.
Since NSMutableData is toll-free bridged with CFMutableData, why not
use CFDataDeleteBytes()? That should always do the right thing.
