NSMutableData remove bytes?

Question

I can add bytes to a NSMutableData instance easily by using the appendData method, however I do not see any similar method for removing data? Am I overlooking somet

Answer 1

Since NSMutableData is toll-free bridged with CFMutableDataRef, you can use the CFDataDeleteBytes() function:

NSMutableData *data = ...
CFDataDeleteBytes((CFMutableDataRef)data, CFRangeMake(3, 4));
