Question

How to read rest of bytes after 24 bytes from a NSData variable in objective c?

Answer 1

You can use the subdataWithRange: method of NSData to get an NSData object with the data after the first 24 bytes.

You would do something like:

NSData *newData = [data subdataWithRange:NSMakeRange(24, [data length] - 24)];

There is also the getBytes:range: method that returns the bytes in a buffer.
