How to display hexadecimal bytes using NSLog

Question

How can I display the following bytes using NSLog?

const void *devTokenBytes = [devToken bytes];

Answer 1

Assuming that devToken is of type NSData * (from the bytes call), you can use the description method on NSData to get a string containing the hexadecimal representation of the data's bytes. See the NSData class reference.

NSLog(@"bytes in hex: %@", [devToken description]);
