Question

How can I display the following bytes using NSLog?

const void *devTokenBytes = [devToken bytes];

Answer 1

If you want a hex sequence:

NSMutableString *hex = [NSMutableString stringWithCapacity:[devToken length]];
for (int i=0; i < [devToken length]; i++) {
  [hex appendFormat:@"%02x", [devToken bytes][i]];
}
