Answer 1

You can simply use plain C syntax, which is available in Objective-C:

const char myByteArray[] = {
    0x12,0x23,0x34,0x45,
    0x56,0x67,0x78,0x89,
    0x12,0x23,0x34,0x45,
    0x56,0x67,0x78,0x89 };

Answer 2

Either use the plain C solution given by mouviciel or read the class description of NSData and NSMutableData.
