how to convert byte value into int in objective-c

Question

Please tell me how to convert bytes to NSInteger/int in objective-c in iPhone programming?

Answer 1

My guess:

unsigned char data[] = { 0x00, 0x02, 0x45, 0x28 };
NSInteger intData = *((NSInteger *)data);

NSLog(@"data:%d", intData); // data:675611136
NSLog(@"data:%08x", intData); // data:28450200

So, beware of byte-order.
