For 32 bit Integers:

char buffer[enough_space_for_the_largest_string..];
sprintf (buffer, "%08x", YourNumber);

NSString *hexString = [NSString stringWithFormat:@"%x", yourNumber];

The printf format specifiers %x and %X allow you to print an integer's hex representation. The same can be used with [NSString stringWithFormat:...] to get an Objective-C string.
