Answer 1

Once you have an NSString you can just use the methods in that class, like intValue or longValue or floatValue

Answer 2

To get the decimal and hexadecimal equivalents, you would do:

int number = 0xe; // or 0x3, 0x6, 0x8, 0x2

NSString * decimalString = [NSString stringWithFormat:@"%d", number];
NSString * hexString = [NSString stringWithFormat:@"%x", number];
