I've been unsuccessful finding the right class in cocoa to help me parse integers inside NSStrings. I'm looking for something similar to java's Long.parseInt(string, radix). i.e. something that can understand a stream of numbers along with a specified radix (which may be 8, 10 or 16 in my use cases).
What is available to help out here?
Thanks!

For base 10, -[NSString integerValue] will do the trick, for other bases, you can either use NSScanner, or just fall back to libc function:

strtol([myString UTF8String], NULL, 16);

I don't remember if -UTF8String may returns NULL. If this is the case, you should test the value before passing it to strtol.
