How to find and replace symbols in a string?

Sorry if the following is really obvious, but I’m just starting to work with NSRange and found the docs not really helpful with my question.

I have a string and I would like to look through it, starting from the very end. I would like to determine the range from the end of the string to either (1) the first space OR (2) the first return.

This is what I have so far:

 NSRange range = [myString rangeOfString:@" " options:NSBackwardsSearch];

but how do I tell objective-C something like rangeOfString:@" " or @"/n"?

Thanks for any help or suggestions with this!

You can do something like this:

NSRange rangeSpace = [myString rangeOfString:@" " options:NSBackwardsSearch];
NSRange rangeReturn = [myString rangeOfString:@"/n" options:NSBackwardsSearch];

    if(rangeSpace.location < rangeReturn.location)
        //use rangeReturn
    else
        //use rangeSpace
