NSString Range how it works?

Question

I'm just playing around with Xcode, and now using Xcode to find some string in another string. And problem here is that it doesn't show what I expect. (It shows "No match found!") Any tips, please? Thanks,

And my code is :

int main(int argc, const char * argv[])
{

    @autoreleasepool {



        NSString *listOfNames = @"huhuWARDdsfadfadsfsadfafsfsadfafr";
        NSString *capListOfNames = [listOfNames capitalizedString];

        NSString *name = @"WaRd";
        NSString *capName = [name capitalizedString];



        NSRange match = [capListOfNames rangeOfString:capName];
        if (match.location == NSNotFound)
        {
            NSLog(@"No match faound!");
        }else{
            NSLog(@"Found!");
            NSLog(@"location : %d",(int)match.location);
            NSLog(@"length : %d",(int)match.length);


        }


    }
    return 0;
}

Answer 1

capitalizedString returns your string with an uppercase first letter and the rest lowercase.

Try again with capName = [name uppercaseString];

Currently, you're looking for "Ward" in a string that doesn't contain "Ward" (though it does contain "WARD").

EDIT: capitalizedString makes the first letter in each word of the string upper case, and the rest lower case.

Also, you can do this:

NSRange match = [capListOfNames rangeOfString:capName 
                                      options:NSCaseInsensitiveSearch];

Which, well, performs a case-insensitive search...

Answer 2

capitalizedString only makes the first letter capitalized, use uppercaseString instead to achive what you expect.
