Question

I am trying to get a SubString from a string

This is the method I am calling

-(NSString *)subStringBetweenStrings:(NSString*)str open:(NSString*)open close:(NSString *)close
{
    if ( str == nil || open == nil || close == nil )
        return nil;

    int start = [str rangeOfString:open].location;
    if (start != -1)
    {
        int end = [str rangeOfString:close].location;
        if ( end != -1)
        {
            return [str substringFromIndex:start]; // DONT WANT
        }
    }
    return nil;       
}

I have start point and i have End point. How can i get subString from start and end index
something like return [ str subStringWithRange:(start, end)];

Nitpicking …

• replace int start with NSUInteger, that’s how NSRange location is defined,
• don’t compare start to -1, but to NSNotFound

… answer …

return [str substringWithRange:NSMakeRange( start, end - start + 1 )]
