Best way to parse URL string to get values for keys?

Question

I need to parse a URL string like this one:

&ad_eurl=http://www.youtube.com/video/4bL4FI1Gz6s&hl=it_IT&iv_logging_level=3&ad_flags=0&ends         


        

Answer 1

-(NSArray *)getDataOfQueryString:(NSString *)url{
    NSArray *strURLParse = [url componentsSeparatedByString:@"?"];
    NSMutableArray *arrQueryStringData = [[NSMutableArray alloc] init];
    if ([strURLParse count] < 2) {
        return arrQueryStringData;
    }
    NSArray *arrQueryString = [[strURLParse objectAtIndex:1] componentsSeparatedByString:@"&"];

    for (int i=0; i < [arrQueryString count]; i++) {
        NSMutableDictionary *dicQueryStringElement = [[NSMutableDictionary alloc]init];
        NSArray *arrElement = [[arrQueryString objectAtIndex:i] componentsSeparatedByString:@"="];
        if ([arrElement count] == 2) {
            [dicQueryStringElement setObject:[arrElement objectAtIndex:1] forKey:[arrElement objectAtIndex:0]];
        }
        [arrQueryStringData addObject:dicQueryStringElement];
    }

    return arrQueryStringData; 
}

You this function just Pass URL and you will get all the element of querystring.
