Question

I use NSString stringWithFormat method for create an URL string. But now I have problem with a “quick” editing this string.

For example I have an script on the server that process some request with parameters.

I have an URL string like this:

http://www.domain.com/api/?param1=%@&param2=%@&param3=%@&param4=%@&param5=%@&

but when I have more than 5, 6 parameters it is really hard to modify this string.

Anybody knows best method how to create URL string (I mean when we modify it).

I wrote this specially for you, quite simple:

+ (NSString*) URlStringForBaseURL:(NSString*)baseURL withParams:(NSDictionary*)paramsdictonary{
NSString* url = [baseURL stringByAppendingString:@"?"];
NSUInteger index = 0;
for (NSString* key in [paramsdictonary allKeys]) {
    index++;
    if (index == [paramsdictonary count]) 
        url =  [url stringByAppendingFormat:@"%@=%@",key,[paramsdictonary valueForKey:key]];
    else
        url =  [url stringByAppendingFormat:@"%@=%@&",key,[paramsdictonary valueForKey:key]];
}
return url;
}

And you can use it (of course, the order of the URL params is dos not matter):

NSMutableDictionary* params = [NSMutableDictionary dictionary];
[params setValue:@"value1" forKey:@"param1"];
[params setValue:@"value2" forKey:@"param2"];
[params setValue:@"value3" forKey:@"param3"];

NSString* urlStr = [HTMLTextFormat URlStringForBaseURL:@"http://www.domain.com/api/" withParams:params];

NSLog(@"url_: %@",urlStr);
