NSURLSessionTask setting parameters with NSDictionary

Question

I'm almost certain that I recently saw an networking related method that allowed setting of URL parameters with an NSDictionary.

It was part of the new NSURLSession classes but I can't find it.

Essentially, instead of doing the url like...

@"www.blah.com/something.php?value=18&name=hello"

You could do...

theRequest.parameters = @{@"value":@18, @"name":@"hello"};

Am I imagining this or does this exist?

Why not write it your self? you can use that, just keep the right order when you put the values into the dictionary.

- (NSString *)makeURLFromDictionary:(NSString *)url values:(NSDictionary *)dictionary
  {
NSMutableString *string = [[NSMutableString alloc]initWithString:url];
[string appendString:@"?"];
for (id key in dictionary) {
    [string appendString:key];
    [string appendString:@"="];
    [string appendString:[dictionary objectForKey:key]];
    [string appendString:@"&"];
}
//this will remove the last &
[string deleteCharactersInRange:NSMakeRange([string length]-1, 1)];

return string;
}

Please just check the returned string, if I'm not wrong you should put it in reverse way, F.I.L.O(First in Last Out style).

enter the dict's values like this:

NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
[dict setObject:@"hello" forKey:@"name"];
[dict setObject:@"18" forKey:@"value"];

NSString *urlString = [self makeURLFromDictionary:@"www.blah.com/somthing.php" values:dict];

Hop i help you.
