Objective-C: How to add query parameter to NSURL?

Question

Let\'s say I have an NSURL? Whether or not it already has an empty query string, how do I add one or more parameters to the query of the NSUR

Answer 1

If you're using RestKit it provides additions to NSString. One of which is:

- (NSString *)stringByAppendingQueryParameters:(NSDictionary *)queryParameters

So you could do:

NSDictionary *shopParams = [NSDictionary dictionaryWithKeysAndObjects:
                                @"limit",@"20", 
                                @"location",@"latitude,longitude",
                                nil];
NSString *pathWithQuery = [@"/api/v1/shops.json" stringByAppendingQueryParameters:shopParams]
