How can I use query string (--data-urlencode) in an NSMutableURLRequest?
You may encode the string using the -[NSString stringByAddingPercentEscapesUsingEncoding:] method. Then, you just need to append the string to the URL.
NSString *URLPrefix = @"https://api.parse.com/1/classes/RandomObject";NSString *encodedQuery = [@"where={\"arrayKey\":2}" stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:@"%@?%@", URLPrefix, encodedQuery]];[request setURL:URL];
