Create a collection and then use NSJSONSerialization to create JSON data representation. Use the resulting data as the POST data.

NSDictionary *parameters = @{
  @"title": @"Design Milk",
  @"id": @"feed/http://feeds.feedburner.com/design-milk",
  @"categories": @[
          @{
              @"id": @"user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/design",
              @"label": @"design"
              },
          @{
              @"id": @"user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/weekly",
              @"label": @"weekly"
              },
          @{
              @"id": @"user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/global.must",
              @"label": @"must reads"
              }
          ]
};

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictData options:0 error:&error];
