Add MIME Types to GroundControl Remote Config

GroundControl is an amazing library by Mattt Thompson that provides you a simple way to enable remote configuration of your Cocoa app.

GroundControl is part of Helios, a bigger set of libraries worth checking out, and is based on AFNetworking, which you might already be using.

One of the issues I run into when using GroundControl for the first time, was that the remote plist was hosted in Dropbox, and the returned MIME type was plain/text instead of the expected application/x-plist.

Since GroundControl is based on AFNetworking, this is easy to fix. Just add the MIME Type to AFPropertyListRequestOperation as follows:

Adding MIME Types to GroundControl
NSURL *url = /* your URL */;
[AFPropertyListRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/plain"]];
[[NSUserDefaults standardUserDefaults] registerDefaultsWithURL:url
success:^(NSDictionary *defaults) {
}
failure:^(NSError *error) {
}
];
