Drupal iOS SDK - Connect your iOS/OS X app to Drupal

What you need to know

The Drupal iOS SDK is a standard set of libraries for communicating to Drupal from any iOS device. Its extremely simple. This GETs you a Drupal node and stores it in an NSDictionary, myNode.

DIOSNode *node = [[DIOSNode alloc] initWithSession:session];
NSDictionary *myNode = [node nodeGet:1];
[node release];

What you need to get started

####XCode

• This library
• the following frameworks
  • UIKit.Framework
  • CoreGraphics.framework
  • CFNetwork.framework
  • libz.1.2.3.dylib
  • SystemConfiguration.framework
  • MobileCoreServices.framework
  • ASIHTTPRequest which can be found here
• Update DIOSConfig.h with the correct API_KEYS SERVICES_URL and DOMAIN (make sure you checkout the drupal-ios-sdk branch for your version of drupal eg. 6.x-2.x, 6.x-3.x or 7.x-3.x)

####Drupal 6.x-2.x (NOT RECOMMENDED, Services 2.x is running 5 year old code. I would suggest using 3.x now that it is in RC stage.

• PLIST Server
• services 2.4

####Drupal 6.x-3.x and 7.x-3.x (RECOMMENDED)

• Services
• REST SERVER PLIST

####Note, Services 3.x does not have an API key, it doesn't use them, IT HAS BEEN REMOVED. Use oAuth if you need extra Security.

Demo Code (Code is pulled from http://github.com/workhabitinc/drupal-ios-sdk-example)

[nodeData setObject:@"1" forKey:@"status"];
[nodeData setObject:[[session userInfo] objectForKey:@"name"] forKey:@"name"];
[node nodeSave:nodeData];
[node release];

[userData setObject:[emailSaveField text] forKey:@"mail"];
[userData setObject:[uidSaveField text] forKey:@"uid"];
[user userSave:userData];

DIOSUser *user = [[DIOSUser alloc] initWithSession:session];
[user userGet:[uidGetField text]];
[user release];

[user userDelete:[uidDeleteField text]];
[user release];

Taxonomy

- (NSMutableArray *) getTreeForVid:(NSString*)vid {
  DIOSTaxonomy *taxonomy = [[DIOSTaxonomy alloc] initWithSession:session];
  return [[taxonomy getTree:vid] objectForKey:@"#data"];
}

- (NSMutableArray *) getNodesForTid:(NSString*)tid {
  DIOSTaxonomy *taxonomy = [[DIOSTaxonomy alloc] initWithSession:session];
  
  return [[taxonomy selectNodes:tid] objectForKey:@"#data"];
}

Troubleshooting

If you are getting Access denied, or API Key not valid, double check that your key settings are setup correctly at admin/build/services/keys and double check that permissions are correct for your user and anonymous.

X service doesnt exist in Drupal iOS SDK

Thats ok, just subclass DIOSConnect and follow the model of tthe other DIOS classes. If its a core services Class and I have not added it in, please help us all out and contribute it by by doing a pull request. Thanks!
