Rdio.framework Documentation

The Rdio iOS SDK lets developers call the web service API, authenticate users, and play full song streams or 30 second samples.

To get started:

#import <Rdio/Rdio.h>
Rdio *rdio = [[Rdio alloc] initWithClientId:@"YOUR CLIENT_ID" andSecret:@"YOUR CLIENT_SECRET" delegate:nil];
[rdio preparePlayerWithDelegate:nil];
[rdio.player play:@"t2742133"];

Please direct feature requests and bug reports to Developer Support, Rdio API Google Group, or Issue tracking on GitHub.
