LastFm - block based Last.fm SDK for iOS and Mac OS X

Loosely based on LastFMService from the old Last.fm iPhone app, but non-blocking, more readable, much easier to use (and to extend) and with less dependencies.

Features

• Block based for easier usage
• Only one dependency (KissXML)
• Returns values in the correct data type (NSDate, NSURL, NSNumber, etc)
• Hook in your own caching methods (GVCache, NSCache, Core Data, SYCache, EGOCache, ...)
• Cancelable operations, perfect for when cells are scrolled off screen and you don't need to make the API calls after all
• Actively developed and maintained (it's used in the official Last.fm Scrobbler app!)

Usage

// Set the Last.fm session info
[LastFm sharedInstance].apiKey = @"xxx";
[LastFm sharedInstance].apiSecret = @"xxx";
[LastFm sharedInstance].session = session;
[LastFm sharedInstance].username = username;

// Get artist info
[[LastFm sharedInstance] getInfoForArtist:@"Pink Floyd" successHandler:^(NSDictionary *result) {
    NSLog(@"result: %@", result);
} failureHandler:^(NSError *error) {
    NSLog(@"error: %@", error);
}];

// Scrobble a track
[[LastFm sharedInstance] sendScrobbledTrack:@"Wish You Were Here" byArtist:@"Pink Floyd" onAlbum:@"Wish You Were Here" withDuration:534 atTimestamp:(int)[[NSDate date] timeIntervalSince1970] successHandler:^(NSDictionary *result) {
    NSLog(@"result: %@", result);
} failureHandler:^(NSError *error) {
    NSLog(@"error: %@", error);
}];

Save the username and session you get with getSessionForUser:password:successHandler:failureHandler: somewhere, for example in NSUserDefaults, and on app start up set it back on [LastFm sharedInstance].username and [LastFm sharedInstance].session.

See the included iOS project for examples on login, logout, getting artist info and more.

Example app

There's an extensive example app available which handles login, logout, getting lots of artists in a tableview and showing their details, caching, canceling API calls, and much more.

To install the example app, you need to use CocoaPods: pod install. You can also try it by running pod try LastFm.

The example app only works in iOS 5 and higher due to the usage of storyboards. The SDK itself works in iOS 4 and higher.

Installation

You can install LastFm with CocoaPods. Just add the following line to your Podfile, and run pod install:

pod 'LastFm'

You can also simply clone the repository and drag the LastFm subfolder into your Xcode project. Be sure to install KissXML yourself.

Requirements

• LastFm is built using ARC and modern Objective-C syntax. You will need iOS 4 and Xcode 4.4 or higher to use it in your project.
• You will need your own API key by registering at http://www.last.fm/api.
• KissXML
