软件简介

OctoKit 是用于和 Github API 交互的 Cocoa 和 Cocoa Touch
框架，它由
AFNetworking、Mantle、和ReactiveCocoa
建立。

示例代码：

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    RACDisposable *disposable = [[[[self.client
        fetchUserRepositories]
        collect]
        deliverOn:RACScheduler.mainThreadScheduler]
        subscribeNext:^(NSArray *repositories) {
            [self addTableViewRowsForRepositories:repositories];
        } error:^(NSError *error) {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Whoops!"
                                                            message:@"Something went wrong."
                                                           delegate:nil
                                                  cancelButtonTitle:nil
                                                  otherButtonTitles:nil];
            [alert show];
        }];    // Save the disposable into a `strong` property, so we can access it later.
    self.repositoriesDisposable = disposable;
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];    
    // Cancels the request for repositories if it's still in progress. If the
    // request already terminated, nothing happens.
    [self.repositoriesDisposable dispose];
}
