用于iOS 8扩展的AFNetworking后台会话配置

问题描述

我目前正在开发iOS 8 App扩展程序，并且在最后一篇文章中遇到了困难。在我的应用程序的其余部分，我使用AFHTTPSessionManager子类，我实例化如下：

I'm currently developing an iOS 8 App Extension, and am having difficulty with this one last piece. In the rest of my app, I use an AFHTTPSessionManager subclass that I instantiate like this:

+ (MYAPIClient *)sharedClient {
    static MYAPIClient *_sharedClient = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _sharedClient = [[MYAPIClient alloc] initWithBaseURL:[NSURL URLWithString:kMYBaseURL]];
        _sharedClient.requestSerializer = [[MYAPIRequestSerializer alloc] init];
        _sharedClient.responseSerializer = [[MYAPIResponseSerializer alloc] init];
    });
    return _sharedClient;
}

当我刚刚使用这个常规API客户端时，只需在共享中发布一些文本扩展工作正常，它甚至有时适用于图像（虽然通常会失败），但我知道我需要使用后台会话配置。所以我用这样的后台配置设置了一个非常相似的api客户端：

When I just used this regular API client, just posting some text form a share extension worked fine, and it even works for images sometimes (usually fails though), but I know that I need to be using a background session configuration. So I made a very similar api client with a background configuration setup like this:

+ (MYAPIClient *)sharedBackgroundClient {
    static MYAPIClient *_sharedClient = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{

        NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:@"com.me.myapp.backgroundconfiguration"];
        _sharedClient = [[MYAPIClient alloc] initWithBaseURL:[NSURL URLWithString:kMYBaseURL] sessionConfiguration:sessionConfiguration];
        _sharedClient.requestSerializer = [[MYAPIRequestSerializer alloc] init];
        _sharedClient.responseSerializer = [[MYAPIResponseSerializer alloc] init];
    });
    return _sharedClient;
}

问题是，当我使用这个客户端进行POST时，我得到了这些每次都是错误的。

The problem is, when I make my POST using this client, I get these erros every single time.

Aug 21 19:19:07 MY-iPhone Share[6290] <Notice>: Attempted to create a task in a session that has been invalidated
Aug 21 19:19:07 MY-iPhone Share[6290] <Warning>: *** Assertion failure in -[MYAPIClient setDelegate:forTask:], /Users/me/Documents/myproject/myproduct/Pods/AFNetworking/AFNetworking/AFURLSessionManager.m:337
Aug 21 19:19:07 MY-iPhone Share[6290] <Error>: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: task' 

有关如何获取的任何建议让这个工作？非常感谢。

Any advice on how to get this to work? Thanks a lot.

请参阅，以获取有关设置共享容器的指导。

Refer to Sharing Data with Your Containing App for guidance on setting up a shared container.

在您的示例中，您将添加以下内容：

In your example, you'd add something like:

sessionConfiguration.sharedContainerIdentifier = @"com.me.myapp.containerIdentifier";

您需要为包含应用程序提供一个后台会话，并为其扩展程序提供一个后台会话。

You'll need one background session for the containing app and one for its extension.
