ASINetworkQueue setQueueDidFinishSelector 选择器过早结束？答案

【问题标题】：ASINetworkQueue setQueueDidFinishSelector selector ending prematurely ?ASINetworkQueue setQueueDidFinishSelector 选择器过早结束？

【问题描述】：

我刚刚开始测试我构建的一些上传实用程序并放置了 47 个项目进行上传，但队列在第 15、18 或 21 个项目随机停止，不知道确切原因，但选择器被调用得太早虽然不是所有的请求都结束了。

我做的唯一一件特别的事情是将最大并发请求数提高到 6 而不是 4 ，但是这似乎不是一个大问题。

我正在按如下方式配置我的选择器：

[self.uploadQueue setDelegate: self];
[self.uploadQueue cancelAllOperations];
[self.uploadQueue setRequestDidStartSelector: @selector(uploadRequestStarted:)];
[self.uploadQueue setRequestDidFinishSelector:@selector(uploadRequestEnded:)];
[self.uploadQueue setQueueDidFinishSelector:@selector(uploadQueueEnded:)];
[self.uploadQueue setDownloadProgressDelegate: myProgress];
[self.uploadQueue showAccurateProgress];

这是我的日志：

很想听听你们的任何建议:) 提前致谢，谢。

【解决方案1】：

您是否尝试将 setShouldCancelAllRequestsOnFailure: 设置为 NO ？如果任何单个请求失败，队列的默认行为是取消所有剩余的请求。

可能是请求失败（出于某种原因）导致您的队列提前完成。

【讨论】：

是的，我正要发布这个。还添加一个带有一些调试的 requestFailed 选择器，以便您了解是否/为什么会失败！
嘿，谢谢，这确实解决了！我得到的是 Error Domain=ASIHTTPRequestErrorDomain Code=2 "The request timed out" UserInfo=0x60ed4a0 {NSLocalizedDescription=The request timed out} 超时时间设置在哪里？ ...也许我应该让它更长一点以防万一？
通过设置[request setNumberOfTimesToRetryOnTimeout: 2]解决了；非常感谢！ :)
+ (void)setDefaultTimeOutSeconds:(NSTimeInterval)newTimeOutSeconds; - 这是一个类方法，所以在创建任何实例之前设置它。默认值为 10 秒。
