iphone - ASINetworkQueue setQueueDidFinishSelector 选择器提前结束？

Question

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 个项目处随机停止，不确定具体原因，但选择器被调用得太早虽然并不是所有的请求都结束了。

我所做的唯一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。

我按如下方式配置选择器:

[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。

您是否尝试过将 setShouldCancelAllRequestsOnFailure: 设置为 NO ？队列的默认行为是在任何单个请求失败时取消所有剩余请求。

可能是请求失败(由于某种原因)，导致您的队列过早完成。
