本文介绍了NSURLSession：后台上传然后调用服务api的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图使用新的ios7后台传输api将一些照片上传到服务器。它现在发生的是 1）我们将字节上传到s3 2）调用服务api来完成上传

I was trying to use the new ios7 background transfer api to upload some photos to a server. what it happened now is 1) we upload the bytes to s3 2) call a service api to 'complete' the upload

我看了在这个文档和似乎背景NSURLSession不支持'数据'任务。这是否意味着我在实际上传完成后无法在后台执行第2步？

i looked at this doc and it seems background NSURLSession doesn't support 'data' task. does that mean i can't do the step 2 in background after the actual upload is done?
