iPhone锁定和解锁时，ASIHTTPREQUEST给出错误（1）

Question

I am using ASIHTTPREQUEST to do asynchronous network connections in my app. For the most part it works great. However, if I am running a connection, and lock the phone (but leave the app open), and the unlock it, I get the following error on my connections:

ErrorDomain=ASIHTTPREQUESTErrorDomain Code=1 "The operation could not be completed." (ASIHTTPREQUESTErrorDomain error 1.)

How can I stop this from happening, or even make the HTTP requests continue to work even if the phone has been locked or the screen shuts off?

Answer 1

Start a background task with UIApplication 's beginBackgroundTaskWithExpirationHandler: method before initiating the request. End the background task when the request returns with success or failure and you have processed the data from the request.
