NSURLConnection超时？ [英] NSURLConnection timeout?

问题描述

我正在将NSURLConnection与委托人一起使用。

I'm using this NSURLConnection with delegates.

nsconnection = [[NSURLConnection alloc] initWithRequest:request
    delegate:self startImmediately:YES];

问题是网站根本没有回复。没什么，只是在浏览器中旋转空白页面，没有失败。在我的代表中，我处理失败，但当网站没有响应时，代表不会被调用。关于如何超时连接的任何想法？

Problem is the website doesn't respond at all. Nothing, just spins in browser with blank page, no failure. In my delegates, I handle the failure, but when the site doesn't respond the delegates don't get called. Any ideas on how to timeout the connection?

推荐答案

您可以在 NSURLRequest中指定超时对象。一种方法是通过 requestWithURL来构建它。 ：cachePolicy：timeoutInterval： 方法。 （如果您不想担心该部分，可以传入默认的 NSURLRequestUseProtocolCachePolicy cachePolicy参数。）超时是一个以秒为单位的浮点值，基本上是iPhone SDK中的所有时间间隔。

You can specify a timeout in your NSURLRequest object. One way to do this is to construct it via the requestWithURL:cachePolicy:timeoutInterval: method. (You can pass in the default NSURLRequestUseProtocolCachePolicy cachePolicy parameter if you don't want to worry about that part.) The timeout is a floating-point value in seconds, as are basically all time intervals in the iPhone SDK.

还要确保设置 NSURLConnection 的委托并响应 connection：didFailWithError： 方法。连接总是在连接完成时调用此方法或 connectionDidFinishLoading：。

Also make sure your NSURLConnection's delegate is set and responds to the connection:didFailWithError: method. A connection always calls either this method or connectionDidFinishLoading: upon connection completion.
