问题描述
我正在寻找一种为CFHTTP请求添加超时的方法。似乎应该有 CFHTTPMessage 或 CFReadStream 对象的功能，但我找不到它。我是否必须在运行循环中滚动自己的计时器？ （如果是这样，任何代码？）
I am looking for a way to add a timeout to a CFHTTP request. It seems like there should be a feature of the CFHTTPMessage or the CFReadStream object, but I can't find it. Do I have to roll my own timer on the run loop or something? (if so, any code for this?)
谢谢！
推荐答案
NSURLRequest 中包含的大部分功能。您可以使用 NSURLRequest 的 requestWithURL指定超时：cachePolicy：timeoutInterval：
Update: ASIHTTPRequest is outdated and no longer maintained. I would now recommend either using Apple's built in NSURLConnection. NSURLConnection has a very small asynchronous API with most of the functionality contained in NSURLRequest. you can specify your timeout using NSURLRequest's requestWithURL:cachePolicy:timeoutInterval:
除非你有使用CFHTTPMessage的特殊原因，否则我建议使用更高级别的课程，例如，为您提供更多易用性，包括超时。
Unless you have a special reason for using CFHTTPMessage I'd recommend using a higher level class such as ASIHTTPRequest which gives you added ease of use including timeouts.
