推荐答案

我想你的意思是 Web API 调用，比如谷歌的地理服务.为此，您需要使用 NSURLConnection 进行调用.这样，您可以随时使用 [取消连接] 取消通话.

I suppose you mean a web API call, like google's geoservices. To do this, you will need to make the call using a NSURLConnection. This way, you can cancel a call anytime using [connection cancel].

试试这个教程:http://mobileorchard.com/tutorial-json-over-http-on-the-iphone/ 它用于 JSON api 调用.如果您需要另一个 API，只需从通过 HTTP 获取 JSON"开始阅读，他们就会在那里设置一个 NSURLConnection.如果您保留此连接直到完成，您将可以随时拨打 [取消连接] 电话.

Try this tutorial: http://mobileorchard.com/tutorial-json-over-http-on-the-iphone/ It's meant for a JSON api call. If you need another API, just start reading from 'fetching JSON over HTTP', there they set up a NSURLConnection. If you retain this connection until it's done, you will be able to make the [connection cancel] call at anytime.

使用 UIApplicationDelegate 可以检测应用进入后台.

Using the UIApplicationDelegate, you can detect the app entering the background.
