Edit Question
Title
Body
I would like to start a server request, you can cancel. My idea is to start the request in a thread so that the user interface does not freeze. So you can kill the whole thread including the request with a click on a "Cancel"-button. With Android it works: the server request gets started in a "AsyncTask" and in the "onReturn()"-method I can react as soon as the server request finish. How can I implement this using Objective-C on iOS? My first attempt was a "NSInvocationOperation". You can cancel the operation, but it's difficult to handle when a request is completed and results are available. I think NSInvocationOperation is not the solution for my issue. The would you recommend to me? Is NSThread the right choice for me? Thank you very much!
