Question

Our iPhone app code currently uses NSURLConnection sendSynchronousRequest and that works fine except we need more visibility into the connection progress and caching so we’re moving to an async NSURLConnection.

What’s the simplest way to wait for the async code to complete? Wrap it in a NSOperation/NSOperationQueue, performSelector…, or what?

Thanks.

I’m answering this in case anyone else bumps into the issue in the future. Apple’s URLCache sample code is a fine example of how this is done. You can find it at:

• iOS Developer Library – URLCache

As John points out in the comment above – don’t block/wait – notify.
