Mac Forum / Programming / Mac Programming / June 2005How to wait for Notification
Hi, One more question. I'm performing a search function in PDF file. I use didFind delegate to proccess results. The problem is to make program wait for the search to be completed. The search method I'm using is posting notification documentDidEndDocumentFind, but I have no idea how to use it in this case. Any suggestions are appreciated. Thanks a lot. * posted via http://www.mymac.ws * please report abuse to http://xinbox.com/mymac > Hi, > [quoted text clipped - 4 lines] > no idea how to use it in this case.

That's what I.m trying to do, but wierd it seems that the notifications are late, while control is already at the loop's next cicle. * posted via http://www.mymac.ws * please report abuse to http://xinbox.com/mymac > > Just return control back to the event loop and let your app continue > > to [quoted text clipped - 5 lines] > notifications are late, while control is already at the loop's next > cicle. You mean, on the next pass through the event loop? That's normal. Notifications are delivered using the event loop, but there's no guarantee of them arriving at any particular pass through the loop.

That's the entire point of using a notification in this case. The search won't complete instantly. By using a notification, your application can continue to be responsive in the user until it finishes. |
