Hi,
I have defined class (say, Download) that uses NSURLConnection to
download something from internet. My application is Cocoa with UI. I
want to call:
[Download cancel]
and wait for notification from this class once user quits application.
Reasoning: my Download class should cancel connection and perform some
operations before object can be released in program. Thus I can not
simply deallocate Download instance in dealloc method.
So, the idea is: instead of calling [myDownload cancel] from dealloc
method delay application quit until all steps are completed in
Download. Thus call [myDownload cancel] and wait for Notification say
DownloadCanceled. Only then deallocate object.
Is there any way to figure out when user initiated quit application?
How to delay it?
I think there should be something pretty much similar to awakeFromNib
but called at the very end upon application quit.
Thanks.
