In my app, I present the user with an MFMessageViewController, and after 10 seconds, I auto-dismiss it by calling
[self.presentedViewController performSelector:@selector(dismissModalViewControllerAnimated:)
withObject:[NSNumber numberWithBool:YES] afterDelay:10];
The problem is, if the user has begun using the MFM (i.e. adding a recipient by either typing or hitting the plus sign or editing the body), I have no way to cancel this call. I know that I could call
[NSObject cancelPreviousPerformRequestsWithTarget:self.presentedViewController
selector:@selector(dismissModalViewControllerAnimated:) object:[NSNumber
numberWithBool:YES]];
but I have no way of knowing when the user has started editing the MFM in the ways described above. Is there a solution to this?
I suggest that you leave the dismissal of the MFMessageViewController to the user. The user has invoked it & he would be the best judge when to dismiss it. In this case auto-dismiss I think is not safe & might piss off the user in some cases.
Its just not intuitive. Why would you want to dismiss in 10 secs? Just let it be.
