I want to send an NSNotification
from this method (when the UIButton
is clicked) in my AppDelegate.m:
- (void)alertView:(UIAlertView *)alertView
clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 0){
//cancel clicked ...do your action
// HERE
}
}
..and receive it in one of my UIViewControllers
. How can I do that?
EDIT WITH MORE INFO: I am making an alarm app, and when the user presses the UIButton
, I want to stop the alarm. I figured that NSNotifications
is the only way to get information from my AppDelegate.m file to a ViewController.m file?
You should to register your receiver object to accept some messages sent from Notification Center.
Suppose you have Obj A which controls your alarm, and value "stopAlarm" is the message which can stop alarm. You should create an observer for a "stopAlarm" message.
You can do, with:
Now, you should create a method controller that manages this messages:
Finally, you can send the message "stopAlarm" when you want in the code with:
I Hope this may help.
EDIT:
When your UIViewController are unloaded or when app terminate, you should call:
for stop observing. That's all.
Thanks to Hot licks for correction.
