Why isn't my didEndSelector in my NSAlert being called?

Question

I can't figure out why my didEndSelector isn't being called. Any ideas?

 - (void) showMonitorAlertIfNeeded {

    if (! self.monitorAlert && [self isHideMonitorAlert]) {

        self.monitorAlert = [MMAlertController monitorAlert];

        [[self.monitorAlert window] setTitle: [self applicationName]];

        [self.monitorAlert beginSheetModalForWindow: [NSApp keyWindow] 
                                    modalDelegate: self 
                                   didEndSelector: @selector(monitorAlertDidEnd:returnCode:contextInfo:) 
                                      contextInfo: nil];


        [[self.monitorAlert window] setLevel: NSScreenSaverWindowLevel];

    }
}


- (void) monitorAlertDidEnd: (NSAlert *) alert returnCode: (NSInteger) code contextInfo: (id) contextInfo {

    switch (code) {
        case NSAlertFirstButtonReturn:{
        }
            NSLog(@"FIRST BUTTON PRESSED");
            break;

        case NSAlertSecondButtonReturn:{ // don't show again.
            NSLog(@"SECOND BUTTON PRESSED");
            [[NSApp delegate]setIsHideMonitorAlert:NO];
        }

        break;

        default:
            break;
    }
}

Hmm, just tried it actually. It's being called, any idea why my switch statements aren't being called? — aroooo, Jun 28 '12 at 00:05

If [MMAlertController monitorAlert] returns an NSAlert that was created with alertWithMessageText:defaultButton:alternateButton:otherButton:informativeTextW‌ithFormat: then your switch should actually contain NSAlertDefaultReturn and NSAlertAlternateReturn. (If it was created in any other way then your original switch values are correct.)

Try to insert this line just before the switch:

NSLog(@"code: %ld", code);

The first button pressed and second button pressed don't get logged. If I put it outside of the switch statement it does. – aroooo Jun 28 '12 at 00:19
What I meant to know was if you logged the value of the code outside the switch. – Bruno Ferreira Jun 28 '12 at 00:21
Yes, anything in showMonitorAlertIfNeeded gets logged, anything outside of the switch(code){} gets logged in monitorAlertDidEnd – aroooo Jun 28 '12 at 00:28
Edit: Nevermind, that's because we were logging %@ and not %d, I'm gonna try and create a switch with the specific numbers instead. – aroooo Jun 28 '12 at 00:41
In my application I have a similar callback function for my NSAlert, the only diference I can see is that instead of code my parameter is called returnCode, but I don't it should make a diference. – Bruno Ferreira Jun 28 '12 at 00:51

Why isn't my didEndSelector in my NSAlert being called?
