Question

Hi I working on a reminder application.

I need to display a reminder alert after some particular time.

But not at the time we have set in date picker.

Just like I have a button ‘Remind in 10 Mins’

}

When user press the button , After 10 mins it needs to display an alert.

You need to use UILocalNotification for this Function
Code is look like

UIApplication* app = [UIApplication sharedApplication];
        UILocalNotification* notifyAlarm = [[UILocalNotification alloc] init];

        NSDate *date1=[fire dateByAddingTimeInterval:60];
        notifyAlarm.fireDate = date1;
        notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
        //notifyAlarm.timeZone = [NSTimeZone defaultTimeZone];
        notifyAlarm.repeatInterval =NSWeekCalendarUnit ;
        notifyAlarm.soundName =soundString;
        notifyAlarm.alertBody =snoozeBody;
        notifyAlarm.userInfo=snoozeDict;
        //notifyAlarm.alertLaunchImage=@"in.png";
        [app scheduleLocalNotification:notifyAlarm];
