Send local notification at a certain time of the day - ios

Question

I want to get a random string from an array and then display this everyday at 7am.
Here is the code in my AppDelegate.m
-(void)applicationDidEnterBackground:(UIApplication *)application
{
QuoteTableViewController *quoteVC;
int randomlyGeneratedNumber;
randomlyGeneratedNumber =arc4random()%[quoteVC.arrayOfOurQuotes count];
NSString *stringOfTheDay = [[NSString alloc] init];
stringOfTheDay = [quoteVC.arrayOfOurQuotes objectAtIndex:randomlyGeneratedNumber];
NSLog(#"%#",stringOfTheDay);
NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDateComponents *componentsForReferenceDate = [calendar components:(NSCalendarUnitDay | NSCalendarUnitYear | NSCalendarUnitMonth ) fromDate:[NSDate date]];
[componentsForReferenceDate setDay:9];
[componentsForReferenceDate setMonth:11];
[componentsForReferenceDate setYear:2012];
NSDate *referenceDate = [calendar dateFromComponents:componentsForReferenceDate];
NSDateComponents *componentsForFireDate = [calendar components:(NSCalendarUnitYear | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond ) fromDate: referenceDate];
[componentsForFireDate setHour:7];
[componentsForFireDate setMinute:0];
[componentsForFireDate setSecond:0];
NSDate *fireDateOfNotification = [calendar dateFromComponents:componentsForFireDate];
// Create the notification
UILocalNotification *notification = [[UILocalNotification alloc] init];
if (notification) {
notification.fireDate = fireDateOfNotification;
notification.timeZone = [NSTimeZone localTimeZone];
notification.repeatInterval = 0;
notification.alertBody = [NSString stringWithFormat:stringOfTheDay];
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
}
There is a error at this line when i run the code
randomlyGeneratedNumber =arc4random()%[quoteVC.arrayOfOurQuotes count];
There is an array in my other View Controller. I did import the view controller.
EDIT :
Array has strings inside but when imported into app delegate it becomes 0. How to fix this?

Answer 1

You need to implement 'arrayOfOurQuotes' as a property of your App delegate instead of the view controller. The view controller and therefore your array will not be around anymore when the view is gone - which is obviously the case if you have already entered the background.
