iOS Alarm Clock

Question

I have created a simple alarm notification App through which I can get real time, set alarm on or off, and play a single tone audio. But I need to play a sound which should start with a class VOID.

Below is the code:

To get and start alarm notification:

- (void)viewDidLoad {

    [super viewDidLoad];

    dateTimerPicker.date = [NSDate date];

}

- (void)presentMessage:(NSString *)message {

    UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:@"Hello!"
                          message:message
                          delegate:nil
                          cancelButtonTitle:@"OK"
                          otherButtonTitles: nil];
    [alert show];

}

- (void)scheduleLocalNotificationWithDate:(NSDate *)fireDate {

    UILocalNotification *notification = [[UILocalNotification alloc]init];
    notification.fireDate = fireDate;
    notification.alertBody = @"Time to wake up!!";
    notification.soundName = @"PhoneOld.mp3";
    [self playPause];

    [[UIApplication sharedApplication] scheduleLocalNotification:notification];

}

- (IBAction)alarmSetOn:(id)sender{

    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    dateFormatter.timeZone = [NSTimeZone defaultTimeZone];
    dateFormatter.timeStyle = NSDateFormatterShortStyle;
    dateFormatter.dateStyle = NSDateFormatterShortStyle;

    NSString *dateTimeString = [dateFormatter stringFromDate:dateTimerPicker.date];
    NSLog(@"Alarm Set: %@", dateTimeString);


    [self scheduleLocalNotificationWithDate:dateTimerPicker.date];
    [self presentMessage:@"Alarm ON!"];


}

- (IBAction)alarmSetOff:(id)sender {
    NSLog(@"Alarm Off");

    [[UIApplication sharedApplication] cancelAllLocalNotifications];
    [self presentMessage:@"Alarm OFF!"];
}

This is my VOID:

- (void)playPause {

    RADAppDelegate *appDelegate = (RADAppDelegate *)[[UIApplication sharedApplication] delegate];

    if (appDelegate.radiosound == 0){

        [appDelegate.radiosound play];

    } else {

        [appDelegate.radiosound pause];

    }

}

How can I set the alarm to start playing the radiosound if is rated 0, like a:

notification.soundName = [self playPause]; 

But I know this is a NSString.

You don't need to assign a sound name to scheduled notification, just invoke the playPause method and get the name of sound file from notification, as shown below and just assign it to NSString and set property to it in appDelegate and access it to play that file.

AppDelegate.h

@property (nonatomic,strong) NSString *nsStr_soundFile;

AppDelegate.m

@synthesize nsStr_soundFile;

- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification {


//Give call to play sound method.

self.nsStr_soundFile=notification.soundName;
    VOID *obj=[VOID alloc]init];
        [obj playPause];

}
