Eu tenho um cache de agendamento armazenado em umNSDictionary.

Para o exemplo abaixo, tenho um horário de agendamento de13 de janeiro de 20120 14:00 e13 de janeiro de 2012 14:05. Como posso adicionar os dois a uma fila para disparar por conta própria?

Crie o cache de agendamento:

-(void) buildScheduleCache
{  
    NSCalendarDate *now = [NSCalendarDate calendarDate];

    NSFileManager *manager = [[NSFileManager defaultManager] autorelease];
    path = @"/var/mobile/Library/MobileProfiles/Custom Profiles";
    theProfiles = [manager directoryContentsAtPath:path];

    myPrimaryinfo = [[NSMutableArray arrayWithCapacity:6] retain];
    keys = [NSArray arrayWithObjects:@"Profile",@"MPSYear",@"MPSMonth",@"MPSDay",@"MPSHour",@"MPSMinute",nil];

    for (NSString *profile in theProfiles) 
    {
        plistDict = [[[NSMutableDictionary alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/%@",path,profile]] autorelease];

        [myPrimaryinfo addObject:[NSDictionary dictionaryWithObjects:
                                  [NSArray arrayWithObjects:
                                   [NSString stringWithFormat:@"%@",profile], 
                                   [NSString stringWithFormat:@"%@",[plistDict objectForKey:@"MPSYear"]], 
                                   [NSString stringWithFormat:@"%@",[plistDict objectForKey:@"MPSMonth"]], 
                                   [NSString stringWithFormat:@"%@",[plistDict objectForKey:@"MPSDay"]], 
                                   [NSString stringWithFormat:@"%@",[plistDict objectForKey:@"MPSHour"]], 
                                   [NSString stringWithFormat:@"%@",[plistDict objectForKey:@"MPSMinute"]],
                                   nil]forKeys:keys]];

        profileSched =
        [NSCalendarDate dateWithYear:[plistDict objectForKey:@"MPSYear"]
                               month:[plistDict objectForKey:@"MPSMonth"]
                                 day:[plistDict objectForKey:@"MPSDay"]
                                hour:[plistDict objectForKey:@"MPSHour"]
                              minute:[plistDict objectForKey:@"MPSMinute"]
                              second:01
                            timeZone:[now timeZone]];

        [self rescheduleTimer];
    }

    NSString *testPath = @"/var/mobile/Library/MobileProfiles/Schedules.plist";
    [myPrimaryinfo writeToFile:testPath atomically:YES];
}

Programar o evento:

-(void) scheduleProfiles
{
    NSFileManager *manager = [[NSFileManager defaultManager] autorelease];
    path = @"/var/mobile/Library/WrightsCS/MobileProfiles/Custom Profiles";
    theProfiles = [manager contentsOfDirectoryAtPath:path error:nil];

    for (NSString *profile in theProfiles) 
    {
        NSMutableDictionary * plistDict = [[[NSMutableDictionary alloc] initWithContentsOfFile:[NSString stringWithFormat:@"%@/%@",path,profile]] autorelease];

        profileSched =
        [NSCalendarDate dateWithYear:[[plistDict objectForKey:@"MPSYear"] intValue]
                               month:[[plistDict objectForKey:@"MPSMonth"] intValue]
                                 day:[[plistDict objectForKey:@"MPSDay"] intValue]
                                hour:[[plistDict objectForKey:@"MPSHour"] intValue]
                              minute:[[plistDict objectForKey:@"MPSMinute"] intValue]
                              second:01
                            timeZone:[NSTimeZone localTimeZone]];


            NSLog(@"DATE: %@      SCHEDULE: %@      PROFILE: %@",[NSDate date],profileSched,profile);
        if([NSDate date] < profileSched)
        {
            NSLog(@"IGNORING PROFILE: %@     WITH SCHEDULE: %@",profile,profileSched);
        }else{
            //Create the timer from the Cached Array
            schedTimer = [[NSTimer alloc] initWithFireDate:profileSched //[NSDate dateWithTimeIntervalSinceNow: 10]
                                                  interval:0.1f
                                                    target:self
                                                  selector:@selector(fireCustomProfile:)
                                                  userInfo:profile
                                                   repeats:NO];//[[plistDict objectForKey:@"MPSRepeat"] boolValue]];

            MLogString(@"Scheduling Profile: %@",profile);
            [[NSRunLoop currentRunLoop] addTimer:schedTimer forMode:NSDefaultRunLoopMode];
        }
    }
}

Dispare o evento:

-(void)fireCustomProfile:(NSTimer *)timer
{   
    if([[NSDate date] earlierDate:[schedTimer fireDate]])
    {
        NSLog(@"Ignoring Profile: %@",[schedTimer userInfo]);
        return;
    }

    notify_post("com.wrightscs.MobileProfiles.setCustomProfile");
}
