EKEventStore - 該事件不屬於該事件存儲區

Question

我無法保存我的提醒/事件。但我已被授予使用提醒的權限（我檢查了設置）。我已經打印出錯誤，它說That event does not belong to that event store.這是我的代碼;

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 

    self.eventStore =[[EKEventStore alloc] init]; 
    self.eventStoreAccessGranted = NO; 
    [self.eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) { 
     self.eventStoreAccessGranted = granted; 
     if (!granted) { 
      NSLog(@"User has not granted permission"); 
     } 
    }]; 

} 



- (IBAction)setAReminder:(id)sender { 

    if (!self.eventStoreAccessGranted) { 
     NSLog(@"Reminder is no"); 
     return; 
    } 
    NSLog(@"Reminder is YES"); 
    EKReminder * newReminder = [[EKReminder alloc] init]; 
    newReminder.title = @"Pick up the kids"; 
    newReminder.calendar = [self.eventStore defaultCalendarForNewReminders]; 


    NSDate *now = [NSDate date]; 
    NSDate *alarmDate = [now dateByAddingTimeInterval:120]; 
    EKAlarm * ourAlarm = [EKAlarm alarmWithAbsoluteDate:alarmDate]; 

    [newReminder addAlarm:ourAlarm]; 
    NSError *error = nil; 

    [self.eventStore saveReminder:newReminder commit:YES error:&error]; 
    NSLog(@"Event %@",[error localizedDescription]); 
} 

哪裏有問題的建議？

我改變了我的代碼，並且它工作正常。

-(IBAction)setAReminder:(id)sender { 

    if (self.eventStore == nil) 
    { 
     self.eventStore = [[EKEventStore alloc]init]; 

     [self.eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) { 

     if (!granted) 
      NSLog(@"Access to store not granted"); 
     }]; 
    } 

    if (self.eventStore != nil) 
     [self createReminder]; 

} 

-(void)createReminder 
{ 
    EKReminder *reminder = [EKReminder 
         reminderWithEventStore:self.eventStore]; 

    reminder.title = @"Test"; 

    reminder.calendar = [_eventStore defaultCalendarForNewReminders]; 

    NSDate *date = [NSDate date]; 

    EKAlarm *alarm = [EKAlarm alarmWithAbsoluteDate:[date dateByAddingTimeInterval:120]]; 

    [reminder addAlarm:alarm]; 

    NSError *error = nil; 

    [_eventStore saveReminder:reminder commit:YES error:&error]; 

    if (error) 
    NSLog(@"error = %@", error); 

}
