iOSでEKEventを更新または編集し、識別子を使ってネイティブカレンダーに保存する方法は？

Question

私はすべてのストアイベントをフェッチするために私のアプリでEKEventを使用しています。特定のイベントを識別子で編集し、既存のものに再保存したいのですが、何をすべきですか？

EKEventStore *store = [EKEventStore new]; 
    EKEvent *event = [EKEvent eventWithEventStore:store]; 

    event.title = @"abc"; 
    event.notes= @"this is updated notes"; 

    event.calendar = [store defaultCalendarForNewEvents]; 
    NSError *err = nil; 

    [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err]; 

このコードはイベントを保存するために使用していますが、特定のイベントのみを更新するための識別子を渡す場所はどこですか？

Answer 1

ようにするには、データベース内のイベント識別子を保存する必要があります後でこのイベントを使用してイベントを更新または削除することができます。イベントの作成後：

[store saveEvent:event span:EKSpanThisEvent commit:YES error:&err]; 

event.eventIdentifierにアクセスできます。データベースに保存します。特定のイベントを編集する場合は、保存されているIDを使用してそのイベントを取得してください：

-(void)updateNotification:(NSMutableDictionary *) info 
{ 
    EKEventStore *eventStore = [[EKEventStore alloc] init]; 
    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) 
    { 
     if (!granted) 
     { 
      dispatch_async(dispatch_get_main_queue(), ^{ 

       UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Cannot access Calendar" message:@"Please give the permission to add task in calendar from iOS > Settings > Privacy > Calendars" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; 
       [alert show]; 

      }); 
      return; 
     } 

     if (error) 
     { 
      NSLog(@"%@", error); 
     } 

     //this is event ID you saved in DB. now you want to edit that event 
     EKEvent *event = [eventStore eventWithIdentifier:info[@"eventID"]]; 

     if(event) { 

//You have your valid event. Modify as per your need. 

      event.title  = [info valueForKey:@"title"]; 
      event.notes  = [info valueForKey:@"description"]; 
      event.startDate = [info objectForKey:@"date"]; 
      event.endDate = [[NSDate alloc] initWithTimeInterval:3600*24 sinceDate:event.startDate]; 
      event.calendar = eventStore.defaultCalendarForNewEvents; 

      [eventStore saveEvent:event span:EKSpanThisEvent commit:YES error:&error]; 

     } 

    }]; 
} 

希望します。お気軽に質問してください。

これは、すべてのイベントを取得するためのコードです。 Ref。 アップルのデモプロジェクト

- (NSMutableArray *)fetchEvents{ 

NSDate *startDate = [NSDate date]; 

//Create the end date components 
NSDateComponents *tomorrowDateComponents = [[NSDateComponents alloc] init]; 
tomorrowDateComponents.day = 1; 

NSDate *endDate = [[NSCalendar currentCalendar] dateByAddingComponents:tomorrowDateComponents 
                   toDate:startDate 
                   options:0]; 
// We will only search the default calendar for our events 
NSArray *calendarArray = @[self.defaultCalendar]; 

// Create the predicate 
NSPredicate *predicate = [self.eventStore predicateForEventsWithStartDate:startDate 
                    endDate:endDate 
                   calendars:calendarArray]; 

// Fetch all events that match the predicate 
NSMutableArray *events = [NSMutableArray arrayWithArray:[self.eventStore eventsMatchingPredicate:predicate]]; 

return events; 

}
