    //create a new RecordType
    CKRecordID *wellKnownID = [[CKRecordID alloc] initWithRecordName:@"1"];
    CKRecord *poi = [[CKRecord alloc] initWithRecordType:@"POI" recordID:wellKnownID];
    
    //create and set record instance properties
    poi[@"title"] = @"Sample point of interest";
    poi[@"description"] = @"My favorite point of interest";
    poi[@"address"] = @"123 Main Street, Endor";
    poi[@"location"] = [[CLLocation alloc] initWithLatitude:47.605024 longitude:-122.335274];
    
    //get the PublicDatabase from the Container for this app
    CKDatabase *publicDatabase = [[CKContainer defaultContainer] publicCloudDatabase];
    
    //save the record to the target database
    [publicDatabase saveRecord:poi completionHandler:^(CKRecord *record, NSError *error) {
        
        //handle save error
        if(error) {
            
            NSLog(@"Uh oh, there was an error saving ... %@", error);
        
        //handle successful save
        } else {
            
            NSLog(@"Saved successfully");
            NSLog(@"Title: %@", record[@"title"]);
            NSLog(@"Description: %@", record[@"description"]);
            NSLog(@"Address: %@", record[@"address"]);
            NSLog(@"Location: %@", record[@"location"]);
        }
    }];
