cloudkit

问题 Is there a straightforward way to share private data between two or more users using CloudKit? Public and private date are obvious, but there doesn't seem to be a way to allow a group of users to organize their own silo to share data amongst themselves without making it available to all the other users of the system and to the app developer. I have an academic collaboration app in mind but the simplest example would be private messaging between two users. I guess one could try to build a

问题 I want the users' location to be updated in cloudkit but my code just save a new record every time. How can the existing record be modified or replaced by the new one? func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { let location = locations.last let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude) let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta

问题 UPDATE notification stopped working. What workaround do you have, until Apple figures out something? CKFetchNotificationChangesOperation sometimes does not return UPDATE, DELETE notifications CloudKit push notifications on record update stopped working https://forums.developer.apple.com/thread/7288 My quick fix, that in every minute, and when user triggers UIRefreshControl , then I downloading all the records that were modified since the last update. It works. But I have a better idea in my

问题 I try to use CloudKit subscriptions in my app, but didReceiveRemoteNotification not get triggered. I saved CKSubscription to CloudKit . To be sure they exists, when app starts, I plot them out, like: <CKSubscription: 0x15576310; ; Query Subscription: recordType=DailyVote, predicate=TRUEPREDICATE, subscriptionOptions=7, subscriptionID=1FA456A6-9BA5-411D-97B9-1EB57121A5D0, zoneID=(null)> predicate: TRUEPREDICATE subscriptionType: (Enum Value) subscriptionOptions: C.CKSubscriptionOptions I try

问题 I'm studying the new CKShare that Apple released this year and I have some questions with it. I was trying to follow the WWDC's "What's new in CloudKit" video but part of the code isn't working anymore in Xcode. What I'm trying to do is: the user will enter his name and phone and after clicking a UIButton , will share with a specific person. Here is the code: class ViewController: UIViewController, UICloudSharingControllerDelegate { @IBOutlet weak var nome: UITextField! @IBOutlet weak var

问题 I have plenty of record manually preloaded to CloudKit but in the development environment. When I deployed development environment, records were not moved into production environment. It is really annoying. Any easy way to move records? 回答1: There is no easy way to migrate your records. You cannot link an app both to production and to development. The only workaround is downloading all records from development and storing those records in a file and then switch to production and upload the

问题 I am trying to make an app in which every user would have a personal avatar, a nickname and so on. I don't know how to access the user's account on cloudkit. My solution would be to retrieve user's AppleID, query Cloudkit and modify the user's attribute... But I guess there should be a better way to do it. Isn't their something like NSUserDefault but for cloudkit? 回答1: You first have to find out what the current loged in userId is. You can do that by executing the

问题 CKFetchRecordChangesOperation in the simplified method below does not return any records. I call it with a nil, to initially get all the records, but it only returns the server token. However, if I use CKQuery I get all the records correctly. What am I missing? func fetchChangedRecords(token :CKServerChangeToken?) { println("\(__FUNCTION__) token: \(token)") let zoneID = CKRecordZoneID(zoneName: kMyZone, ownerName: CKOwnerDefaultName) var op = CKFetchRecordChangesOperation(recordZoneID:

问题 Say I have 2 entities in my CloudKit database: - Album - (NSString) title - Photo - (NSString) name - (CKRefrence) album Photos have a CKReference to an Album. This means that 1 album can have many photos (as expected). I have a screen where I want to display all albums, and how many photos are in each album. What is the best way to query for this? If I query for Albums right now, each album knows nothing about its photos. 回答1: For each of the album object anAlbum, you would form your

问题 I am working on a CloudKit backed app with a Users record type that has a "following" reference list attribute. I am trying to construct a query to get every user that is following a specified user (i.e. those users in which the specified user appears as an entry in the following reference list). I am currently trying to construct my NSPredicate for the CKQuery as such: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"%@ IN following", [[CKReference alloc] initWithRecordID
