NSPredicate CKReference不是用户ID

Question

我正在尝试创建一个云工具包nspredicate，它将返回forSale(Int) == 1和ownerRecord(CKRefereance) !=当前用户记录的所有项。这就是我所拥有的：

let Query = CKQuery(recordType: "Item", predicate: NSPredicate(format: "ownerRecord.recordID != %@, forSale = 1", [NSUserDefaults.standardUserDefaults().objectForKey("cloudkitUserReccordID") as! String]))

Answer 1

您需要查询引用，而不是recordId字符串。然后，你可能会看起来像这样：

let ownerId = NSUserDefaults.standardUserDefaults().objectForKey("cloudkitUserReccordID") as! String
let ownerRef = CKReference(recordID: CKRecordID(recordName: ownerId), action: CKReferenceAction.None)
let predicate = NSPredicate(format: "ownerRecord != %@, forSale = 1", ownerRef)
let query = CKQuery(recordType: "Item", predicate: predicate))
