Question

我有一个OUP记录类型，它对.DeleteSelf记录类型有一个OU引用。

如果我只是设置无条件订阅，则有效：

let subscriptionOUP = CKSubscription(recordType: "OUP", predicate:NSPredicate(value: true), subscriptionID: "oup", options: .FiresOnRecordUpdate)

但条件方式不：

let ekf = "oup-\(ou.recordID)"
let pr = NSPredicate(format: "ou = %@", CKReference(recordID: CKRecordID(recordName: organizationUser.recordID), action: .DeleteSelf))
let subscriptionOUP = CKSubscription(recordType: "OUP", predicate:pr, subscriptionID: ekf, options: .FiresOnRecordUpdate)
println("\(pr) \(ekf)")

终端内容：

ou == <CKReference: 0x1558d3d0;51D56239-D68C-4E12-BD23-E4DCEF5721B7:(_defaultZone:__defaultOwner__)> 

oup-51D56239-D68C-4E12-BD23-E4DCEF5721B7

我的谓词或订阅ID有什么问题？

Answer 1

subscriptionID字符串太长。

当你这样减少它时，它会起作用：

let ekf = "oup-\((organizationUser.recordID as NSString).substringToIndex(7))"

条件CKSubscription不会触发通知
