如何获取CKShare？

Question

我可以通过单击共享生成的链接生成一个共享并正常获取它，但一旦我关闭应用程序并再次打开它，它就全部消失了！我想做的是在没有链接的情况下访问共享.通过打开应用程序，在第一次被接受的共享中加载内容。有人知道怎么做吗？

提前感谢

这样啊，原来是这么回事!首先，您需要获取所需共享的CKRecordZone。

let sharedData = CKContainer.default().sharedCloudDatabase
    sharedData.fetchAllRecordZones { (recordZone, error) in
        if error != nil {
            print(error?.localizedDescription)
        }
        if let recordZones = recordZone {
            //Here you'll have an array of CKRecordZone that is in your SharedDB
        }
    }

现在，您只需要像对常规的CKShare一样获取CKRecord：

func asdasdasa(id: CKRecordZoneID) {

    ctUsers = [CKRecord]()
    let sharedData = CKContainer.default().sharedCloudDatabase
    let predicate = NSPredicate(format: "TRUEPREDICATE")
    let query = CKQuery(recordType: "Elder", predicate: predicate)

    sharedData.perform(query, inZoneWith: id) { results, error in
        if let error = error {
            DispatchQueue.main.async {
                print("Cloud Query Error - Fetch Establishments: \(error)")
            }
            return
        }
        if let users = results {
            print(results)
            self.ctUsers = users
            print("How many shares in cloud: \(self.ctUsers.count)")
            if self.ctUsers.count != 0 {
                // Here you'll your Shared CKRecords!
            }
            else {
                print("No shares found")
            }
        }
    }
}
