我正在用xcode 7 beta 5开发一个应用程序。当我在iPhone
6上运行我的应用程序，并且如果我的iPhone以wifi模式工作时，我尝试将其连接到CloudKit，就可以显示我的所有数据。但是，如果我的iPhone以LTE模式工作，则看不到任何数据。有谁知道如何做到这一点？

    func getRecordsFromCloud() {

    lavori = []

    /

    let _cloudContainer = CKContainer.defaultContainer()  
    let publicDatabase = CKContainer.defaultContainer().publicCloudDatabase

    /

    let predicate = NSPredicate(value: true)  
    let query = CKQuery(recordType: "Lavori", predicate: predicate)

    /

    let queryOperation = CKQueryOperation(query: query)

    queryOperation.desiredKeys = ["image","name"]  
    queryOperation.queuePriority = .VeryHigh  
    queryOperation.resultsLimit = 50

    queryOperation.recordFetchedBlock = { (record:CKRecord) -> Void in

        let lavoriRecord = record

        self.lavori.append(lavoriRecord)



    }

    queryOperation.queryCompletionBlock = { (cursor:CKQueryCursor?, error:NSError?) -> Void in

        if (error != nil) {

            print("Failed to get data from iCloud - \(error!.localizedDescription)")

        }  
        else {

            print("Successfully retrieve the data from iCloud")

            dispatch_async(dispatch_get_main_queue(), {  
                self.tableView.reloadData()

            })

        }

    }

    /

    publicDatabase.addOperation(queryOperation)

}

谢谢，Alessio
