CKContainer accountStatusWithCompletionHandler returns wrong value

问题

accountStatusWithCompletionHandler method returns .NoAccount value. Any idea why returned value is not .Available? I am logged in to iCloud, and connecting to internet.

Doc says .NoAccount means:

The user’s iCloud account is not available because no account information has been provided for this device.

I do not receive any error. The reason may be that app is not using private database? Doc says:

Call this method before accessing the private database to determine whether that database is available.

回答1:

Figured out, iCloud Drive was turned off for the app.

回答2:

This code sample show status with iCloud. Probably request permission or promo user to login on .NoAccount case. I am thinking this is a case when you are not connected to the iCloude.

let container = CKContainer.defaultContainer()
    container.accountStatusWithCompletionHandler({status, error in
        switch status {
            case .Available, .Restricted:
            container.requestApplicationPermission(CKApplicationPermissions.PermissionUserDiscoverability,
                completionHandler: { applicationPermissionStatus, error in
                // handle applicationPermissionStatus for statuses like CKApplicationPermissionStatus.Granted, .Denied, .CouldNotComplete, .InitialState
            })
            case .CouldNotDetermine, .NoAccount:
                // Ask user to login to iCloud
        }
    })
