    var cardObject = PFObject(className: "YourCard")
    cardObject["cardNumber"] = cardNumber
    cardObject["balance"] = balance
    cardObject["expire"] = date
    cardObject["validFlg"] = cardStatus
    cardObject.saveInBackgroundWithBlock {
        (success: Bool!, error: NSError!) -> Void in
        if (success != nil) {
            NSLog("Object created with id: \(cardObject.objectId)")
        } else {
            NSLog("%@", error)
        }
    }
    dbId = cardObject.objectId

我无法获得objectId,我怎么能得到它？非常感谢你提前.
