Question

我正在尝试保存创建的事件的对象ID。我已经尝试了异步和同步保存并将对象ID保存在变量中。但我无法从其他类访问对象id的值，但我能够从事件类中访问其他变量

class Event: NSObject, MKAnnotation {

var userImage:UIImage!
var userName:String!
var creatoruserName:String!
var segueIdenifier:String!
var eventId:String!
....
 func addToDB() {
    let event = PFObject(className:"Event")
    let currentUser = PFUser.currentUser()
    event["createdBy"] = currentUser
    event["eventType"] = self.eventType
    event["eventAttributes"] = attributes
    event["eventDate"] = time
    event["locationDescription"] = locationAsString

    if (locationAsPoint != nil){
        event["Location"] = locationAsPoint


         try! event.save()
         self.eventId = event.objectId!

        print("objectId1 \(eventId!)")
        print("objectId2 \(self.eventId!)")

         try! event.save()
    //            event.saveInBackgroundWithBlock {
//                (success: Bool, error: NSError?) -> Void in
//                if (success) {
//                    print("event created")
//                    // The object has been saved.
//                    print("event.objectId! \(event.objectId!)")
//                    self.eventId = event.objectId!
//                    temp_objectId = event.objectId!
//                    print("self.objectId! \(self.eventId!)")
////                    event.seteventID((event.objectId)!)
//                    
//                } else {
//                    // There was a problem, check error.description
//                }
//            }
        }

 //       print("objectId1 \(self.objectId!)")

}

调用此函数时，将打印objectId1的值。当我从segue传递这个时，它不会打印objectid的值。我错过了什么？

if (segue.identifier == "findOutMore") {
    let svc = segue.destinationViewController as! CustomProfileViewController;
    svc.event = self.eventSelected
    print ("event id1 is  \(eventSelected.geteventID())")

它打印nil coz我已经创建了geteventID，如果值为nil，则将其放入其中。

解析ObjectID没有存储在Event类swift
