ios - 如何在 Parse API 中访问字典数组

Question

我将一组字典保存到 Parse，它正确显示在 User 类中。我可以在断点处 po user 并且该数组正确显示为 User 的属性之一。但是，我根本无法访问此数据，我收到运行时错误 EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)。我正在尝试使用 user.userFbFriendsDetail 访问数据以保存到局部变量。这是我 po User 时的控制台结果，我不知道如何使用 userFBFriendsDetail 数组。非常感谢您的帮助!

<PFUser: 0x7fe1dd281010, objectId: onHQnYR5d2, localId: (null)> {
    facebookID = xxxxxxx
    fbEmail = xxxxxx
    fbGender = male;
    fbName = "John Doe";
    friendsUsingTheApp =     (
        "<PFUser: 0x7fe1dbd30210, objectId: oqKnKZMN3d, localId: (null)>",
        "<PFUser: 0x7fe1dbd30510, objectId: hUNZvZC4fD, localId: (null)>"
    );
    userFbFriendsDetail =     (
                {
            email = "fake@fake.com";
            facebookID = 1111111111;
            profileImage = "<PFFile: 0x7fe1dfe28422>";
        },
                {
            email = "fake@fake.com";
            facebookID = 222222222222;
            profileImage = "<PFFile: 0x7fe1dbd1ffd1>";
        }
    );
}

编辑:这是 PFUser 类的定义:

class User : PFUser {
   override class func initialize() {
      struct Static {
         static var onceToken : dispatch_once_t = 0;
      }
      dispatch_once(&Static.onceToken) {

         self.registerSubclass()
      }
   }

   @NSManaged var gender: String?
   @NSManaged var fbName: String?
   @NSManaged var age: NSNumber?
   @NSManaged var facebookID: String?
   @NSManaged var fbLocale: String?
   @NSManaged var fbTimezone: NSNumber?
   @NSManaged var fbGender: String?
   @NSManaged var fbEmail: String?
   @NSManaged var fbAge: NSNumber?
   @NSManaged var profileImage: PFFile?
   @NSManaged var twitterHandle: String?
   @NSManaged var state: String?
   @NSManaged var birthday: String?
   @NSManaged var friendsUsingTheApp:Array<String>
   @NSManaged var userFbFriendsDetailDict:Dictionary<String, AnyObject>
}

Answer 1

userFbFriendsDetailDict应该是 Array<Dictionary<String, AnyObject>> 类型. (您应该以该名称访问它，而不是 userFbFriendsDetail )。
