从对象Swift获取价值

Question

如何从PFObject数组中获取RestaurantName的值？

我试图将objectId中的RestaurantName作为字符串。

当前尝试

var stringObjectIds: [String] = self.restaurantObjects.map { $0.objectForKey("RestaurantName", "objectId") as String }

PFObject数组

[<FoodPhotoTest2: 0x7fa37e7ddb50, objectId: Jkl28Tcjjv, localId: (null)> {
    PhotoName = "Korean Dish";
    PhotoUploaded = "<PFFile: 0x7fa37e7f31d0>";
    RestaurantName = "<restauranttest2: 0x7fa37e784670, objectId: JNT2dLEL79>";
    UserUploaded = "<PFUser: 0x7fa37e4be170, objectId: wNJPsJDV6t>";
    Votes = 0;
}]

如果restaurantObjects包含PFObject s，请在地图功能中使用$0.objectId。
