排序任意对象Swift 3的数组 [英] sort array of anyobject Swift 3

问题描述

我正在尝试排序任何对象的数组，但无法做到这一点。我从AnyObject格式的Parse数据库中获取一些数据。根据下面的数据，我想通过NAME对AnyObject数组进行排序。以下是我的代码 -

  let sortedArray =（myArray as！[AnyObject]）。sorted（by：{（dictOne，dictTwo ） - > Bool in 
 let d1 = dictOne [NAME]！as AnyObject; //此行给出错误下标的模糊使用
 let d2 = dictTwo [NAME]！as AnyObject; //这一行给出错误下标的模糊使用
 
返回d1< d2 
}）
  

myArray看起来像这样 -

  {
 LINK =www .xxx.com; 
 MENU =角色; 
MENU_ID= 1; 
 NAME =A Name; 
 SUBMENU =XXX; 
Training_ID= 2; 
}，
 {
 LINK =www.xyz.com; 
 MENU =角色; 
MENU_ID= 2; 
 NAME =B name; 
 SUBMENU =jhjh; 
Training_ID= 6; 
}，
 {
 LINK =www.hhh.com; 
 MENU =角色; 
MENU_ID= 3; 
 NAME =T name; 
 SUBMENU =kasha; 
Training_ID= 7; 
}，
 {
 LINK =www.kadjk.com; 
 MENU =角色; 
MENU_ID= 5; 
 NAME =V name; 
 SUBMENU =ksdj; 
Training_ID= 1; 
}，
 {
 LINK =www.ggg.com; 
 MENU =角色; 
MENU_ID= 4; 
 NAME =K name; 
 SUBMENU =idiot; 
Training_ID= 8; 
}，
 {
 LINK =www.kkk.com; 
 MENU =角色; 
MENU_ID= 6; 
 NAME =s name; 
 SUBMENU =BOM / ABOM / BSM; 
Training_ID= 12; 
} 
  

任何帮助将不胜感激。谢谢！

解决方案

为什么要将数组转换为 [AnyObject] 而不是将数组转换为 [[String：Any]] 意味着数组 Dictionary> / code>并告诉编译器该数组包含字典作为对象。

 如果让array = myArray为？ [[String：Any]] {
 let sortedArray = array.sorted（by：{$ 0 [NAME] as！String< $ 1 [NAME] as！String}）
} 
  

注意：由于您有 NAME 键与 String 在数组的每个字典的值我有力包装它与下标。

I am trying to sort an array of anyobject, but not able to do it.I get some data from Parse database in AnyObject format. As per below data, I want to sort this AnyObject array by "NAME". Below is my code -

  let sortedArray = (myArray as! [AnyObject]).sorted(by: { (dictOne, dictTwo) -> Bool in
                                                            let d1 = dictOne["NAME"]! as AnyObject; // this line gives error "Ambiguous use of subscript"
                                                            let d2 = dictTwo["NAME"]! as AnyObject; // this line gives error "Ambiguous use of subscript"

                                                            return d1 < d2
                                                        })

myArray looks like this -

 {
            LINK = "www.xxx.com";
            MENU = Role;
            "MENU_ID" = 1;
            NAME = "A Name";
            SUBMENU = "XXX";
            "Training_ID" = 2;
        },
            {
            LINK = "www.xyz.com";
            MENU = Role;
            "MENU_ID" = 2;
            NAME = "B name";
            SUBMENU = "jhjh";
            "Training_ID" = 6;
        },
            {
            LINK = "www.hhh.com";
            MENU = Role;
            "MENU_ID" = 3;
            NAME = "T name";
            SUBMENU = "kasha";
            "Training_ID" = 7;
        },
            {
            LINK = "www.kadjk.com";
            MENU = Role;
            "MENU_ID" = 5;
            NAME = "V name";
            SUBMENU = "ksdj";
            "Training_ID" = 1;
        },
            {
            LINK = "www.ggg.com";
            MENU = Role;
            "MENU_ID" = 4;
            NAME = "K name";
            SUBMENU = "idiot";
            "Training_ID" = 8;
        },
            {
            LINK = "www.kkk.com";
            MENU = Role;
            "MENU_ID" = 6;
            NAME = "s name";
            SUBMENU = "BOM/ABOM/BSM";
            "Training_ID" = 12;
        }

Any help would be much appreciated. Thanks!

解决方案

Why are converting array to [AnyObject] instead of that convert the array to the [[String:Any]] means Array of Dictionary and tell the compiler that array contains Dictionary as objects.

if let array = myArray as? [[String:Any]] {
   let sortedArray = array.sorted(by: { $0["NAME"] as! String < $1["NAME"] as! String })
}

Note: As of you are having NAME key with String value in your each dictionaries of array I have force wrapped it with the subscript.
