提取JSON數據 -

Question

我有從FBSDKGraphRequest中拉出的以下JSON數據結構。我想提取數據並將其放入數組。我對第一個「數據」鍵有困難。

繼承人我FBSDKGR：

let params = ["fields": "name, picture.type(large)"] 
    let request = FBSDKGraphRequest(graphPath: "me/taggable_friends", parameters: params) 
    request!.start { (connection, result, error) -> Void in 

     if error != nil { 
      print("There is some error getting friends", error!) 
     } 
     else if result != nil { 
      print("Here is the result", result!) 

Answer 1

With an extra dependency, if you don't mind.

import SwiftyJSON 

let json = JSON(result) // after you get result from FBSDKGR 
let data = json["data"].array 
for (index, _) in data.enumerated() { 
    if let id = json["data", index, "id"].int { 
      // add to your array 
      if let name = json["data", index, "name"].string { 
       // continue nesting... 
     } 
    } 
}

正如你JSOND DTA是字典的數組所以，我們可以通過下面的方式把結果。首先，我們將採取兩個陣列，一個是名單，另一個是圖片細節。這裏的圖片細節數組是字典數組。讓我們去代碼

var namesArray = [String]() 
var ImageDetailsArrayDict= [[String :AnyObject]]() 

let params = ["fields": "name, picture.type(large)"] 
    let request = FBSDKGraphRequest(graphPath: "me/taggable_friends", parameters: params) 
    request!.start { (connection, result, error) -> Void in 

     if error != nil { 
      print("There is some error getting friends", error!) 
     } 
     else if result != nil { 
      print("Here is the result", result!) 
     if let response = result["data"] as? [[String :AnyObject]] { 

       for i in 0..<response.count { 
        namesArray.append(response[i]["name"] as! String)     
        ImageDetailsArrayDict.append(response[i]["picture"]) 

       } 
       } 
      } 
     } 

現在，我們有兩個數組。所以我們可以很容易地將它填充到tableView中。 祝你好運。
