【问题描述】：

我正在学习教程，但遇到了任何类型错误的障碍。我能够解决其他问题，但这个问题正在踢我的尾巴。

这是视图控制器代码：

import UIKit

class ViewController: UIViewController 

//Our web service url 
let URL_GET_TEAMS:String = "http://192.168.43.207/MyWebService/api/getteams.php"

override func viewDidLoad() 
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.


    //created NSURL
    let requestURL = NSURL(string: URL_GET_TEAMS)


    //creating NSMutableURLRequest
    let request = NSMutableURLRequest(URL: requestURL!)

    //setting the method to post
    request.HTTPMethod = "GET"

    //creating a task to send the post request
    let task = NSURLSession.sharedSession().dataTaskWithRequest(request)
        data, response, error in

        //exiting if there is some error
        if error != nil
            print("error is \(error)")
            return;
        

        //parsing the response
        do 
            //converting resonse to NSDictionary
            var teamJSON: NSDictionary!
            teamJSON =  try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary

            //getting the JSON array teams from the response
            let teams: NSArray = teamJSON["teams"] as! NSArray

            //looping through all the json objects in the array teams
            for i in 0 ..< teams.count

                //getting the data at each index
                let teamId:Int = teams[i]["id"] as! Int!
                let teamName:String = teams[i]["name"] as! String!
                let teamMember:Int = teams[i]["member"] as! Int!

                //displaying the data
                print("id -> ", teamId)
                print("name -> ", teamName)
                print("member -> ", teamMember)
                print("===================")
                print("")

            

         catch 
            print(error)
        
    
    //executing the task
    task.resume()



override func didReceiveMemoryWarning() 
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.

以下行引发错误： //获取每个索引处的数据 让 teamId:Int = teams[i]["id"] as！诠释！ 让 teamName:String = teams[i]["name"] as！细绳！ 让 teamMember:Int = teams[i]["member"] as！诠释！

任何帮助将不胜感激。

【参考方案1】：

替换

的所有实例

teams[i][...]

与：

(teams[i] as! NSDictionary)[...]

谢谢！成功了！
