swift中JSon数据的处理

import UIKit

class MainTabBarViewController: UITabBarController {
    
    override func  viewDidLoad() {
        super.viewDidLoad()
        //1.获取json文件的地址
        guard let jsonPath = NSBundle.mainBundle().pathForResource("MainVCSettings.json", ofType: nil) else {
            return
        }
        //2.获取json文件的数据
        guard let jsonData = NSData(contentsOfFile: jsonPath) else {
            return
        }
        //3.将json文件的数据转化为swift可读数据
        guard let anyObject = try? NSJSONSerialization.JSONObjectWithData(jsonData, options: .MutableContainers) else {
            return
        }
        
        guard let dicArray = anyObject as? [[String:AnyObject]] else {
            return
        }
        //4.提取json文件数据
        for dic in dicArray {
            //4.1提取数据
            guard let vcName = dic["vcName"] as? String else {
                continue
            }
            guard let title = dic["title"] as? String else {
                continue
            }
            guard let imageName = dic["imageName"] as? String else {
                continue
            }
            //4.2添加控制器
            addChildViewController(vcName, title: title, imageName: imageName)
        }
