swift4--代码创建并读取和解析Plist属性列表文件

//plist文件，即属性列表文件，是一种用来存储串行化后的对象的文件。
import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
//        用代码创建plist属性列表文件
//        初始化一个可变字典对象，作为属性列表内容的容器
        let dict:NSMutableDictionary = NSMutableDictionary()
//        设置内容，以键值对的形式添加、
        dict.setObject("Peler", forKey: "Name" as NSCopying)
        dict.setObject("35", forKey: "Age" as NSCopying)
        
//        生成文件的存储路径
        let plistPath = Bundle.main.path(forResource: "demoPlist", ofType: "plist")
//        将可变字典对象写入到指定位置的属性列表文件
        dict.write(toFile: plistPath!, atomically: true)
        
//        读取和解析Plist属性列表文件
//        读取属性列表文件，并转化为可变字典对象
        let data:NSMutableDictionary = NSMutableDictionary.init(contentsOfFile: plistPath!)!
//        将字典对象转化为字符串对象
        let message = data.description
        let name = data["Name"]
        let age = data["Age"]
        
        print(message)
        print(name)
        print(age)
    }

        super.didReceiveMemoryWarning()
