plist的读取和写入

         // 从plist中读取数组数据
         let arrPath = Bundle.main.path(forResource: "ArrayPList", ofType: "plist")!
         let arr = NSArray(contentsOfFile: arrPath)!

         // 数组 写入 plist文件
         arr.write(toFile: "/Users/yaoshuai/Desktop/ArrP.plist", atomically: true)

         // 从plist中读取字典数据
         let dictPath = Bundle.main.path(forResource: "DictPList.plist", ofType: nil)!
         let dict = NSDictionary(contentsOfFile: dictPath)!

         // 字典 写入 plist文件
         dict.write(toFile: "/Users/yaoshuai/Desktop/DictP.plist", atomically: true)
