iOS获取设备和APP权限信息（内含plist文件的读写）

前言

下面各种获取到的信息分为了两大类，一种是获取APP载体设备当前的各种信息，另一种是APP自身能取得的权限，两部分中的“说在前面的”只是记录了一个我的学习过程，所有调取代码都在示例代码或者demo里，可跳过这部分自取代码
这是我的demo地址 GitHub，我将其封装成了一个工具类，欢迎clone使用，其中蓝牙功能没有封装进去，下面我再说具体原因

获取设备当前的各种信息

说在前面的：
1. 目录前面11条的信息很好获取，好多都是一行代码的事，参考博客:
  1. iOS 如何获取设备的各种信息
  2. iOS怎么判断设备的WiFi开关是否打开？
  3. 设备像素比是什么：Android dp 和 CSS px
2. 到判断蓝牙和定位开关状态就要导入苹果官方提供的框架了，至于如何导入框架：在工程文件General -> Linked Frameworks and Libraries中点加号添加即可
  1. 定位参考博客：iOS 判断APP是否打开定位，并实现直接跳转打开定位
  2. 蓝牙参考博客：iOS中蓝牙开发核心就是协议方法-(void)centralManagerDidUpdateState:(CBCentralManager *)central的回调和参数 central.state 的几种枚举值状态，判断一下就好，因为要遵循主设备的委托——CBCentralManagerDelegate，所以没有将其封装在工具类中。

获取APP能获取到的权限信息(内含plist文件的读写)

说在前面的
1. 以下获取权限信息分为两类，一种是工程.plist配置文件中的权限，例如目录的1～4；还有一种是用户应用层的权限，比如目录5，6的通知权限
2. 要获取工程.plist配置文件中的权限，我们就要学习一下plist文件的读写：
  - plist文件，如字面意思即plist后缀类型的文件，这个文件是以 key value 存放的键值对的值。它全名是：Property List，属性列表文件，它是一种用来存储串行化后的对象的文件。属性列表文件的扩展名为.plist ，因此通常被称为 plist文件。plist文件是标准的xml格式的。我们在日常开发中可以用它来存储一些系统的的用户信息，系统的配置信息等。
  - 然后我们理解一下NSBundle（束）的概念，这里可以参考一下博客 iOS：NSBundle的一些理解 ,对这个概念我现在理解的也比较肤浅，仅限于使用阶段，有空会再次学习。
  - 然后就是plist文件的读写，参考博客： plist 文件读写。先获取主束（包含了程序会使用到的资源），然后读取plist文件的路径，将数据读取存放到一个字典中，判断权限时搜索字典有没有所需权限的key值即可判断权限有无。这里给出一些常用权限设置方法 iOS10适配——相机，通讯录，麦克风等权限设置 , iOS – iOS8常用权限请求及设置逻辑总汇
  - 注意因为plist文件是xml格式的，所以这些key值具体内容不是 proper list 格式打开显示的那些权限关键字，要以源码格式打开plist文件才能看到其真正的权限key值
3. 推送权限判断参考博客（等系统学习后再另开一篇博客介绍）：

2019.11.04 更新

在苹果更新 iOS 13以后，原来的蓝牙权限在IOS 13被遗弃，改成了 NSBluetoothAlwaysUsageDescription

在info.plist里面添加

NSBluetoothAlwaysUsageDescription 或者 Privacy – Bluetooth Peripheral Usage Description 权限字段 value 也是你的蓝牙用途
