Unity 安卓/ios權(quán)限插件

前面兩篇分別解決了Unity中安卓和ios權(quán)限的獲取、被拒情況下的處理方法，這篇我們把他們整合成一整個插件。
首先是調(diào)用方法，安卓和ios不一樣，安卓可以拒絕后再由系統(tǒng)發(fā)起申請，ios則不行，因此安卓有三種狀態(tài)，ios只有兩種：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class PermissionsStateExample : MonoBehaviour
{
    public Button m_AskMicrophonePermissionStateButton;

                break;
            default: break;

    }

    {

如果不看上面兩篇這里可能會比較吃力，但是懶人就方便了。
用的時候注意一下使用注意點，我也寫在README里了：

ios使用注意：
--使用麥克風(fēng)權(quán)限
在info中添加Privacy - Microphone Usage Description描述
--使用相機(jī)權(quán)限
在info中添加Privacy - Camera Usage Description描述
--使用讀取相冊權(quán)限
在info中添加Privacy - Photo Library Additions Usage Description描述和Privacy - Photo Library Usage Description描述
還需要在TARGETS-UnityFramework-General-Frameworks and Libraries中添加Photos.framework

安卓使用注意：
需修改Unity 默認(rèn)AndroidManifest文件，文件路徑為
Mac系統(tǒng)：Unity.app安裝同級目錄： PlaybackEngines/AndroidPlayer/Apk/
Win系統(tǒng)：Unity安裝目錄下面（如果hub安裝的就有hub，非hub安裝的就少hub這一層，可以桌面右鍵圖標(biāo)打開文件所在位置）C:\Program Files\Unity\Hub\Editor\2019.4.5f1\Editor\Data\PlaybackEngines\AndroidPlayer\Apk
在文件中添加需要的權(quán)限：
--使用麥克風(fēng)權(quán)限
<uses-permission android:name="android.permission.RECORD_AUDIO" />
--使用相機(jī)權(quán)限
<uses-permission android:name="android.permission.CAMERA" />
--使用讀取相冊權(quán)限
在unity導(dǎo)出設(shè)置othersetting中的write permission(寫入權(quán)限)設(shè)置為External（SDCard）

有小伙伴說ios打包的時候碰到如下問題：

Undefined symbols for architecture arm64: "_OBJC_CLASS_$_CTCellularData", referenced from: objc-class-ref in Permission.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

調(diào)研后發(fā)現(xiàn)是CoreTelephony.framework庫丟失，添加后即可。
