Unity 安卓/ios权限插件

前面两篇分别解决了Unity中安卓和ios权限的获取、被拒情况下的处理方法，这篇我们把他们整合成一整个插件。
首先是调用方法，安卓和ios不一样，安卓可以拒绝后再由系统发起申请，ios则不行，因此安卓有三种状态，ios只有两种：

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

public class PermissionsStateExample : MonoBehaviour
{
    public Button m_AskMicrophonePermissionStateButton;
    public Button m_AskCameraPermissionStateButton;
    public Button m_AskReadPhotoPermissionStateButton;
    public Button m_AskWritePhotoePermissionStateButton;
    public Button m_OpenAppSettingsButton;
    void Start()
    {
        m_AskMicrophonePermissionStateButton.onClick.AddListener(GetMicrophonePermissionState);
        m_AskCameraPermissionStateButton.onClick.AddListener(GetCameraPermissionState);
        m_AskReadPhotoPermissionStateButton.onClick.AddListener(GetReadPhotoPermissionState);
        m_AskWritePhotoePermissionStateButton.onClick.AddListener(GetWritePhotoPermissionState);
        m_OpenAppSettingsButton.onClick.AddListener(OpenAppSettings);
    }

    void Update()
    {

    }

    void GetMicrophonePermissionState()
    {
        PermissionState permissionState = PermissionsState.GetMicrophonePermissionState();

        switch (permissionState)
        {
            case PermissionState.Allow:
                Debug.Log("Microphone 权限允许");
                break;
            case PermissionState.NotAllow:
                Debug.Log("Microphone 权限不允许");
                break;
            case PermissionState.WaitAsk:
                Debug.Log("Microphone 等待询问");
                break;
            default: break;
        }
    }

    void GetCameraPermissionState()
    {
        PermissionState permissionState = PermissionsState.GetCameraPermissionState();

        switch (permissionState)
        {
            case PermissionState.Allow:
                Debug.Log("Camera 权限允许");
                break;
            case PermissionState.NotAllow:
                Debug.Log("Camera 权限不允许");
                break;
            case PermissionState.WaitAsk:
                Debug.Log("Camera 等待询问");
                break;
            default: break;
        }
    }

    void GetWritePhotoPermissionState()
    {
        PermissionState permissionState = PermissionsState.GetWritePhotoPermissionState();

        switch (permissionState)
        {
            case PermissionState.Allow:
                Debug.Log("WritePhoto 权限允许");
                break;
            case PermissionState.NotAllow:
                Debug.Log("WritePhoto 权限不允许");
                break;
            case PermissionState.WaitAsk:
                Debug.Log("WritePhoto 等待询问");
                break;
            default: break;
        }
    }

    void GetReadPhotoPermissionState()
    {
        PermissionState permissionState = PermissionsState.GetReadPhotoPermissionState();

        switch (permissionState)
        {
            case PermissionState.Allow:
                Debug.Log("ReadPhoto 权限允许");
                break;
            case PermissionState.NotAllow:
                Debug.Log("ReadPhoto 权限不允许");
                break;
            case PermissionState.WaitAsk:
                Debug.Log("ReadPhoto 等待询问");
                break;
            default: break;
        }
    }

    void OpenAppSettings()
    {
        PermissionsState.OpenAppSettings();
    }
}

    NotAllow,
    //允许
    Allow,
    //等待询问
    WaitAsk,
    //不需要的平台
    UnnecessaryPlatform
}

如果不看上面两篇这里可能会比较吃力，但是懒人就方便了。
用的时候注意一下使用注意点，我也写在README里了：

ios使用注意：
--使用麦克风权限
在info中添加Privacy - Microphone Usage Description描述
--使用相机权限
在info中添加Privacy - Camera Usage Description描述
--使用读取相册权限
在info中添加Privacy - Photo Library Additions Usage Description描述和Privacy - Photo Library Usage Description描述
还需要在TARGETS-UnityFramework-General-Frameworks and Libraries中添加Photos.framework

安卓使用注意：
需修改Unity 默认AndroidManifest文件，文件路径为
Mac系统：Unity.app安装同级目录： PlaybackEngines/AndroidPlayer/Apk/
Win系统：Unity安装目录下面（如果hub安装的就有hub，非hub安装的就少hub这一层，可以桌面右键图标打开文件所在位置）C:\Program Files\Unity\Hub\Editor\2019.4.5f1\Editor\Data\PlaybackEngines\AndroidPlayer\Apk
在文件中添加需要的权限：
--使用麦克风权限
<uses-permission android:name="android.permission.RECORD_AUDIO" />
--使用相机权限
<uses-permission android:name="android.permission.CAMERA" />
--使用读取相册权限
在unity导出设置othersetting中的write permission(写入权限)设置为External（SDCard）

2021.4.28更新
有小伙伴说ios打包的时候碰到如下问题：

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)

调研后发现是CoreTelephony.framework库丢失，添加后即可。
