flutter ios 照片权限总是返回权限永久被拒绝

问题描述 投票：0回答：4

我正在使用 flutter 创建适用于 iOS 和 Android 的应用程序。我需要 iOS 和 Android 的 

photos
和 
storage
权限才能访问照片以更新用户个人资料图片。 我使用 
permission_handler
包来请求权限。这在 Android 中运行良好，但在 iOS 中则不然。

<key>NSPhotoLibraryUsageDescription</key>
<string>We need Photos access to allow you to update Profile Picture.</string>

var permission = Platform.isAndroid
        ? Permission.storage
        : Permission.photos;

var permissionStatus = await permission.request();

print("isGranted: " +
        permissionStatus.isGranted.toString() +
        " isDenied: " +
        permissionStatus.isDenied.toString() +
        " isLimited: " +
        permissionStatus.isLimited.toString() +
        " isRestricted: " +
        permissionStatus.isRestricted.toString() +
        " isPermanentlyDenied: " +
        permissionStatus.isPermanentlyDenied.toString());

flutter：isGranted：false isDenied：false isLimited：false isRestricted：false isPermanentlyDenied：true

我尝试在模拟器（iPhone 12pro max）上卸载并重新安装该应用程序，但仍然无法请求权限（显示请求弹出窗口）。

我尝试了这个，这个，这个和这个。但问题仍然存在。

首先将以下代码复制并粘贴到您的 podfile 中。然后设置

'PERMISSION_PHOTOS=1'
，如果你不想使用其他权限可以删除或设置它=0（exp 
'PERMISSION_CAMERA=0'
，）。

post_install do |installer|
   installer.pods_project.targets.each do |target|
     flutter_additional_ios_build_settings(target)
     target.build_configurations.each do |config|
           # You can remove unused permissions here
           # e.g. when you don't need camera permission, just add 'PERMISSION_CAMERA=0'
           config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
                '$(inherited)',
                ## dart: PermissionGroup.calendar
    
                ## dart: PermissionGroup.reminders
    
                ## dart: PermissionGroup.contacts
    
                ## dart: PermissionGroup.camera
                'PERMISSION_CAMERA=1',
                ## dart: PermissionGroup.microphone
                'PERMISSION_MICROPHONE=1',
                ## dart: PermissionGroup.speech
                'PERMISSION_SPEECH_RECOGNIZER=1',
                ## dart: PermissionGroup.photos
                'PERMISSION_PHOTOS=1',
                ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
    
                ## dart: PermissionGroup.notification
    
                ## dart: PermissionGroup.mediaLibrary
                'PERMISSION_MEDIA_LIBRARY=1',
                ## dart: PermissionGroup.sensors
    
                ## dart: PermissionGroup.bluetooth
    
                ## dart: PermissionGroup.appTrackingTransparency
                'PERMISSION_APP_TRACKING_TRANSPARENCY=1',
                ## dart: PermissionGroup.criticalAlerts
                'PERMISSION_SENSORS=1'
          ]
       end
   end
end

然后将其添加到 info.plist 文件中

<key>NSPhotoLibraryUsageDescription</key>
<string>We need Photos access to allow you to update Profile Picture.</string>

最后，在您的项目中使用 permission_handler 插件，并在您想要请求权限的位置添加此代码。

var permissionStatus = await permission.request();

使用最新的

permission_handler:
包。 将照片权限添加到您的 
Info.plist
文件。

 <!-- Permission options for the `photos` group -->
    <key>NSPhotoLibraryUsageDescription</key>
    <string>photos</string>

将以下内容添加到您的 Podfile 文件中：

post_install do |installer|
  installer.pods_project.targets.each do |target|
    ... # Here are some configurations automatically generated by flutter

    # Start of the permission_handler configuration
    target.build_configurations.each do |config|

      # You can enable the permissions needed here. For example to enable camera
      # permission, just remove the `#` character in front so it looks like this:
      #
      # ## dart: PermissionGroup.camera
      # 'PERMISSION_CAMERA=1'
      #
      #  Preprocessor definitions can be found in: https://github.com/Baseflow/flutter-permission-handler/blob/master/permission_handler_apple/ios/Classes/PermissionHandlerEnums.h
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',

        ## dart: PermissionGroup.calendar
        # 'PERMISSION_EVENTS=1',

        ## dart: PermissionGroup.reminders
        # 'PERMISSION_REMINDERS=1',

        ## dart: PermissionGroup.contacts
        # 'PERMISSION_CONTACTS=1',

        ## dart: PermissionGroup.camera
        # 'PERMISSION_CAMERA=1',

        ## dart: PermissionGroup.microphone
        # 'PERMISSION_MICROPHONE=1',

        ## dart: PermissionGroup.speech
        # 'PERMISSION_SPEECH_RECOGNIZER=1',

        ## dart: PermissionGroup.photos
         'PERMISSION_PHOTOS=1',

        ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
        # 'PERMISSION_LOCATION=1',

        ## dart: PermissionGroup.notification
        # 'PERMISSION_NOTIFICATIONS=1',

        ## dart: PermissionGroup.mediaLibrary
        # 'PERMISSION_MEDIA_LIBRARY=1',

        ## dart: PermissionGroup.sensors
        # 'PERMISSION_SENSORS=1',   

        ## dart: PermissionGroup.bluetooth
        # 'PERMISSION_BLUETOOTH=1',

        ## dart: PermissionGroup.appTrackingTransparency
        # 'PERMISSION_APP_TRACKING_TRANSPARENCY=1',

        ## dart: PermissionGroup.criticalAlerts
        # 'PERMISSION_CRITICAL_ALERTS=1'
      ]

    end 
    # End of the permission_handler configuration
  end
end

如果您需要添加更多权限。删除您想要使用的权限前面的 # 字符。例如

   ## dart: PermissionGroup.photos
             'PERMISSION_PHOTOS=1',

颤抖中：

var request;
var status = await Permission.photos.request();
if (status.permanentlyDenied) {
    //Open app settings to manually enabling the permisisons
    await openAppSettings();
} else {
   //request for permissions
   result = await Permission.photos.request().isGranted;
}

终于 清洁和重建

iOS 上权限包的行为已更改为默认拒绝所有权限。您必须更新 PList 并打开您希望在应用程序中使用的权限才能使其正常工作。

删除 Info.plist 底部的旧内容：'''post_install do...'''

并将其替换为：

post_install do |installer|
   installer.pods_project.targets.each do |target|
     flutter_additional_ios_build_settings(target)
     target.build_configurations.each do |config|
           # You can remove unused permissions here
           # e.g. when you don't need camera permission, just add 'PERMISSION_CAMERA=0'
           config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
                '$(inherited)',
                ## dart: PermissionGroup.calendar
    
                ## dart: PermissionGroup.reminders
    
                ## dart: PermissionGroup.contacts
    
                ## dart: PermissionGroup.camera
                'PERMISSION_CAMERA=1',
                ## dart: PermissionGroup.microphone
                'PERMISSION_MICROPHONE=1',
                ## dart: PermissionGroup.speech
                'PERMISSION_SPEECH_RECOGNIZER=1',
                ## dart: PermissionGroup.photos
                'PERMISSION_PHOTOS=1',
                ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
    
                ## dart: PermissionGroup.notification
    
                ## dart: PermissionGroup.mediaLibrary
                'PERMISSION_MEDIA_LIBRARY=1',
                ## dart: PermissionGroup.sensors
    
                ## dart: PermissionGroup.bluetooth
    
                ## dart: PermissionGroup.appTrackingTransparency
                'PERMISSION_APP_TRACKING_TRANSPARENCY=1',
                ## dart: PermissionGroup.criticalAlerts
                'PERMISSION_SENSORS=1'
          ]
       end
   end
end
