[image_picker] [PHPhotoLibrary authorizationStatus] status is not correct in iOS14+

[zhouxing5311]

it is not correct using [PHPhotoLibrary authorizationStatus] to get the authorization status in iOS14+. such as when you limit your app can access only some photos, then [PHPhotoLibrary authorizationStatus] will return PHAuthorizationStatusAuthorized which is not correct.
to solve the problem, you should use [PHPhotoLibrary authorizationStatusForAccessLevel:PHAccessLevelReadWrite] in iOS14+ to get the correct result.

Hi @zhouxing5311
I'm not sure I can get the context of the issue. Please elaborate the issue in more detail by indicating whether it is related to the Flutter framework or a specific plugin you are using.

[zhouxing5311]

sorry for that, it is in image_picker_ios plugin, class name is FLTImagePickerPlugin.m, method name is checkPhotoAuthorizationForAccessLevel.

I try modifying authorizationStatus to authorizationStatusForAccessLevel:PHAccessLevelReadWrite but the result is still the same. I'm testing on iPhone 14 Pro Max, iOS 16.0.

Demo

Modified snippet code

- (void)checkPhotoAuthorizationForAccessLevel API_AVAILABLE(ios(14)) {
  PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatusForAccessLevel:PHAccessLevelReadWrite];

Which iOS version did you try?

maybe i did't make my point, image selecting behavior has no problem, the question is PHPhotoLibrary authorizationStatus return the result 'PHAuthorizationStatusAuthorized', but the result should be 'PHAuthorizationStatusLimited' , here is my code result.

the reason I bring this up is that i want to show diffrent image select page when your permission is limitted by modifying the source code, so i need to get the correct authorizationStatus. maybe you will add the feature like this to source code?

or when i finish this, i can submit a pull request. i think this is a better experience for user who selected the limited photos. the present behavior may confusing the user that the original image selecting is invalid.

Please check this issue if it's similar to your case: #110176

Also, I re-test this thing again, looks like it has been implemented similar to what you're describing (although the Select more photos dialog shows only once and the design is different), please see in demo:

hi, i don't think this is a similar case, the handling for limit photos is not suitable i think. after selecting the special photos, next time the image picker should show the photos only which is selected by user at the begin time. or the previous selecting is useless, users can not understand what's meaning of the begining select.

@zhouxing5311 Labeling the issue as a proposal for further insight from the team.
