iOS 停止向用户询问照片库权限

Question

iOS 不再要求用户提供照片库权限。即使我从设备上删除该应用程序。这也发生在模拟器上。

switch ([ALAssetsLibrary authorizationStatus])
{
    case ALAuthorizationStatusAuthorized:
        RPMLog(@"authorized");
        break;
    case ALAuthorizationStatusDenied:
        RPMLog(@"denied");
        break;
    case ALAuthorizationStatusNotDetermined:
        RPMLog(@"not determined");
        break;
    case ALAuthorizationStatusRestricted:
        RPMLog(@"restricted");
        break;
}

我在第一次安装应用程序时已经获得授权。在此之前，没有其他事件或屏幕要求提供照片来触发用户提示。

然后我在 SavedPhotos 中请求 numberOfAssets 并在没有访问提示的情况下获取它:

ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:^(ALAssetsGroup *group, BOOL *stop) {

    if (!group) return;

    UIActionSheet *actionSheet = nil;
    if (([group numberOfAssets] > 0))
    {
        actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", nil) destructiveButtonTitle:nil otherButtonTitles:NSLocalizedString(@"Take new photo", nil), NSLocalizedString(@"Use last photo taken", nil), NSLocalizedString(@"Choose existing", nil), nil];
    }
    else
    {
        actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", nil) destructiveButtonTitle:nil otherButtonTitles:NSLocalizedString(@"Take new photo", nil), NSLocalizedString(@"Choose existing", nil), nil];
    }

    actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
    [actionSheet showFromTabBar:self.tabBar];
    [TestFlight passCheckpoint:@"New Look: Tab Bar"];

} failureBlock:^(NSError *error) {

    NSAssert(!error, [error description]);
}];

Answer 1

由于问题是照片库权限，还有其他方法可以不更改系统时钟并关闭设备。

您可以转到“设置”应用

(General > Reset > Reset Location & Privacy).

这将使应用程序再次请求照片库、位置和其他权限。
