Is user_photos needed? - ios

Question

Please excuse the elementary question but I am pretty confused on requesting Facebook permissions for my app. My app allows users to select photos then login to their facebook page and those photos are posted on their timeline. I am requesting manage_pages, publish_pages, and publish_actions. In my developer account I added two testers who are friends of mine and we thoroughly tested the process. Everything works perfectly. But when I created a Test User (the one where facebook creates a generic account) my app doesn't post photos to their wall. I granted the test user the same permissions. I am now wondering if I need to call user_photos as another requested permission. I don't think I do since I am not requesting access to the users photos or albums. I am simply posting photos to their timeline which I thought is what publish_pages and publish_actions does. Can you look at the code and see if you can find what I am doing wrong?

{
if ([self.selectedImages count] > 0)
{
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior = FBSDKLoginBehaviorWeb;
[login logInWithPublishPermissions:#[#"publish_actions"]
fromViewController:self
handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
NSLog(#"Process error");
} else if (result.isCancelled) {
NSLog(#"Cancelled");
} else {
NSLog(#"Logged in");
[self shareSegmentWithFacebookComposer];
}
}];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"No Photos" message:#"You have not selected any photo." delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}
}
-(void)shareSegmentWithFacebookComposer{
if ([[FBSDKAccessToken currentAccessToken] hasGranted:#"publish_actions"]) {
[self publishFBPost]; //publish
} else {
NSLog(#"no publish permissions");
}
}
-(void) publishFBPost{
NSMutableArray* photos = [[NSMutableArray alloc] init];
for (NSString* imageFile in self.selectedImages) {
UIImage *image = [UIImage imageWithContentsOfFile:[dataPath stringByAppendingPathComponent:imageFile]];
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = image;
photo.userGenerated = YES;
[photos addObject:photo];
}
FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
content.photos = [photos copy];
[FBSDKShareDialog showFromViewController:self
withContent:content
delegate:nil];
[FBSDKShareAPI shareWithContent:content delegate:nil];
viewThanks.hidden = NO;
[NSTimer scheduledTimerWithTimeInterval:4.5 target:self selector:#selector(start) userInfo:nil repeats:NO];
FBSDKShareDialog *shareDialog = [FBSDKShareDialog new];
[shareDialog setMode:FBSDKShareDialogModeAutomatic];
[shareDialog setShareContent:content];
[shareDialog show];
}

There were publish_stream permission to upload photos but in the latest SDK publish_actions have replaced publish_actions so you only need publish_actions. And if you want to see the user's photos then you need the user_photos permission.
