UIDocumentInteractionController works but doesn't show "Save Image"

Question

I create and present a UIDocumentInteractionController with a valid url to a saved image but when I present the controller "Save Image" does not appear.

NSURL *url = ...;
self.interactionController = [UIDocumentInteractionController interactionControllerWithURL:url];
[self.interactionController presentOptionsMenuFromBarButtonItem:sender animated:YES];

I have verified self.interactionController.UTI is a valid image type (jpeg)

______Actual_______ vs.____Expected_____

Note* If anyone knows a better way to format those images please be my guest

Answer 1

In order to have the option to save to the camera roll, the app must have permission to access photos.

Relative to ALAuthorizationStatus ([ALAssetsLibrary authorizationStatus])

"Save Image" is displayed for

1. ALAuthorizationStatusAuthorized
2. ALAuthorizationStatusNotDetermined

"Save Image" is not displayed for

1. ALAuthorizationStatusRestricted
2. ALAuthorizationStatusDenied

You can do a check like this:

#import <AssetsLibrary/AssetsLibrary.h>

- (BOOL)canSaveToCameraRoll
{
    ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus];
    return (status == ALAuthorizationStatusAuthorized || status == ALAuthorizationStatusNotDetermined);
}
