How to determine if photo 'used' was new photo or existing from photo library?

Good question. I'll check the metadata of the taken image from the library.

Awesome! Really enjoy your cool camera library, extremely nice. Thanks!

Thank you for your suggestions!

@danielebogo - Just wanted to check in and see if there was any progress on this request? I am nearing completion of an app using this library, but want to allow the user to save the NEW images to their camera roll when they take a new picture. Have you found a way to determine if a new image is taken, or an existing image was selected?

Thanks!

Hi @jhickman7 ,
unfortunately i haven't find a solution for this issue. It seems it's impossibile to check if the image is already saved directly form the Library. I've found these two posts: URL1 & URL2.
Maybe one solution could be to compare the asset URL. But i'm not sure.

Maybe I don't understand your question, but can't you do the following?

// Save to Camera Roll if from Camera
NSString *source = [metadata objectForKey:@"DBCameraSource"];
NSLog@("source: %@", source);
if( [source hasSuffix:@"Camera"] ){
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
}

If the DBCameraSource is the Camera, then you know the picture was taken with DBCamera and therefore you should save it.

If it is not Camera, then it came from the Camera Roll and do not save it.
