I have a video recording app and I was wondering if it is possible to create a button that says "View Camera Roll" and when you click on that button it would launch the Photos app on your phone.
I see a common use for something like this is UIImagePickerController in my actual app which is close to what I want, but I don't want the user to be picking one for something other than just viewing it and browsing through their photos. It would be much easier to just have a link to the actual Photos app.
You cannot open the default Photo app. In iOS, an application needs to register for a URL schemes to be opened from elsewhere, and default photo app does not have one.
