In order for TouchTheVideo to show videos in Camera Roll or Event of the standard Photos application, setting an access permission to the Photos is necessary.
In iOS5.1 or before, access permission to the Photos of the iPhone/iPad was allowed by getting access permission to location services.
From iOS6.0, the access permission specification has been separated into “Location Services”, “Contacts”, “Photos” and so on, and access permission to the Camera Roll is under “Photos” privacy setting.
To watch videos in camera roll, please go to “Settings” app ==> “Privacy” ==> “Photos” and turn on the setting for “T.T.Video” to allow access to your photos.
