tl;dr: A MobileSubstrate tweak for Snapchat to enable saving of images, disable image expiry counters, and disable screenshot notifications.
- Install and configure Theos (http://iphonedevwiki.net/index.php/Theos/Getting_Started)
- Clone repo and run 'make package'
- Copy .deb to iOS device
- Run 'dpkg -i packagename.deb'
- Terminate and restart any running instances of Snapchat
- Configure tweak options in iOS Settings
- Profit!
- This is not an "exploit" for Snapchat - Snapchat is not "broken", it's runtime has been modified. There's a big difference here.
- Works only on jailbroken devices
- Requires PreferenceLoader to installed on the device
- Use at your own risk!
