Not finding what you are looking for? Try searching through GitHub for iOS Tweaks with a simple trick, "extension:xm".

Example:

Using the above code will search GitHub for all files with the extension .xm (because Theos by default creates a Tweak.xm file when creating a new tweak). The example above will result in finding tweaks that reference SBAwayController. Not all developers use the .xm file extension, but a large number do, and this will help you in finding those examples.
