AWPercentDrivenInteractiveTransition is a drop-in replacement for
UIPercentDrivenInteractiveTransition for use in custom container view controllers.
Why do you need it? Because Apples own

Alternatively you can directly add the
AWPercentDrivenInteractiveTransition.m source files to your project.
AWPercentDrivenInteractiveTransition.monto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.
If you don't want to compile my code all the time, there's an Xcode project in the

libAWPercentDrivenInteractiveTransition.a library file you can include in your project. Just remember to include the original
LICENCE file in your source code.
Use as you would do with a regular
UIPercentDrivenInteractiveTransition. Either by letting your custom interaction controller subclass
AWPercentDrivenInteractiveTransition or by having an instance and manually call the

This is what the standard
