As the title states, an instance of UIVideoEditorController in an iOS 7 device causes a crash when you set the property videoMaximumDuration. This is the error that is logged in the console:
"Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITextView initWithFrame:textContainer:]: unrecognized selector sent to instance"
Any ideas why this is happening? This works fine in iOS 6.
