No Underscores Edit on GitHub

Don’t underscore-prefix private helper methods or static C functions.

- (void)_buttonAction:(CKComponent *)sender
{
  _logEvent(@"button tapped");
}

Subclassing components is discouraged, so there’s no need to worry about distinguishing public and private methods or colliding with methods in the superclass.

- (void)buttonAction:(CKComponent *)sender
{
  logEvent(@"button tapped");
}
