Why is Xcode 4.3.1 putting red strikethrough through this protected variable?

Question

Makes total sense that you can't access myPrivateInt. But myProtectedInt is totally accessible here (compiles fine). So why's it got that annoying red strikethrough running through it?

Xcode 4.3.1 using iOS SDK 5.1.

Answer 1

Overriding a protected method in child a class with public access modifier is considered a compromising behavior by XCode. Even though your code is syntactically correct , that strikeout text is a simple warning for you to revise your code to make sure you're not exposing one of your internally important class method to outside world.

Edit: Seems like an Xcode bug.
