If I have an protocol (say UIPickerViewDataSource) and I implement its required methods, do I need to declare those methods in the header file of my class? At the moment I'm not doing so and I get a warning of incomplete implementation (although everything works fine). If I do add the required methods in the then I don't get such warnin...

Now I'd like to upgrade to a more recent version and don't know how I should proceed about this. Just install a newer version?

Is this some type of overla...
