Xcode's "Incomplete implementation" warning

Question

Sometimes I forget to implement a method in one of my classes, and Xcode displays a "Incomplete implementation" warning.

Is there any way in Xcode to see which method implementation is missing?

Answer 1

In your error view (command+4, by default, or the 4th tab in the left hand view) you can click the little arrow next to the warning, and it should tell you

Method definition for 'blah' not found

Answer 2

I've found that sometimes the Log Navigator is the only way to show the actual problem - in at least one case, the error view didn't help me. To see the Log Navigator, you can use View > Navigators > Show Log Navigator (or ⌘7 by default).
