cocoa - Need help to solve Window Opening Problem -


I have followed the tutorial for Mac OS X for Mac OS X, but I have been returned with 2 warnings Which closes it working / opening. These are two warriors:

How can I solve this problem?

Warnings mean that the object in question (as far as the compiler knows) Does not imply that this means that your window controller is not hereditary with the right superclass, or the pointer has the wrong type in the window controller. It may or may not be the reason for opening your window, it is impossible to tell by the warnings alone.

EDIT: From your whole code it seems that you are declaring your controller as an inheritance from NSObject, instead of NSWindowController
