The status bar is in the menu bar, and the menu bar is in the same nib as your app controller. The status bar probably initializes itself in an -awakeFromNib method. Whether that method runs before or after your -awakeFromNib method is completely unpredictable. > I can see why it's a bad thing in theory, but I haven't had any problems with > this approach. Are you prepared to have your app crash and burn on launch for every user that installs some upcoming OS revision (perhaps even a minor update)? I'm serious; this happens. Doing things that shouldn't work, just because they do work at the moment, is asking for trouble since the underlying behavior of the system frameworks can change in the future. (This is especially painful if you're not on the expen$ive Apple developer plans that get you access to OS betas, because that means you won't get a chance to find any of these crashes before your customers do. Instead you find yourself frantically debugging on the day the new OS comes out, while your mailbox fills up with crash reports and complaints.) > Anyway, back to subject.

Check whether the status bar is nil before you ask for its frame, instead of working around the aftermath of calling a struct accessor on nil. But doing this is still a hack, for the reason I described above. It's pretty clear that you shouldn't be doing anything with NSStatusBar in an -awakeFromNib method in the main nib. —Jens_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
