Hi All,
I have a UIViewController as follows. Its just an "About Box", with a
navigation bar and button (to cancel) and two labels.
The controller was built with Interface Builder. The Navigation Bar
and two labels are IBOutlets. According to IB, they are properly
connected. I did not know what to connect the Navigation Items outlet
to, so they are currently unconnected (formerly, they were connected
to File's Owner which did not help).
+ File's Owner
+ First Responder
+ View
+ Navigation Bar
+ Navigation Item (Title)
+ Bar Button
+ Label 1
+ Label 2
When the app starts, I tap a button and bring up the About box. Then I
dismiss it. That is it.
When the view is dismissed by tapping Cancel, NSZombie reports:
-[UINavigationBar willMoveToSuperview:]: message sent to
deallocated instance
If I add an extra [???] retain to the navigationBar in ViewDidLoad,
NSZombie Reports:
-[CALayer release]: message sent to deallocated instance
(1) How do I get to the CALayer and add an extra retain to stop this crash?
(2) What am I missing WRT retain counts? Why are these retain counts
so messed up?
Jeff
