WooHoo! My first post to cocoa-dev... and it's to ask -- is this
appropriate for cocoa-dev? I am also working on iPhone apps but have
been just lurking on this list to see if there was any CocoaTouch
discussion. Perhaps someone should create email@hidden
? I digress. I'm new to the Apple Developer community.
For fun, I just created the sample app from SDK5 which is a TabBar
skeleton. I added a Navigation controller to the TabBarController in
the NIB file (thus created a third tab). I added an IBAction called
resetPushed: to the TabBarDelegate. I added a UIBarButtonItem to the
NavigationBar and pointed it to resetPushed:. All seemed to work fine
(all resetPushed: does is tell the TabBarController to
setSelectedIndex:0, nothing fancy). I'm not sure what you are
specifically doing so I can't be sure I replicated your scenario.
All that said, remember this is still BETA. One issue I see right now
is that Interface Builder does not appear to store the UIBarStyle
attribute of the NavigationBar. I want the bar to be black and
opaque. It totally ignores me if I use the IB Inspector to set this.
But I can get this to work programmatically, so there are clearly
still some kinks to work out in IB -- it's possible your code and NIB
are correct but the BETA has an issue.
If you want to send me more details offline I can offer some thoughts
-- I'm no SDK expert, but I have been coding with the official SDK
since it was released. Perhaps it will help (you could post details
here, but I didn't want to abuse the list if CocoaTouch is off topic).
Lastly, another frustrating item about the SDK is that the simulator
is not an _emulator_. It just replicates the iPhone's API (according
to the docs). This adds another layer of uncertainty about "bugs"...
but until Apple grants me a developer key, to the simulator I shall go!
Cheers,
George

Hi Folks,
I'm a new to the development of iPhone Apps since the official
launch of iPhone SDK
Currently I'm using the Beta-5 version of SDK on Mac OS-X Leopard
10.5.2 system
I have a problem while using the UITabBarController and UINavigation-
Controller objects when added to the window in the Interface Builder
Problem is I'm not able to add the UINavigation Controller Nib
object to be a View Controller of one of the TabBarItems of the
TabBarController in the nib file
Upon doing this it show some weird behavior like....
1) The Bar-Button actions are not getting properly called on the
navigation
Controller view ,application gets crashed with exit code 1
2) Sometimes the tab-Item images vanishes not able to view it
properly when the
application is launched in the simulator
All the above things work properly If I add the view controllers
view programmatic ally to the project...
I need the help on solving the above issues If any one knows it.
Your suggestions are most welcome.......
Best Regards,
Sachin
