global ADBannerView in iPhone app
Is it possible with a standard UINavigationController-rooted app, to have a single ADBannerView visible at the bottom of the screen, below the view hierarchy? That is, without modifying each view-controller/view that can be pushed to the root UINavigationController, can I have a global ADBannerView be visible? I'm not sure how to set ...

Redrawing UIControls/UIButtons on iPhone in BubbleLevel example code
I'm confused about when -setNeedsDisplay should be called by me. As an example, for updating a button with different images between presses (toggling between the two), the example code from Apple shows -setImage being called on a UIButton. There's no call to -setNeedsDisplay that I can find after that, though. So do UIControl methods all...

I'm in the process of Localizing my app ready for the market. I'm going through all the .Xib files and have just found that 2 of the 10 Xib files are in their own fr.iproj folder.
