iPhone CATransition adds a fade to the start and end of any animation?

Question

So I am just beginning recently developing some simple apps for the iphone. I will say that I am fairly sure I don\'t have a strong understanding of programming for multiple

I have never been able to find a solution to this problem, but I can offer a reasonable workaround. What's happening is it isn't fading to white, but fading to transparent, and the window background (or whatever view is behind) is white. There are a couple ways to get around this:

1. Change the window background color. If both views you're fading between have the same solid background color, then this will look pretty good.

2. Don't render a background in each view ("MenuView," for example), but rather have a shared background view that's under those views at all times.

Note that this will not work in all circumstances -- grouped UITableViews, for example, are always completely opaque.

(As I side note, I assume that you aren't build a navigation-based application, in which case all the animation should be handled automatically.)

You also might want to consider the looking into the UIView method setAnimationTransition:forView:cache: if you haven't already as another way to transition between views (although it cannot do a sliding animation, if you are set on that).
