How to mimic UINavigation animation behavior when

问题:

I have a UIViewController that houses two UITableViews and swaps between the two. I'm wondering how can I implement the exact same animation behavior that a UINavigationController does when transitioning between these two UITableViews? (ie one tableView gets pushed off the screen left to right or right to left by the other tableView).

回答1:

// Set table 2 up offscreen as starting state
CGRect rect = tableView2.frame;
rect.origin.x = rect.size.width;
tableView2.frame = rect;

// fill in any details you need for the animation
[UIView beginAnimation:...

// move 1 left offscreen
rect = tableView1.frame;
rect.origin.x = -rect.size.width;
tableView1.frame = rect;

// bring 2 right onscreen
rect = tableView2.frame;
rect.origin.x = 0;
tableView2.frame = rect;

[UIView commitAnimation];

回答2:

Any reason you cant use two UIViewController:s?

If not you should be able to do it by animating the bounds property of both table views. You could probaby also do it by using a paged scroll view and just switch beteween pages.
