iBook page flip transition

Question

I'm trying recreate iBook like transition for pages in landscape mode for an pdf reader app. I only need the animation, not the, touch handling like iBook app; the user with a simple swipe turn the page. I have tried different sample code, including Leaves, but I can't find anything simple. Can Anyone help me to create this simple animation, or there's a simple way to recreate iBook transition?

Leaves is an excellent project that is easy and simple to include in projects. – Clerk

There's a way to modify Leaves to only do the transition between pages without tracking touches? – Lozar

Leaves also support landscape orientation with two pages? – Lozar

there are different forks of Leaves which include landscape with 2 pages: github.com/ansani/leaves – Clerk

Answer 1

Ole Begemann has done something like this. You can find the project here on GitHub.

Ole also writes a superb blog summary of some of the best developer links and tutorials around. Well worth subscribing to!

I don't want to use the Leaves framework because I only need the animation, I don't need to track the touch of the user. I only need the animation of the flipping page. – Lozar

It shouldn't be too hard to use it without the touch tracking. You could remove that part of the code and replace it with an animation curve. – Crosscheck

Answer 2

Look at the UIView documentation for animation types available. Here is what I'd use:

UIViewAnimationOptions animation;
if (pageNumberLower) {
    animation = UIViewAnimationOptionTransitionCurlDown;
} else {
    animation = UIViewAnimationOptionTransitionCurlUp;
}

[UIView transitionWithView:myChangingView
                  duration:0.5
                   options:animation
                animations:^{ CHANGE PAGE HERE }
                completion:NULL];

This certainly looks nice, but is nothing compared to the iBook page flip animation. – Midgett
