问题:

Does anyone knows how to build a flip animation like the flipboard app? Thanks

回答1:

If you mean the page flip transition, have a look at the OpenGL transition class I wrote.

https://github.com/epatel/EPGLTransitionView

I added a couple of example transitions and one of them are a "page flip" transition.

回答2:

Have a look at FlipView, it tries to replicate Flipboard app for iPad

Some of the features implemented are:

Multiple flip (just click on last pagination if u r at first or second for multi-flip).
Views arrangement if orientation changed like Flipboard
Selection of random layout

Hopefully this link is of some help to you :D

I remember from watching an interview with the CEO saying that all the flipping boards and the animations are done using HTML5! I can not find it now sorry :(

I managed to find the non-broken link to FlipView example on github: https://github.com/Reefaq/FlipView

Hope it helps

I've been looking for the same for weeks. If you use the 'origami' transition in the ipad's photo app, you'll see that it has a very similar flipboard effect. Though someone with much more programming chops can probably give you the specifics, I think they use core animation. In it, you can define the anchor point and basically transform the uiview along the z axis.
