IOS pagecurl effect Summary

Http://blog.csdn.net/favormm/article/details/6592634

Currently, Apple does not provide pagecurl APIs for the latest SDK (4.3). To achieve page turning like Google map app, you can only achieve it by yourself.

Summarize the resources I have collected.

IBook paging effect with private APIs: http://blog.steventroughtonsmith.com/2010/02/apples-ibooks-dynamic-page-curl.html

With opengles implementation of a flip effect: http://wdnuon.blogspot.com/2010/05/implementing-ibooks-page-curling-using.html on this basis can develop their own pagecurl.

Using coreanimation to achieve the paging effect, a completely 2D simulation effect: http://github.com/brow/leaves later enhanced http://github.com/ole/leaves

The first private API cannot be applied to the appstore, but the effect is the best. The second one is very good, but it cannot be changed as the first one moves with the finger. The third method works well, but it does not seem like turning pages.

So I recommend the second method. If we change the orientation of the virtual cone with the movement of our fingers, will the effect be the same as that of the first one? I have not studied it in depth. People with time and energy will study it.

Why does apple not publish such APIs? There will be no security factors. You cannot figure it out !!!
