How to render a view on the back face?

[mgruendler]

Hi Xiss,

How can I draw a view on the backside of the curling view? I'm not sure whether this is already implemented, but I couldn't find a mechanism. There is a backTexture in XBCurlView.h, but it seems that is not used. Do you have a plan to implement this feature or am I missing something?

Do you mean a double-sided page?

Yes, I mean a double page. I would like to implement a page flip of a comic book and would like to turn the page by curling. On the back side of the curled view I would like to render the next page of the comic.

Ok I understand. You made a correct guess on the backTexture, it is intended to be the texture that should be rendered on the backside of the page. But up till now, I have just created that variable! Since you're needing the feature, I will give priority to it.

Thanks.

That would be great!

I implemented an initial version of it. You just have to call the -[XBCurlView drawViewOnBackOfPage:] in order to draw a view on the back side of the curled page (the sample app is now doing that).

The code still needs some refactoring but the API should not change.

Ops, now I see I forgot to flip the texture horizontally! I am gonna solve it later.

I'm trying to use the drawViewOnBackOfPage function to draw the back of a playing card on the underneath of a view. So as to have a flexible two-sided card that I can peek at.

Code looks great, but does anyone have a working example I can see where drawViewOnBackOfPage is used?

Thanks!
