Curled View Cut off In Simple Curl

[barronM]

First of all, thank you so much for your excellent XBPageCurl class. This is awesome.

I'm not sure if this is an issue, or whether it's something I've just been unable to figure out:

I'm curling a view that does not cover the full screen. It is a subview that is effectively surrounded on all sides by a margin. The curl works, but when I curl the page with the cylinder at an angle, any part of the curled "page" that falls outside of the bounds of the XBCurlView is cut off. This seems reasonable, but when I try to change the size of the XBCurlView instance before calling "curlView: cylinderPosition: cylinderAngle: cylinderRadius: animatedWithDuration:" it offsets the curledView.

Is there another way to do this, or this functionality not supported yet?

Thank you so much!

Hi there. The curl animation happens inside a view where OpenGL rendering happens, and it cannot happen outside the view bounds. When you call curlView... it will create a XBCurlView (which renders in OpenGL) with the same frame of the view you pass in the parameter.

XBPageCurl always creates the page triangle mesh of the same size of the view, so this is still not possible to achieve. We need to add one more parameter to these methods to specify the frame of the page inside of the XBCurlView. This way, we'll be able to create a large XBCurlView and curl only a subset of it, which is what you want. I will look into this later.

Thanks for the feature request.

Hey xissburg, thanks for the reply. That makes sense -- I tried to play around with the XBCurlView frame and curlView parameter separately, but was not able to get it working. Would love to have this feature, looking forward to seeing it in action someday!
