iOS support

[felixfaire]

Is there any reason why the block does not officially support ios. I have just made a small change to the block.xml in my local version to enable iOS projects but i would be interested to know if there are any reasons why it is not already supported.

Thanks

Hi Felix,

Honestly we did not include it because we did not have the time to test on iOS...in theory it should work since we're relying completely on Cinder for this.

We use this library for our projects and we have not had the need for an OpenGL interface on iOS recently, but we can totally see the value.

If you can confirm that it works I'd be happy to accept a pull request on the cinderblock.xml revisions

Just started a project on iOS with poScene and had to fix a thing for the hittesting.
Found out that the viewport was double the size.
Had to change the following function void Node::setTransformation()

        const float scale =  ci::app::getWindow()->getContentScale();
        ci::Area viewport = ci::Area(ci::gl::getViewport().first, ci::gl::getViewport().second);

        viewport.x2 /= scale;
        viewport.y2 /= scale;

        mMatrix.set(ci::gl::getModelMatrix(), ci::gl::getProjectionMatrix(), viewport );

Hey @lab101 thanks for the catch, makes sense!

Do you want to issue a pull request? Otherwise I can update it on our side and push.

Hey Steve,

It was a quick fix feel free to change it into something better or faster.
Otherwise feel to copy this.
