How do I display Mathematics in the iphone app that I am making in swift?
For example, I can use MathJax to display mathematics in wordpress, thus is there a program that I can import mathematics to use in swift or how else can I do that?
So far, mine is very simplistic.
If all you're after is a higher baseline for the exponent and a lower baseline for the subscripts, use NSAttributedString and NSBaselineOffsetAttributeName.
Or if you really like MathJax, you could use MathJax (and UIWebViews instead of UILabels).

I have a sprite which I want to react to every part of the physics simulation except for gravity. I can't make it's dynamic property false otherwise it won't react to impulses and forces, but I still need gravity for the rest of the scene. How do I turn off gravity for one sprite?
spriteName.physicsBody.affectedByGravity = NO;

Does Direct2D support custom shaped windows? Say, drawing a circle over all other windows. If yes, could anyone give a link to an article or sample of such technique? Thanks.
Yep, it does.
Here is an article with examples, unfortunately, it goes in Russian, so use an online translator:

I have loaded an image in OpenGL by using texture. Now I want to draw same image after some time in future. So I keep texture for that image in my texture array. Now how can I load that image directly from that stored texture.
glBindTexture(GL_TEXTURE_…, textureID);
