Hello, I've got a lovely OpenGLES code slice that renders up images for me. When I want to, I can call a function on it: -(UIImage *)renderToImage; That does a lot of rendering work and returns me an image.

Hello and thanks for looking at my question. I have an app that supports landscape orientation only (either left or right button). It launches in landscape-left.

I draw lines through all the points, meaning that the lines will change 30 times per second. I draw these lines to a CGLayer, which then is drawn to a UIView in the drawRect: method. I do this because I...

Hello Everyone, I'm currently using the snippet of code presented below to fire some methods every second. My app is running in the background. The problem is that if the computer wakes up after a sleep period the timer wants to retroactively fire all the methods it has missed. Similar issues come up if the user were to change the Syste...

Hey Everyone, With your he...
Hello. I'm coming from AS3 to Obj-C, and classes are confusing me.

I've searched but am unable to find a really clear explanation of what st...
