iOS GLKit，在GLKView中绘制文本

Question

I'm using GLKit to create a game on the iPhone. setting up the GLKit context and drawing sprites on it isn't that hard but when I try to add text to it, it seems impossible to do. I have searched around for an answer but all the solutions I tried to find can't be mixed in GLKView.

What is the best practice to render text in the GLKView?

Answer 1

从最简单的意义上说，“最佳”是制作一个UILabel，设置所需的所有文本和背景参数，然后从标签图层创建UIImage来创建或更新纹理。

Answer 2

The simplest answer is sometimes the best. While the documentation has some words discouraging compositing between GLES and Quartz, it can work quite well to overlay a GLKView with a standard UIKit view, such as a UITextView. You will, of course, want to confirm the performance impact on your least capable supported hardware / software configuration, but on a newer configuration, total rendering time remained below 1ms for an animating model while scrolling an overlaid UITextView with a clear background, set to be non-opaque.
