迅速：合并不重叠的图像

Question

Every similar question I've seen relates to merging UIImage s by placing one image on top of the other. Instead, I'd like the images to be adjacent to each other. I have a rectangle image and a triangle image and I'd like to make a new image with the square on top and the triangle beneath it.

Answer 1

因此，创建一个合并图像大小的图像上下文，并使用drawInRect将图像渲染到其中。
