如何在不制作新UIImageView的情况下绘制新图像

Question

I have a character in an iPod Touch game I am making that moves around the screen. That I have under control... However I want him able to shoot fireballs, and I don't want to have to make a new UIImageView for every fire ball he shoots. I have the image and everything... I think i need to use quartz core or openGL ES, but I can't make sense of the apple documentation.

另一种选择是在您的视图中实现drawRect ，并在那里绘制火球。
