旋转的UIImageView不断 [英] Spin UIImageView continuously

问题描述

我有一个问题，而试图用球的形象的UIImageView 连续旋转中。我想这个球在其中心轴线持续旋转。
我一直在使用 CGAffineTransform 尝试，但没有奏效。

I am having a problem while trying to rotate UIImageview continuously with a ball's image inside. I would like this ball to spin continuously on its center axis. I have tried using CGAffineTransform but it didn't work.

请帮帮忙！

推荐答案

如果您使用转换，因为它应该工作：

It should work if you use transforms as:

itemToRotate.transform = CGAffineTransformRotate(itemToRotate.transform, currentAngle);
