Rotate UIImage in swift
<p>I want to rotate UIImage in clockwise direction. But my current code do not perform function accurate some time it rotate and some time its skip rotation. I want my UIImage will continuously rotate clockwise on my action button.
Here is my current code:</p>

<pre><code>imageView.image = imageView.image!.imageRotatedByDegrees(angle, flip: false)
angle = angle + 90
if angle &gt; 360{
    angle = 0
}
</code></pre>
