在Swift中更改UISlider thumb的大小

Question

I am new to Swift. I have a UISlider and I want to make the size of the thumb of UISlider to smaller.

I tried to set a smaller image using code :

self.setThumbImage(UIImage(named: "progress_thumb"), forState: .Normal)

But it stretches the image.

Is it because of the image I have? How can I implement thumbRectForBounds here?

Please help me.

Thanks in advance.

我现在解决了这个问题，这是由于图像大小所致，当我将图像切成更小的尺寸时，它以我想要的确切尺寸正确显示在UISlider中。
