Swift: how could I draw lines inside UIImageView?

I use CGContext in a subclass of UIView to draw lines, it works fine when no other views in the ViewController on storyboard. However each time putting in an `UIImageView' with an image, it'd cover parts of the lines.

But I wanna draw several lines inside the UIImageView or inside the image. What should I do?

Would someone help me with it?

You cannot modify the drawing of an image view. If you want lines to appear in an image view, you must modify the image that it contains. Make a new image context, draw the image into it, draw the lines, extract the new image, and assign that image to the image view.
