Cannot invoke '+' with an argument list of type '(frame: CGRect)'

Question

I am trying to create a UIView from a CGRect frame. Every parameter in CGRectMake() are CGFloats.

var views:UIView = UIView(frame:CGRectMake(CGFloat(hotspotScroll.frame.size.width * i + 20), CGFloat(10),CGFloat(hotspotScroll.frame.size.width - 40), CGFloat(hotspotScroll.frame.size.height - 20)))

But it gives me an error:

Cannot invoke '+' with an argument list of type '(frame: CGRect)'

Why is that?

Answer 1

i需要成为*和+的CGFloat才能正确解决：

var views:UIView = UIView(frame:CGRectMake(CGFloat(hotspotScroll.frame.size.width * CGFloat(i) + 20), CGFloat(10),CGFloat(hotspotScroll.frame.size.width - 40), CGFloat(hotspotScroll.frame.size.height - 20)))
