如何创建一系列CGPoint（SWIFT）

Question

I have a line in my view(as UIImage). I want something to happen when an area is touched. How to create a range of CGPoints like with Integers?

I want to do something like this:

var range = CGPoint(x:155.0...160.0,y: 132.0...136.0)

And then check whether the touched point is in that range.

Sounds like what your really need is a GCRect .

let rect = CGRect(x: 155, y: 132, width: 5, height: 4)

Then, to know if your touched point is inside this rect, just do:

rect.contains(touchedPoint)
