I have a HMSegmentedControl with 4 segments. When it is selected, it should pop up view. And when the pop up dismissed, and trying to click on same segment index it should again show the pop up. By using following does not have any action on click of same segment index after pop up dissmissed.
segmetedControl.addTarget(self, action: "segmentedControlValueChanged:", forControlEvents: UIControlEvents.ValueChanged)
You set your target to fire just when the value change, so if you select the same segment the value will not change and the popover will not display, try to change the event to TouchUpInside, so it will be fired every time you touch inside the segment
segmentedControl.addTarget(self, action: #selector(segmentedControlValueChanged(_:)), for: .touchUpInside)
