Objective

UIView not like UIButton plus click events will have a click effect, the experience is much worse, here through customization and expansion to achieve similar uibutton effect.

Body

First, add click event for UIView

Extension UIView {

  func addonclicklistener (Target:anyobject, action:selector) {Let
    gr = UITapGestureRecognizer (Target:target, action:action)
    gr.numberoftapsrequired = 1
    userinteractionenabled = True
    Addgesturerecognizer (gr)
  }

}

Second, add click Effect for UIView

Class Uivieweffect:uiview {

  override func Touchesbegan (touches:set<uitouch>, withevent event:uievent?) {
    backgroundcolor = Uicolor.grouptableviewbackgroundcolor ()
  }

  override Func touchescancelled (touches: Set<uitouch>?, Withevent event:uievent?) {
    uiview.animatewithduration (0.15, animations: {()-> Void in
      self.backgroundcolor = Uicolor.clearcolor () c7/>})
  }

  override func touchesended (touches:set<uitouch>, withevent event:uievent?) {
    uiview.animatewithduration (0.15, animations: {()-> Void in
      self.backgroundcolor = Uicolor.clearcolor ( )
    })
  }
}

Here everyone can change their own click effect, if it is Uiimageview can be changed to click Change Transparency.
