ios - How to animate tabbar badge count in swift -


i want animate badge count on tabbar bouncing animation . has implemented native uitabbarcontroller . not using third party class adding uitabbarcontroller in project.

i thing before share code first create 2 functions first 1 :

func loopthrowviews(view:uiview){     subview in (view.subviews){         let type = string(describing: type(of: subview))         print(type)         if type == "_uibadgeview" {             print("this badgeview")             animateview(view: subview)         }          else {             loopthrowviews(view:subview)         }      } }

this function take view , loop throw subviews until find badge view it's call animate method 1 

  func animateview(view:uiview){ let shakeanimation = cabasicanimation(keypath: "position") shakeanimation.duration = 0.05 shakeanimation.repeatcount = 50 shakeanimation.autoreverses = true shakeanimation.fromvalue = nsvalue(cgpoint: cgpoint(x:view.center.x - 10, y:view.center.y)) shakeanimation.tovalue = nsvalue(cgpoint: cgpoint(x:view.center.x + 10, y:view.center.y)) view.layer.add(shakeanimation, forkey: "position") }

you can replace code @ method own animation

all need call method when ever want animate badge 

 loopthrowviews(view: self.tabbarcontroller!.tabbar)

the result
