ios - Perform segue to another Navigation Controller without showing Tab Bar -

i have root tab host controller 2 navigation controller tab siblings: (1) nearby stops , (2) saved stops. each of these has view controller respectively.

i perform segue 1 of sibling view controllers navigation controller stop schedule view controller embedded in it, following requirements:

1. the root tab bar should not show @ bottom of view controller
2. i need pass stop object view controller before performing segue

storyboard:

currently, performing segue way, though tab bar remains on stop schedule view controller when shouldn't.

func showstopschedule(stop: stop) {     let stopschedulecontroller = self.storyboard?.instantiateviewcontrollerwithidentifier("stopscheduleviewcontroller") as! stopscheduleviewcontroller      stopschedulecontroller.stop = stop    // pass data object      self.navigationcontroller?.pushviewcontroller(stopschedulecontroller, animated: true) } 

you can set hidden property of tab bar when stop schedule view controller displayed , unhide tab bar before view controller disappears

override func viewwillappear(animated: bool) {     super.viewwillappear(animated)     self.tabbarcontroller?.tabbar.hidden=true }  override func viewwilldisappear(animated: bool) {     super.viewwilldisappear(animated)     self.tabbarcontroller?.tabbar.hidden=false } 

update: animate transition can use this:

class stopviewcontroller: uiviewcontroller {      var barframe:cgrect?      override func viewdidload() {         super.viewdidload()          // additional setup after loading view.     }      override func viewwillappear(animated: bool) {          super.viewwillappear(animated)         // self.tabbarcontroller?.tabbar.hidden=true         if  let tabbar=self.tabbarcontroller?.tabbar {            self.barframe=tabbar.frame             uiview.animatewithduration(0.3, animations: { () -> void in                let newbarframe=cgrectmake(self.barframe!.origin.x, self.view.frame.size.height, self.barframe!.size.width, self.barframe!.size.height)                tabbar.frame=newbarframe             }, completion: { (bool) -> void in                 tabbar.hidden=true             })          }     }      override func viewwilldisappear(animated: bool) {         super.viewwilldisappear(animated)         self.tabbarcontroller?.tabbar.hidden=false;         if self.barframe != nil {             uiview.animatewithduration(0.3, animations: { () -> void in                 let newbarframe=cgrectmake(self.barframe!.origin.x, self.view.frame.size.height-self.barframe!.size.height, self.view.frame.size.width, self.barframe!.size.height)                 self.tabbarcontroller?.tabbar.frame=newbarframe             })          }     } }
