iOS8 Swift: Navigation and Tool Bars don't show up -

-

navigationbar , toolbar not showing in simulator. went through similar questions posted in forum , included learnt answers. still i'm unable figure out why bars not shown. included following lines viewwillappear()

//show toolbar , navbar

self.navigationcontroller?.setnavigationbarhidden(false, animated: true) self.navigationcontroller?.settoolbarhidden(false, animated: true)

below screenshot of storyboard. storyboard

the simulator screenshot appears simulator

i reach view controller tableviewcontroller (which embedded in tabbarcontroller) programmatically, following code

var nextcontroller = imagepickviewcontroller()

nextcontroller = self.storyboard?.instantiateviewcontrollerwithidentifier("imagepicker") as! imagepickviewcontroller

self.presentviewcontroller(nextcontroller, animated: true, completion: nil)

any appreciated. please let me know if additional information required.

thanks in advance hari

thank james udacity. posting diagnosis.

the toolbars didn't show because used presentviewcontroller. embedded navigation controller bypassed , imagepickviewcontroller presented directly.

solution start navigation controller using segueidentifier. added segue tableviewcontroller navigation controller (of imagepickviewcontroller). in attribute inspector segue, set identifier "startimagepicker". in tableviewcontroller code, start imagepickviewcontroller calling performseguewithidentifier -

self.performseguewithidentifier("startimagepicker", sender: self)

thanks hari
