ios - UITabBar dissapear when dismiss UIImagePickerController -

-

in screenshot below, structure of storyboard uitabbarcontroller -> uinavigationcontroller -> uiviewcontroller. in uiviewcontroller, call .camera using uiimagepickercontroller in viewdidload. however, when users hit cancel inside camera, dismiss viewcontroller, , tab bar dissapears!

this codes dismiss:

func imagepickercontrollerdidcancel(picker: uiimagepickercontroller) {     dismissviewcontrolleranimated(true, completion: nil) }

enter image description here

enter image description here

edit: added calling of uiimagepickercontroller

override func viewdidload()     {          super.viewdidload()           let picker = uiimagepickercontroller()          picker.delegate = self          picker.sourcetype = .camera          presentviewcontroller(picker, animated: true, completion: nil)    }

try present imagepicker controller 'overcurrentcontext'

imagepicker.modalpresentationstyle = uimodalpresentationstyle.overcurrentcontext

or set in storyboard in uiviewcontroller, hope can you.
