swift - Change status bar color when navigation bar is hidden -

i want set black color(bar tint color) of status bar , white tint color when navigation bar hidden.

and want specific views. have tried this:

override func viewdidload()  {     super.viewdidload()      self.navigationcontroller?.setnavigationbarhidden(true, animated: true)      self.navigationcontroller?.navigationbar.barstyle = uibarstyle.black      self.navigationcontroller?.navigationbar.bartintcolor = uicolor.blackcolor()      self.navigationcontroller?.navigationbar.tintcolor = uicolor.whitecolor()  } 

i tried thing: set value no in p-list view controller-based status bar appearance.

if trying change status bar color, can use

uiapplication.sharedapplication().statusbarstyle = .lightcontent 

keep in mind cannot set status bar color other lightcontent , default (black). can set status bar light , throw element behind different color.

if want true way override color make black (default) or light, can try

override var preferredstatusbarstyle: uistatusbarstyle {     return .lightcontent } 

in view controllers want override. if need different background color, throw uilabel behind color , specify light content or default color.
