is there way make bar translucent in way thats similar setting uinavigationbar translucent?

it easy make work. have make pageviewcontroller taller, , place pagecontrol xib file. trick put pagecontrol in foreground (and other common controls) @ beginning, , update content of pagecontrol pageviewcontroller. here code:

- (void)viewdidload {     [super viewdidload];     // additional setup after loading view nib.      self.pagecontroller = [[uipageviewcontroller alloc] initwithtransitionstyle:uipageviewcontrollertransitionstylescroll navigationorientation:uipageviewcontrollernavigationorientationhorizontal options:nil];      self.pagecontroller.datasource = self;     // need cover control making frame taller (+ 37)     [[self.pagecontroller view] setframe:cgrectmake(0, 0, [[self view] bounds].size.width, [[self view] bounds].size.height + 37)];      tutorialpageviewcontroller *initialviewcontroller = [self viewcontrolleratindex:0];      nsarray *viewcontrollers = [nsarray arraywithobject:initialviewcontroller];      [self.pagecontroller setviewcontrollers:viewcontrollers direction:uipageviewcontrollernavigationdirectionforward animated:no completion:nil];      [self addchildviewcontroller:self.pagecontroller];     [[self view] addsubview:[self.pagecontroller view]];     [self.pagecontroller didmovetoparentviewcontroller:self];      // bring common controls foreground (they hidden since frame taller)     [self.view bringsubviewtofront:self.pcdots];     [self.view bringsubviewtofront:self.btnskip]; }  - (uiviewcontroller *)pageviewcontroller:(uipageviewcontroller *)pageviewcontroller viewcontrollerbeforeviewcontroller:(uiviewcontroller *)viewcontroller {      nsuinteger index = [(tutorialpageviewcontroller *)viewcontroller index];      [self.pcdots setcurrentpage:index];      if (index == 0) {         return nil;     }      index--;      return [self viewcontrolleratindex:index]; }  - (uiviewcontroller *)pageviewcontroller:(uipageviewcontroller *)pageviewcontroller viewcontrollerafterviewcontroller:(uiviewcontroller *)viewcontroller {      nsuinteger index = [(tutorialpageviewcontroller *)viewcontroller index];      [self.pcdots setcurrentpage:index];      index++;      if (index == 3) {         return nil;     }      return [self viewcontrolleratindex:index]; }  - (tutorialpageviewcontroller *)viewcontrolleratindex:(nsuinteger)index {      tutorialpageviewcontroller *childviewcontroller = [[tutorialpageviewcontroller alloc] initwithnibname:@"tutorialpageviewcontroller" bundle:nil];     childviewcontroller.index = index;      return childviewcontroller; }  - (nsinteger)presentationcountforpageviewcontroller:(uipageviewcontroller *)pageviewcontroller {     // number of items reflected in page indicator.     nsinteger tutorialsteps = 3;     [self.pcdots setnumberofpages:tutorialsteps];      return tutorialsteps; }  - (nsinteger)presentationindexforpageviewcontroller:(uipageviewcontroller *)pageviewcontroller {     // selected item reflected in page indicator.     return 0; }
