ios - UINavigationBar appearance proxy when contained in UIPopoverController -

i i'm doing supposed work in ios7 , 8, reason doesn't. want customize navigation bar properties via appearance proxy , want applied navigation bars ones within uipopover.

so, first step following:

uinavigationbar *appearance = [uinavigationbar appearance]; appearance.bartintcolor = [uicolor redcolor]; appearance.titletextattributes = @{ nsforegroundcolorattributename: [uicolor yellowcolor] };

this supposed create navigation bars reddish yellowish title. works in ios8. work in ios7. reason when view controller beingness presented within uipopovercontroller - gets default appearance.

this how nowadays popover (nothing fancy - standard sample code):

uiviewcontroller *vc = [self.storyboard instantiateviewcontrollerwithidentifier:@"vc2"]; vc.title = @"view controller 2"; uinavigationcontroller *nav = [[uinavigationcontroller alloc] initwithrootviewcontroller:vc]; self.popover = [[uipopovercontroller alloc] initwithcontentviewcontroller:nav]; [self.popover presentpopoverfromrect:cgrectmake(100, 100, 100, 100) inview:self.view permittedarrowdirections:0 animated:yes];

ok, decided seek appearancewhencontainedin , explicitly set appearance there. added next code initial appearance customization:

appearance = [uinavigationbar appearancewhencontainedin:[uipopovercontroller class], nil]; appearance.bartintcolor = [uicolor greencolor]; appearance.titletextattributes = @{ nsforegroundcolorattributename: [uicolor bluecolor] };

now. reason lastly code doesn't impact anything. in ios8 navigation bars within uipopovercontrollers still reddish + yellow, not greenish + blue, , ios7 still uses default appearance.

what doing wrong here?

here link test project: https://dl.dropboxusercontent.com/u/6402890/testappearance.zip

for ios 8

ns_class_available_ios(8_0) @interface uipopoverpresentationcontroller : uipresentationcontroller

using next worked me. navigation controller contained in uipopoverpresentationcontroller.

appearance = [uinavigationbar appearancewhencontainedin:[uipopoverpresentationcontroller class], nil];

for ios 7

appearance = [uinavigationbar appearancewhencontainedin:[uipopovercontroller class], nil]; uinavigationcontroller *nav = [[uinavigationcontroller alloc] initwithrootviewcontroller:vc]; nav.navigationbar.barstyle = uibarstyleblack;

if navigation controller loaded storyboard, barstyle needed set uibarstyleblack in storyboard.
