ios - Back Button does not color accordingly (objective c) -

-

i’m working on iphone/ipad app has multiple navigation bar colours. in 1 part of app navigation bar has orange , in other part has purple. on start screen of app navigation bar hidden.

the colour of navigation bar, button , bar button set in prepareforsegue according segue identifier both sections of app.

uiimage *navbackgroundimage = [uiimage imagenamed:@"navigation-bar-orange.png"]; [[uinavigationbar appearance] setbackgroundimage:navbackgroundimage forbarmetrics:uibarmetricsdefault];  //change appearance of button uiimage *backbuttonimage = [[uiimage imagenamed:@"back-orange"] resizableimagewithcapinsets:uiedgeinsetsmake(0, 13, 0, 6)]; [[uibarbuttonitem appearance] setbackbuttonbackgroundimage:backbuttonimage forstate:uicontrolstatenormal barmetrics:uibarmetricsdefault];  //change appearance of standard navigation button uiimage *barbuttonimage = [[uiimage imagenamed:@"standard-orange"] resizableimagewithcapinsets:uiedgeinsetsmake(0, 6, 0, 6)]; [[uibarbuttonitem appearance] setbackgroundimage:barbuttonimage forstate:uicontrolstatenormal barmetrics:uibarmetricsdefault];  [[uinavigationbar appearance] settitletextattributes: [nsdictionary dictionarywithobjectsandkeys:                                                        [uicolor colorwithred:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], uitextattributetextcolor,                                                        [uicolor colorwithred:0.0 green:0.0 blue:0.0 alpha:0.8],uitextattributetextshadowcolor,                                                        [nsvalue valuewithuioffset:uioffsetmake(0, 1)],                                                        uitextattributetextshadowoffset,                                                        [uifont fontwithname:@"futura-condensedmedium" size:21.0], uitextattributefont, nil]];

when switching other part of application (going through segue again), navigation bar , standard bar button coloured correctly, button have colour of previous part of app. i’ve tried setting colour on several occasions in application (e.g. viewwillappear , viewdidload), problem still occurs.

how can fix problem , show correct button colour both sections of application? there maybe (better) way set different navigation bar colours?

visual example of occuring problem:

you correct. in fact, text set button in code behave similarly. button displayed gets settings previous view controller. shift settings one.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
