iphone - Setting UITabBarIcon tint when unselected -

i trying set icons of uitabbaritem, not working. way, i'm using xcode 5 beta project.

@implementation appdelegate  - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     {         [[uitabbaritem appearance] settitletextattributes:[nsdictionary dictionarywithobjectsandkeys:[uicolor whitecolor], nsforegroundcolorattributename, nil] forstate:uicontrolstatenormal];         uiimage *tabbarbackground = [uiimage imagenamed:@"tabbar.png"];         [[uitabbar appearance] setbackgroundimage:tabbarbackground];         [[uitabbar appearance] setselectionindicatorimage:[uiimage imagenamed:@"tabbar_selected.png"]];         [[uitabbar appearance] settintcolor:[uicolor whitecolor]];     }     return yes; } 

i trying icons white when both selected , unselected, remaining gray in unselected state.

edit

i tried doing this, im getting error "expression result unused"

uitabbarcontroller *tabbarcontroller = (uitabbarcontroller *)self.window.rootviewcontroller;         uitabbar *tabbar = tabbarcontroller.tabbar;         uitabbaritem *tabbaritem1 = [tabbar.items objectatindex:0];         tabbaritem1.title = @"home";         uiimage *graph = [uiimage imagenamed:@"graph.png"];         [tabbaritem1 initwithtitle:(nsstring *)@"hello" image:(uiimage *)graph selectedimage:(uiimage *)graph]; 

tintcolor sets tint color of background, can't see if use custom background image. if don't want have system default gradient have use setfinishedselectedimage:withfinishedunselectedimage: , set white image both of them.

like this:

uiimage *selectedimage = ... uiimage *unselectedimage = selectedimage; [tabbaritem setfinishedselectedimage:selectedimage withfinishedunselectedimage:unselectedimage]; 

if setting images in storyboard can iterate on existing uitabbaritems , change images.

put application:didfinishlaunchingwithoptions:

uitabbarcontroller *tabbarcontroller = (uitabbarcontroller *)self.window.rootviewcontroller; nsassert([tabbarcontroller iskindofclass:[uitabbarcontroller class]], @"self.window.rootviewcontroller must tabbarcontroller"); (uiviewcontroller *viewcontroller in tabbarcontroller.viewcontrollers) {     uitabbaritem *tabbaritem = viewcontroller.tabbaritem;     uiimage *tabimage = tabbaritem.image;     [tabbaritem setfinishedselectedimage:tabimage withfinishedunselectedimage:tabimage]; }
