ios - UINavigationBar custom background image applied in one view controller and then affecting every single view controller in the app -


i working themes in app. each theme comes custom navigation bar. default, have applied custom navigation bar in appdelegate:

[uiapplication sharedapplication].statusbarstyle = uistatusbarstylelightcontent; uiimage *navbackgroundimage = [uiimage imagenamed:@"purplynav.png"]; [[uinavigationbar appearance] setbackgroundimage:navbackgroundimage forbarmetrics:uibarmetricsdefault];

if go specific table view controller in app , in viewwillappear, put:

if ([self.selectedtheme isequaltostring:@"blur"]) {     uiimage *navbackgroundimage = [uiimage imagenamed:@"pastelpinknav.png"];     [[uinavigationbar appearance] setbackgroundimage:navbackgroundimage forbarmetrics:uibarmetricsdefault]; }

the "pastelpinknav" gets applied every single navigation bar in app, though i'm setting in 1 table view controller.

how set navigation bar applies 1 view controller when set, still set default in app delegate when theme not set?

thanks in advance!

you have change again navigationbar image in viewwilldisappear

uiimage *navbackgroundimage = [uiimage imagenamed:@"purplynav.png"]; [[uinavigationbar appearance] setbackgroundimage:navbackgroundimage forbarmetrics:uibarmetricsdefault];

because using [uinavigationbar appearance] commonly changes uinavigationbar appearance.
