Ever since the new iOS 15 update, the NavBar and Bottom Button Bar is transparent and can not have a color set. Does anyone have a fix?

Replace lines 269-273 in BT_viewController.m with the snippet below, to (hopefully!) fix the NavBar transparency issues: if([[BT_strings getStyleValueForScreen:self.screenData nameOfProperty:@"navBarStyle" defaultValue:@""] isEqualToString:@"solid"]){ if (@available(iOS 13.0, *)) { UINavigationBarAppearance *navBarAppearance = [[UINavigationBarAppearance alloc] init]; [navBarAppearance configureWithOpaqueBackground]; navBarAppearance.backgroundColor = [BT_color getColorFromHexString:tmpBarBackgroundColor]; [self.navigationController.navigationBar setScrollEdgeAppearance:navBarAppearance]; [self.navigationController.navigationBar setStandardAppearance:navBarAppearance]; } else { [self.navigationController.navigationBar setTranslucent:FALSE]; [self.navigationController.navigationBar setBarStyle:UIBarStyleBlackOpaque]; [self.navigationController.navigationBar setBarTintColor:[BT_color getColorFromHexString:tmpBarBackgroundColor]]; } } (Did the Bottom Button Bar have a color set previously, or did it inherit the NavBar color?)

Awesome. That code appears to have fixed the NavBar at the top. Sorry, I probably should have been more clear on the Bottom Button Bar/Menu. It could not be assigned/inherit a color. Ever since the update, it has been permanently made transparent instead of white.

Great! Glad to know that helped! Here's a snippet to fix the tab bar being transparent in iOS 15: //make the tab bar behave like before iOS 15 changes if (@available(iOS 15.0, *)) { UITabBarAppearance *tabBarAppearance = [[UITabBarAppearance alloc] init]; [tabBarAppearance configureWithOpaqueBackground]; //customize the tab bar color... if(self.rootTheme != nil){ NSString *tabBarColor = [BT_strings getStyleValueForScreen:self.rootTheme nameOfProperty:@"tabBarColor" defaultValue:@""]; if([tabBarColor length] > 1){ UIColor *tmpColor = [BT_color getColorFromHexString:tabBarColor]; [tabBarAppearance setBackgroundColor:tmpColor]; } } [[self.rootTabBarController tabBar] setStandardAppearance:tabBarAppearance]; [[self.rootTabBarController tabBar] setScrollEdgeAppearance:tabBarAppearance]; } Just place it in BT_application.m around line 308. (Alternatively, I did add both the patches to the latest version of the Buzztouch iOS core... so you can re-download your application from your control panel to get these patches. :)

Awesome, worked perfectly. A god sent.
