UIImage *bgImage = [[UIImage imageNamed:@"nav_other"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0) resizingMode:UIImageResizingModeStretch];
if (@available(iOS 13.0, *)) {

[barApp setBackgroundImage:bgImage];
self.navigationController.navigationBar.scrollEdgeAppearance = barApp;
self.navigationController.navigationBar.standardAppearance = barApp;

// Fallback on earlier versions
