[移动开发]Xcode升级到13导致UINavigationBar错乱

最近iPhone13发布，iOS15系统发布，自己脑残升级了Xcode到最新版13，导致UINavigationBar的背景失效。
解决办法：

if (@available(iOS 13.0, *)) {
        UINavigationBarAppearance *appearance = [UINavigationBarAppearance new];
        //设置背景色
        appearance.backgroundColor = APP_NAVIGATIONBAR_TINTCOLOR;
        //设置标题颜色
        appearance.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor whiteColor]};
        //设置返回按键和返回字体为白色
        self.navigationBar.tintColor=[UIColor whiteColor];
        self.navigationBar.standardAppearance = appearance;
        self.navigationBar.scrollEdgeAppearance = appearance;
    } else {

        UINavigationBar *bar = [UINavigationBar appearance];
              [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"nav"] forBarMetrics:UIBarMetricsDefault];
              bar.barTintColor = APP_NAVIGATIONBAR_TINTCOLOR;
              bar.tintColor = [UIColor whiteColor];
              [self.navigationController.navigationBar setTranslucent:YES];
              NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                 [UIFont systemFontOfSize:0.0001],NSFontAttributeName,nil];
                 [[UIBarButtonItem appearance] setTitleTextAttributes:attributes forState:UIControlStateNormal];
    }
