【问题描述】：

如何去掉tab顶部的黑线，

[self.tabBar setShadowImage:[UIImage new]];
self.tabBar.backgroundImage = [UIImage new];

ios13无效

【参考方案1】：

您需要为 iOS 13 使用新的UITabBarAppareance

if #available(iOS 13.0, *) 
    let appareance = UITabBarAppearance(barAppearance: tabBarController.tabBar.standardAppearance)
    appareance.shadowImage = nil
    appareance.shadowColor = nil
    tabBarController.tabBar.standardAppearance = appareance
 else 
    // Fallback on earlier versions.
    tabBarController.tabBar.shadowImage = UIImage()
