如何在iOS 6中禁用带有自定义背景图像的导航栏的导航栏阴影？ [英] How do I disable the navigation bar shadow in iOS 6 for navigation bars with custom background images?

问题描述

在iOS 6中，即使您设置自定义背景图像，也会自动将阴影添加到导航栏。我很确定这不是iOS 5的情况，因为当我在iOS 5和6 sim中测试相同的代码时，阴影出现在iOS 6但不是5。

It seems in iOS 6, a drop shadow is automatically added to the navigation bar even when you set a custom background image. I'm pretty sure this wasn't the case with iOS 5 as when I test the same code in the iOS 5 and 6 sim, the shadow appears in iOS 6 but not 5.

有人对此有所了解吗？或者如何启用/禁用它？

Does anyone know anything about this? Or how to enable/disable it?

推荐答案

将其放入AppDelegate

Place this in your AppDelegate

[[UINavigationBar appearance] setShadowImage:[UIImage new]];
// is IOS 7 and later
[[UINavigationBar appearance] setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];

这就是为我做的。希望它有所帮助！

This is what did it for me. Hope it helps!

    UINavigationBar.appearance().shadowImage = UIImage()
    UINavigationBar.appearance().setBackgroundImage(UIImage(), forBarMetrics: .Default)
