在iOS7中使用UITabbarController的Split View Controller问题 [英] Issue with Split View Controller with UITabbarController in iOS7

问题描述

我在UITabbarController中使用UISplitViewController。现在的问题是，当我尝试将tabbar的半透明属性设置为NO时，它会在标签栏上方显示一个额外的栏，如下图所示。

I am using UISplitViewController inside UITabbarController. Now the problem is that when I am trying to set translucent property of tabbar to NO then it shows an additional bar above the tab bar as shown in picture below.

您对该问题的帮助将是非常感谢。

Your help regarding the problem will be highly appreciated.

谢谢

推荐答案

只需在master的 viewDidLoad 上添加此代码：

Just add this code on master's viewDidLoad:

self.splitViewController?.extendedLayoutIncludesOpaqueBars = true
