如何使用点击手势（iOS8 / Swift）在pageViewController上显示/隐藏状态栏 [英] How can I show/hide the status bar on a pageViewController using tap gesture (iOS8 / Swift)

问题描述

通过查看类似问题的所有解决方案，我一直试图通过点击手势显示/隐藏 statusBar 。

Looking through all the solutions given to similar questions, I have been trying to get the statusBar to show/hide with a tap gesture.

我设置在plist中查看基于控制器的状态栏外观= NO 。

我在我的 DataViewController （页面视图控制器）和 RootViewController 中尝试了以下代码：

I have tried the following code in my DataViewController (page view controller) AND in the RootViewController:

let app = UIApplication.sharedApplication()
app.setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.Fade)

它不起作用。

这是嵌入的一个 UITabBarController ，会有所作为吗？

This is embedded in a UITabBarController, would that make a difference?

另外，我能够从 RootViewController 中隐藏statusBar：

Also, I was able to get the following to hide the statusBar from the RootViewController:

override func prefersStatusBarHidden() -> Bool {
    return true
}

但是 DataViewController 甚至没有调用此函数，只能以这种方式永久隐藏它，而不是打开/关闭它。

But the DataViewController does not even call this function, and was only able to hide it permanently this way, rather than toggle it on/off.

任何想法？

推荐答案

我在代码中尝试过，一切都适合我。确保基于控制器的视图状态栏外观设置为否。并且无需覆盖 prefersStatusBarHidden（）。

I have tried it in code, everything works fine for me. Make sure that the View controller-based status bar appearance is Set to NO. And there is no needs to override prefersStatusBarHidden().
