调用UIImagePickerController后如何隐藏状态栏? [英] How to hide status bar after calling UIImagePickerController?

问题描述

我想在iOS 10.2上调用UIImagePickerController后隐藏状态栏.

I want to hide the status bar after calling UIImagePickerController on iOS 10.2.

有几个问题的答案不适用于Swift 3.0.

There are several questions with answers that don't work for Swift 3.0.

建议的答案是:

• 扩展UINavigationController以覆盖preferredStatusBarHidden，因为UIImagePickerController是UINavigationController的子类.

所以我尝试了:

extension UINavigationController{
    open override var prefersStatusBarHidden: Bool{
        return true
    }
}

• 扩展UIImagePickerController以覆盖preferredsStatusBarHidden.

所以我尝试了:

extension UIImagePickerController{
    open override var prefersStatusBarHidden: Bool{
        return true
    }
}

• 创建并使用UIImagePicker的子类

所以我尝试了:

class MyImagePickerController: UIImagePickerController{
    override var prefersStatusBarHidden: Bool{
        return true
    }
}

以上解决方案均不适合我.

None of the above solutions work for me.

推荐答案

状态栏可以使用 UIImagePickerController 的以下扩展名永久隐藏:

The status bar can be permanently hidden with the following extension to UIImagePickerController :

extension UIImagePickerController {
    open override var childViewControllerForStatusBarHidden: UIViewController? {
        return nil
    }

    open override var prefersStatusBarHidden: Bool {
        return true
    }
}

这适用于iOS 10上的Swift 3.

This is working for Swift 3, on iOS 10.
