如何更改UIImagePickerController视图的UIStatusBarStyle文本颜色

Question

尝试更改UIStatusBarStyle文字颜色的UIImagePickerController。尝试以下方法：

imagePicker.navigationBar.isTranslucent = false
imagePicker.navigationBar.barTintColor = .darkGray
imagePicker.navigationBar.tintColor = .white
imagePicker.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white]

This回答显示即使是运营商徽标和UIStatusBarStyle也会按照指定更改颜色。但它并没有改变。是否还有其他事情可以尝试在UIStatusBarStyle中更改UIImagePicker文字颜色？

尝试使用以下代码，该代码适用于其他UIViewController s

imagePicker.preferredStatusBarStyle = UIStatusBarStyle.lightContent
imagePicker.setNeedsStatusBarAppearanceUpdate()

但不工作..请帮忙。谢谢。

Answer 1

这是我的代码 - UIImagePIckerController的一个简单子类。

public class ImagePickerController: UIImagePickerController {

    override public func viewDidLoad() {
        super.viewDidLoad()
    }

    override public func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    override public var preferredStatusBarStyle : UIStatusBarStyle {
        return .lightContent
    }
}

=======  将UINavigationControllerDelegate，UIImagePickerControllerDelegate添加到您的

@interface yourController（）＆lt;＆gt;

=======

imagePickerController.delegate = self;

=======

- （void）navigationController：（UINavigationController *）navigationController willShowViewController：（UIViewController *）viewController animated：（BOOL）animated {     [[UIApplication sharedApplication] setStatusBarStyle：UIStatusBarStyleLightContent]; }
