如何在iOS 15＆＃x2B中修复Navbar UiimagePickerController保持透明
设备使用时，我对uiimagePickerController有问题
iOS 15 =“ https://i.sstatic.net/mdhab.jpg” alt =“在此处输入图像说明”> 我的期望是Navbar像15岁以下的iOS设备一样保持白色 我使用了此方法，但是它不起作用，有没有办法解决此问题？
let picker = UIImagePickerController()
picker.sourceType = .photoLibrary
picker.delegate = self
picker.modalPresentationStyle = .overCurrentContext
if #available(iOS 13.0, *) {
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .white
appearance.shadowColor = .white
appearance.shadowImage = UIImage()
picker.navigationBar.standardAppearance = appearance
picker.navigationBar.scrollEdgeAppearance = appearance
}
viewController.present(picker, animated: true, completion: nil)
谢谢
I have a problem with UIImagePickerController when used by iOS 15 device because the navigation bar has a transparent background,
my expectation is the navbar to stay white like on ios devices below 15
I've used this method but it doesn't work, is there a way to fix this issue?
let picker = UIImagePickerController()
picker.sourceType = .photoLibrary
picker.delegate = self
picker.modalPresentationStyle = .overCurrentContext
if #available(iOS 13.0, *) {
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .white
appearance.shadowColor = .white
appearance.shadowImage = UIImage()
picker.navigationBar.standardAppearance = appearance
picker.navigationBar.scrollEdgeAppearance = appearance
}
viewController.present(picker, animated: true, completion: nil)
Thank you

根据 Apple论坛上的一些旧问题它的导航栏似乎参考
picker.navigationbar.standardappearance无法真正更改Picker的外观，唯一不幸的解决方案是为所有uinavigationbars全局更改外观，通过同样设置其外观：也可以 ：检查您是否没有偶然地在代码中的某个地方修改全局显示。
希望它可以帮助您，即使它不是最佳解决方案。
According to some old question on Apple forum regarding
UIImagePickerControllerand its navigationBar it seems that referencingpicker.navigationBar.standardAppearancecannot really change picker appearence and the only unfortunate solution is to globally change appearence for allUINavigationBarsby setting its appearence likewise:Also check if you are not modifying the global appearence somewhere in your code by accident.
Hopefully it helps you, even though it is propably not optimal solution.
