ios - Swift 请求用户访问照片库的权限

Question

我正在尝试访问照片库以在 swift 4 中导入个人资料图像。

但是我收到了这个错误:

This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data.

我以各种方式请求许可。

我尝试:

<key>NSPhotoLibraryUsageDescription</key>
    <string>this permission for profile photo only</string>

和代码:

let imagePicker = UIImagePickerController()
 override func viewDidLoad() {
     super.viewDidLoad()
     imagePicker.delegate = self
}
@objc func importUserImage() {
        print("import driver")

        imagePicker.sourceType = .photoLibrary
        imagePicker.allowsEditing = true
        self.present(imagePicker, animated: true)
    }

我试试

<key>NSPhotoLibraryAddUsageDescription</key>
    <string>this permission for profile photo only</string>

我什至尝试用代码来做到这一点

import UIKit
import Photos
import UserNotifications

class LoginViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        PHPhotoLibrary.requestAuthorization { (status) in
            // cruch here
        }
     }
}

我删除了应用程序并重新安装它，仍然崩溃

我是不是忘记了什么？或者我做错了什么？

试试这个:

转到您的plist。在最顶部，应该显示信息属性列表已选择此选项。然后右键单击并添加行输入隐私 - 照片库添加使用说明，然后在其右侧有一个值列，需要您输入文本，这就是用户的内容等着瞧。我希望这有帮助!
