ios - 类型 'PHPhotoLibrary' 的值没有成员 'presentLimitedLibraryPicker' - Xcode 11.3.1

Question

Xcode 11.3.1

使用未声明的类型“PHAccessLevel”

“PHPhotoLibrary”类型的值没有成员“presentLimitedLibraryPicker”

仅当我尝试针对实际设备进行编译时，才会出现此错误。已尝试使用 iOS 14 和 iOS 13 设备。代码使用模拟器进行编译。 尝试清理构建、清理派生数据以及关闭并重新打开项目。但运气不好

import Photos
import PhotosUI

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        if #available(iOS 14, *) {
            let accessLevel: PHAccessLevel = .readWrite
            let authorizationStatus  = PHPhotoLibrary.authorizationStatus(for: accessLevel)
            switch authorizationStatus {
            case .limited:
                var testVc = UIViewController()
                PHPhotoLibrary.shared().presentLimitedLibraryPicker(from: testVc)
                //callBack(authorizationStatusAuthorised)
            case .authorized:
                //callBack(authorizationStatusAuthorised)
                var te = ""
            default:
                //callBack("")
                var test = ""
            }
        }
    }
}

Answer 1

Value of type 'PHPhotoLibrary' has no member 'presentLimitedLibraryPicker'

当我使用 import Photos 作为解决方法尝试使用单个 import PhotosUI (而不是 import Photos import PhotosUI )时，出现此错误

import PhotosUI
