Answer 1

您需要明确的Objective-C参考： @objc

@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage

    image = chosenImage

    self.performSegue(withIdentifier: "ShowEditView", sender: self)

    dismiss(animated: true, completion: nil)

}

Answer 2

我找到了解决方案。由于以下两个原因，导致出现此错误。

首先，我们需要调用此方法进行授权

授权码

func checkPermission() {

  let photoAuthorizationStatus = PHPhotoLibrary.authorizationStatus() switch photoAuthorizationStatus {

    case .authorized: print("Access is granted by user")

    case .notDetermined: PHPhotoLibrary.requestAuthorization({

      (newStatus) in print("status is \(newStatus)") if newStatus == PHAuthorizationStatus.authorized { / do stuff here */ print("success") }

    })

    case .restricted: / print("User do not have access to photo album.")

    case .denied: / print("User has denied the permission.")

  }

}

正确的方法调用 didFinishPickingMediaWithInfo

错误：

private func imagePickerController( picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

} 

对

@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

} 

希望此解决方案可以帮助您解决此错误。

如果对您有用，请别忘了将其标记为正确，这将有助于其他人找到正确的方法。

Answer 3

我找到了！它试图告诉您您没有“照片”的#import <Photos/Photos.h>授权。例如，需要在Objective-C中包括和请求这样的授权。

希望这可以节省您一些时间。我花了整整两天的时间进行调试！

[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {

    switch (status) {

        case PHAuthorizationStatusAuthorized:

            NSLog(@"PHAuthorizationStatusAuthorized");

            break;

        case PHAuthorizationStatusDenied:

            NSLog(@"PHAuthorizationStatusDenied");

            break;

        case PHAuthorizationStatusNotDetermined:

            NSLog(@"PHAuthorizationStatusNotDetermined");

            break;

        case PHAuthorizationStatusRestricted:

            NSLog(@"PHAuthorizationStatusRestricted");

            break;

    }

}];

我相信有人可以告诉您如何在Swift中执行相同的操作。
