@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    image = chosenImage

我找到了这个解决方案。由于下面提到的这两个原因，我们得到了这个错误。

首先我们需要调用这个方法进行授权

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.")
  }
}

正确的方法调用方式didFinishPickingMediaWithInfo

错误的：

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

正确的

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

我希望这个解决方案能帮助你解决这个错误。

如果它对您有用，请不要忘记将其标记为正确，因此这将有助于其他人找到正确的方法。

我找到了！它试图告诉您您没有“照片”的授权您需要#import <Photos/Photos.h>在Objective-C中包含并请求授权，例如这样的。

希望这会为您节省一些时间。我花了整整两天时间调试这个！

[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你如何在 Swift 中做同样的事情。

尝试了一些组合响应，但没有取得多大成功。

使用 Swift 4，我发现我需要确保实现以下两项，以确保选择图像并将其放入选择器（注意发现扩展时遇到的“[discovery] 错误：

错误域=PlugInKit 代码=13“查询已取消”UserInfo={NSLocalizedDescription=查询已取消}”

消息仍然显示在控制台中，但它不会阻止您添加图像）。也许这是一条导致选择器被解雇的消息？

UIImagePickerController1)的委托(UIImagePickerControllerDelegate & UINavigationControllerDelegate)?需要明确添加UINavigationControllerDelegate作为协议之一：

class ViewController:UIViewController, UIImagePickerControllerDelegate, 
    UINavigationControllerDelegate { .... }.

2) 确保 info.plist 设置了Privacy - Photo library Usage Description键和字符串值。

当然，您需要确保创建 aUIImagePickerController并将其委托设置为等于selfin ViewDidLoad()：

class ViewController:UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate { 
    let imagePickerController = UIImagePickerController()
    override func viewDidLoad() {
        super.viewDidLoad()
        imagePickerController.delegate = self
    }
    ...
}

添加所需的权限（其他提及）

实现这个委托函数：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

    if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
        self.imgView.contentMode = .scaleAspectFit

我修复了这个问题，将下面的函数调用到 viewdidload 或 viewWillAppear 或 viewDidAppear 以检查您的应用程序的权限。

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")
                }
            })
            print("It is not determined until now")
        case .restricted:
            // same same
            print("User do not have access to photo album.")
        case .denied:
            // same same
            print("User has denied the permission.")
        }
    }

并且要使用上述方法，不要忘记import Photos在类的顶部添加。

2 - 已验证的权限；

This might not be the most directly helpful answer - but hopefully it will help! I'm 99% sure that this particular error message isn't actually pointing you to the real problem. I spent hours pulling my hair out over this same exact issue.

1) I had authorization for photos printing to the console when I'd launch my picker, 2) I could navigate and pick a photo easy enough, and 3) when I would return me to my view upon dismissing the picker, my button image wasn't updated with the new photo... and the only hint that I had to the problem was the exact same error message that you are receiving.

Turns out I was hard-coding a placeholder image in ViewWillAppear instead of ViewDidLoad. Every time the picker was dismissing, it was calling ViewWillAppear and replacing my chosen image with my hard coded image. I fixed that issue and sure enough - everything is working fine now... and I'm still seeing that error message every time I return from the picker.

I recommend looking somewhere other than the ImagePicker for your problem and you'll likely find it.

确保你是两个子类：UIImagePickerControllerDelegate, UINavigationControllerDelegate.

另外，请记住设置委托：

let picker = UIImagePickerController()
picker.allowsEditing = true
picker.sourceType = .photoLibrary
picker.delegate = self  //Don't forget this line!
self.present(picker, animated: true, completion: nil)

归功于此来源。

找到解决这个问题的方法花了我很长时间。看起来问题是找不到 UIImagePickerControllerDelegate 的函数 imagePickerController 。如果您正确设置了委托，并且在升级到 Swift 4 后它停止工作，那么问题可能是您没有使用自 Swift 4 以来必需的 @objc 使其对 Objective-C 可访问。

它一定要是：

@objc func imagePickerController(...

这个“Error Domain=PlugInKit Code=13”错误让很多人感到困惑，尽管它似乎是一个无害的苹果调试消息。我在获取我选择在我的 UI 中设置的图像时遇到了问题，并认为该错误是问题所在，但它有点微妙。

我将图像选择器控制器放在一个与呈现它的视图控制器分开的文件中。

MyViewController.swift

class MyViewController: UIViewController {
    @IBOutlet weak var profileImage: UIImageView!

    ...
}

extension MyViewController: ImagePickerDelegate {
    func didSelect(image: UIImage?) {
        self.profileImage.image = image
    }
}

ImagePicker.swift

open class ImagePicker: NSObject {
    ...
    private func pickerController(_ controller: UIImagePickerController, didSelect image: UIImage?) {
        controller.dismiss(animated: true, completion: {self.delegate?.didSelect(image: image)}
        )
    }
}

大多数教程和答案都将完成设置为 nil。但是，如果您将完成设置为 nil 并单独调用委托的 didSelect 方法，则该方法被调用但图像未设置，因此请确保使用关闭完成。

再说一次，我知道这个答案可能与原始问题没有直接关系，但我感觉很多人都是为了这个问题而来的，而给定的解决方案并没有帮助。原因是大多数给出答案的人都将他们的图像选择器控制器与他们的主视图控制器在同一个类中，因此不需要使用完成。

请按以下步骤检查：

导入照片

有权访问专辑：

func authorizeToAlbum(completion:@escaping (Bool)->Void) {

if PHPhotoLibrary.authorizationStatus() != .authorized {
    NSLog("Will request authorization")
    PHPhotoLibrary.requestAuthorization({ (status) in
        if status == .authorized {
            DispatchQueue.main.async(execute: {
                completion(true)
            })
        } else {
            DispatchQueue.main.async(execute: {
                completion(false)
            })
        }
    })

} else {
    DispatchQueue.main.async(execute: {
        completion(true)
    })
}
}

呈现 UIImagePickerController

self.authorizeToAlbum { (authorized) in
    if authorized == true {
        let picker = UIImagePickerController()
        picker.delegate = self
        picker.allowsEditing = false
        picker.sourceType = .photoLibrary

        self.present(picker, animated: true, completion: nil)
    }
}

关键步骤，确保委托方法严格遵循

// MARK: - UIImagePickerControllerDelegate Methods
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
    self.pickedImage = pickedImage
    if let finalImage = handleImage(originalImage: self.pickedImage!, maskImage: self.maskImage!) {
        self.imageView.image = finalImage
    }
}

dismiss(animated: true, completion: nil)
}

在我的情况下，我收到了这个错误，因为我在没有首先验证用户是否允许访问图像的情况下展示了一个图像选择器控制器。在我的代码的其他地方，用户已授予权限，所以我认为我需要做的就是导入照片。但是，由于他们“可能”没有在应用程序中授予权限，因此在我展示图像选择器控制器为我解决问题之前添加了此权限（也可以导入照片）。

// request photos permission if permission has not been granted
    if PHPhotoLibrary.authorizationStatus() != PHAuthorizationStatus.authorized {
        PHPhotoLibrary.requestAuthorization({ (status: PHAuthorizationStatus) in

        })
    }

如果这个答案看起来多余，我很抱歉，但我必须从几个不同的答案中拼凑起来才能让我的解决方案发挥作用。也许这会帮助其他使用 Swift 4 的人。

    } else {
        sourceImage = info[UIImagePickerControllerOriginalImage] as? UIImage
