我知道这个问题已经在这个网站上得到了解答但我尝试了代码并收到错误请帮我在收藏视图中显示我的相机卷（我知道我必须在info.plist中添加照片用法请Just专注于我的代码谢谢！）
这是我的视图控制器代码
class translateViewController: UIViewController , UINavigationControllerDelegate , UIImagePickerControllerDelegate , UICollectionViewDataSource, UICollectionViewDelegate {
@IBOutlet var myimageView: UIImageView!
@IBAction func importImage(_ sender: Any) {
let image = UIImagePickerController()
image.delegate = self
image.sourceType = UIImagePickerControllerSourceType.photoLibrary
image.allowsEditing = false
self.present(image , animated: true)
{
}
}
@IBOutlet weak var cameraRollCollectionView: UICollectionView!
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage{
myimageView.image = image
}
else {
print("Error")
}
self.dismiss(animated: true, completion: nil)
}
@IBOutlet var translatebackgroundimg: UIImageView!
@IBOutlet var translatefrontimg: UIImageView!
var assetCollection: PHAssetCollection!
var photosAsset: PHFetchResult<AnyObject>!
var assetThumbnailSize: CGSize!
override func viewDidLoad() {
super.viewDidLoad()
let fetchOptions = PHFetchOptions()
let collection:PHFetchResult = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: fetchOptions)
if let first_Obj:AnyObject = collection.firstObject{
//found the album
self.assetCollection = first_Obj as! PHAssetCollection
}

self.translatebackgroundimg.addSubview(blurView)
// Do any additional setup after loading the view.
translatefrontimg.image = UIImage(named: "Translate.png")

override func viewDidAppear(_ animated: Bool) {

let blurView = UIVisualEffectView(effect: blurEffect)
blurView.frame = translatebackgroundimg.bounds
translatebackgroundimg.addSubview(blurView)
translatebackgroundimg.frame = self.view.bounds
}
override func viewWillAppear(_ animated: Bool) {

func numberOfSections(in collectionView: UICollectionView) -> Int {

return 1

var count: Int = 0
if(self.photosAsset != nil){

}
return count;
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cameraCell", for: indexPath as IndexPath)
//Modify the cell
let asset: PHAsset = self.photosAsset[indexPath.item] as! PHAsset
PHImageManager.default().requestImage(for: asset, targetSize: self.assetThumbnailSize, contentMode: .aspectFill, options: nil, resultHandler: {(result, info)in
if result != nil {
cameraCell.userImage.image = result

return cell
}
// MARK: - UICollectionViewDelegateFlowLayout methods

}
// UIImagePickerControllerDelegate Methods
func imagePickerControllerDidCancel(_ picker: UIImagePickerController){

这是我的CollectionViewCell代码
class cameraCell: UICollectionViewCell , UIImagePickerControllerDelegate {
@IBOutlet weak var userImage: UIImageView!
func configurecell(image: UIImage){
userImage.image = image
}
}
