我使用ImagePickerController,抓取个人资料图片.用户有一个按钮.该按钮触发CamRoll功能.单击该按钮时,将ImagePickerViewController显示正常,但didFinishPickingMediaWithInfo不会调用该按钮.在早期版本的Swift/Xcode中,调用了相同的代码.这是我的代码.

import UIKit

class AnnonseViewController: UIViewController, UIImagePickerControllerDelegate {

@IBOutlet var Image: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.

}

@IBAction func CamRoll(_ sender: Any) {

    let imagePicker = UIImagePickerController()

    imagePicker.delegate = self

    imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary

    self.present(imagePicker, animated: true, completion: nil)

}

private func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [AnyHashable: Any]) {
    var image = info[UIImagePickerControllerOriginalImage] as! UIImage

    let imageSize = …

我在操场上.我试图使用arc4random_uniformfunc,但我收到此错误:使用未解析的标识符'arc4random_uniform'

我可以使用另一个func吗？
