var photoButton : UIButton!
var image : UIImageView!
override init(frame : CGRect)
{

控制类 ViewController.swift 代码内容:
import UIKit
import AVFoundation
import AssetsLibrary
import Photos
class ViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate {
var cameraView = CameraView()
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor.white

self.view.addSubview(cameraView)
cameraView.cameraButton.addTarget(self, action: #selector(ViewController.cameraEvent), for: .touchUpInside)
cameraView.photoButton.addTarget(self, action: #selector(ViewController.photoEvent), for: .touchUpInside)
// Do any additional setup after loading the view, typically from a nib.
}
var picker: UIImagePickerController?
//相册
@objc func cameraEvent(){
let pickerCamera = UIImagePickerController()
pickerCamera.allowsEditing = true

self.present(pickerCamera, animated: true, completion: nil)
}
//相机
@objc func photoEvent(){

}
let pickerPhoto = UIImagePickerController()
pickerPhoto.delegate = self
pickerPhoto.allowsEditing = true//设置可编辑
pickerPhoto.sourceType = sourceType
self.present(pickerPhoto, animated: true, completion: nil)//进入照相界面
}
//MARK: - UIImagePickerControllerDelegate、UINavigationControllerDelegate
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
//UIImagePickerControllerOriginalImage 原始图像
//UIImagePickerControllerEditedImage 编辑后的图片(开启编辑该对象才存在)
var imagePickerc = info[UIImagePickerController.InfoKey.originalImage] as? UIImage

}
cameraView.image.image = imagePickerc
self.dismiss(animated: true, completion: nil)
}
override func didReceiveMemoryWarning() {
