本文介绍如何在iOS应用中集成相机与相册功能，包括必要的准备工作、代码实现细节及相册多选功能的实现。文章通过示例代码展示了如何创建UIImagePickerController实例，并设置其代理方法来处理用户选择的照片。

1.准备工作

在info.list
Privacy - Camera Usage Description//访问相机
Privacy - Photo Library Usage Description//访问相册
Localized resources can be mixed 设为YES //显示系统文字（要不然为英文）

2.代码


//遵守两个协议
class DataViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate{

 ///相机，相册
var cameraPicker: UIImagePickerController!
var photoPicker: UIImagePickerController!

  override func viewDidLoad() {
        super.viewDidLoad()
        self.initPhotoPicker()
        self.initCameraPicker()
    }
 //MARK: - Method
    func initCameraPicker(){
        cameraPicker = UIImagePickerController()
        cameraPicker.delegate = self
        cameraPicker.sourceType = .camera
        //在需要的地方present出来
        //self.present(cameraPicker, animated: true, completion: nil)
    }

    func initPhotoPicker(){
        photoPicker =  UIImagePickerController()
        photoPicker.delegate = self
        photoPicker.sourceType = .photoLibrary
        //在需要的地方present出来
        //self.present(photoPicker, animated: true, completion: nil)
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        self.dismiss(animated: true, completion: nil)
        //获得照片
        let image = info[UIImagePickerControllerOriginalImage] as! UIImage
        if photoArray.count < 6 {
           photoArray.insert(image, at: 0)
        }else {
            //最多上传6张
        }
     }
}
