拍照、访问相册 swift

设置用户权限请求：

在Info.plist文件中添加Privacy - Camera Usage Description和Privacy - Photo Library Usage Description字段

设置代理：

class BasicPhotoViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate

 

代码实现：

1. 让用户选择从相册上传照片或是拍照

               let alert = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
               alert.addAction(UIAlertAction(title: "打开相机", style: .default, handler: { (alertCamera) in
                   let picker = UIImagePickerController()
                   picker.delegate = self
                   picker.sourceType = .camera
                   picker.allowsEditing = true
                   if UIImagePickerController.isSourceTypeAvailable(.camera) {
                       self.present(picker, animated: true, completion: nil)
                   } else {
                       self.showAwardInfo(info: "请打开相机权限")
                   }
               }))
               alert.addAction(UIAlertAction(title: "打开相册", style: .default, handler: { (alertAlbum) in
                   let picker = UIImagePickerController()
                   picker.delegate = self
                   picker.sourceType = .photoLibrary
                   picker.allowsEditing = true
                   if UIImagePickerController.isSourceTypeAvailable(.camera) {
                       self.present(picker, animated: true, completion: nil)
                   } else {
                       self.showAwardInfo(info: "请打开相册权限")
                   }
               }))
               alert.addAction(UIAlertAction(title: "取消", style: .cancel, handler: nil))
               self.present(alert, animated: true, completion: nil)

2. 实现代理方法

       func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
           if let choseImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
               picker.dismiss(animated: true) {
                   //自定义对图片choseImage处理
               }
           }
       }
