界: Encapsulation

封装即绘制强边界。在 Web 浏览器中，这可能意味着确保您的移动代码不会被其他移动代码滥用。在服务器上，这可能意味着区分已验证数据和未验证数据、区分一个用户的数据和另一个用户的数据，或者区分允许用户查看的数据和不允许用户查看的数据。

Insecure Storage: Missing Encryption on Stored Private Media

Objective-C
Swift

Abstract

标识方法会将未加密数据写入 iOS 相册。

Explanation

保存到 iOS 相册中的文件可随意读取，并且可供设备中的应用程序访问。攻击者可以利用这一特点盗取敏感的照片，例如，用于手机支票存款的支票图片。

例 1：下面的代码使用 UIImageWriteToSavedPhotosAlbum 将图像保存到相册：


- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
	// Access the uncropped image from info dictionary
	UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];

  // Save image
  UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);

	...
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imageView.contentMode = .ScaleAspectFit
        imageView.image = pickedImage
    }

    // Save image
    UIImageWriteToSavedPhotosAlbum(pickedImage!, self, nil, nil)

    dismissViewControllerAnimated(true, completion: nil)
}
