推荐答案

您将需要一台服务器。这是一个漫长的过程。向您简要介绍详细信息

You will be needing a server for this. Its a long process. Briefing you with the overall details

• 您可以在用户登录时获得相关信息。


• 用户将尝试首先将图像发送到服务器。


• 从用户屏幕连续获取屏幕截图图像。点击此链接


• 转换图像到NSData 。


• 从服务器检测到另一个用户（要与谁共享屏幕）。将数据发送给该用户。并将NSData转换为UIImage并相应地更新UI。



• 循环流程。

• You get the information when users are loggedIn.
• User will try to send the image to the server first.
• Get the screenshots images continuously from the user screen.follow this link
• convert the image to NSData.
• From server detect the other user(to whom screen is to be shared.) send the data to that user. And convert the NSData into UIImage and update the UI accordingly.

• Loop the process.

// 用于拍摄屏幕截图

 UIGraphicsBeginImageContext(self.window.bounds.size);
    [self.window.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    NSData * data = UIImagePNGRepresentation(image);
    [data writeToFile:@"foo.png" atomically:YES];
