推荐答案

经过搜索，我发现在 iOS6 中使用 UIActivityViewController 的方法似乎很标准".

After searching, I found a way seems quite "standard" way in iOS6 by using UIActivityViewController.

以下是来自 developer.apple.com 的描述:

Following is the description from developer.apple.com:

UIActivityViewController 类是一个标准的视图控制器，您可以使用它从您的应用程序中提供各种服务.该系统提供多种标准服务，例如将项目复制到粘贴板、将内容发布到社交媒体网站、通过电子邮件或短信发送项目等.应用还可以定义自定义服务.

The UIActivityViewController class is a standard view controller that you can use to offer various services from your application. The system provides several standard services, such as copying items to the pasteboard, posting content to social media sites, sending items via email or SMS, and more. Apps can also define custom services.

以下是我使用 UIActivityViewController 设法生成的对话框

以下是我使用的源代码:

And following is the source code I use:

NSArray *activityItems = [NSArray arrayWithObjects: share_text.text, share_image.image , nil];

    UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
    [self presentViewController:activityController animated:YES completion:nil];
