xamarin ios截图和电子邮件

如何截取屏幕截图并发送到带有按钮的电子邮件？ 我已经完成了截屏的编码，但它会保存到相册中。

partial void btnScreenshot (NSObject sender) { UIImage image; UIGraphics.BeginImageContext (View.Frame.Size); //new iOS 7 method to snapshot View.DrawViewHierarchy (View.Frame, true); image = UIGraphics.GetImageFromCurrentImageContext (); UIGraphics.EndImageContext (); //...code to save to photo album omitted for brevity image.SaveToPhotosAlbum((img, err) => { if(err != null) Console.WriteLine("error saving image: {0}", err); else Console.WriteLine ("image saved to photo album"); UIAlertView alert = new UIAlertView("Screenshot", "Image saved successfully", alertDelegate, "OK", null); alert.Show(); alert.Show(); }); }

您可以使用此Xamarin教程获取有关撰写电子邮件的说明。

然后要添加屏幕截图，您需要使用AddAttachmentData方法。

 // Take the screenshot UIGraphics.BeginImageContext(View.Frame.Size); View.DrawViewHierarchy(View.Frame, true); UIImage image = UIGraphics.GetImageFromCurrentImageContext(); UIGraphics.EndImageContext(); // Don't save it to the album (unless you need to) // Create an email var _mailController = new MFMailComposeViewController(); _mailController.SetToRecipients(new []{"[e-mail]"}); _mailController.SetSubject("Send Screenshot"); _mailController.SetMessageBody("This is a screenshot of the app!", false); // Add the screenshot as an attachment _mailController.AddAttachmentData(image.AsPNG(),"image/png","Screenshot.png"); // Handle the action to take when the user completes sending the email _mailController.Finished += ( object s, MFComposeResultEventArgs args) => { System.Console.WriteLine (args.Result.ToString ()); args.Controller.DismissViewController (true, null); }; // Show the email view PresentViewController (_mailController, true, null);
