xamarin ios 스크린 샷 및 이메일

Question

스크린 샷을 찍고 버튼을 사용하여 이메일로 보내는 방법은 무엇입니까? 나는 스크린 샷을 찍기위한 코드를 만들었지 만 사진 앨범에 저장됩니다.

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(); 
     }); 
    }

이메일을 작성하는 방법은 Xamarin tutorial을 사용할 수 있습니다.

그런 다음 스크린 샷을 추가하려면 AddAttachmentData 메서드를 사용해야합니다.

// 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 []{"john@doe.com"}); 
_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);
