Hey !

I am trying to integrate social sharing functionality in my app through Objective C.

Could someone validate the methology - in particular the Objective C code ?

I would like to get an event in B4i when the user has completed sharing.

UPDATED: 09-05-2015: THIS VERSION DOES NOT WORK - PLEASE SEE POST #101 FOR A WORKING VERSION:
https://www.b4x.com/android/forum/t...elp-with-inline-objc.52849/page-6#post-336177

A BIG THANK YOU TO ALL WHO HELPED ME WITH THIS CODE !

Here is my code:

B4X: 
'Code module

Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'Public variables can be accessed from all modules.

End Sub


#If OBJC

- (IBAction)shareToSocialMedia:(NSString *)txt (NSString *)url: (NSString *)image
{
   //NSString *text = @"How to add Facebook and Twitter sharing to an iOS app";
   NSString *text = txt;
   //NSURL *url = [NSURL URLWithString:@"http://roadfiresoftware.com/2014/02/how-to-add-facebook-and-twitter-sharing-to-an-ios-app/"];
   NSURL *url = [NSURL URLWithString:url];
   //UIImage *image = [UIImage imageNamed:@"roadfire-icon-square-200"];
   UIImage *image = [UIImage imageNamed:image];

   UIActivityViewController *controller =
   [[UIActivityViewController alloc]
   initWithActivityItems:@[text, url, image]
   applicationActivities:nil];

  controller.excludedActivityTypes = @[UIActivityTypePostToWeibo,
  UIActivityTypeMessage,
  UIActivityTypeMail,
  UIActivityTypePrint,
  UIActivityTypeCopyToPasteboard,
  UIActivityTypeAssignToContact,
  UIActivityTypeSaveToCameraRoll,
  UIActivityTypeAddToReadingList,
  UIActivityTypePostToFlickr,
  UIActivityTypePostToVimeo,
  UIActivityTypePostToTencentWeibo,
  UIActivityTypeAirDrop];

   [self presentViewController:controller animated:YES completion:^{
     [self sharedone];
   }];
}

- (void)sharedone:
{
   int status = 1;
   [B4IObjectWrapper raiseEvent:self :@"onsharingdone:" :@[@((int)status)]];
   //[B4IObjectWrapper raiseEventFromDifferentThread:self :@"onsharingdone:" :@[@((int)status)]];

}

#end if

Sub onSharingDone(Status As Int)
   Log("onSharingDone: Status = " & Status)
End Sub

Sub ShareToSocialMedia(txt As String, theURL As String, imageFile As String)

   Dim NativeMe As NativeObject = Me
   NativeMe.RunMethod("shareToSocialMedia:", Array As Object(txt, theURL, imageFile))

End Sub

This line:
B4X: 
  extra += navBarHeight

should have been:

B4X: 
  extra += navBarHeight;

Please try once more ?

Could someone please try this code on IPAD ? I don't have access to an IPAD...

ok, but I would just prefer not to hardcode that value of 44 for the navBarHeight, but thanks for the feedback...
