Error LaunchServices: invalidationHandler called with social framework

I'm using Social Framework to share text on Facebook.

I've used this code:

NSArray *activityItems; NSString * prova=[NSString stringWithFormat:@"prova"];

 activityItems = @[self.ImageView.image,prova];

 UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];

 [self presentViewController:activityController animated:YES completion:nil];     

When I build in simulator it works well, but when I build in my iPhone I receive this error:

LaunchServices: invalidationHandler called
