Twitter Post iOS6 'Cancel' button issue - iphone

Question

I'm in the process of changing my app for iOS6 and iPhone use, I can't seem to figure out why when I post from Twitter using the new Social framework I have to press 'Cancel' twice to close, anybody else have this issue or a fix? Here is the code for the button.
- (IBAction)twitterPost:(id)sender
{
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{
mySLComposerSheet = [[SLComposeViewController alloc] init];
mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[mySLComposerSheet setInitialText:[NSString stringWithFormat:#"This is my tweet, hello!",mySLComposerSheet.serviceType]];
[self presentViewController:mySLComposerSheet animated:YES completion:nil];
}
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
NSLog(#"dfsdf");
switch (result) {
case SLComposeViewControllerResultCancelled:
break;
case SLComposeViewControllerResultDone:
break;
default:
break;
}
}];
}

Answer 1

If your using the mySLComposerSheet this works great...
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
[mySLComposerSheet dismissViewControllerAnimated:YES completion:nil];

Answer 2

My experience with SLComposeViewController is that twitter and weibo controllers need to be dismissed manually while the facebook controller seems to be better behaved.
If I don't dismissViewControllerAnimated myself, tapping the "Send" button will send the tweet or weibo posting but I'll be left with what seems to be an invisible view over my own view. Thus I can no longer interact with my app.
I don't know why my app is working like this... Interestingly, the completionHandler for cancel gets called just once. The second tap dismisses the view controller.
+ (void) shareText:(NSString*)text image:(UIImage*)image social:(NSString*)service url:(NSString*)url
{
SLComposeViewController* controller = [SLComposeViewController composeViewControllerForServiceType:service];
[controller setInitialText:text];
[controller addImage:image];
[controller addURL:[NSURL URLWithString:url]];
controller.completionHandler = ^(SLComposeViewControllerResult result) {
if( SLComposeViewControllerResultDone == result )
{
NSLog(#"rewards for share: %#!", service );
}
if( ![SLServiceTypeFacebook isEqualToString:service] ) // facebook behaves
[[CBLAppDelegate instance].activeViewController dismissViewControllerAnimated:true completion:nil];
};
[[CBLAppDelegate instance].activeViewController presentViewController:controller animated:true completion:nil];
}

Answer 3

Found the issue. It only happens when a completion handler is added to TWTweetComposeViewController. If added, make sure to call:
[self dismissModalViewControllerAnimated:YES];

Answer 4

Try this buddy
[mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
switch (result) {
case SLComposeViewControllerResultCancelled:
[self performSelector:#selector(showalert)];
[mySLComposerSheet dismissViewControllerAnimated:YES completion:nil];
break;
case SLComposeViewControllerResultDone:
[self performSelector:#selector(showalert1)];
[mySLComposerSheet dismissViewControllerAnimated:YES completion:nil];
break;
default:
break;
}
}];

Posting comment above as an answer:
Have you tried setting the completionHandler before presenting the View Controller?
