Here is a part of a code that I used in my apps and it works well in iOS 4.0 - iOS 6.0. Take a look:
-(void)sendMessageToEmail:(NSString *)message withSubject:(NSString *)subject
{
if([self _isIOS6andHigher]) {
NSArray *activities = #[message];
UIActivityViewController *viewController = [[UIActivityViewController alloc] initWithActivityItems:activities applicationActivities:nil];
AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
[[app navController] presentViewController:viewController animated:YES completion:nil];
[viewController release];
} else {
MFMailComposeViewController* mailController = [[MFMailComposeViewController alloc] init];
mailController.mailComposeDelegate = self;
[mailController setSubject:subject];
[mailController setMessageBody:message isHTML:NO];
AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
[[app navController] presentModalViewController:mailController animated:YES];
[mailController release];
}
}
- (void)mailComposeController:(MFMailComposeViewController*)controller
didFinishWithResult:(MFMailComposeResult)result
error:(NSError*)error
{
[controller dismissModalViewControllerAnimated:YES];
}

You never release mailComposer:
mailComposer = [[UIViewController alloc] init];
This might cause it to leak and remain active as a view. That could explain the lack of touch events because mail composer might still intercept touches.
