-(void) presentShareController:(SLComposeViewController*)shareCompose
{
    if ([shareCompose.serviceType isEqualToString:SLServiceTypeFacebook]) {
        
        UIWindow *window = [[UIApplication sharedApplication] keyWindow];
        UIWindowLevel prevWindowLevel = window.windowLevel;
        window.windowLevel = UIWindowLevelNormal;
        
        SLComposeViewControllerCompletionHandler handler = shareCompose.completionHandler;
        shareCompose.completionHandler = ^(SLComposeViewControllerResult result){
            window.windowLevel = prevWindowLevel;
            if (handler) {
                handler(result);
            }
        };
        
    }
    
    [self presentViewController:shareCompose
                        animated:YES
                      completion:nil];
