<p>I'm using <code>MFSideMenu</code> which instantiated in <code>AppDelegate</code>, if I call </p>

<pre><code> `CMainViewController *vMain = [[UIStoryboard storyboardWithName:@"Main" bundle:NULL] instantiateViewControllerWithIdentifier:@"CMainView"];
[navigationController pushViewController:vMain animated:YES];` 
</code></pre>

<p>It works fine, if I not do a call (automatically view created) and inside this view do a call - I have the issue.</p>

<p>Any ideas - thanks in advance!</p>

<p>Find the place:
If I call pushViewController inside UIAlertView - I get the issue, if outside it works.</p>

<p>[[WashappService sharedInstance] auth:^(BOOL value) {
            if(value==TRUE){
                [self presentViewController:[LoginController authConfirmScreen:self toUser:user toPhone:szPhone  success:^{</p>

<pre><code>                [(MenuClientController*)self.menuContainerViewController.leftMenuViewController updateData];

                User* user = [User new];
                user = [UserPreference get:KEY_CLIENT];
                user.typeOwner = self.isWashAdmin;
                [UserPreference save:KEY_CLIENT toValue:user];
                [[WashappService sharedInstance] updateToken:user.token];

                if (self.isWashAdmin){
                    OOrdersViewController *vMain = [[UIStoryboard storyboardWithName:@"Main" bundle:NULL] instantiateViewControllerWithIdentifier:@"OOrdersViewController"];
                    [self.navigationController pushViewController:vMain animated:YES];
                }else{
                    CMainViewController *vMain = [[UIStoryboard storyboardWithName:@"Main" bundle:NULL] instantiateViewControllerWithIdentifier:@"CMainView"];
</code></pre>

<p>//                        vMain.modalPresentationStyle = UIModalPresentationFullScreen;
                        [self.navigationController pushViewController:vMain animated:YES];
