Question

I am using ECsliding controller for slide menu.swipe gestrure working good in my case but when click button nothing happened.

My case is:

After two screen, I wanted to show slide menu so i have set ECSlide like belowe in my second screen and so far everything ok. In third view controller I set a button to show menu.Button get clicked but menu not open.

- (void)viewWillAppear:(BOOL)animated{
    if (![self.slidingViewController.underLeftViewController isKindOfClass:[LeftViewController class]]) {
        self.slidingViewController.underLeftViewController  = [self.storyboard instantiateViewControllerWithIdentifier:@"LeftViewController"];
    }

   [self.navigationController setNavigationBarHidden:YES animated:YES];
    if ([self.checkStr isEqualToString:@"1"])
    {
        //provider
        UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main"
                                                                 bundle: nil];

        LeftViewController *leftMenu = (LeftViewController*)[mainStoryboard
                                                             instantiateViewControllerWithIdentifier: @"LeftViewController"];
        // Create your menu view controller
        ProfileController *leftMenuONE = (ProfileController*)[mainStoryboard
                                                                      instantiateViewControllerWithIdentifier: @"ProfileControllerID"];






        // configure top view controller
        UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:leftMenuONE];

        self.slidingViewController = [ECSlidingViewController slidingWithTopViewController:navigationController];
        self.slidingViewController.underLeftViewController  = leftMenu;

        // enable swiping on the top view
        [navigationController.view addGestureRecognizer:self.slidingViewController.panGesture];

        // configure anchored layout
        self.slidingViewController.anchorLeftRevealAmount = 250.0;
        [self.navigationController pushViewController:self.slidingViewController animated:YES];

    }
    else
    {
        //user
        UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main"
                                                                 bundle: nil];

        LeftViewController *leftMenu = (LeftViewController*)[mainStoryboard
                                                             instantiateViewControllerWithIdentifier: @"LeftViewController"];
        // Create your menu view controller
        UserProfileController *leftMenuONE = (UserProfileController*)[mainStoryboard
                                                                      instantiateViewControllerWithIdentifier: @"UserProfileControllerID"];






        // configure top view controller
        UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:leftMenuONE];

        self.slidingViewController = [ECSlidingViewController slidingWithTopViewController:navigationController];
        self.slidingViewController.underLeftViewController  = leftMenu;

        // enable swiping on the top view
        [navigationController.view addGestureRecognizer:self.slidingViewController.panGesture];

        // configure anchored layout
        self.slidingViewController.anchorLeftRevealAmount = 250.0;
        [self.navigationController pushViewController:self.slidingViewController animated:YES];

    }
}

LeftViewController is my menu view controller.

Third view controller will load based condition.example if string is one,it will go to one view controller otherwise anther view controller.

Thirdview.h

- (IBAction)menuAction:(id)sender
{


        [self.slidingViewController anchorTopViewToRightAnimated:YES];

}
-(void)viewWillAppear:(BOOL)animated
{
    if (![self.slidingViewController.underLeftViewController isKindOfClass:[LeftViewController class]]) {
        self.slidingViewController.underLeftViewController  = [self.storyboard instantiateViewControllerWithIdentifier:@"LeftViewController"];
    }
}
