Question

I’m using ECSlidingViewController in my application, it contains owns GestureRecognizer that looks like:

[self.view addGestureRecognizer:self.slidingViewController.panGesture];

And it’s preventing TableView’s scrolling. When I deleted that line scroll works fine. What’s wrong with my approach?

Note: TableView is a part of Navigation Controller. And I’m using StoryBoards.

You need to add the UIGestureRecognizer to the view of the UINavigationController, not the the UITableView.

One way to do this is to create a UINavigationController subclass that handles the creation of both the gesture recognizer and the instantiation of your underLeft (or underRight) view controller for the ECSlidingViewController:

// MyNavigationController.h
@interface MyNavigationController : UINavigationController

@end

// MyNavigationController.m
@implementation MyNavigationController

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    if (![self.slidingViewController.underLeftViewController isKindOfClass:[MyLeftMenuViewController class]]) {
        self.slidingViewController.underLeftViewController  = [self.storyboard instantiateViewControllerWithIdentifier:@"MenuViewController"];
    }

    [self.view addGestureRecognizer:self.slidingViewController.panGesture];
}

@end

Open the Storyboard Editor, select the navigation controller and set the Identity Inspector’s Custom Class field to MyNavigationController (rather than the default UINavigationController).
