How to enable two view controllers in the same window

Question

I'm trying to develop a slide menu in my application which should open the menu view from the left (or the right) depending on the swipe direction.

What I did till now:

1- Create a main View Controller A

2- Create left (or right) View Controller B

3- When Slide button tapped, add B ViewController as a sub View for the A View Controller.

4- here's my code:

CGRect currentLeftFrame  = self.leftVC.view.frame;
    currentLeftFrame.origin  = CGPointMake(-1.0f * self.view.frame.size.width, 0.0f);
    self.leftVC.view.frame   = currentLeftFrame;
    [self addChildViewController:self.leftVC];
    [self.view addSubview:self.leftVC.view];
    [self.leftVC didMoveToParentViewController:self];

The problem is that buttons in the B View controller are not clickable.

Do one know how to solve this problem?

Thanks in advance.

将UIView用于幻灯片面板，并将幻灯片视图添加为viewController的视图或应用程序窗口上的子视图。
