SWRevealViewController close rear view when tapping front view

Question

I am using SWRevealViewController in order to implement a side nav menu in my app. I would like to make it so that the front view cannot be interacted with when

Answer 1

I used the tapGestureRecognizer but there are still some problems. I tried this and worked great!

Define class:

@interface IgnoreView : UIView

@property (nonatomic, assign) BOOL shouldAllTouchesBeForMe;

@end

Implement:

@implementation IgnoreView

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
    if( self.shouldAllTouchesBeForMe ){
        return self;
    }
    return [super hitTest:point withEvent:event];
}

@end

Then make your View class in Interface Builder of class IgnoreView

In your ViewController, then, do:

in - viewDidLoad

self.revealViewController.delegate = self;
[self.view addGestureRecognizer:self.revealViewController.tapGestureRecognizer];

the implement in your viewcontroller also:

- (void)revealController:(SWRevealViewController *)revealController didMoveToPosition:(FrontViewPosition)position
{
    IgnoreView *i = (id)self.view;
    i.shouldAllTouchesBeForMe = position == FrontViewPositionRight;
}

And you're all set!

Answer 2

In ViewDidLoad of your frontViewController you need to add a UITapGestureRecognizer

SWRevealViewController *revealController = [self revealViewController];
UITapGestureRecognizer *tap = [revealController tapGestureRecognizer];
tap.delegate = self;

[myView addGestureRecognizer:tap];

This should cause the rear view to close when the front view is tapped which is SWRevealViewController's default behaviour.

Consider this simple solution, works perfect

private let DimmingViewTag = 10001

extension UIViewController: SWRevealViewControllerDelegate {    

    func setupMenuGestureRecognizer() {

        revealViewController().delegate = self

        view.addGestureRecognizer(revealViewController().panGestureRecognizer())
        view.addGestureRecognizer(revealViewController().tapGestureRecognizer())
    }

    //MARK: - SWRevealViewControllerDelegate

    public func revealController(revealController: SWRevealViewController!, didMoveToPosition position: FrontViewPosition) {

        if case .Right = position {

            let dimmingView = UIView(frame: view.frame)
            dimmingView.tag = DimmingViewTag

            view.addSubview(dimmingView)
            view.bringSubviewToFront(dimmingView)

        } else {
            view.viewWithTag(DimmingViewTag)?.removeFromSuperview()
        }
    }
}

Simple usage in UIViewController:

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    setupMenuGestureRecognizer()
}

EDIT: Change UIView's autoresizingMask to suit Swift 2, thanks to Marroc's comment

This is Swift-SWRevealViewController 2.x version of @avdyushin's answer:

func revealController(revealController: SWRevealViewController!, willMoveToPosition position: FrontViewPosition) {
    let tagId = 4207868622

    if revealController.frontViewPosition == FrontViewPosition.Right {
        let lock = self.view.viewWithTag(tagId)
        UIView.animateWithDuration(0.25, animations: {
                lock?.alpha = 0
            }, completion: {(finished: Bool) in
                lock?.removeFromSuperview()
            }
        )
        lock?.removeFromSuperview()
    } else if revealController.frontViewPosition == FrontViewPosition.Left {
        let lock = UIView(frame: self.view.bounds)
        lock.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
        lock.tag = tagId
        lock.alpha = 0
        lock.backgroundColor = UIColor.blackColor()
        lock.addGestureRecognizer(UITapGestureRecognizer(target: self.revealViewController(), action: "revealToggle:"))
        self.view.addSubview(lock)
        UIView.animateWithDuration(0.75, animations: {
                lock.alpha = 0.333
            }
        )
    }
}

If you are using SWIFT, you can do something like this, in your frontViewController:

override func viewDidLoad() {
    super.viewDidLoad()

    if self.revealViewController() != nil {

        self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
        self.view.addGestureRecognizer(self.revealViewController().tapGestureRecognizer())
    }

}

Code works for TAP and PAN gesture.

Thanks to mixth & avdyushin for there mighty help. Here's the Swift 4 version derived from there answer to save your couple of hours:

extension UIViewController: SWRevealViewControllerDelegate {

func setupMenuGestureRecognizer() {

    revealViewController().delegate = self

    view.addGestureRecognizer(revealViewController().panGestureRecognizer())
    view.addGestureRecognizer(revealViewController().tapGestureRecognizer())
}

//MARK: - SWRevealViewControllerDelegate
public func revealController(_ revealController: SWRevealViewController!, willMoveTo position: FrontViewPosition) {
    let tagId = 112151
    print("revealController delegate called")
    if revealController.frontViewPosition == FrontViewPosition.right {
        let lock = self.view.viewWithTag(tagId)
        UIView.animate(withDuration: 0.25, animations: {
            lock?.alpha = 0
        }, completion: {(finished: Bool) in
            lock?.removeFromSuperview()
        }
        )
        lock?.removeFromSuperview()
    } else if revealController.frontViewPosition == FrontViewPosition.left {
        let lock = UIView(frame: self.view.bounds)
        lock.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        lock.tag = tagId
        lock.alpha = 0
        lock.backgroundColor = UIColor.black
        lock.addGestureRecognizer(UITapGestureRecognizer(target: self.revealViewController(), action: #selector(SWRevealViewController.revealToggle(_:))))
        self.view.addSubview(lock)
        UIView.animate(withDuration: 0.75, animations: {
            lock.alpha = 0.333
        }
        )
    }
}

}

Now call this function setupMenuGestureRecognizer from viewDidLoad of your rear view controller.

Or you can also implement SWRevealViewControllerDelegate directly to your rear view controller class and use the SWRevealViewControllerDelegate function in the class itself.
