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
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.
