如何使用SWRevealViewController禁用邊欄菜單中的交互

Question

我遵循AppCoda.com的邊欄菜單教程，我遇到了問題。我想在用戶進入菜單時禁用用戶交互。目前，用戶仍然能夠與主屏幕進行交互，儘管它在菜單中。

Answer 1

將這個代碼在你TableViewController即菜單項控制器。本質上，這是視圖控制器，將坐在你的主視圖後面。

這也使得你的主視圖暗下去，如果你不希望出現這種情況，那麼alpha組件設置爲0。

let darkView = UIView() 

override func viewWillAppear(_ animated: Bool) { 

    darkView.addGestureRecognizer(revealViewController().tapGestureRecognizer()) 
    darkView.backgroundColor = UIColor.black.withAlphaComponent(0.7) 
    darkView.frame = self.revealViewController().frontViewController.view.bounds 
    self.revealViewController().frontViewController.view.addSubview(darkView) 
} 

override func viewWillDisappear(_ animated: Bool) { 
    darkView.removeFromSuperview() 
}

如果您正在使用SWRevealViewController的側欄。使用下面的代碼

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 
      } 
     ) 
    } 
} 

注意：別忘了在您的視圖控制器添加self.revealViewController().delegate = self，否則代表將不會被調用
