当点击前视图时，SWRevealViewController关闭后视图

Question

我正在使用SWRevealViewController来在我的应用中实现侧面导航菜单。我想这样做是为了在打开后视图时不能与前视图交互，除了当用户轻敲前视图时，后视图将关闭并且前视图可以再次交互。我有两个SWRevealViewController委托方法，目前正在从前视图中删除交互。

- (void)revealController:(SWRevealViewController *)revealController willMoveToPosition:    (FrontViewPosition)position {
    if(position == FrontViewPositionLeft) {
        self.view.userInteractionEnabled = YES;
    } else {
        self.view.userInteractionEnabled = NO;
    }
}

- (void)revealController:(SWRevealViewController *)revealController didMoveToPosition:    (FrontViewPosition)position {
    if(position == FrontViewPositionLeft) {
        self.view.userInteractionEnabled = YES;
    } else {
        self.view.userInteractionEnabled = NO;
    }
}

然而，当轻敲前视图时，这不会导致后视图关闭。非常感谢任何帮助，谢谢！

Answer 1

如果您使用的是SWIFT，您可以在frontViewController中执行以下操作：

override func viewDidLoad() {
    super.viewDidLoad()

    if self.revealViewController() != nil {

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

}

代码适用于TAP和PAN手势。

Answer 2

在frontViewController的ViewDidLoad中，您需要添加UITapGestureRecognizer

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

[myView addGestureRecognizer:tap];

这会导致后视图在点按前视图时关闭，这是SWRevealViewController的默认行为。

编辑：更改UIView的autoresizingMask以适应Swift 2，感谢Marroc的comment

这是@ avdyushin答案的Swift-SWRevealViewController 2.x版本：

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
            }
        )
    }
}

Answer 4

1. SWRevealViewController。
的子类
2. 实施revealController:willMoveToPosition:的{​​{1}}。
3. 在前视图控制器上设置全屏视图以覆盖所有触摸。
4. 添加点击手势识别器以隐藏菜单。

Answer 5

考虑这个简单的解决方案，效果很好

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()
        }
    }
}

UIViewController中的简单用法：

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

    setupMenuGestureRecognizer()
}

Answer 6

将以下代码放在菜单视图控制器上，它适用于我

@interface SidebarTableViewController() {
    UIView* coverView;
}

- (void)viewWillDisappear:(BOOL)animated {
    [coverView removeFromSuperview];
    //[self.revealViewController.frontViewController.view setUserInteractionEnabled:YES];
    // get your window screen size
}

- (void)viewWillAppear:(BOOL)animated {
    // get your window screen size
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    //create a new view with the same size
    coverView = [[UIView alloc] initWithFrame:screenRect];
    // change the background color to black and the opacity to 0.6
    coverView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.6];
    // add this new view to your main view
    [self.revealViewController.frontViewController.view addSubview:coverView];
    // [self.revealViewController.frontViewController.view setUserInteractionEnabled:NO];
}

感谢mixth＆amp; avdyushin因为那里有很大的帮助。这里是从那里得到的Swift 4版本的答案，以节省您的几个小时：

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
        }
        )
    }
}

}

  

现在从后视图控制器的 viewDidLoad 调用此功能 setupMenuGestureRecognizer 。

或者您也可以将 SWRevealViewControllerDelegate 直接实现到后视图控制器类，并在类本身中使用SWRevealViewControllerDelegate函数。

我使用了tapGestureRecognizer，但仍然存在一些问题。我试过这个并且效果很好！

定义课程：

@interface IgnoreView : UIView

@property (nonatomic, assign) BOOL shouldAllTouchesBeForMe;

@end

实施：

@implementation IgnoreView

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

@end

然后在IgnoreView类的Interface Builder中创建View类

在ViewController中，执行：

in - viewDidLoad

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

viewcontroller中的工具也是：

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

你们都准备好了！

Answer 9

在菜单视图控制器上，添加以下内容：

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

    [self.revealViewController.frontViewController.view setUserInteractionEnabled:NO];
}

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

    [self.revealViewController.frontViewController.view setUserInteractionEnabled:YES];
}

然后在菜单项视图控制器上，在 viewDidLoad 上添加：

SWRevealViewController *revealController = [self revealViewController];
[revealController tapGestureRecognizer];

另请查看我的回答here。它解决了前视图交互（加上幻灯片手势）的问题。
