SWRevealViewController:显示后视镜时删除前视图上的交互

我最近提出了一个解决方案,我想与大家分享 (如果晚了两个月,很抱歉)。

为了在菜单打开时禁用前视图上的用户交互,我在 菜单视图控制器 :

在…上 视图将出现 :

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

和 视图将消失 :

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

这将禁用前视图控制器上的所有用户交互,这意味着关闭菜单的滑动/轻击手势也将被禁用。

现在,我已经创建了一个 父视图控制器 并使所有视图控制器(菜单项)成为其子类。

在我的 视图DidLoad ,我输入了以下代码:

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

如果此时运行应用程序,则“轻触手势”似乎有效(点击“前视图”将关闭“菜单”),但“平移手势”无效。我不知道为什么会这样,但为了使滑动手势关闭菜单,请在 菜单视图控制器 :

在…上 视图将出现 :

[self.revealViewController.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

总而言之,以下是您需要的:

在您的 菜单视图控制器 :

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

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

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

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

在菜单项的视图控制器上(您可以 父视图控制器 对于所有这些):

-(void)viewDidLoad {
    [super viewDidLoad];

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

希望这有帮助!

我使用了另一种方法来实现同样的结果,但不确定这是否有帮助。

分配 SWRevealViewControllerDelegate 到 应用程序委托

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    SWRevealViewController* reveal = (SWRevealViewController*)self.window.rootViewController;
    reveal.delegate = self;

    // other bootstrapping code
}

然后在 代表 方法 -(void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position 如下所示:

-(void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position
{
    if(position == FrontViewPositionLeft){
        [revealController.frontViewController.view setUserInteractionEnabled:YES];
        [revealController.frontViewController.revealViewController tapGestureRecognizer];
    }else{
        [revealController.frontViewController.view setUserInteractionEnabled:NO];
    }
}

已更新 :添加了此行 [revealController.frontViewController.revealViewController tapGestureRecognizer] 点击frontviewcontroller时关闭显示的控制器

@hardluckbaby的Swift版本回答:

在里面 菜单视图控制器 ( 后视控制器 ):

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

    self.revealViewController().frontViewController.view.userInteractionEnabled = false
    self.revealViewController().view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}

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

    self.revealViewController().frontViewController.view.userInteractionEnabled = true
}

在里面 FrontView控制器 (你可以 父视图控制器 对于@hardluckbaby所说的所有前视图控制器):

override func viewDidLoad() {
    super.viewDidLoad()

    if let revealController = self.revealViewController() {
        revealController.panGestureRecognizer()
        revealController.tapGestureRecognizer()
    }
}

正如John所解释的:虽然这些解决方案确实有效,但我认为它们都没有解决最初的问题,这实际上很简单:

涉及两个步骤:

1. 将以下方法添加到FrontViewController.m中:

   • (void)revalController:(SWRevealViewController*)revalController willMoveToPosition:(FrontViewPosition)位置{ if(位置==FrontViewPositionLeft){ self.view.userInteractionEnabled=是; }其他{ self.view.userInteractionEnabled=否; } }

   • (void)revalController:(SWRevealViewController*)revalController didMoveToPosition:(FrontViewPosition)位置{ if(位置==FrontViewPositionLeft){ self.view.userInteractionEnabled=是; }其他{ self.view.userInteractionEnabled=否; } }

2. 使前视图控制器成为FrontViewController.h文件中SWRevealViewController的代理:

(例如@interface HomeViewController:UIViewController) 其中我的FrontViewController被命名为HomeViewController

以及FrontViewController.m文件中的ViewDidLoad上的以下内容:

self.revelViewController.default=self; 问题解决了!比创建父类等容易得多。

这将帮助您解决FrontView控制器的用户交互问题。我只需添加上面从Xun的响应中得到的以下更改,当用户点击FrontViewController时,您将解决用户交互和隐藏菜单。

- (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;
      //Hides the menu when user taps FrontViewController
       [revealController.frontViewController.revealViewController tapGestureRecognizer];
    } 
}

斯威夫特3.0 方法简单快速。

此处为Frontviewcontroller代码。。。

override func viewDidLoad() {
    super.viewDidLoad()
     if self.revealViewController() != nil {
        let rewel:SWRevealViewController  = revealViewController()
        rewel.panGestureRecognizer()
        rewel.tapGestureRecognizer() 
    }
}

SideDrowerview控制器代码。。。

override func viewWillAppear(_ animated: Bool) {
  let rewel = self.revealViewController()
      rewel?.frontViewController.view.isUserInteractionEnabled = false
    rewel?.frontViewController.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}

override func viewWillDisappear(_ animated: Bool) {
    let rewel = self.revealViewController()
        rewel?.frontViewController.view.isUserInteractionEnabled = true
}

打开后视图时,将子视图添加到前视图。

在菜单项控制器的viewWillAppear方法中,只需在前视图上创建一个覆盖按钮,并将操作设置为revalToggle:of revalViewController

-(void)viewWillAppear:(BOOL)animated 
{
    [super viewWillAppear:animated];
    overlayView = [UIButton buttonWithType:UIButtonTypeCustom];
    overlayView.frame = self.revealViewController.frontViewController.view.bounds;
    overlayView.backgroundColor = [UIColor colorWithWhite:0.5 alpha:0.8];
    overlayView.tag = 999;
    [overlayView addTarget:self.revealViewController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchUpInside];
    [overlayView addTarget:self.revealViewController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchDragOutside];
    [self.revealViewController.frontViewController.view addSubview:overlayView];
}

在revalToggle方法中,删除覆盖按钮(如果有):

- (void)revealToggleAnimated:(BOOL)animated
{
    UIButton *overlayView = (UIButton*)[self.view viewWithTag:999];
    if (overlayView) {
        [overlayView removeFromSuperview];
        overlayView = nil;
    }
    // rest of the code...
}

尽管这些解决方案确实有效,但我认为它们都没有解决最初的问题,这实际上很简单:

涉及两个步骤:

1) 将以下方法添加到 FrontViewController.m :

- (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;
    } 
}

2) 使您的前视图控制器成为SWRevealViewController的代理 FrontViewController.h 文件:

(e.g. @interface HomeViewController : UIViewController <SWRevealViewControllerDelegate>)

其中我的FrontViewController被命名为HomeViewController

以及 FrontViewController.m ViewDidLoad上包含以下内容的文件:

self.revealViewController.delegate = self;

问题解决了!比创建父类等容易得多。

另一种方法是在显示后视图时使用覆盖视图。您可以使用此更新的库 https://github.com/NSRover/SWRevealViewController 并确保在显示后视图时包含shouldUseFrontViewOverlay=true。

class SideMenuViewController: UITableViewController {

  override func viewDidLoad() {
    super.viewDidLoad()
    self.revealViewController().delegate = self
  }

}

extension SideMenuViewController: SWRevealViewControllerDelegate {

  func revealController(revealController: SWRevealViewController!, willMoveToPosition position: FrontViewPosition) {
    if position == .Left {
      revealController.frontViewController.view.userInteractionEnabled = true
    }

    if position == .Right {
      revealController.frontViewController.view.userInteractionEnabled = false
    }
  }

}

On MenuTableViewController/ Rear VC, add SWRevealViewControllerDelegate.

    override func viewDidLoad() {
        super.viewDidLoad()
        self.revealViewController().delegate = self

        if self.revealViewController() != nil {
            self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
        }
    }

Add this delegate method.

func revealController(revealController: SWRevealViewController!, didMoveToPosition position: FrontViewPosition) {
        if(position.rawValue == 4)
        {
            //move to rear
            self.revealViewController().frontViewController.view.userInteractionEnabled =  false
        }
        else if (position.rawValue == 3)
        {
            //move to front - dashboard VC
            self.revealViewController().frontViewController.view.userInteractionEnabled =  true
        }
    }
    func revealController(revealController: SWRevealViewController!, willMoveToPosition position: FrontViewPosition) {

//will perform the same function as the above delegate method.
    }

考虑以下解决方案,效果完美

private let DimmingViewTag = 10001

extension UIViewController: SWRevealViewControllerDelegate {    

    func removeInteractionFromFrontViewController() {

        revealViewController().delegate = self

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

    //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()
        }
    }
}

中的简单用法 UIViewController :

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

    removeInteractionFromFrontViewController()
}

如果此时运行应用程序,则点击 手势有效(点击前视图将关闭菜单),但不 潘手势。我不知道为什么会这样,但为了 使用滑动手势关闭菜单,在菜单中添加以下代码 菜单视图控制器:

在视图中将出现:

[self.revealViewController.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

它增加了一些不期望的行为,例如,当启动时,平移手势将关闭后视图。

如果您将默认平移手势添加到您自己的视图中,例如在 视图DidLoad 前视图控制器:

[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

删除这些线条,这应该可以像预期的那样,用于平移和轻敲手势

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

我使用的是viewWillAppear和viewWillDisappear功能,但因为我在侧菜单中几乎每个项目都有子视图。我的问题是我有一个激活的输入字段(键盘显示)并访问了侧菜单。在根菜单中,键盘隐藏,但在我进入子菜单后,键盘再次出现。为了解决这个问题,我改变了在revalController中启用和禁用交互的方法,如下所示:

- (void)revealController:(SWRevealViewController *)revealController 
        didMoveToPosition:(FrontViewPosition)position {
    if (position == FrontViewPositionRight) {
        [self.revealViewController.frontViewController.view setUserInteractionEnabled:NO];
    } else if (position == FrontViewPositionLeft) {
        [self.revealViewController.frontViewController.view setUserInteractionEnabled:YES];
    }
}

首先,只需设置您的代理人: self.revelViewController.default=self; 委托方法如下:

- (void)revealController:(SWRevealViewController *)revealController willMoveToPosition:(FrontViewPosition)position
{
    static NSInteger tagLockView = 123456789;
    if (revealController.frontViewPosition == FrontViewPositionRight)
    {
        UIView *lockView = [self.view viewWithTag:tagLockView];

        [UIView animateWithDuration:0.3 animations:^{
            lockView.alpha = 0;
        } completion:^(BOOL finished) {
            [lockView removeFromSuperview];
        }];
    }
    else if (revealController.frontViewPosition == FrontViewPositionLeft)
    {
        UIView *lockView = [[UIView alloc] initWithFrame:self.view.bounds];
        lockView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        lockView.tag = tagLockView;
        lockView.backgroundColor = [UIColor blackColor];
        lockView.alpha = 0;
        [lockView addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self.revealViewController action:@selector(revealToggle:)]];
        [self.view addSubview:lockView];
        [UIView animateWithDuration:0.3 animations:^{
            lockView.alpha = 0.5;
        }];
    }

}
