Question

我使用SWReveal视图控制器创建了侧面菜单结构。我想要做的是取消在某些页面上打开右侧视图控制器。我已经研究并发现了类似这样的内容：

- (BOOL)revealControllerPanGestureShouldBegin:(SWRevealViewController *)revealController

  if([revealController.frontViewController isKindOfClass:[UINavigationController class]]){

    UINavigationController *navController = (UINavigationController *)revealController.frontViewController;

    UIViewController *lastViewController = navController.viewControllers.lastObject;

    if([lastViewController isKindOfClass:[DetailViewController class]] ||
       [lastViewController isKindOfClass:[TableDateViewController class]] ||
       [lastViewController isKindOfClass:[MapViewController class]])
    {
        return NO; // I do not want to open it for the view controllers I want
    }
 }
   return YES;   
 }

这对我有用，但它也影响了左页的打开。触摸动作（点击手势）没有问题，但这适用于平移手势。我的意思是平移手势不适用于视图控制器我想运行。我想为某些视图控制器正常工作，但我不想影响左侧。我添加了这样的权利切换：

-(void)sideRightMenuLoad{
[((PersonelViewController *)[self.navigationController.viewControllers objectAtIndex:0]).view addGestureRecognizer:self.revealViewController.panGestureRecognizer];

SWRevealViewController *revealViewController = self.revealViewController;
if(revealViewController){
    [self.sideRightBarButton setTarget:self.revealViewController];
    [self.sideRightBarButton setAction:@selector(rightRevealToggle:)];
    [self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];


}

此代码需要打开右侧页面：

[self performSegueWithIdentifier:SWSegueRightIdentifier sender:nil];

我试图在我想要的时候运行它，但它没有用。我正在等待这方面的帮助。谢谢。

你必须检查平移手势的方向：

- (BOOL)revealControllerPanGestureShouldBegin:(SWRevealViewController *)revealController {
if ([revealController.panGestureRecognizer velocityInView:revealController.view].x < 0) {
    // pan direction left, should open right side
    // ...
    return NO;
}
return YES;

}

func revealControllerPanGestureShouldBegin(_ revealController: SWRevealViewController!) -> Bool {
    let point = revealController.panGestureRecognizer().location(in: self.view)

    if revealController.frontViewPosition == FrontViewPosition.left && point.x < 50.0 {
        print("YES YES YES YES RRRRIIIIGGGGHHHHTTTT")
        return false

    }
    else if revealController.frontViewPosition == FrontViewPosition.right {
        print("YES YES YES YES LLLLEEEEFFFFTTTT")
        return true
    }

    return false
}
