SWRevealViewController - 防止与后视图交互

Question

当使用 SWRevealViewController 时，我不想让用户与打开侧边菜单的视图交互。侧边菜单打开后，我希望能够与该菜单视图进行交互，而不是另一个。

有什么帮助吗？

好吧，我已经在 SWRevealViewController 上工作了一段时间了 所以你需要将你的frontViewController添加为SWRevealViewControllerDelegate，然后实现这个功能

func revealController(revealController: SWRevealViewController!, willMoveToPosition position: FrontViewPosition)

frontViewController 向左或向前移动时会通知您

这是 Swift 代码

在你的frontViewController中你需要添加

class FrontViewController: UIViewController, SWRevealViewControllerDelegate
 {
override func viewDidLoad() {
super.viewDidLoad()
self.revealViewController().delegate = self;
 }

//您的代码//

func revealController(revealController: SWRevealViewController!, willMoveToPosition position: FrontViewPosition) {
        if(position == FrontViewPosition.Left)
        {
            self.view.userInteractionEnabled = true;
            self.navigationController?.navigationBar.userInteractionEnabled = true;
        }else
        {
            self.view.userInteractionEnabled = false;
            self.navigationController?.navigationBar.userInteractionEnabled = false;

        }
}

//已编辑

这是 Objective C 代码

class FrontViewController: UIViewController <SWRevealViewControllerDelegate>

在viewDidLoad中需要添加

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.revealViewController.delegate = self;
}

//您的代码//

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

希望对你有帮助
