SWRevealViewController传递参数

Question

通过SWRevealViewController将参数从一个ViewController传递到另一个ViewController。这不是关于在前端控制器和后端控制器之间传递参数，而是从另一个ViewController (firstViewController)传递到前端(frontViewController。参考图片。segue (在触摸按钮时)尝试将字符串值传递给前端控制器

图片在这里：http://portwire.com/stackoverflow/storyboard.png

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    SWRevealViewController *destinationViewController = (SWRevealViewController *)segue.destinationViewController;
    UINavigationController *navegationController = (UINavigationController *)destinationViewController.frontViewController;

    //UUPS!! SWRevealViewController.frontViewController is nil

    //How to access destination UIViewController????????

    FrontViewController * frontViewController = (FrontViewController *)navegationController.topViewController;
    frontViewController.fromString = @"String from previous view";
}

Answer 1

对于Swift 3.0：

• 你必须为storyBoardId SWRevealViewController命名为你想要的任何东西，在这个例子中："SWRevealViewController“

1. 遵循下面的代码: let storyboard = UIStoryboard(name："Main"，bundle: nil)让revealVc =Main :"SWRevealViewController") as！SWRevealViewController revealVc.loadView()让navViewController = revealVc.frontViewController as！UINavigationController if (navViewController.topViewController?.isKind(of: MainVc.superclass()!)) {让mainVc = navViewController.topViewController as！MainVc mainVc.email =电子邮件} self.present(revealVc，动画:真，完成:无)

我有第一个LoginViewController -> SWRevealViewController -> NavigationController -> HomeViewController (HomeViewController是frontViewController)

从LoginViewController到SWRevealViewController，我有一个段。为了传递数据，我在prepareForSegue中使用了适合我的代码。

if ([[segue identifier] isEqualToString:@"homeVC"]) {

   SWRevealViewController *destination = [segue destinationViewController];
   [destination loadView];
   UINavigationController *navViewController = (UINavigationController *) [destination frontViewController];

   if ([navViewController.topViewController isKindOfClass:[HomeViewController class]]) {

        HomeViewController* homeVC = (HomeViewController*)navViewController.topViewController;
        homeVC.title = @"Test1";
                } }

希望能对你有所帮助！

我认为你可以使用委托来做这件事。

在您的前视图控制器中定义一个协议，并让第一个视图控制器符合它。
