ios - SWRevealViewController 传递参数

Question

通过 SWRevealViewController 将参数从一个 ViewController 传递到另一个 ViewController。这不是在Front Controller和Rear Controller之间传递参数，而是从另一个ViewController(firstViewController)到前端(frontViewController.请参阅图片以供引用。 segue(在按钮触摸时)尝试将字符串值传递给前端 Controller

- (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:

1. 您必须将 SWRevealViewController 的 storyBoardId 命名为您想要的任何名称，在此示例中:“SWRevealViewController”

2. 遵循以下代码:

   let storyboard = UIStoryboard(name: "Main", bundle: nil)
   let revealVc = storyboard.instantiateViewController(withIdentifier :"SWRevealViewController") as! SWRevealViewController
   revealVc.loadView()
   let navViewController = revealVc.frontViewController as! UINavigationController
   if (navViewController.topViewController?.isKind(of: MainVc.superclass()!)) {
   let mainVc = navViewController.topViewController as! MainVc
   mainVc.email = email
   }
   self.present(revealVc, animated: true, completion: nil)
