Question

我试图在swift 3中成功登录时执行segue。一旦我的web服务返回成功消息，我想执行segue。我正在尝试以下方式：

DispatchQueue.main.sync(execute: {
       print("Login successful")
       self.performSegue(withIdentifier: "goToTimerPage", sender: self)
})

我的日志打印正常。请帮我解决一下这个。我是网络服务的新手。

Answer 1

简单的导航方式。

像这样设置didFinishLaunchingWithOptions。

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {


    let storyboard :UIStoryboard

    if  UIDevice.currentDevice().userInterfaceIdiom == .Pad{

        storyboard = UIStoryboard(name: "Main_iPad", bundle: nil)
    }
    else{
        storyboard = UIStoryboard(name: "Main", bundle: nil)
    }


    let navigationController:UINavigationController = storyboard.instantiateInitialViewController() as! UINavigationController

    let objLoginViewController:UIViewController = storyboard.instantiateViewControllerWithIdentifier("ID_LoginViewController") as! LoginViewController

    navigationController.viewControllers = [objLoginViewController]


    if self.window != nil {
        self.window!.rootViewController = navigationController
    }



    return true
}

获得成功回复后调用此函数。

self.redirectToNewViewcontroller()

redirectToNewViewcontroller函数的代码

func redirectToNewViewcontroller()
{
    let objNewViewController = self.storyboard?.instantiateViewControllerWithIdentifier("ID_NewViewController") as? NewViewController

    self.navigationController?.pushViewController(objNewViewController!, animated: true)
}

像这样使用

Answer 3

只需确保将视图控制器嵌入导航控制器即可源视图控制器不是目标视图控制器

完成Web服务调用Swift3后执行segue
