我是編程新手,現在正在嘗試做一個應用程序。當我嘗試創建Google Sign登錄按鈕時,問題就開始了,當我以爲自己已經完成了這個任務時,我嘗試了模擬器,並且沒有任何按鈕在點擊時運行,甚至沒有任何按鈕可以工作。然後模擬器開始與代碼Thread 1:SIGABRT一起崩潰。我在某個地方讀過,你可以做一個豁免中斷點,看看問題出在哪裏,當我這樣做時,我來到了一些線上,其中一個線程表示線程1:斷點3.1。在模擬器上運行應用程序時,它崩潰並說線程1:斷點3.1。我該怎麼辦?

import UIKit 
import Google 

class ViewController: UIViewController, GIDSignInUIDelegate { 

    override func viewDidLoad() { 
    super.viewDidLoad() 

    GIDSignIn.sharedInstance().uiDelegate = self 


    // Do any additional setup after loading the view, typically from a nib. 

} 


override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 

    // Dispose of any resources that can be recreated. 
} 
@IBOutlet weak var signinbutton3: GIDSignInButton! 

@IBOutlet weak var signinbutton: GIDSignInButton! 

func signInWillDispatch(signIn: GIDSignIn!, error: NSError!) { 

} 

// Present a view that prompts the user to sign in with Google 
func signIn(signIn: GIDSignIn!, 
      presentViewController viewController: UIViewController!) { 
    self.present(viewController, animated: true, completion: nil) 

    print("Sign in presented") 
} 

// Dismiss the "Sign in with Google" view 
func signIn(signIn: GIDSignIn!, 
      dismissViewController viewController: UIViewController!) { 
    self.dismiss(animated: true, completion: nil) 
    print("Sign in dismissed") 
} 



override func viewDidAppear(_ animated: Bool) { 
    self.performSegue(withIdentifier: "loginView", sender: self); //this line is where the Thread 1: Breakpoint 3.1 was. 


} 

} 

我不久問題:

- 在模擬器上的按鈕不起作用

- 的simulatior崩潰,並顯示在Xcode的代碼序列我跟他說主題1日前顯示:SIGABRT和線程1:最後一行中的斷點3.1。

您認爲問題是什麼,我該如何解決? 編輯 嘗試啓動模擬器時我收到此:

您確定,您的segue在InterfaceBuilder中有正確的名稱嗎?另外,你爲什麼要在viewDidAppear中執行segue? –

不要忘記調用'super.viewDidAppear()'。 – shallowThought

我在ViewController中有segue,因爲那是Google開發者告訴我的。我使用override func viewDidAppear在視圖控制器中粘貼了super.viewDidAppear(),但它給了紅色的警告標誌。我應該把它放在哪裏? –

我有同樣的問題在Xcode 9和模擬器終止。 我使用了iOS 11的真實設備,它工作正常(雖然有一些錯誤)
