我在他們的登錄按鈕上的谷歌文檔掙扎。基本上,我想在按下谷歌登錄按鈕後立即在屏幕上添加一個活動指示器。然而,只有兩個是真的會從文檔下文稱爲谷歌登錄按鈕按檢測ios

https://developers.google.com/identity/sign-in/ios/api/protocol_g_i_d_sign_in_u_i_delegate-p#a3674af917a79f4b87a58f3f8ff4d4002

  1. - signInWillDispatch:error:

    功能登錄流程完成選擇如何進行,以及用戶界面應該不再顯示一個微調框或其他「請稍等」的元素。更多...

  2. - signIn:didSignInForUser:withError:

    的登錄流程已經完成,並已成功如果錯誤是零。更多...`

我不知道在哪裏我可以把我的beginActivityIndi​​cator代碼,我不知道什麼函數被調用後,我立刻按谷歌登錄按鈕。

感謝,

代碼爲--update - 下面是我在我的loginVC從GIDSignInUIDelegate和GIDSignInDelegate繼承四大功能。幾乎我需要在SignInWillDispatch之前訪問函數,以便啓動活動指示器。但是,我無法找到它在文檔中的位置。我嘗試在Google按鈕上添加輕觸手勢識別器。當我這樣做時,登錄功能完全停止工作,就好像它只是一個空白UIView

// Google login buttob 
    GIDSignIn.sharedInstance().uiDelegate = self 
    GIDSignIn.sharedInstance().delegate = self 


    // Uncomment to automatically sign in the user. 
    //GIDSignIn.sharedInstance().signInSilently() 

    // TODO(developer) Configure the sign-in button look/feel 
    let googleSignInBtn = GIDSignInButton() 
    googleSignInBtn.frame.size = loginButton.frame.size 
    googleSignInBtn.center.x = loginButton.center.x 
    googleSignInBtn.center.y = loginButton.center.y + 80 
    googleSignInBtn.style = .Wide 
    self.view.addSubview(googleSignInBtn) 



func signIn(signIn: GIDSignIn!, presentViewController viewController: UIViewController!) { 
    print("Signed in with google") 
} 

func signInWillDispatch(signIn: GIDSignIn!, error: NSError!) { 
    print("Signin Will Dispatch") 
} 

func signIn(signIn: GIDSignIn!, dismissViewController viewController: UIViewController!) { 
    print("GoogleSignInDismiss") 
} 

func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!, withError error: NSError!) { 

    activityIndicatorBegin() // Having the activity indicator start here is too late. I need it to start as soon as the google button is pressed. Otherwise there would be a moment just after the google view dismisses without activity indicator 

    if let error = error { 
     print(error.localizedDescription) 
     return 
    } 

    let authentication = user.authentication 
    let credential = FIRGoogleAuthProvider.credentialWithIDToken(authentication.idToken, accessToken: authentication.accessToken) 

    FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in 
     if let error = error { 
      self.showErrorAlert("Error Sign in Firebase with google", message: error.localizedDescription) 
     } else { 

     } 
     self.activityIndicatorEnd() 
    } 
} 

func signIn(signIn: GIDSignIn!, didDisconnectWithUser user:GIDGoogleUser!, withError error: NSError!) { 
    // Perform any operations when the user disconnects from app here. 
    print("didDisconnectWithUser") 
}

代碼張貼上尉。我確實通過了開發人員指導,這裏是我卡住的地方。乾杯 – user172902

問題解決了。通過像上面那樣編程式地創建按鈕,我無法解決它。我所做的就是創建一個UIButton和根本就以下

@IBAction func signInWithGoogleBtn(sender: AnyObject) { 
    activityIndicatorBegin() 
    GIDSignIn.sharedInstance().signIn() 
}
