ios - Google 登录按钮什么都不做

Question

我已经完全按照 Google 根据其网站声明的方式实现了 Google 登录。我大约一个月前让它工作，现在它什么都不做。我试图通过删除 cocoapod 并关注他们的网站到 T 来重做所有事情，但仍然没有任何反应。好像没有调用任何委托(delegate)方法，我不确定为什么。任何帮助将不胜感激。谢谢!

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

    //Get Twitter and set Twitter keys for Application
    Twitter.sharedInstance().startWithConsumerKey("uBedaxDuMDgImGbjun1oYf0ay", consumerSecret: "OaKqBZUesX5CypHCwrTvTZE22jrXIuRsUeZzVaMHej11R5Vh3b")
    Fabric.with([Twitter.self])

    // Initialize sign-in GOOGLE
    var configureError: NSError?
    GGLContext.sharedInstance().configureWithError(&configureError)
    assert(configureError == nil, "Error configuring Google services: \(configureError)")

    GIDSignIn.sharedInstance().delegate = self

    return true
}

func application(application: UIApplication,
                 openURL url: NSURL, options: [String: AnyObject]) -> Bool {
    return GIDSignIn.sharedInstance().handleURL(url,
                                                sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String,
                                                annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
}

func application(application: UIApplication,
                 openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
    var options: [String: AnyObject] = [UIApplicationOpenURLOptionsSourceApplicationKey: sourceApplication!,
                                        UIApplicationOpenURLOptionsAnnotationKey: annotation!]
    return GIDSignIn.sharedInstance().handleURL(url,
                                                sourceApplication: sourceApplication,
                                                annotation: annotation)
}

func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!,
            withError error: NSError!) {
    print("SIGNING IN")
    if (error == nil) {
        let email = user.profile.email
        print(user.authentication)
        // ...
    } else {
        print("ERROR = \(error.localizedDescription)")
    }
}

View Controller

import GoogleSignIn
class LoginViewController: UIViewController, UITextFieldDelegate, CLLocationManagerDelegate, GIDSignInUIDelegate
 override func viewDidLoad() {

    //Default setup for View Controller
    super.viewDidLoad()

    GIDSignIn.sharedInstance().uiDelegate = self
    var error:NSError?
    GGLContext.sharedInstance().configureWithError(&error)
    if(error != nil) {
        print(error)
    }

    var signInButton = GIDSignInButton(frame: CGRect(x: 0, y: 0, width: 150, height: 400))
    view.addSubview(signInButton)

}  

编辑

HOURS 之后，大声笑，弄清楚了这一点后，Google 登录按钮就可以正常工作了 1)按住2秒以上， 2)向左/向下/向右滑动但不向上滑动 我不确定这个原因，愿意接受建议!谢谢!

我遇到了同样的问题，这是绑定(bind)到主视图以关闭键盘的点击手势识别器的问题。它不小心也捕获了 GIDSignInButton 内部的触摸。更改此设置有帮助:

tapGesture.cancelsTouchesInView = false
