请问有人可以指导我该如何做吗？我不能使用Google+登录按钮，因为"Google+登录已经过时了"。
编辑：- 我尝试了下面链接中提供的代码：
https://developers.google.com/identity/sign-in/ios/sign-in#add_the_sign-in_button
你可以添加自己的按钮，而不是使用Google登录按钮 请按照以下步骤操作
1）在storyboard中添加自己的按钮
2）将动作拖入视图控制器
- (IBAction)googlePlusButtonTouchUpInside:(id)sender {
[GIDSignIn sharedInstance].delegate = self;
[GIDSignIn sharedInstance].uiDelegate = self;
[[GIDSignIn sharedInstance] signIn];
}
3) 处理委托方法
#pragma mark - Google SignIn 委托
- (void)signInWillDispatch:(GIDSignIn *)signIn error:(NSError *)error {
}
// 展示一个视图，提示用户使用 Google 登录
- (void)signIn:(GIDSignIn *)signIn presentViewController:(UIViewController *)viewController
{
[self presentViewController:viewController animated:YES completion:nil];
}
// 关闭 "使用 Google 登录" 视图
- (void)signIn:(GIDSignIn *)signIn dismissViewController:(UIViewController *)viewController {
[self dismissViewControllerAnimated:YES completion:nil];
}
//完成登录
- (void)signIn:(GIDSignIn *)signIn didSignInForUser:(GIDGoogleUser *)user
withError:(NSError *)error {
//user signed in
//get user data in "user" (GIDGoogleUser object)
}
在 Swift 中，确保您添加了桥接头文件，因为该库是用 Objective-C 编写的。
1）将您自己的按钮添加到故事板中。
2）将操作拖入视图控制器中。
@IBAction func googlePlusButtonTouchUpInside(sender: AnyObject) {
GIDSignIn.sharedInstance().delegate=self
GIDSignIn.sharedInstance().uiDelegate=self
GIDSignIn.sharedInstance().signIn()
}
3) 处理委托方法
//MARK: Google SignIn 委托
func signInWillDispatch(_ signIn: GIDSignIn!, error: Error!) {
}
// 呈现一个视图，提示用户使用谷歌账号登录
func signIn(_ signIn: GIDSignIn!,
presentViewController viewController: UIViewController!) {
self.present(viewController, animated: true, completion: nil)
}
// 关闭“使用 Google 登录”视图
func signIn(_ signIn: GIDSignIn!,
dismissViewController viewController: UIViewController!) {
self.dismiss(animated: true, completion: nil)
}
//登录完成
public func signIn(_ signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!,
withError error: Error!) {
if (error == nil) {
// Perform any operations on signed in user here.
let userId = user.userID // For client-side use only!
let idToken = user.authentication.idToken // Safe to send to the server
let fullName = user.profile.name
let givenName = user.profile.givenName
let familyName = user.profile.familyName
let email = user.profile.email
// ...
} else {
print("\(error.localized)")
}
}
编辑：这是使用自定义按钮的参考/证据，Google文档参考
在这些示例中，视图控制器是UIViewController的子类。如果在您的项目中，实现GIDSignInUIDelegate的类不是UIViewController的子类，请实现GIDSignInUIDelegate协议的signInWillDispatch:error:、signIn:presentViewController:和signIn:dismissViewController:方法。还要记得设置UI代理 GIDSignIn.sharedInstance()?.uiDelegate = self
Swift 3 版本
在 Swift 中，确保添加了桥接头文件，因为该库是用 Objective C 编写的。
drag action into viewController
@IBAction func googlePlusButtonTouchUpInside(sender: AnyObject) {
GIDSignIn.sharedInstance().signIn()
}
handle delegate methods
//MARK:Google SignIn Delegate
func signInWillDispatch(signIn: GIDSignIn!, error: NSError!) {
// myActivityIndicator.stopAnimating()
}
// Present a view that prompts the user to sign in with Google
func sign(_ signIn: GIDSignIn!,
present viewController: UIViewController!) {
self.present(viewController, animated: true, completion: nil)
}
// Dismiss the "Sign in with Google" view
func sign(_ signIn: GIDSignIn!,
dismiss viewController: UIViewController!) {
self.dismiss(animated: true, completion: nil)
}
//completed sign In
public func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
if (error == nil) {
// Perform any operations on signed in user here.
let userId = user.userID // For client-side use only!
let idToken = user.authentication.idToken // Safe to send to the server
let fullName = user.profile.name
let givenName = user.profile.givenName
let familyName = user.profile.familyName
let email = user.profile.email
// ...
} else {
print("\(error.localizedDescription)")
}
}
针对Swift 4: （这是可用的代码，享受吧）
@IBAction func logimByGoogle(_ sender: Any) {
GIDSignIn.sharedInstance().delegate = self
GIDSignIn.sharedInstance().uiDelegate = self
GIDSignIn.sharedInstance().signIn()
}
//MARK:- Google Delegate
func sign(inWillDispatch signIn: GIDSignIn!, error: Error!) {
}
func sign(_ signIn: GIDSignIn!,
present viewController: UIViewController!) {
self.present(viewController, animated: true, completion: nil)
}
public func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!,
withError error: Error!) {
if (error == nil) {
// Perform any operations on signed in user here.
let userId = user.userID // For client-side use only!
let idToken = user.authentication.idToken // Safe to send to the server
let fullName = user.profile.name
let givenName = user.profile.givenName
let familyName = user.profile.familyName
let email = user.profile.email
// ...
} else {
print("\(error)")
}
}
关于@Rohit KP (https://dev59.com/IlsX5IYBdhLWcg3wALXa#34368678)的答案都是正确的。
但是在分配代理时还需要添加一些内容。
请按照以下方式调用您的操作:
- (IBAction)btnGooglePlusPressed:(id)sender
{
[GIDSignIn sharedInstance].delegate=self;
[GIDSignIn sharedInstance].uiDelegate=self;
[[GIDSignIn sharedInstance] signIn];
}
并添加这些代理 GIDSignInDelegate，GIDSignInUIDelegate
@IBAction func googleLoginPressed(sender: UIButton) {
GIDSignIn.sharedInstance()?.presentingViewController = self
GIDSignIn.sharedInstance()?.delegate = self
GIDSignIn.sharedInstance()?.signIn()
}
Swift-5 复制粘贴即可使用
@IBAction func btngoogle(_ sender: UIButton) {
GIDSignIn.sharedInstance().signIn()
}
//MARK:Google SignIn Delegate
func sign(inWillDispatch signIn: GIDSignIn!, error: Error!) {
// myActivityIndicator.stopAnimating()
}
// Present a view that prompts the user to sign in with Google
func sign(_ signIn: GIDSignIn!,
present viewController: UIViewController!) {
self.present(viewController, animated: true, completion: nil)
}
// Dismiss the "Sign in with Google" view
func sign(_ signIn: GIDSignIn!,
dismiss viewController: UIViewController!) {
self.dismiss(animated: true, completion: nil)
}
//completed sign In
public func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
if (error == nil) {
// Perform any operations on signed in user here.
let userId = user.userID // For client-side use only!
let idToken = user.authentication.idToken // Safe to send to the server
let fullName = user.profile.name
let givenName = user.profile.givenName
let familyName = user.profile.familyName
let email = user.profile.email
// ...
} else {
print("\(error.localizedDescription)")
}
}
对于Swift 4.2
制作自定义Google按钮的方法：
1-将您的按钮添加到Storyboard中
2-为您的按钮创建@IBaction
3-按照https://developers.google.com/identity/sign-in/ios/sign-in上的说明进行操作，但替换这一步骤
"2.在视图控制器中，重写viewDidLoad方法以设置GIDSignIn对象的UI委托，并（可选）尽可能静默地登录"
用以下内容代替
-> 在按钮操作中插入此代码
GIDSignIn.sharedInstance().uiDelegate=self
GIDSignIn.sharedInstance().signIn()
现在你可以愉快地自定义按钮了，希望这个回答能帮到你。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
GPPSignIn *SignIn = [GPPSignIn sharedInstance];
[GPPSignIn sharedInstance].clientID = @"532796865439-juut4g2toqdfc13mgqu5v9g5cliguvmg.apps.googleusercontent.com";
SignIn.scopes = @[kGTLAuthScopePlusLogin];
return YES;
}
-(BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
if ([GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation]) {
return YES;
}
return wasHandled;
}
ViewController.m file
@property (strong, nonatomic) IBOutlet GPPSignInButton *btn;
- (void)viewDidLoad {
[super viewDidLoad];
[GPPSignIn sharedInstance].delegate = self;
[[GPPSignIn sharedInstance] trySilentAuthentication];
AppDelegate *appDelegate = (AppDelegate *)
[[UIApplication sharedApplication] delegate];
}
-(void) finishedWithAuth:(GTMOAuth2Authentication *)auth error:(NSError *)error
{
GPPSignIn *signIn = [GPPSignIn sharedInstance];
signIn.shouldFetchGoogleUserEmail = YES;
signIn.delegate = self;
if (error == nil) {
if(auth.canAuthorize){
GTLServicePlus *service = [[GTLServicePlus alloc] init];
[service setRetryEnabled:YES];
[service setAuthorizer:auth];
GTLQueryPlus *query = [GTLQueryPlus queryForPeopleGetWithUserId:@"me"];
// 1. Create a |GTLServicePlus| instance to send a request to Google+.
GTLServicePlus* plusService = [[GTLServicePlus alloc] init] ;
plusService.retryEnabled = YES;
// 2. Set a valid |GTMOAuth2Authentication| object as the authorizer.
[plusService setAuthorizer:[GPPSignIn sharedInstance].authentication];
// 3. Use the "v1" version of the Google+ API.*
plusService.apiVersion = @"v1";
[plusService executeQuery:query
completionHandler:^(GTLServiceTicket *ticket,
GTLPlusPerson *person,
NSError *error) {
if (error) {
//Handle Error
} else {
NSLog(@"\nEmail= %@", [GPPSignIn sharedInstance].authentication.userEmail);
NSLog(@"\nGoogleID=%@", person.identifier);
NSLog(@"\nUser Name=%@", [person.name.givenName stringByAppendingFormat:@" %@", person.name.familyName]);
NSLog(@"\nGender=%@", person.gender);
}
}];
}
}
}
Swift 5.2：
Add below lines in your view controller
func googleLoginButtonPressed(sender: UIButton) {
GIDSignIn.sharedInstance()?.presentingViewController = self
GIDSignIn.sharedInstance()?.delegate = self
GIDSignIn.sharedInstance()?.signIn()
}
尝试使用Swift，它非常简单且像冠军一样有效。
为您的Google登录按钮创建引用
@IBOutlet weak var signInButton: GIDSignInButton!
在viewDidLoad中设置其样式
override func viewDidLoad() {
super.viewDidLoad()
//加载视图后进行任何其他设置。
signInButton.style = GIDSignInButtonStyle.iconOnly
3. 在主story board中将您的自定义按钮放置在Google登录按钮上方，并为其创建一个操作引用。在其中以编程方式单击Google登录按钮。
@IBAction func googleSignIn(_ sender: Any) {
signInButton.sendActions(for: .touchUpInside)
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
GPPSignIn *SignIn = [GPPSignIn sharedInstance]; [GPPSignIn sharedInstance].clientID = @"532796865439-juut4g2toqdfc13mgqu5v9g5cliguvmg.apps.googleusercontent.com"; SignIn.scopes = @[kGTLAuthScopePlusLogin];
return YES;
