近来在做关于Google、Twitter、Facebook登录和注册的相关项目中遇到不少坑，下面就简单记录一下操作和相关代码
首先我们需要导入对应的三房库
3.png
- 1 Google
登录
注册获取key和id
下面是我们注册好的
1.png
在注册完成后，我们将GoogleService-Info.plist文件下载下来，然后倒入工程，检查是不是和我们申请的key和id保持一致
2.png
现在我们差不多配置好了所需要的key和id
下面我们之间上代码
Google登录
#import
#import
#import
#import
...
//需和plit文件中的id保持一致
static NSString *const kGoogleId = @"1096539491378-53v42rvea90r1rjap674qc3jviob2b36.apps.googleusercontent.com";
static NSString *const kGooglesecret = @"";//此处秘钥如果你的id是web client则需要 否则可以不填
@interface LoginViewController ()
{
GPPSignIn * _signin;
UINavigationController * _googleLoginNavigationController;
}
#pragma mark == GPPSignInDelegate
//定义以下方法，在视图控制器中实施 GPPSignInDelegate 以处理登录流程。
- (void)finishedWithAuth: (GTMOAuth2Authentication *)auth
error: (NSError *) error
{
//根据google回调的信息 进行自己服务器的登录
GTLQueryPlus *query = [GTLQueryPlus queryForPeopleGetWithUserId:@"me"];
NSLog(@"email %@ ", [NSString stringWithFormat:@"Email: %@",[GPPSignIn sharedInstance].authentication.userEmail]);
NSLog(@"Received error %@ and auth object %@",error, auth);
// 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";
__weak typeof(self)weakSelf = self;
[plusService executeQuery:query
completionHandler:^(GTLServiceTicket *ticket,
GTLPlusPerson *person,
NSError *error) {
__strong __typeof(weakSelf)strongSelf = weakSelf;
if (error) {
//Handle Error
} else {
NSLog(@"Email= %@", [GPPSignIn sharedInstance].authentication.userEmail);
NSLog(@"GoogleID=%@", person.identifier);
NSLog(@"User Name=%@", [person.name.givenName stringByAppendingFormat:@" %@", person.name.familyName]);
NSLog(@"Gender=%@", person.gender);
}
}];
}
- (void)googleLogin
{
void (^handler)(id, id, id) =
^(GTMOAuth2ViewControllerTouch *viewController,
GTMOAuth2Authentication *auth,
NSError *error) {
[self dismissViewControllerAnimated:YES completion:^{
}];
if (error) {
NSLog(@"%@", error);
return;
} else {
BOOL signedIn = [[GPPSignIn sharedInstance] trySilentAuthentication];
if(!signedIn) {
NSLog(@"Sign In failed");
}
}
};
GTMOAuth2ViewControllerTouch *authViewController;
authViewController = [GTMOAuth2ViewControllerTouch
controllerWithScope:kGTLAuthScopePlusLogin
clientID:[GPPSignIn sharedInstance].clientID
clientSecret:kGooglesecret
keychainItemName:[GPPSignIn sharedInstance].keychainName
completionHandler:handler];
authViewController.initialHTMLString = @"Are entering Google login page...";
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:authViewController];
navigationController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
_googleLoginNavigationController = navigationController;
[self.navigationController presentViewController:navigationController animated:YES completion:nil];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1f * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Cancel", nil)
style:UIBarButtonItemStylePlain
target:self
action:@selector(didCanceledAuthorization)];
authViewController.navigationItem.rightBarButtonItem = nil;
authViewController.navigationItem.leftBarButtonItem = cancelButton;
authViewController.navigationItem.title = @"Google Login";
});
}
- (void)didCanceledAuthorization
{
[_googleLoginNavigationController dismissModalController];
}
12月16补充说明：最近之前的google登录方式不行了。在官网上找到最新代码，贴在此处以供大家享用
//这个和之前的唯一不同的是需要在info.plist文件中 在 URL Schemes中添加 googlesevice.plist中的 REVERSED_CLIENT_ID的值
- (void)viewDidLoad {
[super viewDidLoad];
[GIDSignIn sharedInstance].shouldFetchBasicProfile = YES;
[GIDSignIn sharedInstance].delegate = self;//设置代理，这个是结果回调
[GIDSignIn sharedInstance].uiDelegate = self;//设置代理，这个是调用授权登录页面的
[[GIDSignIn sharedInstance] signOut];//注销之前的登录状态
}
- (void)googleLogin
{
//调用google登录API
[[GIDSignIn sharedInstance] signIn];
}
#pragma mark - GIDSignInDelegate
- (void)signIn:(GIDSignIn *)signIn
didSignInForUser:(GIDGoogleUser *)user
withError:(NSError *)error {
if (error) {
// _signInAuthStatus.text = [NSString stringWithFormat:@"Status: Authentication error: %@", error];
return;
}
// [self reportAuthStatus];
// [self updateButtons];
//下面为登录后获取的相关信息
NSString *email = [GIDSignIn sharedInstance].currentUser.profile.email;
NSString *givename = [GIDSignIn sharedInstance].currentUser.profile.givenName;
NSString *familyName = [GIDSignIn sharedInstance].currentUser.profile.familyName;
}
- (void)signIn:(GIDSignIn *)signIn
didDisconnectWithUser:(GIDGoogleUser *)user
withError:(NSError *)error {
if (error) {
// _signInAuthStatus.text = [NSString stringWithFormat:@"Status: Failed to disconnect: %@", error];
} else {
// _signInAuthStatus.text = [NSString stringWithFormat:@"Status: Disconnected"];
}
// [self reportAuthStatus];
// [self updateButtons];
NSString *email = [GIDSignIn sharedInstance].currentUser.profile.email;
NSString *givename = [GIDSignIn sharedInstance].currentUser.profile.givenName;
NSString *familyName = [GIDSignIn sharedInstance].currentUser.profile.familyName;
}
- (void)presentSignInViewController:(UIViewController *)viewController {
[[self navigationController] pushViewController:viewController animated:YES];
}
GoogleMaps
首先可以用cocoapods导入库
pod 'GoogleMaps', '~> 1.13.2'
然后在AppDelegate加入以下代码
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//地图 key和plist文件中的是一样的如上图中的 A....oUYKD5swJDFt5w
[GMSServices provideAPIKey:GOOGLE_MAP_APIKEY];
services_ = [GMSServices sharedServices];
}
关于地图具体怎么用，这里就不在详细说明了
- 2 Facebook
先在plist文件中设置
5.png
然后在AppDelegate加入以下代码
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//facebook
[[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
return YES;
}
在要分享的地方 导入头文件 并执行以下代码
#import
....
- (void)ShareFacebook
{
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentURL = [NSURL URLWithString:@"http://www.baidu.com"];
content.contentTitle = @"分享标题";
content.contentDescription = @"Is a good restaurant";
content.imageURL = [NSURL URLWithString:@"分享图片"];
[FBSDKShareDialog showFromViewController:self withContent:content delegate:(id)self];
}
//分享回调代理
#pragma mark == facebook shareDelegate
- (void)sharer:(id)sharer didCompleteWithResults:(NSDictionary *)results
{
//分享成功
}
- (void)sharer:(id)sharer didFailWithError:(NSError *)error
{
//失败
}
- (void)sharerDidCancel:(id)sharer
{
//取消
}
在登录的地方 导入头文件
#import
#import
登录的时候 执行以下函数
- (void)facebookLogin
{
__weak typeof(self)weakSelf = self;
//已经登录过
if ([FBSDKAccessToken currentAccessToken])
{
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logOut];
}
else
{
//@"publish_actions"
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
//获取对应的信息 email 等
[login logInWithReadPermissions:@[@"public_profile",@"email",@"user_friends"]
fromViewController:self
handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
return;
}
if ([FBSDKAccessToken currentAccessToken] &&
[[FBSDKAccessToken currentAccessToken].permissions containsObject:@"public_profile"]) {
//登录成功 获取信息
[weakSelf getFacebookUserinfo];
NSLog(@" 打印信息:%@",[FBSDKAccessToken currentAccessToken].tokenString);
return;
}
}];
}
}
- (void)getFacebookUserinfo
{
NSMutableDictionary* parameters = [NSMutableDictionary dictionary];
[parameters setValue:@"id,name,email" forKey:@"fields"];
FBSDKGraphRequest *graphRequest = [[FBSDKGraphRequest alloc]initWithGraphPath:@"me" parameters:parameters];
[graphRequest startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id loginresult, NSError *error) {
if (error) {
return ;
}
else
{
NSDictionary *faceLoginDic = (NSDictionary *)loginresult;
NSLog(@" 打印信息facebook_email:%@",faceLoginDic);
//服务器登录
}
}];
}
- 3 Twitter
先去官网注册账号，并且通过Twitter的fabric导入库
12.png
//twitter
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[TwitterKit startWithConsumerKey:@"Twitter-key"
consumerSecret:@"Twitter 秘钥"];
[Fabric with:@[TwitterKit]];//通过这个集成Twitter 应该是
//CrashlyticsKit这是一个可以手机崩溃信息的
}
下面是登录和分享，Twitter的分享好像是要先进行登录，所以这里就弄成一起
先导入头文件
#import
#import
然后在分享的时候 执行下面的函数
- (void)TwitterShare
{
NSURL *imageUrlString = [NSURL URLWithString:self.restaurantListData.img];
NSData *imageData = [NSData dataWithContentsOfURL:imageUrlString];
UIImage *image = [UIImage imageWithData:imageData];
[[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session, NSError *error) {
if (session) {
//登录成功
TWTRComposer *composer = [[TWTRComposer alloc] init];
[composer setText:self.restaurantListData.restaurantname];
[composer setImage:image];
[composer showWithCompletion:^(TWTRComposerResult result) {
if (result == TWTRComposerResultCancelled) {
NSLog(@"Tweet composition cancelled");
}
else {
}
}];
NSLog(@"signed in as %@", [session userName]);
} else {
NSLog(@"error: %@", [error localizedDescription]);
}
}];
}
以上就是关于这些的一个坑，地图这块没写，等有空了就写一个，现在要准备面试了，明天还要面试。有什么不对的，还请多多指教，大家一起共同进步 -.
