本文介绍在iOS上集成Google和Apple三方登录的开发指南。
Google登录
- 创建项目
- Xcode工程配置
在xcode工程的
info.plist文件中配置url scheme，URL Schemes参数填Google生成plist文件中的REVERSED_CLIENT_ID。
代码示例
#import <ALBBOpenAccountSSO/ALBBOpenAccountSSOService.h>
#import <ALBBOpenAccountCloud/ALBBOpenAccountSDK.h>
//Google生成plist文件中的CLIENT_ID
static NSString * const IMSAuthPlatformGoogleAppKey = @"xxxx.apps.googleusercontent.com";
@implementation GoogleLoginDemo
- (instancetype)init {
self = [super init];
if (self) {
//登录成功通知
[IMSNotification addObserverForName:ALBBOpenAccountNotificationUserLoggedIn object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification * _Nonnull note) {
if (note.object != nil && ([note.object isEqualToString:ALBBOpenAccountNotificationTrigerByREG] || [note.object isEqualToString:ALBBOpenAccountNotificationTrigerByLogin])) {
}
}];
}
return self;
}
//拉起Google授权登录
- (void)thirdAuthorizationLogin {
id<ALBBOpenAccountSSOService> ssoService = ALBBService(ALBBOpenAccountSSOService);
//初始化
[ssoService setPlatform:OAAuthPlatformType_Google
appKey:IMSAuthPlatformGoogleAppKey
appSecret:nil
redirectURL:nil];
//三方账号授权登录
[ssoService oauthWithPlatForm:OAAuthPlatformType_Google
presentingVC:self
delegate:self];
}
#pragma mark - SSODelegate
- (void)openAccountOAuthError:(NSError *)error Session:(ALBBOpenAccountSession *)session {
if (error && error.code != -5) {
//处理授权登录错误
}
}
@end- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
NSString *sourceApplication = [options objectForKey:UIApplicationOpenURLOptionsSourceApplicationKey];
id annotation = [options objectForKey:UIApplicationOpenURLOptionsAnnotationKey];
return [ALBBService(ALBBOpenAccountSSOService) handleOpenUrl:url application:app
sourceApplication:sourceApplication annotation:annotation];
}Apple登录
项目配置
- 在苹果开发者网站，开通sign in with Apple。
- 在Xcode中添加sign in with Apple。
选中target，在Signing & Capabilities中点击Capability选择sign in with Apple。
代码示例
#import <ALBBOpenAccountSSO/ALBBOpenAccountSSOService.h>
#import <ALBBOpenAccountCloud/ALBBOpenAccountSDK.h>
#import <IMSApiClient/IMSConfiguration.h>
