ios 三方登录(qq、微信)

qq三方登录

1.前往腾讯开放平台注册帐号并创建应用提交审核

1.1 创建应用（帐号的注册此处不做说明）

1.1

1.2 选择iOS，并留意APP ID;APP KEY(后面需要用到)

1.2

1.3 填写相应的信息并保存、提交（一般来说这个审核几个小时内就会通过）

1.3

1.4 审核通过后->管理中心->点击已获取QQ登录能力的应用->点击QQ登录->填写调试者qq

1.41

1.42

2. 导入SDK: 点我下载，并进行相关配置

2.1 下载后将TencentOpenAPI.framework和TencentOpenApi_iOS_Bundle.bundle拖入你的项目

2.1

2.2 添加依赖库

点击Project navigator 点击TARGETS -> General -> Linked Frameworks and Libraries->点击加号添加

2.2

需要添加的依赖库：

”Security.framework”;“libiconv.tbd”;“SystemConfiguration.framework”;“CoreGraphics.Framework”;“libsqlite3.tbd”;“CoreTelephony.framework”;“libstdc++.tbd”;“libz.tbd”。

2.3 修改配置属性

点击Project navigator 点击TARGETS -> Build Settings ->Linking->Other Linker Flags->点击加号添加属性值“-fobjc-arc”

2.3

2.4 添加URL Scheme

点击Project navigator 点击TARGETS ->info ->URL type-> 添加URL type

Identifier 填写：tencentopenapi

URL Scheme填写： tencent +APP ID(APP ID: 从上文1.2中科获得)

：你的APP ID是1234567 则填入tencent1234567

2.4

2.5 ios9以后，需要添加白名单

在info.plist文件中加入 LSApplicationQueriesSchemes

2.5

2.6 针对iOS9默认使用https,现在先还原成http请求方式

第一步：在plist中添加NSAppTransportSecurity项，此项为NSDictionary

第二步：在NSAppTransportSecurity下添加 NSAllowsArbitraryLoads类型为Boolean，value为YES

2.6

3.代码区

3.1 在Appdelegate.m中

导入并重写两个方法

#import

- (BOOL)application:(UIApplication*)application openURL:(NSURL*)url sourceApplication:(NSString*)sourceApplication annotation:(id)annotation{return[TencentOAuth HandleOpenURL:url];}- (BOOL)application:(UIApplication*)application handleOpenURL:(NSURL*)url{return[TencentOAuth HandleOpenURL:url];}

3.2 在ThirdLogin.m(用于封装三方登录的类)中

#import"ThirdLogin.h"#import#import"HttpClient.h"#define NAME @"name"#define PICTURE @"picture"#define OPENID @"openId"@interfaceThirdLogin(){ TencentOAuth *tencentOAuth;NSArray*permissions;}@property(copy,nonatomic)void(^success)(NSDictionary*result);@property(copy,nonatomic)void(^failure)(NSError*error);@end@implementationThirdLogin#pragma mark--------------------------------------------------------#pragma mark qq三方登录// 对外的api: 即点击qq三方登录按钮，调这个方法- (void)qqLoginWithSuccess:(void(^)(NSDictionary*userInfo))success failure:(void(^)(NSError*error))failure {// 成功或失败的回调block self.success = [successcopy];self.failure = [failurecopy];// 需要放在主线程中执行 dispatch_async(dispatch_get_main_queue(), ^{ tencentOAuth=[[TencentOAuth alloc]initWithAppId:@"1105549185"andDelegate:self];// 设置需要的权限列表，此处尽量使用什么取什么。permissions= [NSArrayarrayWithObjects:kOPEN_PERMISSION_GET_USER_INFO, kOPEN_PERMISSION_GET_SIMPLE_USER_INFO,@"add_t",nil]; [tencentOAuth authorize:permissions]; });}- (BOOL)tencentNeedPerformIncrAuth:(TencentOAuth *)tencentOAuth withPermissions:(NSArray*)permissions {returnYES;}#pragma mark -- TencentSessionDelegate//登陆完成调用- (void)tencentDidLogin{if(tencentOAuth.accessToken &&0!= [tencentOAuth.accessToken length]) {// 记录登录用户的OpenID、Token以及过期时间[tencentOAuth getUserInfo]; }else{ [selffailureWith:@"未授权成功"]; }}//非网络错误导致登录失败：-(void)tencentDidNotLogin:(BOOL)cancelled{if(cancelled){ [selffailureWith:@"用户取消登录"]; }else{ [selffailureWith:@"登录失败"]; }}// 网络错误导致登录失败：-(void)tencentDidNotNetWork { [selffailureWith:@"网络错误"];}- (void)tencentDidLogout{// NSLog(@"登出");}-(void)getUserInfoResponse:(APIResponse *)response {NSDictionary*result = [NSDictionarydictionaryWithObjectsAndKeys:[response.jsonResponse objectForKey:@"nickname"], [response.jsonResponse objectForKey:@"figureurl_qq_2"], tencentOAuth.openId, NAME, PICTURE, OPENID,nil];self.success(result);}- (void)failureWith:(NSString*)domin {NSError*error = [NSErrorerrorWithDomain:domin code:0userInfo:nil];self.failure(error);}

补充：

登陆成功的方法里面调用[tencentOAuth getUserInfo];然后系统会调用一个方法（我们需要提前实现）-(void)getUserInfoResponse:(APIResponse*)response{}

在getUserInfoResponse中可以得到所需要的用户信息

微信三方登录

1.前往微信开放平台注册帐号并创建应用提交审核

在微信开放平台注册开发者帐号并创建应用，审核通过后，获得相应的AppID和AppSecret，基本流程和qq三方登录类似（这里不做说明）

2. 导入SDK: 点我下载，并进行相关配置

2.1 下载后将下面文件导入工程目录中

2.1

2.2 添加依赖库

2.2

需要添加的依赖库：

“SystemConfiguration.framework”;“CoreTelephony.framework”;“libsqlite3.0.tbd”;“libstdc++.tbd”;“libz.tbd”;"libWeChatSDK.a"

2.3 添加URL Scheme

点击Project navigator 点击TARGETS ->info ->URL type-> 添加URL type

Identifier 填写：可自定义

URL Scheme填写： APP ID(APP ID: 从上文1.2中科获得)

：你的APP ID是wx1234567 则填入wx1234567

2.3

2.4 ios9以后，需要添加白名单

在info.plist文件中加入 LSApplicationQueriesSchemes

2.4

2.5 针对iOS9默认使用https,现在先还原成http请求方式

第一步：在plist中添加NSAppTransportSecurity项，此项为NSDictionary

补充：

access_token 接口调用凭证

refresh_token 用户刷新access_token

openid 授权用户唯一标识

access_token有效期为2小时，当再次登陆时通过refresh_token进行刷新，有两种情况：

access_token未超时，access_token不会改变，但超时时间会刷新，相当于续期access_token。

超时,那么会获取一个新的access_token，新的超时时间;

注：refresh_token拥有有效期:30天
