第四十一篇：微信第三方登录

登录前效果图：

登录后效果图：

一、准备工作

第一步：下载友盟SDK，下载友盟SDK 根据需要选择下载，下载完成后把 UMSocial 文件添加到工程中；

第二步：添加配置，在 Build Settings --> Linking --> Other Linker Flags --> Debug 或 Release 对应的行后加入-ObjC ，注意不要写为-Objc

第三步：在项目的.plist 文件中添加如下配制，使允许网络加载

第四步：添加在项目中的所有 SDK 所需的 依懒库，下列是一些常见的登录或分享所需的依懒库

libsqlite3.tbd        // 这两个是必须添加的CoreGraphics.framework // 微信的依懒库SystemConfiguration.frameworkCoreTelephony.frameworklibsqlite3.tbdlibc++.tbdlibz.tbd// QQ 的依懒库SystemConfiguration.frameworklibc++.tbd // 新浪微博的依懒库CoreTelephony.frameworkImageIO.frameworklibsqlite3.tbdlibz.tbd // 短信 的依懒库MessageUI.framework

第五步：配制SSO白名单

         如果你的应用使用了如SSO授权登录或跳转到第三方分享功能，在iOS9/10下就需要增加一个可跳转的白名单，即LSApplicationQueriesSchemes，否则将在SDK判断是否跳转时用到的canOpenURL时返回NO，进而只进行webview授权或授权/分享失败。 在项目中的info.plist中加入应用白名单，右键info.plist选择source code打开(plist具体设置在Build Setting -> Packaging -> Info.plist File可获取plist路径) 请根据选择的平台对以下配置进行裁剪：

<key>LSApplicationQueriesSchemes</key><array>    <!-- 微信 URL Scheme 白名单-->    <string>wechat</string>    <string>weixin</string>    <!-- 新浪微博 URL Scheme 白名单-->    <string>sinaweibohd</string>    <string>sinaweibo</string>    <string>sinaweibosso</string>    <string>weibosdk</string>    <string>weibosdk2.5</string>    <!-- QQ、Qzone URL Scheme 白名单-->    <string>mqqapi</string>    <string>mqq</string>    <string>mqqOpensdkSSoLogin</string>    <string>mqqconnect</string>    <string>mqqopensdkdataline</string>    <string>mqqopensdkgrouptribeshare</string>    <string>mqqopensdkfriend</string>    <string>mqqopensdkapi</string>    <string>mqqopensdkapiV2</string>    <string>mqqopensdkapiV3</string>    <string>mqqopensdkapiV4</string>    <string>mqzoneopensdk</string>    <string>wtloginmqq</string>    <string>wtloginmqq2</string>    <string>mqqwpa</string>    <string>mqzone</string>    <string>mqzonev2</string>    <string>mqzoneshare</string>    <string>wtloginqzone</string>    <string>mqzonewx</string>    <string>mqzoneopensdkapiV2</string>    <string>mqzoneopensdkapi19</string>    <string>mqzoneopensdkapi</string>    <string>mqqbrowser</string>    <string>mttbrowser</string>    <!-- 支付宝 URL Scheme 白名单-->    <string>alipay</string>    <string>alipayshare</string>    <!-- 钉钉 URL Scheme 白名单-->      <string>dingtalk</string>      <string>dingtalk-open</string>    <!--Linkedin URL Scheme 白名单-->    <string>linkedin</string>    <string>linkedin-sdk2</string>    <string>linkedin-sdk</string>    <!-- 点点虫 URL Scheme 白名单-->    <string>laiwangsso</string>    <!-- 易信 URL Scheme 白名单-->    <string>yixin</string>    <string>yixinopenapi</string>    <!-- instagram URL Scheme 白名单-->    <string>instagram</string>    <!-- whatsapp URL Scheme 白名单-->    <string>whatsapp</string>    <!-- line URL Scheme 白名单-->    <string>line</string>    <!-- Facebook URL Scheme 白名单-->    <string>fbapi</string>    <string>fb-messenger-api</string>    <string>fbauth2</string>    <string>fbshareextension</string>    <!-- Kakao URL Scheme 白名单-->      <!-- 注：以下第一个参数需替换为自己的kakao appkey-->     <!-- 格式为 kakao + "kakao appkey"-->        <string>kakaofa63a0b2356e923f3edd6512d531f546</string>    <string>kakaokompassauth</string>    <string>storykompassauth</string>    <string>kakaolink</string>    <string>kakaotalk-4.5.0</string>    <string>kakaostory-2.9.0</string>   <!-- pinterest URL Scheme 白名单-->      <string>pinterestsdk.v1</string>   <!-- Tumblr URL Scheme 白名单-->      <string>tumblr</string>   <!-- 印象笔记 -->    <string>evernote</string>    <string>en</string>    <string>enx</string>    <string>evernotecid</string>    <string>evernotemsg</string>   <!-- 有道云笔记-->    <string>youdaonote</string>    <string>ynotedictfav</string>    <string>com.youdao.note.todayViewNote</string>    <string>ynotesharesdk</string>   <!-- Google+-->    <string>gplus</string>   <!-- Pocket-->    <string>pocket</string>    <string>readitlater</string>    <string>pocket-oauth-v1</string>    <string>fb131450656879143</string>    <string>en-readitlater-5776</string>    <string>com.ideashower.ReadItLaterPro3</string>    <string>com.ideashower.ReadItLaterPro</string>    <string>com.ideashower.ReadItLaterProAlpha</string>    <string>com.ideashower.ReadItLaterProEnterprise</string>   <!-- VKontakte-->    <string>vk</string>    <string>vk-share</string>    <string>vkauthorize</string></array>

第六步：在项目的 plist 文件中配制 URL Scheme

二、实现第三方登录功能

       前言：现在已经有了一个空项目里面有一个友盟SDK，并做了相关的配制后，接下来就是要实现该功能。在实现之前需要自己去申请一个友盟AppKey。

1.创建一个公共的文件 CommentHeader.h ，用来存放 key 值

////  CommentHeader.h//  QJWeixinLogin////  Created by 瞿杰 on 2017/6/15.//  Copyright © 2017年 yiniu.
