關(guān)于第三方的登錄及分享，網(wǎng)上已經(jīng)有很多集成好的框架，比如友盟和Mob。但是呢，有一個(gè)地方得注意，不過(guò)這個(gè)得看產(chǎn)品經(jīng)理了，有些要求比較高，看下圖

友盟QQ登錄

集成三方框架，默認(rèn)會(huì)獲取紅框內(nèi)那些信息。不管是友盟還是Mob，都有這個(gè)問(wèn)題，這個(gè)與技術(shù)客服確認(rèn)過(guò)，說(shuō)是騰訊那邊要求的。一般我們只需要獲取用戶的基礎(chǔ)資料即可。考慮到這點(diǎn)，再加上包的大小，So，擼起袖子自己接SDK了~~

我比較懶，凡是能用cocoapods導(dǎo)入的，絕不會(huì)手動(dòng)導(dǎo)入，因?yàn)樘砑右蕾噹?kù)什么的，一不小心就bia幾崩潰了。(注意：記得把微博測(cè)試賬號(hào)添加進(jìn)去，不然授權(quán)會(huì)失敗)

• 去各個(gè)平臺(tái)注冊(cè)應(yīng)用，獲取相應(yīng)的應(yīng)用Id并在Target--> Info-->URL Types 添加各個(gè)平臺(tái)的應(yīng)用Id。
  微博：wb'你的應(yīng)用Id'
  微信：wx'你的應(yīng)用Id'
  QQ： tencent'你的應(yīng)用Id' 和 QQ'你的應(yīng)用Id轉(zhuǎn)十六進(jìn)制'

AppKey轉(zhuǎn)成十六進(jìn)制方法，直接在終端輸入
echo 'ibase=10;obase=16;您的騰訊QQ互聯(lián)應(yīng)用Id'|bc

URL Types配置

• 針對(duì)iOS9默認(rèn)使用https,現(xiàn)在先還原成http請(qǐng)求方式。

在Info.plist中添加NSAppTransportSecurity類型Dictionary。
在NSAppTransportSecurity下添加NSAllowsArbitraryLoads類型Boolean,值設(shè)為YES

• 在info里配置以下scheme

    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>mqqOpensdkSSoLogin</string>
        <string>mqzone</string>
        <string>mqq</string>
        <string>mqqapi</string>

        <string>mqqapiwallet</string>
        <string>mqqwpa</string>
        <string>mqqbrowser</string>
        <string>wtloginmqq2</string>
        <string>sinaweibo</string>
        <string>sinaweibohd</string>
        <string>sinaweibosso</string>
        <string>sinaweibohdsso</string>
        <string>weibosdk</string>
        <string>weibosdk2.5</string>
        <string>weixin</string>
        <string>wechat</string>
    </array>
 

• 導(dǎo)入sdk(cocoapods的用法這里我就不介紹了)

    pod 'TencentOpenApiSDK'
    pod 'WeiboSDK'
    pod 'WechatOpenSDK'

• 代碼接入

在AppDelegate中導(dǎo)入頭文件

這里講一下我們項(xiàng)目里的登錄流程

1.分別調(diào)用三方SDK，登錄成功后在能在回調(diào)里得到所需要的東西。微博會(huì)返回一個(gè)access_Token，微信返回一個(gè)code，QQ要返回一個(gè)code和openId。
2.把以上獲得的字段通過(guò)自己服務(wù)器的登錄接口傳給后臺(tái)，后臺(tái)再去調(diào)用各個(gè)平臺(tái)獲取用戶信息的接口并和自己服務(wù)器的賬戶體系綁定。

===========分享==========

一般我們分享都是采用文字+圖片+url鏈接，微信和QQ都比較簡(jiǎn)單，但是微博規(guī)定多媒體(url鏈接)與圖片不可以同時(shí)存在，下面會(huì)提到在這種情況下如何實(shí)現(xiàn)鏈接分享。
