iOS 微信登錄、分享的實(shí)現(xiàn)

微信大大的一些用于登錄、分享和支付的硬性前提要求:

  • 不論是接入微信的登錄、支付還是分享都必須要提前進(jìn)行 應(yīng)用審核。
  • 只有審核完成后才能有AppID和App Secret。
  • 并且如果需要獲取更高的權(quán)限，必須要進(jìn)行申請審核 (還要交錢)。
  • 微信開發(fā)者平臺(tái) 提交的應(yīng)用中的審核官網(wǎng)地址可填如下: http://www.apple.com/cn/itunes/ 公司官網(wǎng)地址即可。

微信登錄、分享和支付的SDK，包含如下文件:

接入微信給工程添加相應(yīng)的配置

1.開發(fā)者需要鏈接下面的系統(tǒng)庫: Link Frameworks and Libraries

iOS-微信-linkFramework.png

2.在工程文件中選擇 Taeget-->Build Setting，在"Other Linker Flags"中加入"-Objc -all_load"。 在 Search Paths 中添加 libWeChatSDK.a ，WXApi.h，WXApiObject.h，文件所在位置。

3.在Xcode中，選擇你的工程設(shè)置項(xiàng)，選中 TARGETS-->info-->URL type “添加“ URL scheme”為你所注冊的應(yīng)用程序id（應(yīng)用程序AppID在微信開發(fā)者平臺(tái)創(chuàng)建移動(dòng)應(yīng)用）

iOS-微信SDK-URLScheme.png

4.在Xcode中，選擇你的工程設(shè)置項(xiàng)，選中“TARGETS”一欄，在“info”標(biāo)簽欄的 LSApplicationQueriesSchemes 添加 weixin和wechat兩個(gè)白名單

iOS-微信SDk-白名單添加.png

5.允許網(wǎng)絡(luò)傳輸: iOS9中新增App Transport Security（簡稱ATS）特性, 主要使到原來請求的時(shí)候用到的HTTP，都轉(zhuǎn)向TLS1.2協(xié)議進(jìn)行傳輸。這也意味著所有的HTTP協(xié)議都強(qiáng)制使用了HTTPS協(xié)議進(jìn)行傳輸。需要在Info.plist新增一段用于控制ATS的配置：

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

目前移動(dòng)應(yīng)用上德微信登錄只提供 原生的登錄方式，需要用戶 安裝微信客戶端 才能配合使用。

對(duì)于iOS應(yīng)用,考慮到iOS應(yīng)用商店審核指南中的相關(guān)規(guī)定，建議開發(fā)者接入微信登錄時(shí)，先檢測用戶手機(jī)是否已經(jīng)安裝

微信客戶端(使用sdk中的isWXAppInstall函數(shù)),對(duì)于未安裝的用戶隱藏微信 登錄按鈕，只提供其他登錄方式。</font>
