在最前面闻鉴，還是先感謝開發(fā)過程中一下兩個帖子對自己的幫助茵乱，分享！Ｃ系骸瓶竭！
為了公司的安全，這個版本的微信信息我沒配置渠羞，不過斤贰，剛在網(wǎng)上找到個可以使用的，還是分享下次询，如下：
1.向微信注冊你的應(yīng)用程序信息
我們的App由我們的項目經(jīng)理搞定荧恍，具體我也不清楚
官方接入指南如下:
請到 開發(fā)者應(yīng)用登記頁面 進行登記，登記并選擇移動應(yīng)用進行設(shè)置后渗蟹，將獲得AppID块饺，可立即用于開發(fā)赞辩。但應(yīng)用登記完成后還需要提交審核，只有審核通過的應(yīng)用才能正式發(fā)布使用授艰。
2.下載微信終端SDK文件辨嗽，項目中導(dǎo)入lib,SDKExport兩個文件
下載iOS第二個
2.1導(dǎo)進去SDK后需要完善一些配置，要不會報錯
-
導(dǎo)入必要的庫
導(dǎo)入必要類庫 -
ARC和MRC配置淮腾，在后面添加-fno-objc-arc
ARC和MRC配置 -
bitCode和HTTPS配置糟需，iOS9后必須配置的
bitCode和HTTPS配置指導(dǎo)
3.上代碼，勝過千言萬語
