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