社交分享:-canOpenURL: failed for URL: "weixin://app/*************/" - error: "This app is not allowed to query for scheme weixin"

升級到iOS9后，微信，QQ，微博等社交軟件的分享都失效了，控制台默默地打印了這條信息：

This app is not allowed to query for scheme xxx

 

這是因為iOS 9系統策略更新，限制了http協議的訪問，此外應用需要在“Info.plist”中將要使用的URL Schemes列為白名單，才可正常檢查其他應用是否安裝。

受此影響，當你的應用在iOS 9中需要使用微信SDK的相關能力（分享、收藏、支付、登錄等）時，需要在“Info.plist”里配置:
