iOS开发--使用友盟快速分享与第三方登录注意事项

官方说的比较详细，但是就是有些重复，而且有很多坑

坑1、集成后，打开app发现一堆问题（如下）

解决办法：

在info.plist中加入安全域名白名单(右键info.plist用source code打开)

原因：

1. HTTP传输安全
   发布的iOS9系统上围绕用户数据的安全性和体验新增了一些安全特性
   以iOS9 SDK编译的工程会默认以SSL安全协议进行网络传输，即HTTPS

在info.plist的NSAppTransportSecurity下新增NSAllowsArbitraryLoads并设置为YES，指定所有HTTP连接都可正常请求 http://dev.umeng.com/social/ios/ios9

// 推出iOS9之后，看到http请求就应该知道+这个
<key>NSAppTransportSecurity</key>
<dict> 
<key>NSAllowsArbitraryLoads</key>
 <true/>
</dict>

坑2、集成第三方登录后

打开app，用第三方登录，发现没有sso授权页面，或打开QQ失败、微信失败、微博失败等

解决办法：

info.plist增加：

原因：

在iOS9下就需要增加一个可跳转的白名单，指定对应跳转App的URL Scheme，否则将在第三方平台判断是否跳转时用到的canOpenURL时返回NO，进而只进行webview授权或授权/分享失败。
