友盟分享是碰到微信未能安装等错误

碰到以上情况有两种可能，一种是https和http传输协议的问题，还有一个就是应用跳转的问题，友盟的官方文档上写的很清楚，我就直接复制过来了。

1.  HTTP传输安全

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，如果依然使用HTTP协议请求网络会报系统异常并中断请求。目前可用如下两种方式保持用HTTP进行网络连接：

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

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>log.umsns.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
        </dict>
        <key>sns.whalecloud.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
        </dict>

        <!-- 集成新浪微博对应的HTTP白名单-->

            <false/>

            <false/>
        </dict>

            <key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
            <false/>

        <!-- 人人授权-->

        <!-- 集成Facebook授权对应的HTTP白名单-->
        <key>facebook.com</key>
        <dict>

            <false/>
        </dict>

            <false/>
        </dict>
        <key>akamaihd.net</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>

        <!-- Facebook授权-->

        <!-- 集成Twitter授权对应的HTTP白名单-->

            <true/>                
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
        <!-- Twitter授权-->
    </dict>
</dict>

注：以上部分平台官方未给出相应白名单，由技术人员测试各个平台所收集而来，如果有所遗漏，请自行加入并向客服说明，我们会进一步补充名单。

B、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

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

2.  应用跳转（SSO等）

如果你的应用使用了如SSO授权登录或跳转分享功能，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。
同样在info.plist增加：

<key>LSApplicationQueriesSchemes</key>
<array>
    <!-- 微信 URL Scheme 白名单-->
    <string>wechat</string>
    <string>weixin</string>

    <!-- 新浪微博 URL Scheme 白名单-->
    <string>sinaweibohd</string>
    <string>sinaweibo</string>
    <string>sinaweibosso</string>
    <string>weibosdk</string>
    <string>weibosdk2.5</string>

    <!-- QQ、Qzone URL Scheme 白名单-->
    <string>mqqapi</string>
    <string>mqq</string>
    <string>mqqOpensdkSSoLogin</string>
    <string>mqqconnect</string>
    <string>mqqopensdkdataline</string>
    <string>mqqopensdkgrouptribeshare</string>
    <string>mqqopensdkfriend</string>
    <string>mqqopensdkapi</string>
    <string>mqqopensdkapiV2</string>
    <string>mqqopensdkapiV3</string>
    <string>mqzoneopensdk</string>
    <string>wtloginmqq</string>
    <string>wtloginmqq2</string>
    <string>mqqwpa</string>
    <string>mqzone</string>
    <string>mqzonev2</string>
    <string>mqzoneshare</string>
    <string>wtloginqzone</string>
    <string>mqzonewx</string>
    <string>mqzoneopensdkapiV2</string>
    <string>mqzoneopensdkapi19</string>
    <string>mqzoneopensdkapi</string>
    <string>mqqbrowser</string>
    <string>mttbrowser</string>

    <!-- 支付宝 URL Scheme 白名单-->
    <string>alipay</string>
    <string>alipayshare</string>


    <!-- 人人 URL Scheme 白名单-->
    <string>renrenios</string>
    <string>renrenapi</string>
    <string>renren</string>
    <string>renreniphone</string>

    <!-- 来往 URL Scheme 白名单-->
    <string>laiwangsso</string>

    <!-- 易信 URL Scheme 白名单-->
    <string>yixin</string>
    <string>yixinopenapi</string>

    <!-- instagram URL Scheme 白名单-->
    <string>instagram</string>

    <!-- whatsapp URL Scheme 白名单-->
    <string>whatsapp</string>

    <!-- line URL Scheme 白名单-->
    <string>line</string>

    <!-- Facebook URL Scheme 白名单-->
    <string>fbapi</string>
    <string>fb-messenger-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>

3.  应用瘦身（App Thining）

iOS9 SDK新增了对App瘦身的功能，详情见App Thining。目前各个第三方平台正在进行App thining的支持，所以为了正常使用第三方SDK及分享SDK，需要在Build Setting中将Enable bitcode关闭,或设置编译标识ENABLE_BITCODE=NO。
注：bitcode仅在Xcode7以上显示并默认开启。
