适配 ios 9

iOS 9适配系列教程：Bitcode（通俗解释：在线版安卓ART模式）

未来Watch应用须包含Bitcode，iOS不强制，但Xcode7默认会开启Bitcode。

如何适配？

方法一：更新library使包含Bitcode，否则会出现以下中的警告；

方法二：关闭Bitcode，方法见下图

OS 9 and OSX 10.11 require TLSv1.2 SSL for all hosts you plan to request data from unless you specify exception domains in your app's Info.plist file.
The syntax for the Info.plist configuration looks like this:

<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>yourserver.com</key>
<dict>
<!--Include to allow subdomains-->
<key>NSIncludesSubdomains</key>
<true/>
<!--Include to allow insecure HTTP requests-->
<key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
<true/>
<!--Include to specify minimum TLS version-->
<key>NSTemporaryExceptionMinimumTLSVersion</key>
<string>TLSv1.1</string>
</dict>
</dict>
</dict>

If your application (a third-party web browser, for instance) needs to connect to arbitrary hosts, you can configure it like this:

<key>NSAppTransportSecurity</key>
<dict>
<!--Connect to anything (this is probably BAD)-->
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
