iOS9 的那些坑

1.在Info.plist中添加NSAppTransportSecurity类型Dictionary。
2.在NSAppTransportSecurity下添加NSAllowsArbitraryLoads类型Boolean,值设为YES

用source code打开如下：

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

针对个别网站配置

1.子域名同样适用
NSIncludesSubdomains Boolean类型 YES
2.禁用ForwardSecrecy
NSExceptionRequiresForwardSecrecy Boolean类型 NO
3.允许签名过期 或者不匹配情况
NSTemporaryExceptionAllowsInsecureHTTPLoads Boolean类型 YES

用source code打开如下：

<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>baidu.com</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSTemporaryExceptionMinimumTLSVersion</key>
<string>TLSv1.1</string>
</dict>
</dict>
</dict>

iOS 9 分享适配

URL Scheme 用于应用程序的分享或者跳转到其他平台的授权，分享或者授权后再跳回来
在iOS 8 没有做限制，但是在iOS 9 需要将在外部调用的URL Scheme列为白名单才可以跳转
没做适配的情况下 会报错：
-canOpenURL: failed for URL: "mqq://" - error: "This app is not allowed to query for scheme mqq"
解决办法：在info.plist设置LSApplicationQueriesSchemes（数组），在里面添加用到的URL Scheme

用source code打开如下：

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

============================================
注：

 <!-- 集成微信、QQ、Qzone、腾讯微博授权对应的HTTP白名单-->
 <key>qq.com</key>
 <dict> 
 <key>NSIncludesSubdomains</key>
 <true/> 
 <key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key> 
 <true/>
 <key>NSThirdPartyExceptionRequiresForwardSecrecy</key> 
 <false/>
 </dict>
 <!-- 腾讯授权-->

============================================

另外 还要注意iOS 9 以后可能有些lable的内容是显示不全的！
