iOS9 http 不能连接的解决办法

iOS9要求App内访问的网络必须使用HTTPS协议。原有的HTTP请求会报错，适配方法如下。

打开TARGETS-Build Phases， 添加New Run Script Phase，代码如下：

# Add exception for Debug builds
if [ "${CONFIGURATION}" == "Debug" ]
then
# Remove exception existing builds
/usr/libexec/PlistBuddy -c "Delete :NSAppTransportSecurity:NSAllowsArbitraryLoads" "${CONFIGURATION_BUILD_DIR}/${INFOPLIST_PATH}"
exitCode=$? #Supresses failure

/usr/libexec/PlistBuddy -c "Add :NSAppTransportSecurity:NSAllowsArbitraryLoads bool true" "${CONFIGURATION_BUILD_DIR}/${INFOPLIST_PATH}"
fi

其中"${CONFIGURATION}" == "Debug"的Debug替换为相应编译环境即可
