ios11 更新后定位失效问题适配

问题：一觉醒来，很多客户反映app不能定位了。查询相关资料后发现是定位权限API有更新。

解决方法：info.plist中同时添加NSLocationAlwaysAndWhenInUseUsageDeion和NSLocationWhenInUseUsageDeion。

原因：

/*

* Either the NSLocationAlwaysAndWhenInUseUsageDeion key or both the

* NSLocationAlwaysUsageDeion and NSLocationWhenInUseUsageDeion

* keys must be specified in your Info.plist; otherwise, this method will do

* nothing, as your app will be assumed not to support Always authorization.

*/

苹果现在增加了一项新的隐私保护功能 NSLocationAlwaysAndWhenInUseUsageDeion，并且原有的 NSLocationAlwaysUsageDeion 被降级为 NSLocationWhenInUseUsageDeion。
