6:关于iOS11定位失效的问题解决方案
This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain both NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription keys with string values explaining to the user how the app uses this data
具体原因是苹果原来的永久定位权限已经下降为使用期间
需要新增如下两个权限，
NSLocationAlwaysAndWhenInUseUsageDescription 和 NSLocationWhenInUseUsageDescription
在plist文件中添加这两个就可以了。
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>允许访问位置</string>
