在 iOS 8 上编译会出现以下 log ：
Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.
经搜索得到解决方法如下：
1、修改info.plist：
新增key值为NSLocationWhenInUseUsageDescription 或 NSLocationAlwaysUsageDescription（这里，我将两个都加了进去），一定要设置内容，不然不能调用授权。（个别就是info.plist中还需要包含Supported interface orientations 这个Array字段。然后运行就解决了）。
2、修改代码：
在调用方法startUpdatingLocation的前面加上一句
1 if ([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {2 [locationManager requestWhenInUseAuthorization];3 }============================
3、博客原文修改方法：
