1，再 build phases 中的 link binary with libraries 中导入 CoreLocation.framework 库

2，包含：#import <CoreLocation/CoreLocation.h>

3，特别需要注意的： iPhone 机需要链接网络，否则获取的 placemarks is null

4，在info.plist 中添加

<key>NSLocationWhenInUseUsageDescription</key>  <string>此App需要您的同意才能访问您的位置</string>

@interface LocationTest : NSObject<CLLocationManagerDelegate>{    CLLocationDegrees lati;    CLLocationDegrees longti;}@property(nonatomic,strong)CLLocationManager *locationManager;-(void)InitLocation;
