打包CLLocationManager定位获取经纬度

封装CLLocationManager定位获取经纬度

创建调用方法

#import <Foundation/Foundation.h>

@interface RMMapLocation : NSObject
{
    void (^saveGpsCallBack)(double lattitude,double longitude);
}
+ (void)getGps:(void(^)(double lattitude,double longitude))block;
+ (void)stop;//停止定位

#import "RMMapLocation.h"

@interface RMMapLocation ()<CLLocationManagerDelegate>
@property (strong, nonatomic)CLLocationManager *locManager;

@end

@implementation RMMapLocation

+ (instancetype)sharedGpsManager
{
    static id mapLocation;

    }
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error

调用方法(如果只想定位一次调用stop方法即可)

[RMMapLocation getGps:^(double lattitude, double longitude) {
        RMLog(@"%f----%f",lattitude,longitude);
    }];
