试图获得与iOS项目集成的当前位置

Question

所以我试图将用户的当前位置与我的iOS项目集成 - 我使用第三部分代码构建出具有pinpoint的地图 - 我集成了这些框架：

#import <UIKit/UIKit.h> 
#import <CoreLocation/CoreLocation.h> 
#import <QuartzCore/QuartzCore.h> 
#import <MapKit/MapKit.h> 

这里是我的代码与精确定位 - 任何帮助将不胜感激：

#import "asyMap.h"

在你init方法，加入这一行

self.showsUserLocation = YES;
