ios简单的地图定位

0.配置info    添加 NSLocationAlwaysUsageDescription这个东东。

1.需要库CoreLocation.framework。

2.声明 #import <CoreLocation/CoreLocation.h>（注意加入CLLocationManagerDelegate代理）

3.代码实现

// 判断定位操作是否被允许

if([CLLocationManager locationServicesEnabled]) {

_locationManager = [[CLLocationManager alloc] init];

_locationManager.delegate = self;

_locationManager.desiredAccuracy = kCLLocationAccuracyBest;

}else {

//提示用户无法进行定位操作

}

if ([_locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {

[_locationManager requestAlwaysAuthorization];

}

//开始定位，不断调用其代理方法

[_locationManager startUpdatingLocation];

4.代理回调定位结果

- (void)locationManager:(CLLocationManager *)manager

didUpdateLocations:(NSArray *)locations

{

// 1.获取用户位置的对象

CLLocation *location = [locations lastObject];

CLLocationCoordinate2D coordinate = location.coordinate;

NSLog(@"纬度:%f 经度:%f", coordinate.latitude, coordinate.longitude);

strLongitude = [NSString stringWithFormat:@"%f",coordinate.longitude];

strLatitude = [NSString stringWithFormat:@"%f",coordinate.latitude];

// 2.停止定位

[manager stopUpdatingLocation];

}
