在iOS中, 地图开发经常会用到的三个框架, 一个是苹果系统自带的MapKit框架, 另外两个, 一个是百度地图BMKMapView, 另一个是高德地图MAMapView.
使用原生地图
使用原生地图
MapKit:地图框架显示地图
CoreLocation:定位框架, 没有地图时也可以使用定位.
#import
@interface SignShakeViewController ()
{
CLLocationManager *_locationManager;
NSString *lat;
NSString *lon;
NSString *name;
}
初始化定位管理器
#pragma mark 初始化定位管理器
- (void)initializeLocationService {
BOOL isEnable = [CLLocationManager locationServicesEnabled];
CGFloat version = [[UIDevice currentDevice].systemVersion doubleValue];//float
if(isEnable) {
if(!_locationManager){
// 初始化定位管理器
_locationManager = [[CLLocationManager alloc] init];
// 设置代理
_locationManager.delegate = self;
// 设置定位精确度到米
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
// 设置过滤器为无
_locationManager.distanceFilter = kCLDistanceFilterNone;
if(version > 8.0f){
// 请求定位服务
// 取得定位权限,有两个方法,取决于你的定位使用情况
// 一个是requestAlwaysAuthorization,一个是requestWhenInUseAuthorization
// iOS8对定位进行了一些修改，其中包括定位授权的方法,CLLocationManager增加了下面的两个方法
// 在Info.plist文件中添加如下配置：
// NSLocationAlwaysUsageDescription Always
// NSLocationWhenInUseUsageDescription InUse
[_locationManager requestAlwaysAuthorization];//这句话ios8以上版本使用。
}
[_locationManager startUpdatingLocation];
}
}
else{
NSLog(@"当前设备定位功能未开启!,建议您到手机系统的[设置]->[隐私]->[定位服务]中打开定位服务");
return;
}
}
实现CLLocationManagerDelegate的代理方法
#pragma mark - 实现CLLocationManagerDelegate的代理方法
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
// 取出第一个位置
CLLocation *location = [locations lastObject];
// 位置坐标
CLLocationCoordinate2D coordinate = location.coordinate;
NSLog(@"经度：%f,纬度：%f,海拔：%f,航向：%f,行走速度：%f",coordinate.longitude,coordinate.latitude,location.altitude,location.course,location.speed);
lat = [NSString stringWithFormat:@"%f",coordinate.latitude];
lon = [NSString stringWithFormat:@"%f",coordinate.longitude];
// 反地理编码
CLGeocoder *_geocoder;
_geocoder = [[CLGeocoder alloc]init];
[_geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
CLPlacemark *placemark = [placemarks firstObject];
// NSLog(@"详细信息:%@",placemark.addressDictionary);
// 1.CountryCode CN
// 2.Country 中国
// 3.State 云南省
// 4.City 昆明市
// 5.SubLocality 五华区
// 6.Street 学府路183号
// 7.Thoroughfare 学府路
// 8.SubThoroughfare 183号
// 9.Name 中国云南省昆明市五华区莲华街道学府路183号
NSDictionary *addressDictionary = placemark.addressDictionary;
name = [addressDictionary objectForKey:@"Name"];
}];
// 如果不需要实时定位,使用完关闭定位服务
[manager stopUpdatingLocation];
}
定位失败,回调此方法
// 定位失败,回调此方法
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
NSLog(@"error :%@",[error localizedDescription]);
if ([error code]==kCLErrorDenied) {
NSLog(@"访问被拒绝");
}
if ([error code]==kCLErrorLocationUnknown) {
NSLog(@"无法获取位置信息");
}
}
使用高德地图API
