目录 需求 设计 代码实现 新建CLLocation 分类方法 调用示例 结论 需求 在地图导航时,始终保持当前路段竖直超前。 设计 因地图暴露的方法中只有设置地图相对于正北的方向角的方法。 代码实现 新建CLLocation 分类方法 #import <CoreLocation/CoreLocation.h> + (double)ca_getCompassAngleFromCoor1:( toRadius:lat1]; double φ2 = [CLLocation toRadius:lat2]; double Δλ = [CLLocation toRadius:(long2 * cos(Δλ); double y = sin(Δλ) * cos(φ2); double θ = atan2(y, x); double bearing = [CLLocation ; } + (double)toRadius:(double)degree { return degree * M_PI / 180.0; } 调用示例 double bearing = [CLLocation
在没找到该头文件前我本来是想放弃百度地图的这个方法而使用原生的方法的,原生的方法: CLLocation *location1 = [[CLLocation alloc] initWithLatitude :userLocation.location.coordinate.latitude longitude:userLocation.location.coordinate.longitude]; CLLocation *location2 = [[CLLocation alloc] initWithLatitude:model.latitude longitude:model.longitude] ; CLLocationDistance

iPhone SDK提供了三个类来管理位置信息:CLLocation CLLocationManager 和 CLLHeading(不常用)。 1、CLLocation CLLocation类代表一个位置信息,其中还包括了方向和速度。比如我在长安街188号以5公里/小时的速度往西走。 它的属性和方法有: @property CLLocation *location; //位置 @property id<CLLocationManagerDelegate> delegate; @property 这个类包含了多个属性:手机的位置(类型为CLLocation)、位置文字信息(类型为NSString)等。 MKPlacemark保存了位置(经纬度)和地址之间的映射。 设置经纬度 CLLocation *loc = [[CLLocation alloc]initWithLatitude:self.latitude longitude:self.longitude
对象 在startUpdatingLocation 代理方法中可以得到用户的坐标信息 // 1.获取最后一次的位置 CLLocation *location = [locations lastObject */ /* 可以设置模拟器模拟速度 bicycle ride 骑车移动 run 跑动 freeway drive 高速公路驾车 */ CLLocation *)location; // 北京:39.6 116.39 // 广州:23.08 113.15 CLLocation *BeiJing = [[CLLocation alloc ] initWithLatitude:39.6 longitude:116.39]; CLLocation *GuangZhou = [[CLLocation alloc] initWithLatitude CLLocation用来表示某个位置的地理信息,比如经纬度、海拔等等 // 属性 location.coordinate; 坐标, 包含经纬度 location.altitude;
位置对象介绍 CLLocation用来表示某个位置的地理信息,比如经纬度、海拔等等,创建一个 CLLocation对象只需要两个参数:纬度和经度 属性: (1)2D位置坐标,经纬度 @property *location1 = [[CLLocation alloc] initWithLatitude:40.06 longitude:116.39]; CLLocation *location2 = [ *> *)locations{ //CLLocation 位置对象 --> 经纬度 //CLLocationCoordinate2D coordinate 经纬度 //获取最后一次位置信息 CLLocation *location = locations.lastObject; //输出纬度和经度 NSLog(@"latitude: %f,longitude: % 创建 CLLocation对象,输入经纬度信息 CLLocation *location = [[CLLocation alloc] initWithLatitude:[self.latitudeTF.text
(WGS-84),或者叫GPS坐标 func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation self.locationManager.delegate = nil // 停止定位 self.locationManager.stopUpdatingLocation() } 三、CLLocation -> CLLocationDistance 四、逆地址解析 我们使用CLGeocoder实现逆地址解析,而且非常简单,如下 func reverseGeocodeLocation(location:CLLocation 就会有问题,举例子来说明: func reverseGeocodeLocation(location:CLLocation){ 假设lacation参数是通过didUpdateLocations } } case2:如果此时我从新创建一个CLLocation,此时在iOS9上是没有问题的,但在其他iOS系统上,解析出来就会有很多误差,如下代码 let loc = CLLocation
31 } 32 } 33 func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation ]) { 34 locationManager.stopUpdatingLocation() 35 36 let location:CLLocation = locations[0] 37 let
那么 CLLocation 对象又是什么呢? *> *)locations { CLLocation * location = [locations lastObject]; /* CLLocation )locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations { CLLocation * location = [locations lastObject]; NSString * locationInfo = nil; NSInteger "; CLLocation * location = [[CLLocation alloc] initWithLatitude:[_clLatitude.text doubleValue] longitude
本期内容: CLLocationManager申请定位权限 CLLocationManager获取用户定位 CLLocation详细使用,定位数据处理 GPX虚拟定位文件的使用以及模拟器定位使用 --- 具体实现如下: // 代理方法,更新位置 - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{ // locations是一个数组提供了一连串的用户定位,所以在这里我们只取最后一个(当前最后的定位) CLLocation * newLocation CLLocation详细使用,定位数据处理 在上面我们看到了一个类:CLLocation。和CLLocationManager很像是吧? 官方有话说:CLLocation对象包含设备的地理位置和高度,以及指示这些测量值的准确性和收集时间的值。在iOS中,位置对象还包含航向信息,即设备移动的速度和方向。 那我们如何来获得这些信息呢?
(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{ for(CLLocation *loc in locations){ //CLLocation 就是一次经纬度 , 方向 海拔 等信息 //loc.coordinate就是取的经纬度
CoreLocation class LocationManager: NSObject { typealias locationCallBack = (_ curLocation:CLLocation //当前坐标 var curLocation: CLLocation? CLLocationManagerDelegate { func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation
