1.基础创建及相关使用类
创建地图、当前位置对象、定位管理类
//初始化地图

由于iOS系统限制，需要在定位未开始之前或定位停止之后，修改该属性的值才会有效果。
*/

}
地图定位代理方法

#import <BaiduMapAPI_Utils/BMKGeometry.h>
#import <BaiduMapAPI_Base/BMKBaseComponent.h>
#import <BaiduMapAPI_Search/BMKSearchComponent.h>

//定位图层图标

[self.mapView updateUserLocationRepresentation:self.represent];
}
//其他地方有区别更新

}
} else {

}
7.逆编码
相关链接：https://blog.csdn.net/chongran9230/article/details/100804174
8.引入相关地图文件名和协议
文件名：
#import <AMapNaviKit/AMapNaviKit.h>
#import <AMapSearchKit/AMapSearchKit.h>
#import <AMapFoundationKit/AMapFoundationKit.h>
#import <AMapLocationKit/AMapLocationKit.h>
协议：
<MAMapViewDelegate, AMapSearchDelegate, AMapLocationManagerDelegate>
3.地图SDK导入工程及plist权限添加
百度地图相关SDK：地图、导航、定位、鹰眼
百度地图使用相关权限
高德地图相关SDK：地图、导航、定位、鹰眼
高德地图使用相关权限
判断手机App地图定位权限是否有打开：
举例：如果App定位权限不是“始终”，则提醒打开
- (void)jugdeIsOpenAlwaysLocation {
//如果用户选择的定位权限不是“始终”，则弹窗让用户修改权限
if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorizedAlways) {
UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"提示" message:@"定位权限请选择“始终”，否则服务无法使用！" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[self.navigationController popToRootViewControllerAnimated:YES];
}];
UIAlertAction * okAction = [UIAlertAction actionWithTitle:@"前往开启" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
}];
[alertController addAction:cancelAction];
[alertController addAction:okAction];
[self presentViewController:alertController animated:YES completion:nil];
return;
}
}
