iOS 调用第三方地图进行导航

 //支持的地图
 {
    _model = model;
    //支持的地图
    NSMutableArray *maps = [NSMutableArray array];
    //苹果原生地图-苹果原生地图方法和其他不一样
    NSMutableDictionary *iosMapDic = [NSMutableDictionary dictionary];
    iosMapDic[@"title"] = @"苹果地图";
    [maps addObject:iosMapDic];
    //百度地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {
        NSMutableDictionary *baiduMapDic = [NSMutableDictionary dictionary];
        baiduMapDic[@"title"] = @"百度地图";
        NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%@,%@|name=%@&mode=driving&coord_type=gcj02",model.latitube,model.longitube,model.name] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        baiduMapDic[@"url"] = urlString;
        [maps addObject:baiduMapDic];
    }
    //高德地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
        NSMutableDictionary *gaodeMapDic = [NSMutableDictionary dictionary];
        gaodeMapDic[@"title"] = @"高德地图";
        NSString *urlString = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=%@&sid=BGVIS1&slat=&slon=&sname=&did=BGVIS2&dlat=%@&dlon=%@&dname=%@&dev=0&t=2",[[BDMethod bd_shareBDMethod] bd_getAppName],model.latitube,model.longitube,_model.name] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        gaodeMapDic[@"url"] = urlString;
        [maps addObject:gaodeMapDic];
    }
    //选择
    UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"选择地图" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    NSInteger index = maps.count;
    for (int i = 0; i < index; i++) {
        NSString * title = maps[i][@"title"];
        //苹果原生地图方法
        if (i == 0) {
            UIAlertAction * action = [UIAlertAction actionWithTitle:title style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
                [self navAppleMap];
            }];
            [alert addAction:action];
            continue;
        }
        UIAlertAction * action = [UIAlertAction actionWithTitle:title style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSString *urlString = maps[i][@"url"];
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
        }];
        [alert addAction:action];
    }
    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
    }];
    [alert addAction:cancelAction];
    [vc presentViewController:alert animated:YES completion:nil];
}

//苹果地图
- (void)navAppleMap
{
    //终点坐标
    CLLocationCoordinate2D loc = CLLocationCoordinate2DMake([_model.latitube doubleValue], [_model.longitube doubleValue]);
    //用户位置
    MKMapItem *currentLoc = [MKMapItem mapItemForCurrentLocation];
    //终点位置
    MKMapItem *toLocation = [[MKMapItem alloc]initWithPlacemark:[[MKPlacemark alloc]initWithCoordinate:loc addressDictionary:nil] ];
    NSArray *items = @[currentLoc,toLocation];
    //第一个
    NSDictionary *dic = @{
                          MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving,
                          MKLaunchOptionsMapTypeKey : @(MKMapTypeStandard),
                          MKLaunchOptionsShowsTrafficKey : @(YES)
                          };
    [MKMapItem openMapsWithItems:items launchOptions:dic];
}
