1.导入<MapKit/MapKit.h>

2.懒加载

@property (nonatomic, strong) CLGeocoder *geoC;
- (CLGeocoder *)geoC
{
    if (!_geoC) {
        _geoC = [[CLGeocoder alloc] init];
    }
    return _geoC;
}

3.将起点和终点, 传递给系统地图

- (void)beginNavWithBpl:(CLPlacemark *)beginP andEndP:(CLPlacemark *)endP
{
    //创建开始的地图项
    CLPlacemark *clpB = beginP;
    MKPlacemark *mkPB = [[MKPlacemark alloc] initWithPlacemark:clpB];
    MKMapItem *beginI = [[MKMapItem alloc] initWithPlacemark:mkPB];
    
    //创建结束的地图项
    CLPlacemark *clp = endP;
    MKPlacemark *mkP = [[MKPlacemark alloc] initWithPlacemark:clp];
    MKMapItem *endI = [[MKMapItem alloc] initWithPlacemark:mkP];
    
    //地图项数组
    NSArray *items = @[beginI,endI];
    //启动字典
    NSDictionary *dict = @{
                           //导航方式
                           MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeKey,
                           //地图类型
                           MKLaunchOptionsMapTypeKey:@(MKMapTypeHybrid),
                           //是否显示交通
                           MKLaunchOptionsShowsTrafficKey:@(YES)
                           
                           };
    [MKMapItem openMapsWithItems:items launchOptions:dict];
    
}

4.利用系统APP, 进行导航

- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
   [self.geoC geocodeAddressString:@"昆明" completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
        // 昆明地标
        CLPlacemark *kmP = [placemarks firstObject];
        [self.geoC geocodeAddressString:@"郑州" completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
            // 郑州地标
            CLPlacemark *zzP = [placemarks firstObject];
            [self beginNavWithBpl:kmP andEndP:zzP];
        }];
    }];

}
