先倒入两个框架

显示除地图

self.view addSubview:_mapview];
    //显示指定位置
    //用地理位置的名称获取经纬度

        }
else

        }
    }];

实现地图的位置查询和交通搜索 这里时又新建了一个项目



- (void)viewDidLoad
{
    [super viewDidLoad];
    //添加地图视图，锁定显示定位范围，添加标记针头，
    //添加新功能LocalSearchquset初始化，添加寻找地方名，请求范围，初始化寻找，bing strat
// Do any additional setup after loading the view, typically from a nib.
    self.mapview =[[[MKMapView alloc]initWithFrame:self.view.bounds]autorelease];
self.view addSubview:_mapview];
     
    CLLocationCoordinate2D coordinate=CLLocationCoordinate2DMake(24.489084, 118.103338);
    //显示范围以经纬度做单位
    MKCoordinateSpan span=MKCoordinateSpanMake(0.08, 0.08);
    [self.mapview setRegion:MKCoordinateRegionMake(coordinate,span) animated:YES];
    //添加标记
    MKPointAnnotation *point=[[[MKPointAnnotation alloc]init]autorelease];
title= @"人才中心";
subtitle=@"欢迎来到美丽的小岛";
    point.coordinate=CLLocationCoordinate2DMake(24.489084, 118.103338);//标记经纬度
    [self.mapview setSelectedAnnotations:[NSArray arrayWithObject:point]];
     
    MKLocalSearchRequest *seachrequest=[[[MKLocalSearchRequest alloc]init]autorelease];
    seachrequest.naturalLanguageQuery=@"酒店";
region=MKCoordinateRegionMake(coordinate, span);
MKLocalSearch *locasearch=[[MKLocalSearch alloc]initWithRequest:seachrequest];
startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError
if(error)
        {
             
        }
else
        {
for(MKMapItem *mapitem in response.mapItems)
            {
                MKPointAnnotation *pointk=[[[MKPointAnnotation alloc]init]autorelease];
title=mapitem.name;
MKPlacemark *placemark=mapitem.placemark;
//获取经纬度
coordinate=placemark.location.coordinate;
subtitle=[placemark.addressDictionary objectForKey:@"Street"];
_mapview addAnnotation:pointk];
            }
        }
    }];
    //查询路线
    MKPlacemark *placmark=[[MKPlacemark alloc]initWithCoordinate:CLLocationCoordinate2DMake(24.446294, 118.073174) addressDictionary:nil];

}
