上篇开启百度之旅 2
一 补充大头针和气泡常用的方法
1.1 初始化大头针给大头针标题
pointAnnotation = [[BMKPointAnnotation alloc] init];;
pointAnnotation.title = @“今天天气不错“;
1.2 点击大头针方法
- (void)mapView:(BMKMapView *)mapView didSelectAnnotationView:(BMKAnnotationView *)view {
NSLog(@"点击大头针");
}
1.3 点击气泡方法
- (void)mapView:(BMKMapView *)mapView annotationViewForBubble:(BMKPointAnnotation *)view{
NSLog(@"点击气泡");
}
二 定位到当前位置 地图画线（公交划线为例）
2.1代理<BMKMapViewDelegate, BMKRouteSearchDelegate,BMKLocationServiceDelegate>
2.2 导入头文件
#import <BaiduMapAPI_Map/BMKMapView.h>//只引入所需的单个头文件
#######import <BaiduMapAPI_Map/BMKMapComponent.h>
#######import <BaiduMapAPI_Search/BMKSearchComponent.h>
#######import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的头文件
#######import "UIImage+Rotate.h"(在百度地图Demo中找到拖到自己的工程中)
#######import "RouteAnnotation.h"(在百度地图Demo中找到拖到自己的工程中)
2.3 设置
//需要注意把.m文件改成.mm文件
#define MYBUNDLE_NAME @ "mapapi.bundle"
#define MYBUNDLE_PATH [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: MYBUNDLE_NAME]
#define MYBUNDLE [NSBundle bundleWithPath: MYBUNDLE_PATH]
#define BMKSPAN 0.02
2.4
{
int _type; ///<0:起点 1：终点 2：公交 3：地铁 4:驾乘 5:途经点
int _degree;
BMKRouteSearch* _routesearch;
BMKLocationService* _locService;
}
@property (nonatomic) int type;
@property (nonatomic) int degree;
@property (strong, nonatomic) IBOutlet BMKMapView *mapView;
@property (nonatomic,assign) CLLocationCoordinate2D coor;

if( ([[[UIDevice currentDevice] systemVersion] doubleValue]>=7.0))
{
self.navigationController.navigationBar.translucent = NO;
}
_mapView = [[BMKMapView alloc]initWithFrame:CGRectMake(0, 0, WIDTH,HEIGHT)];
_mapView.delegate = self;
//初始化BMKRouteSearch

//初始化BMKLocationService(定位)
_locService = [[BMKLocationService alloc]init];

[_locService startUserLocationService];
_mapView.showsUserLocation = YES;//显示定位图层
_mapView.showsUserLocation = NO;
_mapView.userTrackingMode = BMKUserTrackingModeNone;
_mapView.showsUserLocation = YES;
[self.view addSubview:_mapView];
2.5
-(void)viewWillAppear:(BOOL)animated {
[_mapView viewWillAppear];
_mapView.delegate = self; // 此处记得不用的时候需要置nil，否则影响内存的释放
_routesearch.delegate = self; // 此处记得不用的时候需要置nil，否则影响内存的释放
}
-(void)viewWillDisappear:(BOOL)animated {
[_mapView viewWillDisappear];
_mapView.delegate = nil; // 不用时，置nil

}
- (void)dealloc {

}

}

三 导航（调用百度客户端，没有客户端调取网页版）
3.1导航配置
