百度地图的简单使用
提示：我这里有使用到 storyboard
- 首先你需要导入百度地图的相关包，这些都可以在百度地图官方API里下载，然后就是在要展示百度地图的类里引入你需要的头文件，继承其相关 delegate 。
- 初始化百度地图和定位
_mapView = [[BMKMapView alloc]initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), CGRectGetHeight(self.view.bounds))];
_mapView.delegate = self;
[self.showMapView addSubview:_mapView];
_locService = [[BMKLocationService alloc]init];
_locService.delegate = self;
[_locService startUserLocationService];
- 进行相关设置（这里的这个 "icon_nav_start" 就是自己定义的当前位置大头针图片）
-(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
_locService.delegate = self;
}
- (void)viewDidAppear:(BOOL)animated{
BMKLocationViewDisplayParam *displayParam = [[BMKLocationViewDisplayParam alloc]init];
displayParam.isRotateAngleValid = true;//跟随态旋转角度是否生效
displayParam.isAccuracyCircleShow = false;//精度圈是否显示
displayParam.locationViewImgName= @"icon_nav_start";//定位图标名称
[_mapView updateLocationViewWithParam:displayParam];
}
-(void)viewWillDisappear:(BOOL)animated {
[_mapView viewWillDisappear];
_mapView.delegate = nil; // 不用时，置nil
_locService.delegate = nil;
}
- 定位回调
#pragma mark - 定位回调
//实现相关delegate 处理位置信息更新
//处理方向变更信息
- (void)didUpdateUserHeading:(BMKUserLocation *)userLocation
{
//[_mapView updateLocationData:userLocation];
}
//处理位置坐标更新
- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation
{
if(_coordinate.latitude==0){
NSLog(@"didUpdateUserLocation lat %f,long %f",userLocation.location.coordinate.latitude,userLocation.location.coordinate.longitude);
_coordinate.latitude = userLocation.location.coordinate.latitude;
_coordinate.longitude = userLocation.location.coordinate.longitude;
_mapView.showsUserLocation = YES;//显示定位图层
[_mapView updateLocationData:userLocation];
_mapView.centerCoordinate = _coordinate;
//发起反向地理编码检索
CLLocationCoordinate2D pt = _coordinate;
BMKReverseGeoCodeOption *reverseGeoCodeSearchOption = [[
BMKReverseGeoCodeOption alloc]init];
reverseGeoCodeSearchOption.reverseGeoPoint = pt;
BOOL flag = [_searcher reverseGeoCode:reverseGeoCodeSearchOption];
if(flag)
{
NSLog(@"反geo检索发送成功");
[_locService stopUserLocationService];
}
else
{
NSLog(@"反geo检索发送失败");
}
}
}
#pragma mark - 反向地理编码检索回调
-(void) onGetReverseGeoCodeResult:(BMKGeoCodeSearch *)searcher result:(BMKReverseGeoCodeResult *)result errorCode:(BMKSearchErrorCode)error{
if (error == BMK_SEARCH_NO_ERROR) {
NSString *cityName = result.addressDetail.city;
cityName=[cityName stringByReplacingOccurrencesOfString:@"市" withString:@""];
NSString *inputParam = [StringToJsonUtility initAddressParamData:cityName Status:@""];
// [_soap clearValues];
// [_soap setValue:inputParam forKey:@"addressParam"];
// [_soap requestURL:WebService_asmx soapAction:WebService_AddressService];
// _soapAgent = @"AddressService";
// NSString * headstr = [StringToJsonUtility initHeadParamData:_loginUser password:_password];
// [_soapClient getDataAPIResultWithURL:WebService_asmx
// headerParams:headstr
// params:inputParam
// htttpMethod:@"POST"
// withSOAPAction:WebService_AddressService
// withMethodName:@"AddressService"
// withParamKey:@"addressParam"
// withResultBlock:^(id result, BOOL isDictionary,id message) {
// //[weakSelf ];
// }];
}
else {
NSLog(@"抱歉，未找到结果");
}
}
这里对于这个反向地址编码回调里面的内容我有必要说明一下：由于项目需要根据当前位置去请求周围的其他大头针位置，所以这里其实是一个请求，用来去获取其他大头针位置，你可以选择忽略！
- 大头针以及气泡自定义
#pragma mark - 显示大头针
/**
*根据anntation生成对应的View
*@param mapView 地图View
*@param annotation 指定的标注
*@return 生成的标注View
*/
- (BMKAnnotationView *)mapView:(BMKMapView *)view viewForAnnotation:(id <BMKAnnotation>)annotation
{
if([annotation isKindOfClass:[BMKPinAnnotationView class]]){
BMKAnnotationView* annotationView = [view dequeueReusableAnnotationViewWithIdentifier:@"xidanMark"];
NSLog(@"用户位置图标！");
return annotationView;
}else{
// 生成重用标示identifier
NSString *AnnotationViewID = @"xidanMark";
// 检查是否有重用的缓存
BMKAnnotationView* annotationView = [view dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];
// 缓存没有命中，自己构造一个，一般首次添加annotation代码会运行到此处
if (annotationView == nil) {
annotationView = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];
((BMKPinAnnotationView*)annotationView).pinColor = BMKPinAnnotationColorRed;
// 设置重天上掉下的效果(annotation)
((BMKPinAnnotationView*)annotationView).animatesDrop = YES;
}
// 设置位置
annotationView.centerOffset = CGPointMake(0, -(annotationView.frame.size.height * 0.5));
annotationView.annotation = annotation;
// 单击弹出泡泡，弹出泡泡前提annotation必须实现title属性
annotationView.canShowCallout = NO;
// 设置是否可以拖拽
annotationView.draggable = NO;
// 设置大头针图标
annotationView.image=[UIImage imageNamed:@"siteGreen"];
return annotationView;
}
}
#pragma mark 选中大头针的时候，弹出POP画面
-(void)mapView:(BMKMapView *)mapView didSelectAnnotationView:(BMKAnnotationView *)view{
if([view isKindOfClass:[BMKPinAnnotationView class]]){
_popUpView.frame=CGRectMake(0,self.view.frame.size.height-220, SCREENWIDTH, 170);
for (int i=0; i<_annotationArray.count; i++)
{
if (view.annotation.coordinate.latitude ==((BMKPointAnnotation*)_annotationArray[i]).coordinate.latitude)
{//获取到当前的大头针 你可以执行一些操作
_address.text = [NSString stringWithFormat:@"%@", _array[i][@"Address"]];
_price.text = [NSString stringWithFormat:@"%.1f 元/度" ,[_array[i][@"Price"] floatValue]];
if([@"0" isEqualToString:[NSString stringWithFormat:@"%@", _array[i][@"DisCount"]]]){
_discount.text = [NSString stringWithFormat:@"无"];
}else{
_discount.text = [NSString stringWithFormat:@"%@", _array[i][@"DisCount"]];
}
_numForAll.text = [NSString stringWithFormat:@"%@ 台", _array[i][@"SumOfTotalPoint"]];
_numForFree.text = [NSString stringWithFormat:@"%@ 台", _array[i][@"FreeSumOfPoint"]];
//计算距离
BMKMapPoint point1 = BMKMapPointForCoordinate(_coordinate);
BMKMapPoint point2 = BMKMapPointForCoordinate(CLLocationCoordinate2DMake(view.annotation.coordinate.latitude, view.annotation.coordinate.longitude));
CLLocationDistance distance = BMKMetersBetweenMapPoints(point1,point2);
_distance.text = [NSString stringWithFormat:@"%.2f 公里",distance/1000];
_chargeSetId = _array[i][@"Id"];
}
}
_desCoordinate = [view.annotation coordinate];
CATransition *animation = [CATransition animation];
animation.duration = 0.5f;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
[self.view.layer addAnimation:animation forKey:@"animation"];
[self.view addSubview:_popUpView];
[self.view bringSubviewToFront:_popUpView];
}else{
NSLog(@"选中我的位置！");
}
}
#pragma mark 点击地图空白旳地方时候
-(void)mapView:(BMKMapView *)mapView onClickedMapBlank:(CLLocationCoordinate2D)coordinate{
CATransition *animation = [CATransition animation];
animation.duration = 0.5f;
animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
animation.fillMode = kCAGravityTopRight;
animation.type = kCATransitionFromTop;
[self.view.layer addAnimation:animation forKey:@"animation"];
[_popUpView removeFromSuperview];
[_selectSubView removeFromSuperview];
}
其中： _popUpView 就是自定义的气泡视图，下面的 _address 、_price 等都是视图中的子元素，这里使用的 storyboard 关联。_annotationArray 为从后台请求到的周围大头针数据。
-
气泡视图
storyboard自定义气泡视图
这里我为了图个方便就直接使用的 storyboard 自定义视图，实际中也可以通过代码实现。
以上就是我整个自定义百度地图的实现！
