1.2 使用示例
1.2.1 locationManager初始化
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
self.locationManager.distanceFilter = 1000.0f;
[self.locationManager startUpdatingLocation];
1.3.2 [endif]CLLocationManagerDelegate回调处理
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
#pragma mark - CLLocationManagerDelegate 委托处理
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray*)locations
{
_locationArray= locations;
if (!_locationArray) {
return;
}
CLLocation * location = [locations lastObject];
[manager stopUpdatingLocation];
// 添加一个PointAnnotation
//缩放级别设置
BMKCoordinateRegion viewRegion = BMKCoordinateRegionMakeWithDistance(location.coordinate, 200, 200);
BMKCoordinateRegion adjustRegion = [_bMapView regionThatFits: viewRegion];
adjustRegion.center.latitude += adjustRegion.span.latitudeDelta - viewRegion.span.latitudeDelta;
adjustRegion.center.longitude += adjustRegion.span.longitudeDelta - viewRegion.span.longitudeDelta;
BMKPointAnnotation* annotation = [[BMKPointAnnotation alloc] init];
annotation.coordinate = adjustRegion.center;
annotation.title = @"I'm Here";
//添加标注点
[_bMapView addAnnotation: annotation];
//设置地图中心的地理位置
[_bMapView setRegion: adjustRegion animated: YES];
[_annotationMArray addObject: annotation];
LOGDEBUG([NSString stringWithFormat: @"GetLocation: Lat:%f, Long:%f", location.coordinate.latitude, location.coordinate.longitude]);
}
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus: (CLAuthorizationStatus)status
{
switch(status) {
case kCLAuthorizationStatusNotDetermined:
LOGDEBUG(@"Request Location Authorization");
[manager requestWhenInUseAuthorization];
break;
default:
break;
}
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError: (NSError*)error
{
LOGDEBUG([NSString stringWithFormat: @"Get Location Fail: %@", error.userInfo]);
}
1.3.3 IOS 8.0后新增授权提示处理
1、在locationManager对象调用startUpdatingLocation方法前,需调用授权请求方法,或者实现didChangeAuthorizationStatus回调,对于未授权情况发起授权请求。主动调用requestWhenInUseAuthorization方法:
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0
// iPhone OS SDK 0.0 以后版本的处理
[self.locationManager requestWhenInUseAuthorization];
#else
// iPhone OS SDK 8.0 之前版本的处理
#endif
[self.locationManager startUpdatingLocation];
实现didChangeAuthorizationStatus回调,对于未授权情况调用requestWhenInUseAuthorization方法:
- (void) locationManager: (CLLocationManager*)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
switch (status) {
case kCLAuthorizationStatusNotDetermined:
LOGDEBUG(@"Request Location Authorization");
[manager requestWhenInUseAuthorization];
break;
default:
break;
}
}
2、在info.plist文件中增加至少一个授权Alert框的提示文本,可为空,建议将NSLocationWhenInUseUsageDescription、NSLocationAlwaysUsageDescription两个节点都配置上:

3 基于百度地图开发
开放平台:百度地图foriOS使用相关
http://blog.csdn.net/ysy441088327/article/details/8174276
3.1 类库引入
3.1.1 引入头文件
首先将百度MapAPI提供的头文件和静态库(.a)文件拷贝到您的工程目录下,在Xcode中添加新的文件Group,引入百度MapAPI提供的头文件(请使用Xcode 4.X以上平台)。
在您需要使用百度MapAPI的文件中添加以下代码
#import "BMapKit.h"
3.1.2 引入静态库文件
百度地图SDK提供了模拟器和真机两中环境所使用的静态库文件,分别存放在libs/Release-iphonesimulator和libs/Release-iphoneos文件夹下。有三种方式可以引入静态库文件:
第一种方式:直接将对应平台的.a文件拖拽至Xcode工程左侧的Groups&Files中,缺点是每次在真机和模拟器编译时都需要重新添加.a文件;
第二种方式:使用lipo命令将设备和模拟器的.a合并成一个通用的.a文件,将合并后的通用.a文件拖拽至工程中即可,具体命令如下:
lipo -create Release-iphoneos/libbaidumapapi.aRelease-iphonesimulator/libbaidumapapi.a -output libbaidumapapi.a
第三种方式:
1.将API的libs文件夹拷贝到您的Application工程跟目录下
2.在Xcode的Project -> Edit Active Target -> Build -> Linking -> Other Linker Flags中添加-ObjC
3.设置静态库的链接路径,在Xcode的Project -> Edit Active Target -> Build -> Search Path -> Library Search Paths中添加您的静态库目录,比如"$(SRCROOT)/../libs/Release$(EFFECTIVE_PLATFORM_NAME)",$(SRCROOT)宏代表您的工程文件目录,$(EFFECTIVE_PLATFORM_NAME)宏代表当前配置是OS还是simulator
注:静态库中采用ObjectC++实现,因此需要您保证您工程中至少有一个.mm后缀的源文件(您可以将任意一个.m后缀的文件改名为.mm),或者在工程属性中指定编译方式,即将Xcode的Project -> Edit Active Target -> Build -> GCC4.2 - Language -> Compile Sources As设置为"Objective-C++"
3.1.3 引入系统framework
百度地图SDK中提供了定位功能和动画效果,v2.0.0版本开始使用OpenGL渲染,因此您需要在您的Xcode工程中引入CoreLocation.framework和QuartzCore.framework、OpenGLES.framework、SystemConfiguration.framework、CoreGraphics.framework、Security.framework。 添加方式:右键点击Xcode工程左侧的Frameworks文件夹,add->Existing Frameworks,在弹出窗口中选中这几个framework,点击add即可。
3.1.4 引入mapapi.bundle资源文件
mapapi.bundle中存储了定位、默认大头针标注View及路线关键点的资源图片,还存储了矢量地图绘制必需的资源文件。如果您不需要使用内置的图片显示功能,则可以删除bundle文件中的image文件夹。您也可以根据具体需求任意替换或删除该bundle中image文件夹的图片文件。 添加方式:将mapapi.bundle拷贝到您的工程目录,直接将该bundle文件托拽至Xcode工程左侧的Groups&Files中即可。若您需要替换定位、指南针的图标,请保留原文件名称,否则不显示替换的新图片,默认大头针标注与路线关键点的新图片名称可自定义名称。
SDK
资源文件里存放的有:
3.1.5 其他建议
进行一系列的引入后,还需要注意以下两个细节,否则编译和运行时都会出错:
1:让XCode 处于 Objective - C++ 混编模式进行编译: 最简单方法就是:随便更改工程文件中的某一个,将.m更改为.mm .
2:由于静态库里面包含类别条目(第四点),所以需要让工程支持类别的编译: Project->Build Settings->Other Linker Flags 添加值: -all_load
3:关于 setPaopaoView 警告 临时解决方案如下: 在 Other Linker Flags新增一个 -w
4:建议合并静态库
3.2 api使用
3.2.1 反地理编码获取省市地理位置数据
http://my.oschina.net/u/1025290/blog/305749
要做百度的逆地理编码功能,肯定是要先启动百度服务了,这些就不再扯了。
//初始化地理编码类 注意:必须初始化地理编码类
BMKGeoCodeSearch *_geoCodeSearch = [[BMKGeoCodeSearch alloc] init];
_geoCodeSearch.delegate = self;
//初始化逆地理编码类
BMKReverseGeoCodeOption *reverseGeoCodeOption = [[BMKReverseGeoCodeOption alloc] init];
//需要逆地理编码的坐标位置
reverseGeoCodeOption.reverseGeoPoint = cllocation.coordinate;
[_geoCodeSearch reverseGeoCode: reverseGeoCodeOption];
这个是初始化的逆地理编码的类 ,其中reverseGeoPoint是需要做逆地理编码的poi坐标点,然后执行reverseGeoCode这个方法,根据地理坐标去获取地理位置信息。
逆地理编码的返回结果会再这个方法中返回,也就是个监听方法。
/**
*返回反地理编码搜索结果
*@param searcher 搜索对象
*@param result 搜索结果
*@param error 错误号,@see BMKSearchErrorCode
*/
- (void)onGetReverseGeoCodeResult:(BMKGeoCodeSearch *)searcher result:(BMKReverseGeoCodeResult *)result errorCode:(BMKSearchErrorCode)error
{
//BMKReverseGeoCodeResult是编码的结果,包括地理位置,道路名称,uid,城市名等信息
}
返回结果就是BMKReverseGeoCodeResult中得属性值,具体属性值 大家点击类里面去看,这个我就不多说了,好了,最简单的逆地理编码功能。
注意:逆地理编码监听方法不调用请查看百度key是否正确有效,是否授权成功。
当多类中使用地理编码功能时,建议将这些功能创建公用管理类,只需单利初始化,在监听方法中接收地理位置信息就可以了!
3.2.2 自定义标注图标
在地图上定制标注替代大头钉,可以将文字图片所有能加到view中的,都可以以大头钉的形式显示出来,需要将view转换为image主要代码,最重要的是知道这个原理,然后实现起来就很简单:
- (BMKAnnotationView *)mapView:(BMKMapView *)view viewForAnnotation:(id )annotation
在这个委托中实现如下代码:
UIView *viewForImage = [[UIView alloc] initWithFrame: CGRectMake(0, 0, 132, 64)];
UIImageView *imageview = [[UIImageView alloc] initWithFrame: CGRectMake(0, 0, 32, 64)];
[imageview setImage: [UIImage imageNamed: @"车位置.png"]];
[viewForImage addSubview: imageview];
UILabel *label=[[UILabel alloc] initWithFrame: CGRectMake(32, 0, 100, 64)];
label.text=@"陈双超";
label.backgroundColor = [UIColor clearColor];
[viewForImage addSubview: label];
annotationView.image = [self getImageFromView: viewForImage];
-(UIImage *)getImageFromView:(UIView *)view
{
UIGraphicsBeginImageContext(view.bounds.size);
[view.layer renderInContext: UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
3.2.3 显示比例尺
[self.mapView setShowMapScaleBar: YES];
3.2.4 设置缩放比例
BMKMapView.zoomLevel,不过要注意,设置完中心点之后再设置才有效!!!示例代码:
//设置地图中心的地理位置
[_mapView setCenterCoordinate: coordinate];
[_mapView setZoomLevel: 9.0];
3.2.5 微调与设置中心点
//设置中心点
-(BMKCoordinateRegion)setCenterRegionWithCoordinate:(CLLocationCoordinate2D) coordinate
{
NSLog(@"MyLat:%f, Lon:%f",coordinate.latitude,coordinate.longitude);
//缩放级别设置
BMKCoordinateRegion viewRegion = BMKCoordinateRegionMakeWithDistance(coordinate, AQ_Map_SearchSpan, AQ_Map_SearchSpan * self.mapView.frame.size.height / self.mapView.frame.size.width);
BMKCoordinateRegion adjustRegion = [_mapView regionThatFits:viewRegion];
// adjustRegion.center.latitude += adjustRegion.span.latitudeDelta -viewRegion.span.latitudeDelta;
// adjustRegion.center.longitude += adjustRegion.span.longitudeDelta -viewRegion.span.longitudeDelta;
//设置地图中心的地理位置
// if (!_isSetMapSpan) {
[_mapView setRegion: viewRegion animated: YES];
// _isSetMapSpan = true;
// }
// else [self.mapView setCenterCoordinate:adjustRegion.centeranimated:YES];
return adjustRegion;
}
3.2.6 添加标注点
BMKPointAnnotation* annotation = [[BMKPointAnnotation alloc]init];
annotation.coordinate = CLLocationCoordinate2DMake(cObj.latitude, cObj.longitude);
annotation.title = cObj.cityName;
//添加标注点
[_mapView addAnnotation: annotation];
3.2.7 更新标注点
-(void) updateBMKPointAnnotationsWithCityInfoArray
{
NSArray * array = [self getCityInfoArrayInDefaultSpan];
if (array && [array count] > 0) {
BMKPointAnnotation *pointAn;
NSMutableArray * _preDeleteMArray = [[NSMutableArray alloc] init];
BOOL needDelete = TRUE;
//查询需要移除的标注点
NSArray * tmpArray = [_pointAnnotationMArray copy];
for (BMKPointAnnotation * ann intmpArray) {
needDelete =TRUE;
for (AQCityInfoObject * ciObj inarray) {
if ([ciObj.cityName isEqualToString: ann.title]) {
needDelete =false;
continue;
}
}
if(needDelete) {
[_preDeleteMArray addObject: ann];
[_pointAnnotationMArray removeObject: ann];
}
}
//移除待删除的标注视图
[_mapView removeAnnotations: _preDeleteMArray];
pointAn =nil;
BOOL needAdd = TRUE;
//比较差异标注,更新或新增标注视图
for (AQCityInfoObject * obj inarray) {
needAdd =TRUE;
pointAn =nil;
for (BMKPointAnnotation * ann in _pointAnnotationMArray) {
if ([obj.cityName isEqualToString:ann.title]) {
needAdd =FALSE;
pointAn = ann;
continue;
}
}
if(needAdd) {
pointAn = [self addAnnotationViewWithCityInfoObject:obj];
[_pointAnnotationMArray addObject:pointAn];
}
else
{
BMKAnnotationView * annView = [_mapView viewForAnnotation:pointAn];
if(annView) {
[self updateAnnotationView:annView WithCityInfoObject:obj];
}
}
}
}
}
3.3 注意事项
3.3.1 不要再Storyboard或者xib中直接使用BMKMapView
因为BMKMapView的初始化需要先进行开发账号认证,因此不能在设计页面中直接添加BMKMapView。正确地初始化顺序是:
_mapManager = [[BMKMapManager alloc] init];
// 如果要关注网络及授权验证事件,请设定 generalDelegate参数
BOOL ret = [_mapManager start: @"在此处输入您的授权Key" generalDelegate: nil];
if(!ret) {
LOGERR(@"manager start failed!");
}
_bMapView = [[BMKMapView alloc] initWithFrame: CGRectMake(0, 0, 320, 480)];
// [[BMKMapView alloc] initWithFrame: CGRectMake(0, 0, 320, 480)];
self.mapView = _bMapView;
if (![self.view.subviews containsObject: self.mapView]) {
[self.view addSubview: self.mapView];
}
_bMapView.delegate = self;
[_bMapView setMapType: BMKMapTypeStandard];
