原生地图
1、什么是LBS
LBS: 基于位置的服务 Location Based Service
实际应用:大众点评，陌陌，微信，美团等需要用到地图或定位的App
2、定位方式
1.GPS定位 2.基站定位 3.WIFI定位
3、框架
MapKit:地图框架，显示地图
CoreLocation:定位框架，没有地图时也可以使用定位.
4、如何使用原生地图<MapKit> 和定位<CoreLocation>
MapKit：
1) 初始化MapView
_mapView = [[MKMapView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:_mapView];
2) 设置代理
_mapView.delegate = self;
3) 设置地图类型
_mapView.mapType = MKMapTypeStandard;
4) 允许显示自己的位置
_mapView.showsUserLocation = YES;
5) 设置地图中心坐标点
CLLocationCoordinate2D centerCoordinate = CLLocationCoordinate2DMake(22.540396,113.951832);
_mapView.centerCoordinate = centerCoordinate;
6) 设置地图显示区域
a) 设置缩放
MKCoordinateSpan span = MKCoordinateSpanMake(0.1, 0.1);
b) 设置区域
MKCoordinateRegion region = MKCoordinateRegionMake(centerCoordinate, span);
c) 显示区域
_mapView.region = region;
CoreLocation：
7) 初始化定位管理器
_manager = [[CLLocationManager alloc] init];
_manager.delegate = self;
8) iOS8定位
1. 在info.plist中添加 Privacy - Location Usage Description , NSLocationAlwaysUsageDescription
2. 在代码中加入
if ( [UIDevice currentDevice].systemVersion.floatValue >= 8.0 ) {
[_manager requestAlwaysAuthorization];
}
9) 开启定位
[_manager startUpdatingLocation];
10) 定位成功代理
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
NSLog(@"定位成功");
//获取定位的坐标
CLLocation *location = [locations firstObject];
//获取坐标
CLLocationCoordinate2D coordinate = location.coordinate;
NSLog(@"定位的坐标：%f,%f", coordinate.longitude, coordinate.latitude);
//停止定位
//[_manager stopUpdatingLocation];
}
11) 定位失败代理
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"定位失败”);
}
12) 屏幕坐标转经纬度坐标
CLLocationCoordinate2D cl2d = [_mapView convertPoint:point toCoordinateFromView:_mapView];
13) 反地理编码
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
//获取地标对象
CLPlacemark *mark = [placemarks firstObject];
}];
大头针（标注）：
14) 添加大头针
//创建大头针
MKPointAnnotation *pointAnn = [[MKPointAnnotation alloc] init];
//设置坐标
pointAnn.coordinate = CLLocationCoordinate2DMake(23.181297, 113.346877);
//设置标题
pointAnn.title = @"我的第一个大头针";
//设置副标题
pointAnn.subtitle = @"副标题";
//显示大头针，把大头针加入到地图上
[_mapView addAnnotation:pointAnn];
15) 大头针的复用及定制
#pragma mark - mapView 代理方法
//大头针View
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
//如果是自己当前位置的大头针，则不定制
if ( [annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
#if 1
// 1、自带的大头针视图
MKPinAnnotationView *pinAnnView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"ID"];
if ( !pinAnnView ) {
pinAnnView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"ID"];
}
//设置大头针的颜色
pinAnnView.pinColor = MKPinAnnotationColorPurple;
//设置掉落动画
pinAnnView.animatesDrop = YES;
//是否弹出气泡
pinAnnView.canShowCallout = YES;
//设置左视图
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
leftView.backgroundColor = [UIColor blueColor];
pinAnnView.leftCalloutAccessoryView = leftView;
//设置右视图
UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinAnnView.rightCalloutAccessoryView = rightBtn;
return pinAnnView;
#else
//2、自定义大头针视图
/*
* 区别于MKPinAnnotationView
* 1、可以设置大头针图片
* 2、不可以设置大头针颜色和掉落动画
*/
MKAnnotationView *customView = [mapView dequeueReusableAnnotationViewWithIdentifier:@"ID2"];
if ( !customView ) {
customView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"ID2"];
}
//设置点击大头针可以显示气泡
customView.canShowCallout = YES;
//设置大头针图片
customView.image = [UIImage imageNamed:@"marker"];
//设置左视图
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
leftView.backgroundColor = [UIColor blueColor];
customView.leftCalloutAccessoryView = leftView;
//设置右视图
UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
customView.rightCalloutAccessoryView = rightBtn;
return customView;
#endif
}
16) 移除大头针
[_mapView removeAnnotations:_mapView.annotations];
17) 添加长按手势，实现在地图的长按点添加一个大头针
//4、长按地图显示大头针
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];
[_mapView addGestureRecognizer:longPress];
#pragma mark - 长按手势
-(void)longPress:(UILongPressGestureRecognizer *)gesture
{
//避免多次调用 只允许开始长按状态才添加大头针
if (gesture.state != UIGestureRecognizerStateBegan) {
return;
}
//获取长按地图上的某个点
CGPoint point = [gesture locationInView:_mapView];
//把point转换成在地图上的坐标经纬度
CLLocationCoordinate2D coordinate = [_mapView convertPoint:point toCoordinateFromView:_mapView];
//添加长按的大头针
MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init];
annotation.coordinate = coordinate;
annotation.title = @"长按的大头针";
annotation.subtitle = @"副标题";
[_mapView addAnnotation:annotation];
}

{
NSLog(@"定位成功");
CLLocation *location = userLocation.location;
CLLocationCoordinate2D coordinate = location.coordinate;
NSLog(@"我的坐标位置：%f, %f", coordinate.longitude, coordinate.latitude);
// 定位后，可设置停止定位
// _maMapView.showsUserLocation = NO;
}
13) 添加标注（大头针）

[_maMapView addAnnotation:annotation]; //将标注添加在地图上
14) 标注的复用及定制
#pragma mark - 定制标注视图（和原生地图定制方式类似）
- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)annotation
{
//不定制自己位置的标注视图
if ( [annotation isKindOfClass:[MAUserLocation class]]) {
return nil;
}
#if 1
// 1、自带的标注视图
MAPinAnnotationView *pinAnnView = (MAPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"ID"];
if ( !pinAnnView ) {
pinAnnView = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"ID"];

pinAnnView.leftCalloutAccessoryView = leftView;
//设置右视图
UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinAnnView.rightCalloutAccessoryView = rightBtn;
return pinAnnView;
#else
//2、自定义标注视图
MAAnnotationView *customView = [mapView dequeueReusableAnnotationViewWithIdentifier:@"ID2"];
if ( !customView ) {
customView = [[MAAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"ID2"];
}
//设置点击大头针可以显示气泡
customView.canShowCallout = YES;

customView.image = [UIImage imageNamed:@"marker"];
//设置左视图
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
leftView.backgroundColor = [UIColor blueColor];
customView.leftCalloutAccessoryView = leftView;
//设置右视图
UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
customView.rightCalloutAccessoryView = rightBtn;
return customView;
#endif
}
15) 添加长按手势
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];
[_maMapView addGestureRecognizer:longPress];
#pragma mark -- 长按手势Action
-(void)longPress:(UILongPressGestureRecognizer *)longPress
{
if (longPress.state != UIGestureRecognizerStateBegan) {
return;
}
//获取点位置
CGPoint point = [longPress locationInView:_maMapView];
//将点位置转换成经纬度坐标
CLLocationCoordinate2D coordinate = [_maMapView convertPoint:point toCoordinateFromView:_maMapView];
//在该点添加一个大头针(标注)
MAPointAnnotation *pointAnn = [[MAPointAnnotation alloc] init];
pointAnn.coordinate = coordinate;
pointAnn.title = @"长按的大头针";
pointAnn.subtitle = @"副标题";
[_maMapView addAnnotation:pointAnn];
}
AMapSearchKit：
1) 搜索周边
0) 创建AMapSearchAPI对象，配置APPKEY，同时设置代理对象为self
searchAPI = [[AMapSearchAPI alloc] initWithSearchKey:APIKEY Delegate:self];
a) 创建搜索周边请求类
AMapPlaceSearchRequest *searchRequest = [[AMapPlaceSearchRequest alloc] init];
b) 设置搜索类型（按关键字搜索）
searchRequest.searchType = AMapSearchType_PlaceKeyword;
c) 设置关键字
searchRequest.keywords = keywordsTextField.text;
d) 设置搜索城市
searchRequest.city = @[@"广州"];
e) 开始搜索
[searchAPI AMapPlaceSearch:searchRequest];
2) 搜索周边回调方法
a) 搜索失败
- (void)searchRequest:(id)request didFailWithError:(NSError *)error
{
NSLog(@"搜索失败");
}
b) 搜索成功
-(void)onPlaceSearchDone:(AMapPlaceSearchRequest *)request response:(AMapPlaceSearchResponse *)response
{
//清空原来的标注（大头针）
[_maMapView removeAnnotations:_maMapView.annotations];
//判断是否为空
if (response) {
//取出搜索到的POI（POI：Point Of Interest）
for (AMapPOI *poi in response.pois) {
//poi的坐标
CLLocationCoordinate2D coordinate =
CLLocationCoordinate2DMake(poi.location.latitude, poi.location.longitude);
//地名
NSString *name = poi.name;
//地址
NSString *address = poi.address;
//用标注显示
MAPointAnnotation *pointAnn = [[MAPointAnnotation alloc] init];
pointAnn.coordinate = coordinate;
pointAnn.title = name;
pointAnn.subtitle = address;
[_maMapView addAnnotation:pointAnn];
}
}
}
3) 添加折线
#pragma mark - 画折线
-(void)drawPolyLine
{
//初始化点
NSArray *latitudePoints =[NSArray arrayWithObjects:
@"23.172223",
@"23.163385",
@"23.155411",
@"23.148765",
@"23.136935", nil];
NSArray *longitudePoints = [NSArray arrayWithObjects:
@"113.348665",
@"113.366056",
@"113.366128",
@"113.362391",
@"113.356785", nil];
// 创建数组
CLLocationCoordinate2D polyLineCoords[5];
for (int i=0; i<5; i++) {
polyLineCoords[i].latitude = [latitudePoints[i] floatValue];
polyLineCoords[i].longitude = [longitudePoints[i] floatValue];
}
// 创建折线对象
MAPolyline *polyLine = [MAPolyline polylineWithCoordinates:polyLineCoords count:5];
// 在地图上显示折线
[_maMapView addOverlay:polyLine];
}
#pragma mark - 定制折线视图
-(MAOverlayView *)mapView:(MAMapView *)mapView viewForOverlay:(id<MAOverlay>)overlay
{
if ([overlay isKindOfClass:[MAPolyline class]]) {
MAPolylineView *polyLineView = [[MAPolylineView alloc] initWithPolyline:overlay];
polyLineView.lineWidth = 2; //折线宽度
polyLineView.strokeColor = [UIColor blueColor]; //折线颜色
polyLineView.lineJoinType = kMALineJoinRound; //折线连接类型
return polyLineView;
}
return nil;
}
