原生地圖
1、什么是LBS
LBS: 基於位置的服務 Location Based Service
實際應用:大眾點評，陌陌，微信，美團等需要用到地圖或定位的App
2、定位方式
1.GPS定位 2.基站定位 3.WIFI定位
3、框架
MapKit:地圖框架，顯示地圖
CoreLocation:定位框架，沒有地圖時也可以使用定位.
4、如何使用原生地圖<MapKit> 和定位<CoreLocation>
MapKit：
1) 初始化MapView
_mapView = [[MKMapView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:_mapView];
2) 設置代理
_mapView.delegate = self;
3) 設置地圖類型
_mapView.mapType = MKMapTypeStandard;
4) 允許顯示自己的位置
_mapView.showsUserLocation = YES;
5) 設置地圖中心坐標點
CLLocationCoordinate2D centerCoordinate = CLLocationCoordinate2DMake(22.540396,113.951832);
_mapView.centerCoordinate = centerCoordinate;
6) 設置地圖顯示區域
a) 設置縮放
MKCoordinateSpan span = MKCoordinateSpanMake(0.1, 0.1);
b) 設置區域
MKCoordinateRegion region = MKCoordinateRegionMake(centerCoordinate, span);
c) 顯示區域
_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. 在代碼中加入
if ( [UIDevice currentDevice].systemVersion.floatValue >= 8.0 ) {
[_manager requestAlwaysAuthorization];
}
9) 開啟定位
[_manager startUpdatingLocation];
10) 定位成功代理
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
NSLog(@"定位成功");
//獲取定位的坐標
CLLocation *location = [locations firstObject];
//獲取坐標
CLLocationCoordinate2D coordinate = location.coordinate;
NSLog(@"定位的坐標：%f,%f", coordinate.longitude, coordinate.latitude);
//停止定位
//[_manager stopUpdatingLocation];
}
11) 定位失敗代理
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"定位失敗”);
}
12) 屏幕坐標轉經緯度坐標
CLLocationCoordinate2D cl2d = [_mapView convertPoint:point toCoordinateFromView:_mapView];
13) 反地理編碼
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
//獲取地標對象
CLPlacemark *mark = [placemarks firstObject];
}];
大頭針（標注）：
14) 添加大頭針
//創建大頭針
MKPointAnnotation *pointAnn = [[MKPointAnnotation alloc] init];
//設置坐標
pointAnn.coordinate = CLLocationCoordinate2DMake(23.181297, 113.346877);
//設置標題
pointAnn.title = @"我的第一個大頭針";
//設置副標題
pointAnn.subtitle = @"副標題";
//顯示大頭針，把大頭針加入到地圖上
[_mapView addAnnotation:pointAnn];
15) 大頭針的復用及定制
#pragma mark - mapView 代理方法
//大頭針View
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
//如果是自己當前位置的大頭針，則不定制
if ( [annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
#if 1
// 1、自帶的大頭針視圖
MKPinAnnotationView *pinAnnView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"ID"];
if ( !pinAnnView ) {
pinAnnView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"ID"];
}
//設置大頭針的顏色
pinAnnView.pinColor = MKPinAnnotationColorPurple;
//設置掉落動畫
pinAnnView.animatesDrop = YES;
//是否彈出氣泡
pinAnnView.canShowCallout = YES;
//設置左視圖
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
leftView.backgroundColor = [UIColor blueColor];
pinAnnView.leftCalloutAccessoryView = leftView;
//設置右視圖
UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinAnnView.rightCalloutAccessoryView = rightBtn;
return pinAnnView;
#else
//2、自定義大頭針視圖
/*
* 區別於MKPinAnnotationView
* 1、可以設置大頭針圖片
* 2、不可以設置大頭針顏色和掉落動畫
*/
MKAnnotationView *customView = [mapView dequeueReusableAnnotationViewWithIdentifier:@"ID2"];
if ( !customView ) {
customView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"ID2"];
}
//設置點擊大頭針可以顯示氣泡
customView.canShowCallout = YES;
//設置大頭針圖片
customView.image = [UIImage imageNamed:@"marker"];
//設置左視圖
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
leftView.backgroundColor = [UIColor blueColor];
customView.leftCalloutAccessoryView = leftView;
//設置右視圖
UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
customView.rightCalloutAccessoryView = rightBtn;
return customView;
#endif
}
16) 移除大頭針
[_mapView removeAnnotations:_mapView.annotations];
17) 添加長按手勢，實現在地圖的長按點添加一個大頭針
//4、長按地圖顯示大頭針
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];
[_mapView addGestureRecognizer:longPress];
#pragma mark - 長按手勢
-(void)longPress:(UILongPressGestureRecognizer *)gesture
{
//避免多次調用 只允許開始長按狀態才添加大頭針
if (gesture.state != UIGestureRecognizerStateBegan) {
return;
}
//獲取長按地圖上的某個點
CGPoint point = [gesture locationInView:_mapView];
//把point轉換成在地圖上的坐標經緯度
CLLocationCoordinate2D coordinate = [_mapView convertPoint:point toCoordinateFromView:_mapView];
//添加長按的大頭針
MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init];
annotation.coordinate = coordinate;
annotation.title = @"長按的大頭針";
annotation.subtitle = @"副標題";
[_mapView addAnnotation:annotation];
}

[_maMapView addGestureRecognizer:longPress];
#pragma mark -- 長按手勢Action
-(void)longPress:(UILongPressGestureRecognizer *)longPress
{
if (longPress.state != UIGestureRecognizerStateBegan) {
return;
}
//獲取點位置
CGPoint point = [longPress locationInView:_maMapView];
//將點位置轉換成經緯度坐標
CLLocationCoordinate2D coordinate = [_maMapView convertPoint:point toCoordinateFromView:_maMapView];
//在該點添加一個大頭針(標注)
MAPointAnnotation *pointAnn = [[MAPointAnnotation alloc] init];
pointAnn.coordinate = coordinate;
pointAnn.title = @"長按的大頭針";
pointAnn.subtitle = @"副標題";
[_maMapView addAnnotation:pointAnn];
}
AMapSearchKit：
1) 搜索周邊
0) 創建AMapSearchAPI對象，配置APPKEY，同時設置代理對象為self
searchAPI = [[AMapSearchAPI alloc] initWithSearchKey:APIKEY Delegate:self];
a) 創建搜索周邊請求類
AMapPlaceSearchRequest *searchRequest = [[AMapPlaceSearchRequest alloc] init];
b) 設置搜索類型（按關鍵字搜索）
searchRequest.searchType = AMapSearchType_PlaceKeyword;
c) 設置關鍵字
searchRequest.keywords = keywordsTextField.text;
d) 設置搜索城市
searchRequest.city = @[@"廣州"];
e) 開始搜索
[searchAPI AMapPlaceSearch:searchRequest];
2) 搜索周邊回調方法
a) 搜索失敗
- (void)searchRequest:(id)request didFailWithError:(NSError *)error
{
NSLog(@"搜索失敗");
}
b) 搜索成功
-(void)onPlaceSearchDone:(AMapPlaceSearchRequest *)request response:(AMapPlaceSearchResponse *)response
{
//清空原來的標注（大頭針）
[_maMapView removeAnnotations:_maMapView.annotations];
//判斷是否為空
if (response) {
//取出搜索到的POI（POI：Point Of Interest）
for (AMapPOI *poi in response.pois) {
//poi的坐標
CLLocationCoordinate2D coordinate =
CLLocationCoordinate2DMake(poi.location.latitude, poi.location.longitude);
//地名
NSString *name = poi.name;
//地址
NSString *address = poi.address;
//用標注顯示
MAPointAnnotation *pointAnn = [[MAPointAnnotation alloc] init];
pointAnn.coordinate = coordinate;
pointAnn.title = name;
pointAnn.subtitle = address;
[_maMapView addAnnotation:pointAnn];
}
}
}
3) 添加折線
#pragma mark - 畫折線
-(void)drawPolyLine
{
//初始化點
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];
// 創建數組
CLLocationCoordinate2D polyLineCoords[5];
for (int i=0; i<5; i++) {
polyLineCoords[i].latitude = [latitudePoints[i] floatValue];
polyLineCoords[i].longitude = [longitudePoints[i] floatValue];
}
// 創建折線對象
MAPolyline *polyLine = [MAPolyline polylineWithCoordinates:polyLineCoords count:5];
// 在地圖上顯示折線
[_maMapView addOverlay:polyLine];
}
#pragma mark - 定制折線視圖
-(MAOverlayView *)mapView:(MAMapView *)mapView viewForOverlay:(id<MAOverlay>)overlay
{
if ([overlay isKindOfClass:[MAPolyline class]]) {
MAPolylineView *polyLineView = [[MAPolylineView alloc] initWithPolyline:overlay];
polyLineView.lineWidth = 2; //折線寬度
polyLineView.strokeColor = [UIColor blueColor]; //折線顏色
polyLineView.lineJoinType = kMALineJoinRound; //折線連接類型
return polyLineView;
}
return nil;
}
