iOS - 百度地图最基本操作(定位,手势添加自定义标注)

用 cocoapods 导入百度SDK, 然后开始...

#import "ViewController.h"

#import <BaiduMapAPI_Map/BMKMapView.h>

#import <BaiduMapAPI_Map/BMKPointAnnotation.h>

#import <BaiduMapAPI_Map/BMKPinAnnotationView.h>

@interface ViewController ()<BMKMapViewDelegate,CLLocationManagerDelegate> {

    BMKMapView *_mapView;

}

@property (nonatomic,strong)CLLocationManager *manager;

@end

@implementation ViewController

    [_mapViewviewWillAppear];

    _mapView.delegate =self;

}

    [_mapViewviewWillDisappear];

    _mapView.delegate =nil;

}

- (void)viewDidLoad {

    [superviewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    

    _mapView = [[BMKMapViewalloc] initWithFrame:self.view.bounds];

    [self.viewaddSubview:_mapView];

    

    self.manager = [[CLLocationManageralloc] init];

    

    if(![CLLocationManagerlocationServicesEnabled]){

        NSLog(@"bu ke yong");

        return;

    }

    NSLog(@"ke yong");

    //    CLLocationManager这个类是用来定位的

    self.manager = [[CLLocationManageralloc]init];

    //    间隔多少米去重新定位

    self.manager.distanceFilter =10;

    //   这个属性是设计定位的精确度

    //    kCLLocationAccuracyBest这个是最好的精确度

    self.manager.desiredAccuracy = kCLLocationAccuracyBest;

    //    设置代理

    self.manager.delegate =self;

    

    //    如果当前设备大于等于8.0做一下特殊设置

    if ([[UIDevicecurrentDevice].systemVersionfloatValue]>=8.0)

    }

    {

        [self.managerallowsBackgroundLocationUpdates];//允许后台定位更新

    }

    //    开始定位

    [self.managerstartUpdatingLocation];

    

    // 手势操作

    UILongPressGestureRecognizer *gesture = [[UILongPressGestureRecognizeralloc] initWithTarget:selfaction:@selector(longPressOption:)];

    gesture.minimumPressDuration =0.5;  // 默认就是 0.5s

    [_mapViewaddGestureRecognizer:gesture];

}

//这个代理方法是在定位失败的时候会调用

-(void)locationManager:(CLLocationManager *)manager didFailWithError:(nonnullNSError *)error{

    NSLog(@"==error===>>>%@",error.localizedDescription);

    [geocoder reverseGeocodeLocation:locationcompletionHandler:^(NSArray<CLPlacemark *> *_Nullable placemarks, NSError * _Nullable error) {

        //        CLPlacemark这个类里面装的是你当前定位到的那个地点的信息

        CLPlacemark *mark = [placemarksfirstObject];

#pragma mark - 为地图标注点添加长按手势

- (void)longPressOption:(UILongPressGestureRecognizer *)gesture {

    

    if (gesture.state ==UIGestureRecognizerStateRecognized) {

        CGPoint point = [gesturelocationInView:_mapView];

        CLLocationCoordinate2D coord = [_mapViewconvertPoint:point toCoordinateFromView:_mapView];

        

        CLGeocoder *geocoder = [[CLGeocoderalloc]init];

        CLLocation *location = [[CLLocationalloc]initWithLatitude:coord.latitudelongitude:coord.longitude];

        [geocoder reverseGeocodeLocation:locationcompletionHandler:^(NSArray<CLPlacemark *> *_Nullable placemarks, NSError * _Nullable error) {

            

            CLPlacemark *mark = [placemarkslastObject];

            

            BMKPointAnnotation *pointAnnotation = [[BMKPointAnnotationalloc] init];

            pointAnnotation.title = mark.locality;

            pointAnnotation.subtitle = mark.name;

            pointAnnotation.coordinate = coord;

            [_mapViewaddAnnotation:pointAnnotation];

        }];

    }

}

#pragma mark - 标注按钮点击事件

- (void)sendClick {

    NSLog(@"这里是点击所有标注都会调用的方法,,,");

}

基本操作就是这些，后续会更新详细操作的文章。。。
