Apple：怎么样，大不大？
Android：what are talking about？is very small
哈哈，进归正题
今天讲的是iOS的开发中的一个生活实用技巧，本篇文章没有什么过多文字讲解。代码为主要，希望大家喜欢
first（首先）：首先去高德地图官网下载相关的SDK（如下图）：
按照高德地图官网的步骤继续添加所需要的依赖库
根据项目的bundleID前往高德地图API中创建引用并申请相关的key
高德地图应用管理后台
代码部分如图下：
#import “AppDelegate.h”
#import “ViewController.h”
#import <AMapLocationKit/AMapLocationKit.h>
#import <AMapFoundationKit/AMapFoundationKit.h>
static NSString *APIKey = @“a1500980e29b7ca7612a46c19e0d2e3a”;
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
[self.window makeKeyAndVisible];
self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:[ViewController new]];
[AMapServices sharedServices].apiKey = APIKey;
return YES;
}
定位用户当前位置
在你定位类中导入头文件（这个文件是与地图相关的）
初始化地图view：
-
(void)initMapView{
self.mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 64 + 44, SCREEN_WIDTH, 300)];
self.mapView.delegate = self;
self.mapView.mapType = MAMapTypeStandard;
self.mapView.showsScale = NO;
self.mapView.showsCompass = NO;
self.mapView.showsUserLocation = YES;
[self.view addSubview:self.mapView];
UIButton *localButton = [UIButton buttonWithType:UIButtonTypeCustom];
localButton.backgroundColor = [UIColor redColor];
localButton.frame = CGRectMake(SCREEN_WIDTH - 60, 240, 50, 50);
[localButton addTarget:self action:@selector(localButtonAction) forControlEvents:UIControlEventTouchUpInside];
localButton.layer.cornerRadius = 25;
localButton.clipsToBounds = YES;
[localButton setImage:[UIImage imageNamed:@“定位”] forState:UIControlStateNormal];
[self.mapView addSubview:localButton];
}
——————————————
/ 定位SDK -
(void)configLocationManager {
self.locationManager = [[AMapLocationManager alloc] init];
[self.locationManager setDelegate:self];
[self.locationManager setDesiredAccuracy:kCLLocationAccuracyHundredMeters];
//单次定位超时时间
[self.locationManager setLocationTimeout:6];
[self.locationManager setReGeocodeTimeout:3];
}
开启定位实操:
(void)locateAction {
[self showHudInView:self.view hint:@“正在定位…”];
//带逆地理的单次定位
[self.locationManager requestLocationWithReGeocode:YES completionBlock:^(CLLocation *location, AMapLocationReGeocode *regeocode, NSError *error) {
if (error) {
[self showHint:@“定位错误” yOffset:-180];
NSLog(@“locError:{%ld - %@};”,(long)error.code,error.localizedDescription);
if (error.code == AMapLocationErrorLocateFailed) {
return ;
}
}
//定位信息
NSLog(@“location:%@”, location);
if (regeocode)
{
[self hideHud];
self.currentLocationCoordinate = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude);
self.city = regeocode.city;
[self showMapPoint];
[self setCenterPoint];
self.request.location = [AMapGeoPoint locationWithLatitude:location.coordinate.latitude longitude:location.coordinate.longitude];
[self.mapSearch AMapPOIAroundSearch:self.request];
}
}];
}
定位完之后检查一下，展示大头针到当前位置，若没有，看下有没有导入高德地图文件资源 -
(void)showMapPoint{
[_mapView setZoomLevel:15.1 animated:YES];
[_mapView setCenterCoordinate:self.currentLocationCoordinate animated:YES];
} -
(void)setCenterPoint{
MAPointAnnotation * centerAnnotation = [[MAPointAnnotation alloc] init];//初始化注解对象
centerAnnotation.coordinate = self.currentLocationCoordinate;//定位经纬度
centerAnnotation.title = @"";
centerAnnotation.subtitle = @"";
[self.mapView addAnnotation:centerAnnotation];//添加注解
}
#pragma mark - MAMapView Delegate -
(MAAnnotationView *)mapView:(MAMapView )mapView
viewForAnnotation:(id)annotation {
if ([annotation isKindOfClass:[MAPointAnnotation class]]) {
static NSString pointReuseIndentifier = @“pointReuseIndentifier”;
MAPinAnnotationViewannotationView = (MAPinAnnotationView)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndentifier];
if (annotationView == nil)
{
annotationView = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pointReuseIndentifier];
}
annotationView.canShowCallout= YES; //设置气泡可以弹出，默认为NO
annotationView.animatesDrop = YES; //设置标注动画显示，默认为NO
annotationView.draggable = YES; //设置标注可以拖动，默认为NO
annotationView.pinColor = MAPinAnnotationColorRed;
return annotationView;
}
return nil;
}
可自定义搜索的内容，定位成功之后用户可以获取到当前的经纬度地址等一系列信息
