day8---地图

//********** 苹果自带的地图 ************
info 里面添加
NSLocationAlwaysUsageDescription YES
NSLocationWhenInUseUsageDescription YES
一、创建地图对象 【两个步骤：创建地图对象，添加到视图上】
self.map = [[MKMapView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height+60)];

//********* 地图相关属性 ************
//1.显示指南针【 7.0 之后的方法】

// self.map.showsScale = YES;
//2.显示比例的方法 7.0 之后的方法】
// self.map.showsScale = YES;
//3.左右滑动
self.map.zoomEnabled = YES;
//4.上下滑动
self.map.scrollEnabled = YES;

self.map.delegate = self;

//将地图对象添加到视图上
[self.view addSubview:self.map];

pragma mark -MKMapViewDelegate 【地图对象遵守的协议】

//是为了更换大头针 变成自定义的大头针

• (nullable MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation
  {

}

二、创建定位对象 【两个步骤：创建定位对象，添加到视图上】

//创建定位对象
self.cllManager = [[CLLocationManager alloc] init];

//******** 定位对象相关属性 **********
//1.精确到100m范围
self.cllManager.distanceFilter = 100;
//2.一直定位
self.cllManager.desiredAccuracy = kCLLocationAccuracyBest;
//3.判断版本
if ([[[UIDevice currentDevice] systemVersion] floatValue]>= 8.0) {
    
    NSLog(@"%f",[[[UIDevice currentDevice] systemVersion] floatValue]);
    
    [self.cllManager requestAlwaysAuthorization];
    [self.cllManager requestWhenInUseAuthorization];
    
}
self.cllManager.delegate = self;

//将定位对象添加到视图上
[self.cllManager startUpdatingLocation];

pragma mark -CLLocationManagerDelegate 【定位对象遵守的协议】

//代理方法中进行定位 【旧的方法】

• (void)locationManager:(CLLocationManager *)manager
  didUpdateToLocation:(CLLocation *)newLocation
  fromLocation:(CLLocation *)oldLocation __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_6, __MAC_NA, __IPHONE_2_0, __IPHONE_6_0)
  {
  //MKCoordinateSpan 进行定位中，经纬度定位的一个结构体
  MKCoordinateSpan span = MKCoordinateSpanMake(0.01, 0.01);

  //MKCoordinateRegion 这是一个结构体，里面有两个结构体
  MKCoordinateRegion region = MKCoordinateRegionMake(newLocation.coordinate, span);

  [self.map setRegion:region animated:YES];

  //系统的大头针对象 【两个步骤：创建大头针对象，将大头针对象添加到地图上】

MKPointAnnotation *pin = [[MKPointAnnotation alloc] init];      【创建大头针对象】

//******* 大头针相关属性 **********
//1.将新的经纬度赋值给大头针的经纬度，显示大头针；
pin.coordinate = newLocation.coordinate;
//2.标题
pin.title = @"标题";
//3.副标题
pin.subtitle = @"副标题";

//添加一个大头针对象
[self.map addAnnotation:pin];
//添加多个大头针对象

// [self.map addAnnotations:<#(NSArray *)#>];

//知道经纬度  自己定位
CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(30.4538967846, 114.4265225293);

MKCoordinateSpan span1 = MKCoordinateSpanMake(0.01, 0.01);
MKCoordinateRegion region1 = MKCoordinateRegionMake(coordinate, span1);

[self.map setRegion:region1 animated:YES];


MKPointAnnotation *pin1 = [[MKPointAnnotation alloc] init];
pin1.coordinate = coordinate;
pin1.title = @"金融港B26";
pin1.subtitle = @"千峰";
[self.map addAnnotation:pin1];

}

//代理方法中进行定位 【新的方法】
//- (void)locationManager:(CLLocationManager *)manager
// didUpdateLocations:(NSArray *)locations __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_6_0)
//{
//
//
//
//}
