iOS原生地图,模拟飞行器时时定位,画出飞行轨迹!

什么都不说先上效果图:

iOS原生地图,模拟飞行器时时定位,画出飞行轨迹!_第1张图片

1.导入地图所需的MapKit架包

2.创建位置管理器,请求授权

self.mgr= [CLLocationManagernew];

if([self.mgrrespondsToSelector:@selector(requestWhenInUseAuthorization)]) {

[self.mgrrequestWhenInUseAuthorization];

}

3.设置三种模式的地图

switch(sender.selectedSegmentIndex) {

case0:

self.myMapView.mapType=MKMapTypeStandard;

break;

case1:

self.myMapView.mapType=MKMapTypeSatellite;

break;

case2:

self.myMapView.mapType=MKMapTypeHybrid;

break;

default:

break;

}

4.封装大头针类

+(instancetype)myMKAnnotationViewWithMapView:(MKMapView*)mapView{

staticNSString*ID =@"datouzhen";

MyMKAnnotationView*annoView = (MyMKAnnotationView*)[mapViewdequeueReusableAnnotationViewWithIdentifier:ID];

if(annoView ==nil) {

annoView = [[MyMKAnnotationViewalloc]initWithAnnotation:nilreuseIdentifier:ID];

annoView.image= [UIImageimageNamed:@"飞行器"];

annoView.canShowCallout=true;

}

returnannoView;

}

5.设置大头针以及大头针飞行时的动画,和规划路线

-(void)mapView:(MKMapView*)mapView didAddAnnotationViews:(NSArray *)views{

for(MKAnnotationView*annoViewinviews) {

//1.记录原本的位置

if([annoView.annotationisKindOfClass:[MKUserLocationclass]]) {

return;

}

CGRectendFrame = annoView.frame;

//2.设置起点

if(self.annotaArray.count==0) {

annoView.frame=CGRectMake(annoView.frame.origin.x, annoView.frame.origin.y, endFrame.size.width, endFrame.size.height);

}else{

XYAnnotationXY*XY =self.annotaArray.lastObject;

annoView.frame=CGRectMake(XY.x, XY.y, endFrame.size.width, endFrame.size.height);

}

//3.将位置还原

[UIViewanimateWithDuration:0.2animations:^{

annoView.frame= endFrame;

if(self.sportLineArray.count>1){

NSLog(@"%lu",(unsignedlong)self.sportLineArray.count);

//[self drawSportLineLocationArray:self.sportLineArray];

[selfdrawLineWithLocationArray:self.sportLineArray];

}

}];

}

}

6.采用用手点击,来模拟飞行器飞行时的位置,反编码获取点。

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent*)event{

//1.获取点击的这个点

CGPointpoint = [[touchesanyObject]locationInView:self.myMapView];

XYAnnotationXY*anniXY = [XYAnnotationXYnew];

anniXY.x= point.x;

anniXY.y= point.y;

if(self.annotaArray.count==2) {

[self.annotaArrayremoveLastObject];

[self.annotaArrayinsertObject:anniXYatIndex:0];

}

if(self.annotaArray.count==1) {

[self.annotaArrayinsertObject:anniXYatIndex:0];

}

if(self.annotaArray.count==0) {

[self.annotaArrayaddObject:anniXY];

}

//2.将点转化成经纬度

CLLocationCoordinate2DCoordinate = [self.myMapViewconvertPoint:pointtoCoordinateFromView:self.myMapView];

MyAnnotationModel*annotationModel = [MyAnnotationModelnew];

annotationModel.coordinate= Coordinate;

CLGeocoder*geocoder = [CLGeocodernew];

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

if(self.sportLineArray.count==0) {

[self.sportLineArrayaddObject:location];

}elseif(self.sportLineArray.count==1){

[self.sportLineArrayaddObject:location];

}elseif(self.sportLineArray.count==2){

[self.sportLineArrayremoveObjectAtIndex:0];

[self.sportLineArrayaddObject:location];

}

[geocoderreverseGeocodeLocation:locationcompletionHandler:^(NSArray *_Nullableplacemarks,NSError*_Nullableerror) {

if(placemarks==0||error) {

return;

}

CLPlacemark*placemark = [placemarkslastObject];

annotationModel.title= placemark.locality;

annotationModel.subtitle= placemark.name;

}];

for(id annotataion2inself.myMapView.annotations) {

if([annotataion2isKindOfClass: annotationModel.class]) {

[self.myMapViewremoveAnnotation:annotataion2];

}

}

[self.myMapViewaddAnnotation:annotationModel];

}

7.规划路线

-(void)drawLineWithLocationArray:(NSArray*)sportLineArray{

intpointCount = (int)sportLineArray.count;

CLLocationCoordinate2D*coordinateArray = (CLLocationCoordinate2D*)malloc(pointCount *sizeof(CLLocationCoordinate2D));

for(inti = pointCount-2; i < pointCount; ++i) {

CLLocation*location = [sportLineArrayobjectAtIndex:i-pointCount+2];

coordinateArray[i-pointCount+2] = [locationcoordinate];

}

self.sportPolyline= [MKPolylinepolylineWithCoordinates:coordinateArraycount:2];

//跟踪画图

//[self.myMapView setVisibleMapRect:[self.sportPolyline boundingMapRect]];

[self.myMapViewaddOverlay:self.sportPolyline];

free(coordinateArray);

coordinateArray =NULL;

}

8.设置遮盖物,渲染。

- (MKOverlayRenderer*)mapView:(MKMapView*)mapView rendererForOverlay:(id)overlay{

MKPolylineRenderer*render = [[MKPolylineRendereralloc]initWithPolyline:overlay];

if([overlayisKindOfClass:[self.sportPolylineclass]]) {

render.lineWidth=3;

render.strokeColor= [UIColoryellowColor];

}

returnrender;

}
