使用自定义注释移动动画IOS Swift喜欢Ola Uber App MapKit
**Here the car image where I want to only rotate car icon.**
在我的应用中，我每10秒钟从服务器接收一个位置 所以我想用动画制作自定义注释的动画 一点到另一点。
我想在iOS Swift 3中使用MapKit移动注释 如何将移动动画从一个位置移动到另一个位置。 我发送了viewController类代码 请仔细阅读并帮助我摆脱这个
感谢
我在这里添加自定义注释
var point : MyCustomAnnotation?
point = MyCustomAnnotation(coordinate: CLLocationCoordinate2D(latitude: self.latitude , longitude: self.longitude ))
point?.speed = speed
point?.dateTime = time
self.mapView.addAnnotation(point!)
After Than
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if annotation is MKUserLocation
{
return nil
}
UIView.animate(withDuration: 3) {
if(self.annotationView != nil )
{
self.annotationView?.removeFromSuperview()
}else{
}
self.annotationView = self.mapView.dequeueReusableAnnotationView(withIdentifier: "Pin")
if self.annotationView == nil{
self.annotationView = AnnotationView(annotation: annotation, reuseIdentifier: "Pin")
self.annotationView?.image = self.imagePin!
self.annotationView?.canShowCallout = false
}else{
self.annotationView?.annotation = annotation
}
let roatet = CLLocation(latitude: self.latitude, longitude: self.longitude)
.bearingToLocationDegrees(destinationLocation: CLLocation(latitude: self.rotLat, longitude: self.rotLng))
self.rotLat = self.latitude
self.rotLng = self.longitude
self.annotationView?.image = self.imagePin?.imageRotatedByDegrees(oldImage: self.imagePin!, deg: CGFloat(roatet))
return annotationView
}
另一个功能是
func mapView(_ mapView: MKMapView,
didSelect view: MKAnnotationView)
{
// 1
if view.annotation is MKUserLocation
{
// Don't proceed with custom callout
return
}
// 2
let starbucksAnnotation = view.annotation as! StarbucksAnnotation
let views = Bundle.main.loadNibNamed("CustomCalloutView", owner: nil, options: nil)
let calloutView = views?[0] as! CustomCalloutView
calloutView.lbAc.text = starbucksAnnotation.acV
calloutView.lbFuel.text = starbucksAnnotation.fuelV + "%"
calloutView.lbPower.text = starbucksAnnotation.powerV
calloutView.lbIgnation.text = starbucksAnnotation.ignitionV
calloutView.lbBattery.text = starbucksAnnotation.battry
calloutView.lbDate.text = starbucksAnnotation.dateTime
calloutView.center = CGPoint(x: view.bounds.size.width / 2, y: -calloutView.bounds.size.height*0.52)
view.addSubview(calloutView)
// UIView.animate(withDuration: 5) {
mapView.setCenter((view.annotation?.coordinate)!, animated: true)
// }
}
func mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView) {
if view.isKind(of: AnnotationView.self)
{
for subview in view.subviews
{
subview.removeFromSuperview()
}
}
}

据我了解你的问题，我提出这个解决方案，其中我在两个地点之间画了一个polly直播，一旦用户点击该汽车注释汽车注释将在类似于超级的路径上运行。
您可以通过自定义方法moveCar（_ destinationCoordinate：CLLocationCoordinate2D）并传递从服务器获取的坐标的最新值来为自定义注释设置动画。
