我正在尝试开发一个基于 Uber 和 Ola 之类的概念的应用程序。因此,为此我需要集成谷歌地图以获取 iOS 的接送位置。所以请告诉我如何使用谷歌地图在iOS中实现移动注释(汽车)动画。

最佳答案

使用 Swift 3.1

        var oldCoodinate: CLLocationCoordinate2D? = CLLocationCoordinate2DMake(CDouble((data.value(forKey: "lat") as? CLLocationCoordinate2D)), CDouble((data.value(forKey: "lng") as? CLLocationCoordinate2D)))
var newCoodinate: CLLocationCoordinate2D? = CLLocationCoordinate2DMake(CDouble((data.value(forKey: "lat") as? CLLocationCoordinate2D)), CDouble((data.value(forKey: "lng") as? CLLocationCoordinate2D)))
driverMarker.groundAnchor = CGPoint(x: CGFloat(0.5), y: CGFloat(0.5))
driverMarker.rotation = getHeadingForDirection(fromCoordinate: oldCoodinate, toCoordinate: newCoodinate)
//found bearing value by calculation when marker add
driverMarker.position = oldCoodinate
//this can be old position to make car movement to new position
driverMarker.map = mapView_
//marker movement animation
CATransaction.begin()
CATransaction.setValue(Int(2.0), forKey: kCATransactionAnimationDuration)
CATransaction.setCompletionBlock({() -> Void in
driverMarker.groundAnchor = CGPoint(x: CGFloat(0.5), y: CGFloat(0.5))
driverMarker.rotation = CDouble(data.value(forKey: "bearing"))
//New bearing value from backend after car movement is done
})
driverMarker.position = newCoodinate
//this can be new position after car moved from old position to new position with animation
driverMarker.map = mapView_
driverMarker.groundAnchor = CGPoint(x: CGFloat(0.5), y: CGFloat(0.5))
driverMarker.rotation = getHeadingForDirection(fromCoordinate: oldCoodinate, toCoordinate: newCoodinate)
//found bearing value by calculation
CATransaction.commit()

extension Int {
var degreesToRadians: Double { return Double(self) * .pi / 180 }
}
extension FloatingPoint {
var degreesToRadians: Self { return self * .pi / 180 }
var radiansToDegrees: Self { return self * 180 / .pi }
}

从新旧坐标获取方位值的方法

func getHeadingForDirection(fromCoordinate fromLoc: CLLocationCoordinate2D, toCoordinate toLoc: CLLocationCoordinate2D) -> Float {

let fLat: Float = Float((fromLoc.latitude).degreesToRadians)
let fLng: Float = Float((fromLoc.longitude).degreesToRadians)
let tLat: Float = Float((toLoc.latitude).degreesToRadians)
let tLng: Float = Float((toLoc.longitude).degreesToRadians)
let degree: Float = (atan2(sin(tLng - fLng) * cos(tLat), cos(fLat) * sin(tLat) - sin(fLat) * cos(tLat) * cos(tLng - fLng))).radiansToDegrees
if degree >= 0 {
return degree
}
else {
return 360 + degree
}
}

objective-c 代码: Move GMSMarker on Google Map Like UBER
