我正在尝试开发基于Uber和Ola概念的应用程序。所以对于这个我需要整合谷歌地图的接送地点离子iOS。那么请告诉我如何使用Google地图在iOS中实现移动注释(汽车)动画。

使用Swift 3.1
Error:(29, 47) missing parameter type for expanded function ((x$1: <error>, x$2) => x$1.$plus(x$2))
Functor.listFunctor.map(List(1,2,3,4))(_ + _)
^
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()
从旧坐标和新坐标获取方位值的方法
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 }
}
