我在尝试为GMSMarker制作动画时遇到错误,我已经按照Google文档和各种指南进行了操作但是它一直会返回错误,下面是我的代码:

func placeMarker(coordinate: CLLocationCoordinate2D) {
    if locationMarker != nil {
        locationMarker.map = nil
    }

    locationMarker = GMSMarker(position: coordinate)
    locationMarker.icon = GMSMarker.markerImageWithColor(purple)
    locationMarker.appearAnimation = kGMSMarkerAnimationPop
    locationMarker.snippet = "The best place on earth."
    locationMarker.map = mapView
}

返回错误'kGMSMarkerAnimationPop'的模糊使用

任何帮助都会得到满足!
