Ios Google Map Cluster 项目点击事件不起作用

Question

我正在使用适用于 IOS 的 Google 地图。我在哪里实现了集群，但集群和集群项目标记单击事件不起作用。但个别谷歌地图标记点击事件正在工作。

这是我的完整代码

import UIKit
import GoogleMaps
import Alamofire
import SwiftyJSON


let kCameraLatitude = 22.3475
let kCameraLongitude = 91.8123

今天正在处理这个问题，也尝试了相同的功能，但发现它不起作用，因为它是错误的。而不是：

func clusterManager(clusterManager: GMUClusterManager, didTapCluster cluster: GMUCluster) {
    let newCamera = GMSCameraPosition.camera(withTarget: cluster.position,
                                                zoom: mapView.camera.zoom + 1)
    let update = GMSCameraUpdate.setCamera(newCamera)
    mapView.moveCamera(update)
}

试试这个：（它看起来和上面的几乎一样，只是它的返回类型是 Bool）。

func clusterManager(_ clusterManager: GMUClusterManager, didTap cluster: GMUCluster) -> Bool {
    let newCamera = GMSCameraPosition.camera(withTarget: cluster.position,
                                             zoom: mapView.camera.zoom + 1)
    let update = GMSCameraUpdate.setCamera(newCamera)
    mapView.moveCamera(update)

    return false           
}

（使用 Swift 3）
