Ios 使用JSQLocationMediaItem发送位置

我正在使用JSQMessagesViewController在我的应用程序中实现聊天。我想能够发送用户，我正在与我的位置聊天。这就是我所做的

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        self.latestLocation = locations[locations.count-1]

    }

  let sendLocation = UIAlertAction(title: "Send Location", style: .default, handler: { (action) -> Void in



            let loc: JSQLocationMediaItem = JSQLocationMediaItem(location: self.latestLocation)

            loc.appliesMediaViewMaskAsOutgoing = true

            let locmessage: JSQMessage = JSQMessage(senderId: self.senderId, senderDisplayName: self.senderDisplayName, date: NSDate() as Date!, media: loc)

            self.messages.append(locmessage)

            self.finishSendingMessage(animated: true)
            self.collectionView.reloadData()

            print("Location button tapped")
        })

        let cancelButton = UIAlertAction(title: "Cancel", style: .cancel, handler: { (action) -> Void in
            print("Cancel button tapped")
        })

        alertController.addAction(sendLocation)

        self.navigationController!.present(alertController, animated: true, completion: nil)

但当我点击“发送位置”按钮时，我得到的只是一个带有旋转轮子的图像气泡，它会永远持续。

在代码中添加解决方案

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    self.latestLocation = locations[locations.count-1]

}

let sendLocation = UIAlertAction(title: "Send Location", style: .default, handler: { (action) -> Void in



        let loc: JSQLocationMediaItem = JSQLocationMediaItem()
        loc.setLocation(self.latestLocation) { // Added completion handler for updating the map after getting the location.

        loc.appliesMediaViewMaskAsOutgoing = true

        let locmessage: JSQMessage = JSQMessage(senderId: self.senderId, senderDisplayName: self.senderDisplayName, date: NSDate() as Date!, media: loc)

        self.messages.append(locmessage)

        self.finishSendingMessage(animated: true)
        self.collectionView.reloadData()

        print("Location button tapped")
    })
 }

    let cancelButton = UIAlertAction(title: "Cancel", style: .cancel, handler: { (action) -> Void in
        print("Cancel button tapped")
    })

    alertController.addAction(sendLocation)

    self.navigationController!.present(alertController, animated: true, completion: nil)

您必须在完成位置对象创建后设置位置。

嘿，我正在尝试使用此代码，但具体是什么：self.latestLocation=locations[locations.count-1]您能解释一下吗？@GhiggzPikkoro self.latestLocation=locations[locations.count-1]用于从CLLocationManager委托方法中拾取最后一个位置。好的，我用另一种方法进行了操作，它也可以工作，但我想问您是否知道当用户用地图点击气泡时，它如何在所有视图中显示地图？根据你的说法可能吗？你这么做了吗？嘿，我正试图使用这段代码，但那到底是什么：self.latestLocation=locations[locations.count-1]你能解释一下吗？
