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。 我希望能够将我正在聊天的用户发送到我的位置。 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) 

但是，当我点击发送位置按钮时，我只是得到一个带有旋转轮的图像气泡，它会永远存在。

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。
