当我将注释添加到地图时,它们有时会显示,有时不会取决于它们彼此之间的距离.如果他们在同一个房子里,就说一个人不会出现.我如何让他们两个显示？我是否需要制作自定义注释类？我听说ios11有一个丛集功能,我需要使用它吗？这是代码(删节):

import UIKit
import MapKit
import Firebase

class GameViewController: UIViewController {


@IBOutlet weak var mapView: MKMapView!

fileprivate var locations = [CLLocation]()
fileprivate var userLocations = [(loc: CLLocation, name: String, team: String)]()
fileprivate var userAnnotations = [MKAnnotation]()
fileprivate var hasBeenUP = false

var ref: FIRDatabaseReference!
let uid = FIRAuth.auth()!.currentUser!.uid

var timer = Timer()
var timeLeft = 0.0
var firstTimer = Timer()

var name = ""
var team = ""

override func viewDidLoad() {
    super.viewDidLoad()
    let center = CLLocationCoordinate2D(latitude: 47.786769, longitude: -20.413634) …

我有下面的代码,我的目标是让mac识别具有Multipeer Connectivity的iOS设备.这在大多数情况下起作用,除了当我运行这两个时我得到两个 "FOUND !!!" 在控制台中.我怎样才能解决这个问题？

这是我的iOS设备代码:

import UIKit
import MultipeerConnectivity

class ViewController: UIViewController, MCNearbyServiceBrowserDelegate,      MCNearbyServiceAdvertiserDelegate {


let browser = MCNearbyServiceBrowser(peer: MCPeerID(displayName: "iOS Device"), serviceType: "example-test")
let peerID = MCPeerID(displayName: "iOS Device")
let advertiser = MCNearbyServiceAdvertiser(peer: MCPeerID(displayName: "iOS Device"), discoveryInfo: nil, serviceType: "example-test")



override func viewDidLoad() {
    super.viewDidLoad()
    advertiser.delegate = self
    advertiser.startAdvertisingPeer()
    browser.delegate = self
    browser.startBrowsingForPeers()
}

func browser(_ browser: MCNearbyServiceBrowser, lostPeer peerID: MCPeerID) {

}

func browser(_ browser: MCNearbyServiceBrowser, didNotStartBrowsingForPeers error: Error) {

}

func browser(_ browser: MCNearbyServiceBrowser, foundPeer …
