Question

我正在尝试将cllocationcoordinate2d转换为cllocation。我在下面的代码的第12行收到错误“容器文字中的预期表达式”。我也在第13行得到错误“无法将cllocationcoordinate2d类型的值转换为期望值cllocation”，但这是因为第12行无法正常工作。

@IBAction func makeEvent(sender: UIButton)
    {
        let center = CLLocationCoordinate2D(latitude: loc1.coordinate.latitude, longitude: loc1.coordinate.longitude)
        let lat: CLLocationDegrees = center.latitude
        let long: CLLocationDegrees = center.longitude
        self.pointAnnotation1 = MKPointAnnotation()
        self.pointAnnotation1.title = "Event"
        self.pointAnnotation1.coordinate = CLLocationCoordinate2D(latitude: lat, longitude: long)
        self.pinAnnotationView = MKPinAnnotationView(annotation: self.pointAnnotation1, reuseIdentifier: nil)
        self.mapView?.centerCoordinate = self.pointAnnotation1.coordinate
        self.mapView.addAnnotation(self.pinAnnotationView.annotation!)
        CLLocation *center = [[CLLocation alloc] initWithLatitude:latt longitude:longg]
        eventRecord.setObject(center, forKey: "event")
        let publicData = CKContainer.defaultContainer().publicCloudDatabase
        publicData.saveRecord(eventRecord) { record, error in
        }
        if error == nil
        {
            print("Location saved")
        }
        loadEvent(){ (error, records) in
            if error != nil {
                print("error fetching locations")
            } else {
                print("Found Event")
            }
        }
    }

你正在混淆客观c和swift。试试这个：

    let center = CLLocation(latitude: lat, longitude: long)

而不是：

    CLLocation *center = [[CLLocation alloc] initWithLatitude:latt longitude:longg]

在Swift中将CLLocationCoordinate2D转换为CLLocation时出错
