添加自动布局约束后，GMS Mapview中心位于0,0左角

问题描述

一切正常，但是当我向情节提要中的GMSMapview添加自动布局约束时，地图视图的中心更改为左上角，我试图搜索可能的解决方案，但似乎无济于事。

我在viewWillAppear方法中设置了地图。

if let editGeofence = editGeofence {
    self.navigationItem.title = "Edit place"
    // take the points from this geofence and populate radius,name and place with it.
    let longitude = (editGeofence.longitude)
    let latitude = editGeofence.latitude
    let camera = GMSCameraPosition.camera(withTarget: CLLocationCoordinate2D(latitude: latitude,longitude: longitude),zoom: 17)
    mapView.animate(to: camera)
    nameOfPlace.text = editGeofence.placeName
    radiusValue.text = "\(Int(editGeofence.radius)) mts"
    radiusSlider.value = Float(editGeofence.radius/2000)
}

else {
    self.navigationItem.title = "Add a place"
    // use the default location coordinates and move the map there
    let lastLocation = Utils.getLastSavedCoordinates()
    let camera = GMSCameraPosition.camera(withTarget: lastLocation,zoom: 17)
    mapView.animate(to: camera)
}
// if location is passed take geofence to that place
if let sentLocation = sentLocation {
    let camera = GMSCameraPosition.camera(withTarget: sentLocation.coordinate,zoom: 17)
    mapView.animate(to: camera)
}
