有没有可能在谷歌地图上制作工具栏？

Question

我试图在谷歌地图上添加一个UItoolbar，但地图覆盖了工具栏。

即使我将地图视图添加为子视图，地图视图也不会显示任何内容。在Google地图上制作工具栏是不可能的？

其他信息：

var camera:GMSCameraPosition = GMSCameraPosition() 
var mapView:GMSMapView = GMSMapView() 

override func viewDidLoad() { 
    super.viewDidLoad() 

    let manager = CLLocationManager() 
    if CLLocationManager.locationServicesEnabled() { 
     manager.startUpdatingLocation() 
    } 
    if CLLocationManager.authorizationStatus() == .NotDetermined { 
     manager.requestAlwaysAuthorization() 
    } 
    camera = GMSCameraPosition.cameraWithLatitude(lat,longitude:long, zoom:17.5, bearing:30, viewingAngle:40) 
    mapView = GMSMapView.mapWithFrame(CGRectZero, camera:camera) 

    var marker = GMSMarker() 
    marker.position = CLLocationCoordinate2DMake(lat, long) 
    marker.appearAnimation = kGMSMarkerAnimationPop 
    marker.title = locationName 

    if let mylocation = mapView.myLocation { 
     NSLog("User's location: %@", mylocation) 
    } else { 
     NSLog("User's location is unknown") 
    } 
    mapView.myLocationEnabled = true 
    self.view = mapView 
//  self.view.addSubview(mapView) 
    let toolbar: UIToolbar = UIToolbar() 
    toolbar.frame = CGRectMake(0, self.view.frame.size.height - 48, self.view.frame.size.width, 48) 
    toolbar.sizeToFit() 
    toolbar.backgroundColor = UIColor.redColor() 
    self.view.addSubview(toolbar) 
}

我会充分利用navigationcontroller来处理这个问题：

此视图控制器（GoogleMapController）已被其他视图控制器

Swift代码推。

GoogleMapViewController *mapVC = [[GoogleMapViewController alloc] init]; 
self.nc = [[UINavigationController alloc] initWithRootViewController:mapvc]; 
nc.navigationBar.translucent = NO; 
[nc setToolbarHidden:NO]; 
[mapvc addCustomerToolbar]; 

self.window.rootViewController = self.nc;

在您的mapview控制器 - 您可以将项目设置为导航工具栏 - 或添加自定义视图。

- (void)addCustomerToolbar { 
    CustomView *cv = [[CustomView alloc]init]; 
    [self.navigationController.toolbar addSubview:progToolbar]; 
}
