  right now I can do this inside a viewcontroller's view succesfully

  ANy ideas on how to do this..

  I couldn't think a way how to do this without breaking the constraints

  any ideas,suggestions are welcome
• Delegates with Swift

  Currently I have a ViewController with a TableView and a custom Header containing a back button. What I want is to say from the header class that the ViewController has to go back to the previous ViewController. The problem I'm facing is that I'm conforming the protocol and the action of the button is received but the debugger doesn't go to the dismiss function. Here's the code:

      protocol StoresFilterHeaderViewDelegate: class {
          func onBackButtonTap();
      }
      class StoresFilterHeaderView: UICollectionReusableView {
  
          weak var delegate: StoresFilterHeaderViewDelegate?;
          @IBOutlet weak var lbSubcategory: UILabel!
          @IBOutlet weak var ivSubcategory: UIImageView!
  
          // MARK: Actions
  
            @IBAction func onBackToMomentDetailButtonTap(_ sender: AnyObject) {
                  self.delegate?.onBackButtonTap();
                  print("button pressed");
        }
      }
  

  "button pressed" is printed well

  ---

  class StoresFilterViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, StoresFilterHeaderViewDelegate {
  
      func onBackButtonTap() {
          print("segueback")
      }
  

  "segueback" is not being printed
• Unreal Engine / IOS - Associated Domains / Universal links

  Was wondering how to set up IOS Universal Links / Associated Domains in Unreal Engine.

  Basically we have two apps, one an older app built in IOS native/Xcode and a new side app showing off some new features/marketing that was built in Unreal Engine 4.18 (BluePrints only). The goal is to have them be able to deep link to eachother and make use of Universal Links overall for marketing/usage purposes. This isn't a problem with the older IOS native app as XCode can handle this but there seems to be no documentation on how to make sure the entitlements are setup correctly in Unreal Engine for this.

  I'm probably missing something very simple (like the naming structure of the Bundle Identifier) but curious on what to do in that regard.

• Why do layer shadows not work within a UIScrollView?

  My intention: I'd like to draw a shadow around a view. This sounds simple, so I made my own subclass of UIView as following:

  @IBDesignable
  class RoundedView: UIView {
  
      @IBInspectable var cornerRadius : CGFloat = 0 {
          didSet {
              layer.cornerRadius = cornerRadius
          }
      }
  
      @IBInspectable var borderWidth : CGFloat = 0 {
          didSet {
              layer.borderWidth = borderWidth
          }
      }
      @IBInspectable var borderColor : UIColor? {
          didSet {
              layer.shadowOpacity = 1
              layer.shadowRadius = 0
              layer.shadowOffset = CGSize(width: 0, height: 0)
              layer.shadowColor = UIColor.gray.cgColor
              layer.shadowPath = UIBezierPath(rect: self.bounds).cgPath
          }
  
      }
  }
  

  Just to test this out, I set the shadowRadius etc. to a constant value.

  This works as intended when dragging a UIView onto a UIViewController's main view in Xcode InterfaceBuilder; however, it does not seem to work with the following structure (see the screenshot):

  

  where the RoundedView is my custom view from above, the Gradient View is just a normal UIView (color gradient).

  When running the app in the simulator, I get the following output:

  

  As you can see, the shadow goes way too far to the right. I also checked both the shadowPath and the bounds of the view, they're equal.

  The shadowPath, bounds and frame:

  Path 0x608000236b00:
    moveto (0, 0)
      lineto (300, 0)
      lineto (300, 52)
      lineto (0, 52)
      closepath
  
  (0.0, 0.0, 300.0, 52.0)
  (37.0, 397.5, 300.0, 52.0)
  

  It's strange that this only appears within the UIScrollView.

  In addition, if I click on "Debug View Hierarchy", it is drawn correctly in Xcode.

  Can someone reproduce this?

  Thanks for help.

• Scale custom marker on map based on zoom level

      try {
          boolean success = mMap.setMapStyle(MapStyleOptions.loadRawResourceStyle(getContext(), R.raw.style_json));
          if (!success) {
              Log.e("MapsActivityRaw", "Style parsing failed.");
          }
  
      } catch (Resources.NotFoundException e) {
          Log.e("MapsActivityRaw", "Can't find style.", e);
      }
  
      final LatLng myLatlng = new LatLng(-33.999564, 18.516763);
      mMap.moveCamera(CameraUpdateFactory.newLatLng(myLatlng));
      mMap.animateCamera( CameraUpdateFactory.zoomTo( 11.0f ) );
  
      mMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
          public void onMapLoaded() {
  
              bar.setVisibility(View.GONE);
              drawCircle(myLatlng);

  }
  
  private void drawCircle(LatLng point){
      CircleOptions circleOptions = new CircleOptions();
      circleOptions.center(point);
      circleOptions.radius(500);
      circleOptions.strokeColor(Color.BLACK);
      circleOptions.fillColor(0x30ff0000);
      circleOptions.strokeWidth(2);
      mMap.addCircle(circleOptions);
  
  }
  

  This works perfectly, a circle is drawn to the map as expected.

  

  The problem is that when I zoom in and out the size of the circle increases/decreases.

  My Question:

  I'm looking for a way to keep the size of the circle the same when zooming in and out.

  Also..

  I don't want to use marker clustering.

• Where to find the list of markers available using the Google Maps API

  In the documentation section for Google Maps API, this page describes how put one of googles markers in your map. It seems the icon's url is https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png which lead me to look higher up in that hierarchy for other markers. I am, however, only getting 404s when I do and can't seem to find any answers online as to where I can find what other markers are available.

• SWIFT add GMSMarker to GMSMapView from a UICollectionViewCell

  Using the Google Map SDK, I am trying to add markers to a map as a user scrolls through a uicollectionview that is inside a tableview, inside a view controller (see image). Everything works great, and the function below loads markers to the map when called from MapViewConroller. The problem is that calling the function from the Collection View Cell results in no markers being added. Does this have something to do with how I am accessing mapView?

• Creating a zone following a route using Google map iOS SDK

  For my current map based application, I need to have the following features on Google Map iOS SDK

  1. User will select a source and a destination.
  2. User will put a few turning points on the map to reach from source to destination.
  3. User will also provide a width in meter.
  4. Now using this turning points and width I need to create a zone as specified in the following hand made sketch.

  

  I tried to create a polygon using GMSMutablePath. User was also able to drag each marker and resize and reposition the zone.

  

  I have also tried to understand Create a hollow polygon but could not find out a way to generate encoded string to use in the following example code.

  let hydePark = "tpwmEkd|y[QVe@Pk@BsHe@mGc@iNaAKMaBIYIq@qAMo@Eo@@[Fe@DoALu@HUb@c@XUZS^ELGxOhAd@@ZB`@J^BhFRlBN\\BZ@`AFrATAJAR?rAE\\C~BIpD"
  let archibaldFountain = "tlvmEqq|y[NNCXSJQOB[TI"
  let reflectionPool = "bewmEwk|y[Dm@zAPEj@{AO"
  
  let polygon = GMSPolygon()
  polygon.path = GMSPath(fromEncodedPath: hydePark)
  polygon.holes = [GMSPath(fromEncodedPath: archibaldFountain)!, GMSPath(fromEncodedPath: reflectionPool)!] 
  

  In my exploration project, user was specifying the location coordinate, which I do not want. Rather user will just put the turning points on the maps and provide the width and the zone will be calculated automatically.

  If there is any existing functionality from GoogleMaps SDK to achieve that? Or I need to follow a complex geometric calculation to draw the zone?
• Convert GMSMapView coordinate to iPhone screen point(x,y)

  I have tried to covert the marker position latitude-longitude to iPhone screen x and y coordinate, but it gives me negative value sometimes.

  MapView is added in main view from storyboard. self.mapView.frame - It is equal to main view frame iPhone 8 plus simulator = (origin = (x = 0, y = 0), size = (width = 414, height = 736))

  Marker position : (latitude = 22.811061859130859, longitude = 70.862533569335938)

  CGPoint pointInScreen = [self.mapView.projection pointForCoordinate:marker.position];
  

  Returns value - (x = -38547.58203125, y = 7061.60107421875) Which is not screen point. My marker is visible on the screen.

  Can anyone suggest me the right way to find out the screen x,y coordinate based on the marker latitude-longitude position?
