1. AGSSketchEditor has a "style" property which has a "feedbackLineSymbol" property. You can set that to whatever line symbol you want. It defaults to a dashed symbol. 2. You can save the resulting geometry, which will be a Polygon or Polyline as JSON. They support AGSJSONSerializable. From there you can store it in user defaults or however you want. And then re-hydrate the geometry from JSON later.

Yes - you can use the AGSSketchEditor with the creation mode of AGSSketchCreationModeFreehandPolyline or AGSSketchCreationModeFreehandPolygon. Here is a sample that is using vertex editing. But change the creation mode to one of the above (ie .freehandPolyline) and you can sketch lines on the map. arcgis-runtime-samples-ios/SketchViewController.swift at master · Esri/arcgis-runtime-samples-ios · GitHub

Make sure you hold a reference to the AGSGeodatabase object, even after you create the layers. If it gets dealloc'd then it will try to clean up itself and you could end up with some undefined behavior.

I just tested it and it sure is a bug. I will submit an issue.

I have not seen this and I'm surprised at this behavior. Are you sure that there isn't somehow a second mapView being displayed? Maybe one was added during viewDidAppear?

No, it is not in v100. Looks like it might make it into an update in the future, probably not the next one.

This is in the iOS forum. It would be best to ask this in the Android SDK forum to get an answer from the Android team. That being said, I will forward this question to some Android team members that I know so hopefully you will get some kind of response.

XCode compresses PNG files and makes them un-readable by our png library. In your target build settings - try setting "Compress PNG Files" to "NO". Then run your project again and it should work.

The user defaults doesn't take just any object. You have a few options. One option is that you can put the JSON Dictionary representation of the view point in the user defaults using the toJSON method. This is what I think you should do. Then when you pull it out of the user defaults, use the fromJSON. AGSViewpoint is AGSJSONSerializable and has the to/fromJSON methods.

When you go to open the second map with the tpk, you just need to use the same viewpoint you currently have. You just ask the mapView for the currentViewpoint, then when you open the second map you set the initial viewpoint of it to that previous viewpoint. // get current viewpoint let vp = mapView.currentViewpoint(with: .centerAndScale) // if you want to see the coordinates of it, you do that like so print("viewpoint scale: \(vp?.targetScale)") print("viewpoint center: \(vp?.targetGeometry as! AGSPoint)") let map2 = AGSMap() // add tpk layers, etc here // ... // ... // // when you open the second map set the initial viewpoint to the // viewpoint that you saved map2.initialViewpoint = vp // open second map mapView.map = map2‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This is an issue that I can log and we can look into. The good news is that in the meantime you can try this workaround below. This kicks off a request manually, telling the request to save the data to disk (instead of memory) and also to use the portal's credentials. You already have a portal and portal item, so you don't need those 2 lines. The rest should get you going. func fetchData(){ portal = AGSPortal.arcGISOnline(withLoginRequired: true) let pi = AGSPortalItem(portal: self.portal!, itemID: "c580e6bbaedc4c6e82b9c50fbe6b46fd") // get url for fetching data endpoint if let fetchDataURL = portal?.url?.appendingPathComponent("sharing/rest/content/items/\(pi.itemID)/data"){ // create an operation setting the remote resource as the portal (so that it will use the portal's credentials) let op = AGSRequestOperation(remoteResource: portal, url: fetchDataURL, queryParameters: nil) // set output file so that the data isn't stored in memory as it's downloaded op.outputFileURL = FileManager.default.temporaryDirectory.appendingPathComponent("myData.dat") // set completion handler op.registerListener(self){ result, error in if let error = error{ // download of data failed print("error occurred: \(error.localizedDescription)") } else if let outputFile = result as? URL{ // download is complete and file is saved to disk print("download complete: \(outputFile)") } } // add the operation to the shared queue so that it can start AGSOperationQueue.shared().addOperation(op) } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Brett, Nick Furness pointed out to me that you need to actually union the lines together first to get what you are looking for. Here is objective-c code to do what you need: @interface AGSPolyline (intersects) -(NSArray<AGSPoint*>*)intersectionWithLine:(AGSPolyline*)line2; @end @implementation AGSPolyline (intersects) -(NSArray<AGSPoint*>*)intersectionWithLine:(AGSPolyline*)line2{ NSMutableArray *points = [NSMutableArray array]; // first union the lines together AGSPolyline *lineUnion = (AGSPolyline*)[AGSGeometryEngine unionOfGeometry1:self geometry2:line2]; // now get the intersecting line of union'ed line and self AGSPolyline *line3 = (AGSPolyline*)[AGSGeometryEngine intersectionOfGeometry1:self geometry2:lineUnion]; double tolerance = 1e-10; for (AGSPart *part in line3.parts){ for (AGSPoint *point in part.points){ double distance = [AGSGeometryEngine distanceBetweenGeometry1:point geometry2:line2]; // if the point is on the passed-in line then add it to the return value if (distance < tolerance){ [points addObject:point]; } } } return [points copy]; } @end -(void)testLineIntersection{ AGSPolyline *lineAB = [AGSPolyline polylineWithPoints:@[AGSPointMakeWGS84(0, 0), AGSPointMakeWGS84(10, 10)]]; AGSPolyline *lineCD = [AGSPolyline polylineWithPoints:@[AGSPointMakeWGS84(0, 10), AGSPointMakeWGS84(10, 0)]]; NSArray *pointsE = [lineAB intersectionWithLine:lineCD]; NSLog(@"intersection points: %@", pointsE); } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Thanks to Nick Furness for pointing this out. He also provided the swift code, which I converted to objective-c.

Actually - you should get back a line when intersecting 2 lines. My first answer above is incorrect, I will remove it for clarity. Code should look something like this: -(void)lineIntersection{ AGSPolyline *lineAB = [AGSPolyline polylineWithPoints:@[AGSPointMakeWGS84(0, 0), AGSPointMakeWGS84(10, 10)]]; AGSPolyline *lineCD = [AGSPolyline polylineWithPoints:@[AGSPointMakeWGS84(0, 10), AGSPointMakeWGS84(10, 0), AGSPointMakeWGS84(5, 10), AGSPointMakeWGS84(0, 0), AGSPointMakeWGS84(10, 10)]]; AGSPolyline *lineE = (AGSPolyline*)[AGSGeometryEngine intersectionOfGeometry1:lineAB geometry2:lineCD]; NSLog(@"lineE: %@", lineE); }‍‍‍‍‍‍

It is fixed now in version 100.0.0, which was recently released in November.

SBJson was a third party library that has no longer been necessary the last few years now that Apple has shipped NSJSONSerialization. Objects that support AGSJSONSerializable have a toJSON method you can call. That will give you a JSON object (most likely an NSDictionary, but could be an NSArray). You can use that JSON object with NSJSONSerialization to get NSData: AGSObject -> NSDictionary -> NSJSONSerialization -> NSData You can also go the other way if you have NSData: NSData -> NSJSONSerialization -> NSDictionary -> AGSObject Here is sample code showing you how to do both: -(void)testJSONSerialization{ // Example 1: AGSPoint to NSData of JSON string... // AGSPoint *point = [AGSPoint pointWithX:34 y:-117 spatialReference:[AGSSpatialReference WGS84]]; id jsonObject = [point toJSON:nil]; NSData *data = [NSJSONSerialization dataWithJSONObject:jsonObject options:0 error:nil]; // do whatever you want with the NSData... // ... // ... // For example print out a json string: NSLog(@"the json string: %@", [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]); // Example 2: NSData of JSON String to AGSPoint // id jsonObject2 = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; AGSPoint *point2 = (AGSPoint*)[AGSPoint fromJSON:jsonObject2 error:nil]; // print out and test for equality NSLog(@"point1: %@", point); NSLog(@"point2: %@", point2); NSAssert([point isEqualToGeometry:point2], @"point comparison failed..."); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
