zoomTo methods of AGSMapView don't work if animated is set to NO

JimDabrowski

Whenever I try to use one of the zoomTo methods on my AGSMapView, if I set the animated property to NO, the map fails to zoom to the provided envelope, scale, factor, etc. If I set the animated property to YES, it works just fine. Any thoughts as to what I could be doing wrong or is this normal behavior for the AGSMapView on iOS?

I tested the following code and it works for both animated true and false.

AGSTiledMapServiceLayer *tiledLayer = [[AGSTiledMapServiceLayer alloc] initWithURL:[NSURL URLWithString:@"http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"]];

[self.mapView addMapLayer:tiledLayer withName:@Tiled Layer];

[self.mapView zoomToEnvelope:[[AGSEnvelope alloc]initWithXmin:-14225623 ymin:3997718 xmax:-12139951 ymax:5041807 spatialReference:[[AGSSpatialReference alloc] initWithWKID:102100] ] animated:false];

Is there anything different in your code?

JimDabrowski

Thanks for replying. My code is different in detail but not in concept.

I instantiate and load all my map layers (11 total, 5 feature layers from our own ags server and 6 graphics layers), then in the mapViewDidLoad delegate method I decide which point to center and zoom on (depends on what type of thing is being viewed in my program), create an AGSPoint object out of pre-saved coordinates and then call zoomToScale:withCenterPoint:animated.

At this point, if the animated property is set to NO, the map will not zoom to the given point and oftentimes ends up at (0,0), or sometimes stops somewhere in northern Canada. If I set the animated property to YES, it always works just fine. I've tried other zoomTo methods and the result tends to be the same.

I will probably try to create a separate app and try to replicate and narrow down what is happening. Perhaps what I described above will give you some additional insight into my particular problem.

Thanks for helping out.

Thank you for providing additional information. From what you described, I think maybe check spacial reference of your basemap, layers and the point. You can also post your simplified code here so that I can get a better idea of what happened.

Jim,

Please make sure the map has been loaded before calling the zoom method. Have you tried the simple sample at Esri/arcgis-runtime-samples-ios · GitHub ?

Hope this helps

Cheers

Thanks for the advice. I do check mapView.loaded before doing any of these things.
