The underlying map problem

雪原高1027

Hello. In the previous project, I used the framework version 10.2.4, and the map displayed was in Chinese style. Now after migrating to the latest version, the map displayed now becomes full English annotation, which is different from the map display of the old version, as shown in the picture I uploaded. Could you tell me how to display the map in Chinese?

Hi,

We are aware of this question and will provide a more detailed answer soon. Meanwhile, you can...

Check out a list of available 中文简体 basemaps provided by Esri here: https://www.arcgis.com/home/group.html?id=791e79050e574514ab4ef65df73528eb#overview (and explore them on ArcGIS Online in the web browser if you like)
Try out the street style of OpenStreetMap basemap, i.e. AGSMap(basemapStyle: .osmStreets) to see if it fits your needs

Thanks

Thank you for your reply. And then, I have another question. When I move or zoom the map, I was in "viewpointChangedHandler callback method to derive the self. The mapView. VisibleArea. Among other. Center. X", access to the coordinates of the inaccurate, and the actual coordinates deviation is very large. As is shown in

Hi,

Personally I never worked with mapping and positioning solutions for mainland China, but I've heard about the GCJ-02 coordinate system issue. See a few discussions below

Not sure if this is related to your problem, but it's worth a look. It hasn't been long since I joined Esri, so unfortunately I don't know if the coordinate system conversion is an issue or not in the Runtime. Did it work in 10.x version of Runtime?

Also, you may find it useful checking out GeoScene, the zh-cn localized version of Runtime provided by Esri's China subsidiary 易智瑞, as well as their support page.

https://www.geoscene.cn/support-30.html

They should be more acquainted with these China-specific issues and may provide help.

Hope it helps!

@MiaogengZhang Sorry to call you out of the blue. Do you happen to know sth about this issue? Thanks.

Hello, SORRY for replying to your message so late. First, this case works fine on 10.x. Then I found the method of converting GCJ-02 coordinates on the Internet, and there was still a big deviation after conversion. To be sure, latitude and longitude is indeed in the self. The mapView. ViewpointChangedHandler get in this method, I'm not sure where is the problem really appear, request your help.
