Updating and Deleting features while in offline mode

deleted-user-4bdbdJY7UQ_i — Wed, 29 Feb 2012 19:15:59 GMT

Hi,

I have been trying to customize the Online/Offline and UC sample apps, and I am stuck.

I have not been able to find any sample code or reference that would enable me to delete/update geometry/update attributes while the layer is offline. I am doing just fine with adding new features, though.

All the samples that allow updating/deleting capabilities seem to require that the feature layer is connected to the server. Am I missing something?

Thanks in advance!

Mark

I am replying to my own thread to try to clarify my question.

1) I would like to take a feature layer offline for editing. No problems doing this with the SDK.

2) While offline, I would like to add additional features to this feature layer. Again no problems doing this with the SDK.

3) If I make a mistake and want to delete the feature that I just added offline - I am not able to do this as far as I know while I am offline.

4) If I want to update geometry or attributes of an existing feature - I am not able to do this as far as I know while I am offline.

I would like to be able to do #3 and #4 if it is possible. If it is not possible with this version of the SDK, I need to know this so that I do
not spend anymore countless hours trying to make it work.

Mark,

#3 and #4, both are possible. When you are in Offline mode and add features they are getting added as a text to the text file. You can grab that text file and perform #3 and #4.

Thanks, Nimesh. There is hope! I have poured through the reference and cannot find anything on the text file storage. Would you be able to clue me in on how to call this file?

In the OnlineOfflineEditingSample look for writeAddedFeatures and readAddedFeatures methods in OnlineOfflineFeatureLayer.m code file.
