Local Edit Delegate method

VIKRANTKRISHNA — Mon, 14 Apr 2014 19:01:02 GMT

Is there a delegate method equivalent to

-(void)featureLayer:(AGSFeatureLayer *)featureLayer operation:(NSOperation *)op didFeatureEditsWithResults:(AGSFeatureLayerEditResults *)editResults{

available for local geodatabase edits. To know when geodatabase feature table edits is successful?

Thanks,
Vikrant

The editing methods (saveFeature:error:, and deleteFeature:error:) on AGSGDBFeatureTable are synchronous. They block until the edit is complete and return an error by reference if a problem was encountered. Hence, there is no need for a delegate. Once these methods finish, you can assume the edit has been applied to the local geodatabase (open transactions notwithstanding).

Thanks for the answer Devesh.

I have two parcel layers, submitting info for feature on first layer copies feature into second layer, and feature needs to be deleted from first layer. If executing addFeature and deleteFeature one after another, will cause issues if any one of them get error out.

One way is to revert the operation in case of error, do you think this is my best option?

Thanks,

The API supports transactions through AGSGDBTransaction. You can use this to rollback one of the edits if the other one fails.
