In my iPhone aplication I have a list of custom objects. I need to create a json string from them. How I can implement this with SBJSON or iPhone sdk?
NSArray* eventsForUpload = [app.dataService.coreDataHelper fetchInstancesOf:@"Event" where:@"isForUpload" is:[NSNumber numberWithBool:YES]];
SBJsonWriter *writer = [[SBJsonWriter alloc] init];
NSString *actionLinksStr = [writer stringWithObject:eventsForUpload];
and i get empty result.
