Unable to retrieve updatedAt or createdAt values from Parse objects
ios, objective-c, parse-platform
Solution
Silly Matt. I think about this for a day then realise my mistake minutes after i post it.
updatedAt is a property on all PFObjects, no need to retrieve it using a key.
Given a PFObject named object...
NSDate *updated = [object updatedAt];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"EEE, MMM d, h:mm a"];
cell.detailTextLabel.text = [NSString stringWithFormat:@"Lasted Updated: %@", [dateFormat stringFromDate:updated]];
@Parse , tip of the hat
Problem
I'm an experienced Android developer trying to get a prototype iOS app running using the Parse service and sdk (https://www.parse.com/). It's great, and i can get all my objects and their values with no trouble, everything works fine. However, i cannot get the updatedAt value automatically created by Parse for each object. It's a must for me, and I dont want to have to save an aditional timestamp as a String when the data is sitting right there. This is the gist of what i was doing. ``` - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; } // this works fine cell.textLabel.text = [object objectForKey:@"name"]; //substring however does not NSDate *updated = [object objectForKey:@"updatedAt"]; NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; [dateFormat setDateFormat:@"EEE, MMM d, h:mm a"]; cell.detailTextLabel.text = [NSString stringWithFormat:@"Lasted Updated: %@", [dateFormat stringFromDate:update]]; //i also tried like this at first cell.detailTextLabel.text = [NSString stringWithFormat:@"Lasted Updated: %@", [object objectForKey:@"updatedAt"]]; return cell; ``` }
