Add a field to each object inside an array - ios

Question

I'm parsing XML data of a third party provider.
They include all the information i need for each Team, except their logo.
I have all the logos imported into my project.
Is there a way to add a logo field to each team?
This is my parse method, works perfectly
-(void) parseXML{
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"apikeygoeshere"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *xmlString = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSDictionary *xml = [NSDictionary dictionaryWithXMLString:xmlString];
NSMutableArray *items = [xml objectForKey:#"TeamLeagueStanding"];
NSString *nullentry = #""; // custom code for specific reason
NSString *nullentry2 = #""; // custom code for a specific reason
[items insertObject:nullentry atIndex:0]; // custom code for a specific reason
[items insertObject:nullentry2 atIndex:1]; // custom code for a specific reason
[self setTableData:items];
}
This is my cellForRowAtIndexPath method, as you will see my logos are being feed from an array that i have inside my code, but if the team that is in 1st place drops to 2nd, the logos won't change position
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"StandingsIdent";
StandingsViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSDictionary *item = [tableData objectAtIndex:[indexPath row]];
if ([item isKindOfClass:[NSDictionary class]]) {
long row = [indexPath row];
cell.cellTeamName.text = [item objectForKey:#"Team"];;
cell.cellTeamLogo.image = [UIImage imageNamed:_teamLogos[row]];
cell.cellTeamPosition.text = _teamPosition[row];
cell.cellPlayed.text = [item objectForKey:#"Played"];
cell.cellWins.text = [item objectForKey:#"Won"];
cell.cellTies.text = [item objectForKey:#"Draw"];
cell.cellLoses.text = [item objectForKey:#"Lost"]; ;
cell.cellPoints.text = [item objectForKey:#"Points"];
cell.cellInfo.text = _infoLeague[row];
}
else {
}
}
Is it possible to somehow add these logos to each team? so when team "x" moves the logo does too.
Here is the xml data structure after being parsed:
{
Draw = 10;
"Goal_Difference" = "-17";
"Goals_Against" = 39;
"Goals_For" = 22;
Lost = 11;
NumberOfShots = 395;
Played = 25;
PlayedAtHome = 13;
PlayedAway = 12;
Points = 22;
RedCards = 5;
Team = Partick;
"Team_Id" = 561;
Won = 4;
YellowCards = 41;
}
Thanks ;)

You receive an NSDictionaryfor each team - this is an immutable object so you can't change it. But, you can create a mutable copy of it (so you will have an NSMutableDictionary).
When you do:
NSMutableArray *items = [xml objectForKey:#"TeamLeagueStanding"];
it's unlikely that you actually get a mutable array back (though you might). Again though, you can create a mutable copy if not.
Then, iterate through the teams, create a mutable copy of the dictionary, add the key/value pair that you need for the logo and then replace the original entry in the array with your updated copy.
Or, an alternate approach:
Store your logos in a different dictionary, where the keys are the team names (or unique ids) and the values are the logo image names. Then, instead of _teamLogos[row] you would use _teamLogos[[item objectForKey:#"Team"]] to get the image name.
