Display JSON data in UITableView - iphone

Question

My app is loading some data thought JSON and everything is working fine, but when I try to display those data in my UITableView cell, nothing happens. My code is below:
Get Data(JSON):
-(void)fetchedData:(NSData *)responseData {
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSArray* latestLoans = [json objectForKey:#"loans"];
testeDictionary = [latestLoans objectAtIndex:0];
testeLabel.text = [NSString stringWithFormat:#"%#",[testeDictionary objectForKey:#"id"]];
testeString = [testeDictionary objectForKey:#"username"];
[miArray addObject:[NSDictionary dictionaryWithObjectsAndKeys:testeString,#"username",nil]];
}
UITableView :
-(UITableViewCell *)tableView:(UITableView *)myTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = (UITableViewCell *)[self.settingsTableView dequeueReusableCellWithIdentifier:#"CellD"];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CellD" owner:self options:nil];
cell = (UITableViewCell *)[nib objectAtIndex:0];
}
if ([indexPath row] == 0) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CellA" owner:self options:nil];
cell = (UITableViewCell *)[nib objectAtIndex:0];
NSDictionary *itemAtIndex = (NSDictionary *)[miArray objectAtIndex:indexPath.row];
UILabel *usernameString = (UILabel *)[cell viewWithTag:1];
usernameString.text = [itemAtIndex objectForKey:#"id"]; <== MUST DISPLAY JSON VALUE
}
return cell;
}
More clearly I need to display this [testeDictionary objectForKey:#"id"] on the usernameString.text?

Answer 1

You are not storing the id
[miArray addObject:[NSDictionary dictionaryWithObjectsAndKeys:testeString,#"username",nil]];
I suppose what you want to be doing is something like this
NSString *idString = [NSString stringWithFormat:#"%#", [testeDictionary objectForKey:#"id"]];
[miArray addObject:[NSDictionary dictionaryWithObjectsAndKeys:
testeString, #"username",
idString, #"id",
nil]];
EDIT (explanation)
In your method fetchedData: you extract the id and set the text of some label to the id.
testeLabel.text = [NSString stringWithFormat:#"%#",[testeDictionary objectForKey:#"id"]];
After that you forget about the id. You then proceed to extract the username and you create a dictionary containing only the username and add that dictionary to an array called miArray.
[miArray addObject:[NSDictionary dictionaryWithObjectsAndKeys:testeString,#"username",nil]];
Notice that you do not specify any key named "id".
Later, you fetch a dictionary from miArray. This dictionary is the one you created with only one key, i.e. "username". You tell it to get an object for the key "id", but since you never specified that key, you get a nil value.
Bottom line, try my solution.
