Objective C - Problem with NSMutableArray and NSTableView - iphone

Question

I have a class named Person and in this class is the property PersonName (amongst others).
A MutableArray MyUserInfoArr contains many Person objects.
I want to list each PersonName in a Cell of a TableView? How do I do this?
Thanks in advance.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
Person *myPerson;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
NSString *cellValue = [myUserInfoArr objectAtIndex:indexPath.row];
cell.text = cellValue;
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
Person *myPerson = [myUserInfoArr objectAtIndex:indexPath.row];
cell.textLabel.text = myPerson.DisplayName;
NSLog(#"abc %i",indexPath.section);
}
This is my code, it ran, but it just return the attribute Person.DisplayName of the last object Person in the myUserInfoArr. How to fix it?

Answer 1

The easiest way would be to just set the text with:
Person *person = [MyUserInfoArr objectAtIndex:[indexPath indexAtPosition:1]];
cell.textLabel.text = person.PersonName;
indexPath contains two indexes, first is the section index, the 2nd is the item's index within the section. So I'm assuming in your case you have a single section, that's why there is nothing to do with the indexAtPosition:0.
You also have to set up the table's data source methods, these tell your table view how many sections/rows it should show:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [MyUserInfoArr count];
}

Answer 2

Person *person = [myUserInfoArr objectAtIndex:indexPath.row];
cell.textLabel.text = person.PersonName;
The reason your code doesn't work: the text property needs to be an NSString *, not a Person *.
