Display selective data in UITableView from an array - ios

Question

I Have an NSMutableArray which is being displayed as
(
13002,
My Drive,
13006,
Testing1,
13007,
Testing123
)
In my NSLog
I want to populate my UITableView with just the names (My Drive, Testing1 & Testing123) and want to use the ID's as the subtitle.

Answer 1

use cell for row at indexpath method and number of rows method as below
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return array.count/2;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
int row = [indexPath row]*2;
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.font = [UIFont boldSystemFontOfSize:14];
}
cell.textLabel.text = [array objectAtIndex:row+1];
cell.detailTextLabel.text = [array objectAtIndex:row];
return cell;
}
your problem will solve...

Answer 2

NSmutableArray *element; //contains your array
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *cellIdentifier = #"MyCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellIdentifier];
element = [array objectAtIndex:indexPath.row];
cell.textLabel.text = element;
element = [array objectAtIndex:indexPath.row +1 ];
cell.subtitle.text = element;

Answer 3

Depending on your application, you might want to consider using a NSMutableDictionary instead of the array. This way, your data model will accurately represent the fact that those names are mapped to ids. You can use
NSArray *arrayOf Keys = [theDictionary allKeys];
to get an array of the keys in your dictionary, then do something like this:
cell.textLabel.text = [theDictionary objectForKey:[arrayOfKeys objectAtIndex:indexPath.row]];
cell.detailtextLabel.text = [arrayOfKeys objectAtIndex:indexPath.row];

You should also consider using the free Sensible TableView framework. You would just pass the array to the framework and it will automatically display it in the table view.
