static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];

Answer 1

In viewDidLoad add this array
dataArr=[[NSMutableArray alloc]initWithObjects:#"Hyderabad",#"Bangalore",#"Chennai",#"Pune",#"Mumbai", nil];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *reUseid=#"cellID";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:reUseid];
if (cell==nil)
{
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reUseid];
}
cell.textLabel.text = dataArr[indexPath.row];
return cell;
}
Here is TableView didSelectRowAtIndexPath method.
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"selected is %#",[dataArr objectAtIndex:indexPath.row]);
[self performSegueWithIdentifier:#"viewToDescriptionSegue" sender:self];
}
in this method you got indexpath from that you can get selected row like indexpath.row and from that you can get object from array.

Answer 2

There is a UITableViewDelegate method named didSelectRowAtIndexPath which get called up when user select any row. Get the value from your array at indexPath.row and set the text on your label.
Implement the below code on your project:-
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *name = [arrayname objectAtIndex:indexPath.row];
[yourLabelInstance setText:name];
}

Answer 3

This is a delegate method of UITableView which is called when you tap on cell.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
city.text = [arrayname objectAtIndex:indexPath.row];
}

Answer 4

Below is a delegate method of UITableView which is called when you touch/select any row in table.
Here, using indexPath parameter you can access currently selected row index. You can access data from datasource array having selected row index.
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *strCity = [arrCity objectAtIndex:indexPath.row];
[lblCity setText:strCity];
}
