Question

I am in a need for someone to help me out on switching custom cells when selected using didSelectRowAtIndexPath, so the idea is to have custom cell1 set as a state and when the user selects it this will disappear and cell2 will fade in which shows the capital of that state but other cells will remain as cell1 (or states) except the one which was selected.

This is how I’d do it…

tableView.h:

#import <UIKit/UIKit.h>
@interface tableView : UITableViewController {
    NSMutableArray *tableArray;
}

- (void)changeTitleAtIndexPath:(NSIndexPath *)indexPath;

@end

tableview.m (add these methods) :

in -(void)viewDidLoad add:

    tableArray = [[NSMutableArray alloc] init];
    [tableArray addObject:[NSMutableArray arrayWithObjects:[NSNumber numberWithBool:NO],@"City1",@"Capital1",nil]];
    [tableArray addObject:[NSMutableArray arrayWithObjects:[NSNumber numberWithBool:NO],@"City2",@"Capital2",nil]];
    [tableArray addObject:[NSMutableArray arrayWithObjects:[NSNumber numberWithBool:NO],@"City3",@"Capital3",nil]];
    [tableArray addObject:[NSMutableArray arrayWithObjects:[NSNumber numberWithBool:NO],@"City4",@"Capital4",nil]];

change:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    if (![[[tableArray objectAtIndex:indexPath.row] objectAtIndex:0] boolValue]) {
        cell.textLabel.text = [[tableArray objectAtIndex:indexPath.row] objectAtIndex:1];
    }else {
        cell.textLabel.text = [[tableArray objectAtIndex:indexPath.row] objectAtIndex:2]; 
    }




    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    [self changeTitleAtIndexPath:indexPath];
    [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationTop];
}

add:

- (void)changeTitleAtIndexPath:(NSIndexPath *)indexPath{
    BOOL newBool = ![[[tableArray objectAtIndex:indexPath.row] objectAtIndex:0] boolValue];
    [[tableArray objectAtIndex:indexPath.row] replaceObjectAtIndex:0 withObject:[NSNumber numberWithBool:newBool]];
}
