UITableViewCell Accessory Type Checked on Tap & Set other unchecked

Question

Hello, Every one.

I am confused a little bit about settings table view cell accessories.

I have fixed two sections in my table

• Home
• Office

What I want is as follow....

• When User tap any of the cell
• Cell gets selected &
  • I want to set checked (set uitableviewcell accessory type -checked of tapped cell )
• And also all other cell's accessory type now should set to
  • uitable view cell accessory type none

I have tried following code. But I found that indexpath.row & indexpath.section is readonly properties.

// Override to support row selection in the table view.
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {    
    [tblProfileView deselectRowAtIndexPath:indexPath animated:YES];
    int i,max;
    UITableViewCell *x; NSIndexPath *tt;

    for(i=0;i<[tblProfileView numberOfRowsInSection:0];i++)
    {
     tt.row=i; tt.section=0;
     x=[tblProfileView cellForRowAtIndexPath:];
     [x setAccessoryType:UITableViewCellAccessoryNone];
    }
    for(i=0;i<[tblProfileView numberOfRowsInSection:1];i++)
    {
     tt.row=i; tt.section=1;
     x=[tblProfileView cellForRowAtIndexPath:tt];
     [x setAccessoryType:UITableViewCellAccessoryNone];
    }

    x=[tblProfileView cellForRowAtIndexPath:indexPath];
    [x setAccessoryType:UITableViewCellAccessoryCheckmark];
    // Navigation logic may go here -- for example, create and push another view controller.
    // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil];
    // [self.navigationController pushViewController:anotherViewController animated:YES];
    // [anotherViewController release];
}

I would keep track of the data that should be checked and change the cell in tableView:didSelectRowAtIndexPath: and update which data is checked in tableView:cellForRowAtIndexPath: like this:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    // do usual stuff here including getting the cell

    // determine the data from the IndexPath.row

    if (data == self.checkedData)
    {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    } else {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }

    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // determine the selected data from the IndexPath.row

    if (data != self.checkedData) {
       self.checkedData = data;
    }

    [tableView reloadData];
}
