how to code to select multiple row with check mark? - iphone

Question

I have taken UITableView. I want to use checkmark on row. When row is selected check mark should show there and when he selects check mark row then check mark should disappear.
I used following code.
In my code only I select multiple row but am able to disappear on same checkmark with selected row.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
//if (cell == nil) {
cell.selectionStyle=UITableViewCellSelectionStyleNone;
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.textLabel.text=[[gmailList objectAtIndex:indexPath.row]valueForKey:#"Name"];
if(cell.selected)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
// Configure the cell...
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Uncheck the previous checked row
UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
if(cell.selected)
{
cell.accessoryType = UITableViewCellAccessoryNone;
cell.selected=FALSE;
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
cell.selected=TRUE;
}
}

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath*)indexPath{
if ([tableView tag]==2){
self.clearCheckMark = false;
if ([tableView cellForRowAtIndexPath:indexPath].accessoryType ==UITableViewCellAccessoryCheckmark)
{
[tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryNone;
}
else
{
[tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;
}
self.index = [tableView indexPathsForSelectedRows];
}
return indexPath;}

Try this- You have to define a global NSMutableDict and use that dict as below
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
//if (cell == nil) {
cell.selectionStyle=UITableViewCellSelectionStyleNone;
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.textLabel.text=[[gmailList objectAtIndex:indexPath.row]valueForKey:#"Name"];
if([[dict objectForKey:[NSString stringWithFormat:"%d",indexPath.row]] isEqualToString:#"YES"])
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
// Configure the cell...
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Uncheck the previous checked row
UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
if(cell.selected)
{
cell.accessoryType = UITableViewCellAccessoryNone;
[[dict setObject:#"NO"]] forKey:[NSString stringWithFormat:"%d",indexPath.row];
cell.selected=FALSE;
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
cell.selected=TRUE;
[[dict setObject:#"YES"]] forKey:[NSString stringWithFormat:"%d",indexPath.row];
}
}

Set NSMutableDictionary with key like "isChecked" "YES" or "NO" using below method
- (void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
NSMutableDictionary *dic = [gmailList objectAtIndex:indexPath.row];
if([[dic valueForKey:#"isChecked"]boolValue])
{
cell.accessoryType = UITableViewCellAccessoryNone;
[dic setObject:#"NO" forKey:#"isChecked"];
cell.selected=FALSE;
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
[dic setObject:#"YES" forKey:#"isChecked"];
cell.selected=TRUE;
}
[self.tableView reloadData];
}
