iOS tableView multiple selection

Question

Many of the ways and methods out there to select multiple rows is either deprecated or doesn't work.

I simply want to select multiple rows in didSelectRowAtIndexPath and save them into Array or NSUserDefault. This case I picked NSUserDefault but I am willing to change it to Array.

This is my code:

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

    NotificationsTableViewCell *cell = (NotificationsTableViewCell*)[tableView cellForRowAtIndexPath:indexPath];

    //set clicked icon after row selected
    cell.imgIcon.image=[UIImage imageNamed:@"select-icon"];

    //notification id for selected row
    Notifications* selected = notifications[indexPath.section];
    selectedGroup = selected.NotificationsId;

     //save it in nsuserdefaults
    [[NSUserDefaults standardUserDefaults] setObject:selectedGroup forKey:@"notificationSelectedID"];

}

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

//deselect the row

}

Note: I am using latest Xcode SDK 8.

Thank you for your helps.

Answer 1

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

NotificationsTableViewCell *cell = (NotificationsTableViewCell*)[tableView cellForRowAtIndexPath:indexPath];

 // do your logic with following condition

if (cell.accessoryType == UITableViewCellAccessoryNone) 
    {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;

    } 
    else 
    {

        cell.accessoryType = UITableViewCellAccessoryNone;

    }

}

You can declare mutable array and when every time user selects particular row, add required detail for particular row in an array then use NSUserDefaults to store updated array.

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

[arrRows addObject:[NSString stringWithFormat:@"%@", indexPath]];
[[NSUserDefaults standardUserDefaults] setValue:arrRows forKey:@"arrRows"];

}
