Select all the cells in UITableView

Question

what would be the best method to select all the cells in the table(UITableView) when the user presses a button in the tool bar?

Answer 1

You can select a cell calling table view's selectRowAtIndexPath method:

[menuTable selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:UITableViewScrollPositionTop];

However you can't select multiple cells in a UITableView. If you want to show and process on/off state of cells you should use cell with accessory view with UITableViewCellAccessoryCheckmark type. (see docs for more details)

Answer 2

Haven't tried it myself, but try this:

In your button action, loop through the indexPath and call it:

for (i = 0; i < [tableView numberOfSections]; i++) {
    for (j = 0; j < [tableView numberOfRowsInSection:i]; j++) {
         indexPath.row = j;
         indexPath.section = i;
         [tableView selectRowAtIndexPath:indexPath animated:animated scrollPosition:scrollPosition];
    }
}
