RESET button to uncheck tableview

Question

Can any one please tell a code for unchecking a entire check marks in uitableview using a button click?

Answer 1

Create an NSMutableArray in your tableView datasource class and in your cellForRowAtIndexPath method, add the checkboxes to the Array. (check for duplicate).

Then on button click, iterate the array and uncheck them.

Answer 2

In didSelectRowAtIndexPath :

if (![myMutableArray containsObject:indexPath]) {
    [myMutableArray addObject:indexPath]; 
}
else{
    [myMutableArray removeObject:indexPath];
}

[sampleTableView reloadData];

And in cellForRowAtIndexPath :

if ([myMutableArray containsObject:indexPath]) {
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else{
    cell.accessoryType = UITableViewCellAccessoryNone;
}

And when button clicked, in that method remove the objects from this array and reload your tableView:

[myMutableArray removeAllObjects];
[sampleTableView reloadData];
