This can select all rows in the table view:

for (NSInteger s = 0; s < self.tableView.numberOfSections; s++) {
        for (NSInteger r = 0; r < [self.tableView numberOfRowsInSection:s]; r++) {
            [self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:r inSection:s]
                                        animated:NO
                                  scrollPosition:UITableViewScrollPositionNone];
        }
    }

Here is my method to traverse a table, it works well.

for (int i = 0; i < [ptableView numberOfSections]; i++) {
    for (int j = 0; j < [ptableView numberOfRowsInSection:i]; j++) {
        NSUInteger ints[2] = {i,j};
        NSIndexPath *indexPath = [NSIndexPath indexPathWithIndexes:ints length:2];
            UITableViewCell *cell = [ptableView cellForRowAtIndexPath:indexPath];
           //Here is your code

    }
}

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];
    }
}

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)
