How can you get the selected rows from a UITableView?
提问by Pittfall
So I've written this code to put a checkmark beside a row that I want selected because I want multiple selected rows
所以我写了这段代码，在我想要选择的行旁边打上一个复选标记，因为我想要多个选择的行
UITableViewCell *cell = [tableView cellForRowAtIndexPath:path];
if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
cell.accessoryType = UITableViewCellAccessoryNone;
} else {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
but when I use the method:
但是当我使用该方法时：
NSArray *selectedIndexPaths = [self.LightsView indexPathsForSelectedRows];
it only gets the last row that I clicked on. Is the checkmark not selecting it?
它只获取我点击的最后一行。复选标记没有选中它吗？

For the indexPathsForSelectedRows:method to work properly, you have to configure the table view to allow multiple selection of cells:
为了使该indexPathsForSelectedRows:方法正常工作，您必须配置表格视图以允许多选单元格：
tableView.allowsMultipleSelection = YES;
