UITableView - what row was selected?
提问by Ilya Suzdalnitski
I have a question - how can I get a number of row selected in a table? I am assigning it manually to a variable. The problem is that if a row was deselected, my variable still keeps the old value.
我有一个问题 - 如何在表中选择多行？我正在将它手动分配给一个变量。问题是，如果取消选择一行，我的变量仍然保留旧值。
What can I do about it? Is there a method in UITableView that returns a number of a currently selected row?
我该怎么办？UITableView 中是否有一个方法可以返回当前选定行的编号？
Thank you in advance, Ilya.
提前谢谢你，伊利亚。

If you haven't implemented a delegate (see nduplessis), UITableView also offers:
如果您尚未实现委托（请参阅 nduplessis），UITableView 还提供：
- (NSIndexPath *)indexPathForSelectedRow
回答by nduplessis
The UITableViewDelegate will call
UITableViewDelegate 将调用
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
when a row is selected. From this you can easily determine the row by using indexPath.section and indexPath.row
选择行时。由此，您可以使用 indexPath.section 和 indexPath.row 轻松确定行
