获取UITableView的选定索引

Question

我想选择索引UITableView.我写了以下代码:

NSIndexPath *index = [NSIndexPath indexPathForRow:1 inSection:0];
[tableView scrollToRowAtIndexPath:index 
                 atScrollPosition:UITableViewScrollPositionTop 
                         animated:YES];

这总是适用于第一项.我想要选择索引indexPathForRow.

请帮忙.谢谢.

Answer 1

NSIndexPath *selectedIndexPath = [tableView indexPathForSelectedRow];

Answer 2

获取当前选定的行.如果您只有一个部分,可能会有所帮助.

- (NSUInteger)currentSellectedRowIndex
{
    NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow];
    if (selectedIndexPath) {
        return selectedIndexPath.row;
    }
    else {
        return NSNotFound;
    }
}

Answer 3

使用此代码

CGPoint location =[sender locationInView:self.tableView];
NSIndexPath *swipedIndexPath = [self.tableView indexPathForRowAtPoint:location];
UITableViewCell *swipedCell  = [self.tableView cellForRowAtIndexPath:swipedIndexPath];
NSIndexPath *indexPath = [self.tableView indexPathForCell:swipedCell];
