ios - didDeSelectRowAtIndexPath 没有在 objective-c 中被调用

Question

我是 iOS 新手，在选择和取消选择表格 View 单元格时遇到问题。对于取消选择，我使用了 didDeSelectRowAtIndexPath 但它没有被调用

我的代码是这样的

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell  *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }
    cell.textLabel.text=[NSString stringWithFormat:@"%@",[reportshortActivityarray objectAtIndex:indexPath.row]];

    if([Selectedarray containsObject:[reportshortActivityarray objectAtIndex:indexPath.row]])
    {
        [cell setAccessoryType:UITableViewCellAccessoryCheckmark];
    }
    else
    {
        [cell setAccessoryType:UITableViewCellAccessoryNone];
    }

    return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
     UITableViewCell *cell = [activitytable cellForRowAtIndexPath:indexPath];

    if(![Selectedarray containsObject:[reportshortActivityarray objectAtIndex:indexPath.row]]){
        [Selectedarray addObject:[reportshortActivityarray objectAtIndex:indexPath.row]];
        txtactivity.text = [Selectedarray componentsJoinedByString:@","];
        DefaultActivityString=txtactivity.text;
    }

    NSLog(@"Selected Value =%@",txtactivity.text);

    if(![SelectedIDarray containsObject:[reportidActivityarray objectAtIndex:indexPath.row]]){
        [SelectedIDarray addObject:[reportidActivityarray objectAtIndex:indexPath.row]];
        lblactivity.text = [SelectedIDarray componentsJoinedByString:@","];
    }

    NSLog(@"Selected Value =%@",lblactivity.text);

    if (cell.selected) {
        // ... Uncheck
        [activitytable deselectRowAtIndexPath:indexPath animated:YES];
    }


    [[activitytable cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark];
    activitytable.hidden=NO;
}

- (void)tableView:(UITableView *)tableView didDeSelectRowAtIndexPath:(NSIndexPath *)indexPath
{


    if([Selectedarray containsObject:[reportshortActivityarray objectAtIndex:indexPath.row]]){
        [Selectedarray removeObject:[reportshortActivityarray objectAtIndex:indexPath.row]];
        txtactivity.text = [Selectedarray componentsJoinedByString:@","];
    }

    if([SelectedIDarray containsObject:[reportidActivityarray objectAtIndex:indexPath.row]]){
        [SelectedIDarray removeObject:[reportidActivityarray objectAtIndex:indexPath.row]];
        lblactivity.text = [SelectedIDarray componentsJoinedByString:@","];
    }
    NSLog(@"Selected Value =%@",lblactivity.text);

    [[activitytable cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryNone];
    activitytable.hidden=NO;
}

我正在使用此代码来选择和取消选择它正确选择但不取消选择。



如图所示，我可以选择该行但无法取消选择它。

强烈建议使用代码完成。这会给你正确的拼写(大小写很重要!):
...didDeselect...
注意小写 小号 选
