ios - 我可以只对特定的单元格标识符执行 didSelectRowAtIndexPath 吗？

Question

我在表格 View 中使用了两个不同的自定义表格单元格。也就是说，我只希望 didSelectRowAtIndexPath 在例如自定义单元标识符 2 被点击时触发(而不是在自定义单元标识符 1 被点击时触发)。我该怎么办？请参阅下面的代码。现在，didSelectRowAtIndexPath 会在任一单元格被点击时触发...

- (void)viewDidLoad {
    [super viewDidLoad];


   static NSString *ChatTableIdentifier = @"ChatTableViewCell";
   static NSString *ChatTableIdentifier2 = @"SwapDetailTableViewCell";


    UINib *nib = [UINib nibWithNibName: ChatTableIdentifier bundle:nil];
    [self.tableView registerNib:nib forCellReuseIdentifier: ChatTableIdentifier];

    UINib *nib2 = [UINib nibWithNibName: ChatTableIdentifier2 bundle:nil];
    [self.tableView registerNib:nib2 forCellReuseIdentifier: ChatTableIdentifier2];

}
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        NSDictionary *data = self.messages[indexPath.row];

        id swaptime = data[@"swaptime"];
        if ([swaptime isKindOfClass:[NSString class]]) {

            static NSString *ChatTableIdentifier2 = @"SwapDetailTableViewCell";

            SwapDetailTableViewCell *cell = (SwapDetailTableViewCell *)[tableView dequeueReusableCellWithIdentifier:ChatTableIdentifier2 forIndexPath:indexPath];

            NSString *time = data[@"swaptime"];
            cell.startTime.text = time;

            NSString *timeEnd = data[@"endswaptime"];
            cell.endTime.text = timeEnd;

            return cell;
        } else {
            static NSString *ChatTableIdentifier = @"ChatTableViewCell";

            ChatTableViewCell *cell = (ChatTableViewCell *)[tableView dequeueReusableCellWithIdentifier:ChatTableIdentifier forIndexPath:indexPath];

            NSString *userName = data[@"name"];
            cell.sendingUser.text = userName;

            NSString *messageBody = data[@"body"];
            cell.messageDisplayed.text = messageBody;

            NSString *timeReceived = data[@"published at"];
            cell.timeStamp.text = timeReceived;

            return cell;
        }
    }


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


            SwapDetailsViewController *detailViewController = [[SwapDetailsViewController alloc]
                                                                initWithNibName:@"SwapDetailsViewController" bundle:nil];

            detailViewController.swapDetails = [self.messages objectAtIndex:indexPath.row];

          [self presentViewController:detailViewController animated:YES completion:nil];

        }

Answer 1

您可以在 didSelectRowAtIndexPath 中放置一个 if 条件，就像您在 cellForRowAtIndexPath 中放置的那样

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

        NSDictionary *data = self.messages[indexPath.row];

        id swaptime = data[@"swaptime"];

        //perform action based on this, and don't do anything in second case

        if ([swaptime isKindOfClass:[NSString class]])   

        //this indexPath will always contain cell of one kind

        }else{

         // this indexPath will contain second cell kind
        }
    }

或者你也可以这样做-

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

       // this will give you cell at the selected indexPath
       id cell = [tableView cellForRowAtIndexPath:indexPath]

       //perform action based on this, and don't do anything in second case
       if ([cell isKindOfClass:[SwapDetailTableViewCell class]])                    

       }else{

       }
}
