【问题描述】：

我正在尝试将数据从一个表格视图单元传递到下一个 UIViewController。我也在使用导航控制器，但是当我单击单元格时，它会给出错误：-

-[UIViewController setSelectedRowTitle:]: unrecognized selector sent to instance 0x13fab360

我接下来使用的 prepareForSegue 代码是：-

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [NearBy_PlacesArray count];
}


-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *TableIdentifire = @"NearMe";

    NearByTableViewCell *cell = (NearByTableViewCell*)[self.tableView dequeueReusableCellWithIdentifier:TableIdentifire];

    if (cell == nil)
    {
        cell = [[NearByTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:TableIdentifire];

    }

    NearByPlace *nearBy = [NearBy_PlacesArray objectAtIndex:indexPath.row];

    cell.NearBy_Thumbnail_Image.image = [UIImage imageNamed:nearBy.NearByImageName];
    cell.NearBy_TitleLabel.text = nearBy.NearByPlaceName;
    cell.NearBy_NoLabel.text = nearBy.NearByPlace_no;


    return cell;
}
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"ShowNearByPlaces"])
    {


        NSIndexPath *indexPath = nil;
        NearByPlace *nearPlace = nil;

            indexPath = [self.tableView indexPathForSelectedRow];
            nearPlace = [NearBy_PlacesArray objectAtIndex:indexPath.row];

        NSLog(@"indexPath-- %@ \n" , indexPath);
        NSLog(@"recipe-- %@ \n " , nearPlace);


        nearByPlaceDetail_ViewController *destViewController = segue.destinationViewController;

        destViewController.SelectedRowTitle = nearPlace;
    }
}

【解决方案1】：

Mantosh，你可以这样做：

(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{ 静态 NSString *aStrIdentifier = @"cell"; UITableViewCell *aCell=[tableView dequeueReusableCellWithIdentifier:aStrIdentifier];
```
UILabel *aLblPlaceName=(UILabel*)[aCell viewWithTag:1];
aLblPlaceName.text=[NSString stringWithFormat:@"%@", [arrPlaces objectAtIndex:indexPath.row]];

return aCell;
```
}
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

{ strStoreValue = [NSString stringWithFormat:@"%@", [arrPlaces objectAtIndex:indexPath.row]]; [self performSegueWithIdentifier:@"detailViewSegue" sender:self]; }
(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

{ DetailViewController *aObjDetailVC = segue.destinationViewController; aObjDetailVC.strPlace = strStoreValue; }
