- [UIViewController setSelectedRowTitle：]：無法識別的選擇發送到實例0x13fab360

Question

我想從一個表視圖單元傳遞數據到下一個UIViewController。我使用的導航器也，但是當我點擊單元格，然後把它給錯誤： -

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

我用它去下一個數據是我prepareForSegue代碼： -

-(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; 
    } 
}

Mantosh，你可以簡單地這樣做：

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

  靜態NSString * aStrIdentifier = @「cell」; UITableViewCell * aCell = [tableView dequeueReusableCellWithIdentifier：aStrIdentifier];

  UILabel *aLblPlaceName=(UILabel*)[aCell viewWithTag:1]; 
  aLblPlaceName.text=[NSString stringWithFormat:@"%@", [arrPlaces objectAtIndex:indexPath.row]]; 
  
  return aCell; 
  

  }

• （無效）的tableView：（UITableView的*）的tableView didSelectRowAtIndexPath方法：（NSIndexPath *）indexPath

  { strStoreValue = [NSString的stringWithFormat：@ 「％@」，[arrPlaces objectAtIndex：indexPath.row]]; [self performSegueWithIdentifier：@「detailViewSegue」sender：self]; }

• （無效）prepareForSegue：（UIStoryboardSegue *）賽格瑞發件人：（ID）發送方

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