TableView图像加载问题。（表格Cell的完整代码）

Question

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

  dictionary = [QuestionMutableArray objectAtIndex：0];

  static NSString * CellIdentifier = @“BeginingCell”;

  BeginingCell * cell =（BeginingCell *）[tableView dequeueReusableCellWithIdentifier：CellIdentifier];

  if（cell == nil）{

  NSArray *topLevelObjects=[[NSBundle mainBundle] loadNibNamed:@"BeginingCell" owner:self options:nil ];
  
  for(id CurrentObject in topLevelObjects)
  {
      if ([CurrentObject isKindOfClass:[BeginingCell class]]) {
  
          cell=(BeginingCell *) CurrentObject;
          break;
      }
  }
  

  }

  //配置单元格。

  如果（indexPath.row == 0） {

  cell.SectionTitle.text=[dictionary objectForKey:@"question"];
  cell.Option1.text=[dictionary objectForKey:@"option1"];
  cell.Option2.text=[dictionary objectForKey:@"option2"];
  cell.Option3.text=[dictionary objectForKey:@"option3"];
  cell.Option4.text=[dictionary objectForKey:@"option4"];
  
  
  UIImage *imgDef=[UIImage imageNamed:@"man_kirstie_alley.jpg"];
  [cell.myImageView setImage:imgDef];
  
  
  
  
  [MyTestArray release];
  
  [cell.button1 setTitle:@"A." forState:UIControlStateNormal];
  [cell.button2 setTitle:@"B." forState:UIControlStateNormal];
  [cell.button3 setTitle:@"C." forState:UIControlStateNormal];
  [cell.button4 setTitle:@"D." forState:UIControlStateNormal];
  

  }

  返回单元格;

}

我认为你必须先创建一个单元格。您可以使用这样的默认单元格：

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

static NSString *CellIdentifier = @"Cell";

//---try to get a reusable cell---

UITableViewCell *cell = [tableView
    dequeueReusableCellWithIdentifier:CellIdentifier];

//---create new cell if no reusable cell is available---
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
             reuseIdentifier:CellIdentifier] autorelease];
}

//---You would set the image here---
UIImage *imgDef=[UIImage imageNamed:@"man_kirstie_alley.jpg"];
cell.image = imgDef;

return cell;
