自定义UITableViewCell上的delete按钮

1.通过UITableViewDelegate方法可以实现删除 tableview中某一行 

//滑动删除

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

{   

    NSUInteger row = [indexPath row];

    [bookInforemoveObjectAtIndex:row];//bookInfo为当前table中显示的array

    [tableView deleteRowsAtIndexPaths:[NSArrayarrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationLeft];

}

此时删除按钮为Delete，如果想显示为“删除” 中文的话，则需要实现UITableViewDelegate中的- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath方

- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{      return @"删除";  }  

或者，最简单的方式，将plist中的Localization native development region改为China即可

2.这只是让默认的Delete按钮显示成了中文的删除按钮而已，如果想将这个删除按钮换成其他图片形式的，怎么办呢？

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath  {      static NSString *RootViewControllerCell = @"RootViewControllerCell";      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:RootViewControllerCell];      if(cell == nil)      {          cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:RootViewControllerCell]autorelease];                    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];          [button setBackgroundImage:[UIImage imageNamed:@"delete.png"] forState:UIControlStateNormal];          [button setFrame:CGRectMake(280, 10, 30, 30)];          [button addTarget:self action:@selector(del:) forControlEvents:UIControlEventTouchUpInside];          [cell.contentView addSubview:button];             }            cell.textLabel.text = [array objectAtIndex:[indexPath row]];      cell.tag = [indexPath row];            NSArray *subviews = [cell.contentView subviews];      for(id view in subviews)      {          if([view isKindOfClass:[UIButton class]])          {              [view setTag:[indexPath row]];              [cell.contentView bringSubviewToFront:view];          }      }      return cell;  }    -(void)del:(UIButton *)button  {      NSArray *visiblecells = [self.table visibleCells];      for(UITableViewCell *cell in visiblecells)      {          if(cell.tag == button.tag)          {              [array removeObjectAtIndex:[cell tag]];              [table reloadData];              break;          }      }  }  

效果如下：
