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：
