自定义UITableView中Delete操作的按钮

以前写过一篇文章：修改UITableView中Delete操作的默认按钮，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？

 

看一下下面的实现。

 

-(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;
		}
	}
}
