Question

我看到一些应用程序已经＆lt;的东西＆gt;在表格视图单元格中。如果我按左或右括号，它们之间的某些内容（文本或图形）会发生变化。它用于设置菜单。我该怎么做？有代码吗？

Answer 1

您需要通过继承UITableViewCell并向单元格视图添加两个按钮来创建自定义tableview单元格。

Answer 2

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

{

static NSString *CellIdentifier = @"Cell";

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

UIImageView *imgView;   
UIImageView *imgView1; 
UILabel     *lblName;   
if(cell == nil)   
{
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero              reuseIdentifier:CellIdentifier] autorelease];

    imgView = [[UIImageView alloc] initWithFrame:(5,0,20,62)];
    [imgView setImage:[UIImage imageNamed:@"leftimg.png"]];
    imgView.tag = 55;
    [cell.contentView addSubview:imgView];
    [imgView release];

    lblName = [[UILabel alloc] initWithFrame:CGRectMake(30, 0, 100, 25)];
    lblName.tag = 77;
    [cell.contentView addSubview:lblName];
    [lblName release];

    imgView1 = [[UIImageView alloc] initWithFrame:(200,0,20,62)];
    [imgView1 setImage:[UIImage imageNamed:@"rightimg.png"]];
    imgView1.tag = 66;
    [cell.contentView addSubview:imgView1];
    [imgView1 release];
}  
else    
{  
    imgView = (id)[cell.contentView viewWithTag:55];  
    imgView1 = (id)[cell.contentView viewWithTag:66];  
    lblName = (id)[cell.contentView viewWithTag:77];  

}
lblName.text = @"your text";

return cell;

}
