Question

我有字典结构，如下

{
    data =     {
        "parent_category_list" =         (
                        {
                "cat_master_id" = 127;
                "cat_name" = Accessories;
                "cul_name" = en;
                "culture_category_id" = 127;
                "local_id" = 283;
                "parent_id" = 0;
                "pms_id" = 127;
                slug = "accessories-1";
            },
                        {
                "cat_master_id" = 323;
                "cat_name" = "Acrylic Products";
                "cul_name" = en;
                "culture_category_id" = 323;
                "local_id" = 247;
                "parent_id" = 0;
                "pms_id" = 323;
                slug = "acrylic-products-1";
            },{
                "cat_master_id" = 252;
                "cat_name" = Coolers;
                child =                 (
                                        {
                        "cat_master_id" = 1200;
                        "cat_name" = "Drink Ware";
                        "cul_name" = en;
                        "culture_category_id" = 2031;
                        "local_id" = 284;
                        "parent_id" = 250;
                        "pms_id" = 1200;
                        slug = "drink-ware-1";
                    }
                );
}

我想在UITableView中安排上述词典，如果词典有子类别即。子字典然后单元格应该是可扩展的，或者如果没有子类别那么那应该是正常的单元格。哪个应该是可点击的。我该如何设置？

Answer 1

在这里，我将所有词典带入一个名为＆＃34; arr＆＃34;

arr=[data objectForKey:@"parent_category_list"];

并根据字典数据实现了UITableView委托方法didSelectRowAtIndexPath。如果字典有子类别我打印一个日志说＆＃34;单元格不可点击＆＃34;。对于正常的字典打印日志说＆＃34;单元格是可点击的＆＃34;。

检查以下代码：

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSDictionary *dictSubCat=[[arr objectAtIndex:indexPath.row] objectForKey:@"child"];

    if ([dictSubCat isKindOfClass:[NSNull class]] || dictSubCat==nil)
    {
        NSLog(@"cell is clickable");
    }
    else
    {
        NSLog(@"cell is not clickable");
    }


}

Answer 2

试试这个......

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath   *)indexPath
{
 if ([indexPath compare:self.expandedIndexPath] == NSOrderedSame)
{
    [tableView beginUpdates];
  // set initial height for row 
    self.expandedIndexPath = nil;
    [tableView endUpdates];

}
else
{
 self.expandedIndexPath = [NSIndexPath indexPathForRow:indexPath.row     inSection:indexPath.section];

    [tableView beginUpdates];

    if ([indexPath compare:self.expandedIndexPath] == NSOrderedSame)
    {
        self.expandedIndexPath = indexPath;

     if ([[[[data objectForKey:@"parent_category_list"]   objectAtIndex:indexPath.row] objectForKey:@"child"] count]==0)
        {
           // set here expanded height for row 
         // clickable....
        }

        else{
            // no clickable...
        }


    }

   else
   {
   self.expandedIndexPath = nil;
   }

 [tableView endUpdates];
}
}

在UITableView中创建可扩展的UITableView和普通的UITableviewCell
