Ios 如何在按类别排列JSON对象中创建UITableViewCell

我有UITableViewCell，我创建了按类别排列的JSON数据。我获取了我们所有的值，但是如何在特定数组中安排类别，比如在两个不同数组下的“business_details”中的第一个类别“Automotive”。我想在UITableViewCell中排列类别。怎么可能，请帮忙。多谢各位

JSON 我的代码

NSLog（@“接收数据时出错%@”，错误）；
NSMutableDictionary*json=[NSJSONSerialization JSONObjectWithData:响应选项：NSJSONReadingMutableLeaves错误：&错误]；
NSLog（@“响应数据%@”，json）；
NSArray*状态=[json objectForKey:@“状态”]；
用于（NSDictionary*状态为状态）{
NSString*business_category=[状态值forkey:@“business_category_name”]；
[名称添加对象：业务类别]；
NSLog（@“业务详细信息%@”，名称）；
对于（NSDictionary*详细信息位于[status objectForKey:@“business_details”]）
{
NSString*name=[详细信息值forkey:@“name”]；
[ntm addObject:name]；
NSLog（@“名称%@”，ntm）；
NSString*地址=[详细信息值forkey:@“地址”]；
[adrsary addObject:address]；
NSLog（@“地址%@”，adrsary）；
NSString*phone=[详细信息值forkey:@“phone”]；
[phoneary addObject:phone]；
NSLog（@“phone%@”，phoneary）；
NSString*email=[详细信息值forkey:@“email”]；
[电子邮件地址对象：电子邮件]；
NSLog（@“email%@”，emailary）；
NSString*网站=[details valueForKey:@“网站”]；
[网站地址对象：网站]；
NSLog（@“网站%@”，网站）；
NSString*memsens=[详细信息值forkey:@“成员自”]；
[感官对象：memsens]；
NSLog（@“mem.sense%@”，sensary）；
NSString*des=[详细信息值forkey:@“des”]；
[desary addObject:des]；
NSLog（@“desc.%@”，desary）；
NSString*img=[详细信息值forkey:@“img_url”]；
[图像添加对象：img]；
NSLog（@“图像%@”，图像）；
}
}
对于（inti=0；i试试这个-

将全局数组，即
NSMutableArray*arrayforpool；
与其他数组一起使用。在
viewDidLoad（）
中分配此数组，即
arrayforpool=[[NSMutableArray alloc]init]；

现在在前面的
connectiondFinishLoading
中添加这些代码行
[tableview重新加载数据]
-

for (int i=0; i<[names count]; i++) {
        [arrayForBool addObject:[NSNumber numberWithBool:NO]];
    }

NSLog（）
在
viewDidLoad（）
中使用此词汇。希望这对您有所帮助。使用此功能，您可以自定义节头和可扩展节

这是输出屏幕-


故事板必须是这样的-


这是您想要的详细信息--

您可以通过将business_类别设置为tableview的一部分，并返回numberOfRows（每个部分的行数为business_details数组中的对象数）来实现这一点。这是可能的，但您的屏幕截图非常完美，即使用tableview标题进行更多编码和更少编码。tableview标题的高度是固定的。@Dev.RK我能做些什么，请提供帮助nk您想要可扩展的tableview？是指单击节头展开/折叠节。@BhadreshKathiriya这是android应用程序的屏幕截图，我想在I-phone应用程序中实现我使用了您的代码并运行项目仅显示标题“business\u category\u name”，然后单击任意一个“business\u category\u name”崩溃应用程序和错误显示如下：--[\u NSArrayM objectAtIndex:]：索引6越界[0..5]'你在吗，我卡住了，请帮助。成功运行，但在所有类别数据显示中只有一个类别标题。Dev.RK所有工作正常，单击标题并展开单元格只能按类别划分。请帮助我：（很抱歉回复得太晚，但我告诉过你请删除行单元格.name.text=[NSString stringWithFormat:@“%@”，[names objectAtIndex:indexPath.row]]；从cellforrowatindexpath方法检查新屏幕截图..我想你想要这个..我说的对吗？
