如何在类别中创建UITableViewCell排列JSON对象
I want to like this, Please have a look
我有UITableViewCell，我创建了类别明智的JSON数据。我获取了所有的价值，但是如何在特定数组中安排类别，比如在两个不同的数组下的“business_details”一侧的第一类“汽车”。我想在UITableViewCell中安排类别。怎么可能，请帮忙。谢谢

答案 0 :(得分：1)
试试这个 -
使用其他数组获取全局数组NSMutableArray *arrayForBool;。在viewDidLoad()中分配此数组，即arrayForBool=[[NSMutableArray alloc]init];
现在在connectionDidFinishLoading之前添加这些代码行
[tableview reloadData] -
for (int i=0; i<[names count]; i++) {
[arrayForBool addObject:[NSNumber numberWithBool:NO]];
}
这是完整的代码 -
#import "ViewController.h"
#import "MemberTableViewCell.h"
#import "secondVC.h"
@interface ViewController ()
{
NSMutableData *response;
NSMutableArray *arrayForBool;
NSMutableArray *business_details_array;
NSMutableArray *names;
NSDictionary *passDict;
}
@end

现在在secondVC.h档案 -

@interface secondVC : UIViewController
@property(strong,nonatomic)NSDictionary *myPreviousVCDict;
@end
NSLog() viewDidLoad()中的这个词典。希望这会帮助你。使用此方法，您可以创建Section和expandable部分的自定义标题。
这是输出屏幕 -
storyBoard必须看起来像这样 -
这是member_details你想要的 -
