UITableViewCell存储在其他数组中

Question

我有一个数组（arrData）和UITableViewCell重载arrData。 arrData存储在对象的Web服务数组中。 UITableViewCell在两个标签和一个图像，标签和图像中由arrData加载数据。所以所有标签和图像都在同一个数组中重新加载，但我想重新加载每个标签和图像的不同数组。

的ViewController

#import "ViewController.h"
#import "MemberTableViewCell.h"
#import "member_details.h"

@interface ViewController ()
 {
NSArray *arrData;
 }

@end

@implementation ViewController

 - (void)viewDidLoad {
[super viewDidLoad];

[self.tabel_view setAllowsMultipleSelection:YES];

NSURLRequest *req=[[NSURLRequest alloc]initWithURL:[NSURL URLWithString:@"http://edutimeapp.com/toshow/chamber-of-commerc/ws/fetch_member.php"]];
response =[[NSMutableData alloc]init];
[NSURLConnection connectionWithRequest:req delegate:self];

 }

 -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
 {
[response appendData:data];
NSLog(@"error receving data %@",response);
}

   -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
   {

  }
 -(void)connectionDidFinishLoading:(NSURLConnection *)connection
    {

     NSError *error;

    NSLog(@"Error in receiving data %@",error);
    NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves  error:&error];
  NSLog(@"response data %@",json);

   NSArray *status = json[@"status"];
   arrData = status;
   [self.tabel_view reloadData];
    }


- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
  {
  NSArray<NSIndexPath *> *selectedRows = [tableView indexPathsForSelectedRows];
if (selectedRows && [selectedRows containsObject:indexPath]) {

    return 127.0; // Expanded height
}

return 50.0; // Normal height
 }


 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
 {
return 1;
 }
 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
return [arrData count];
 }



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

MemberTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ht"];
if (cell==nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"Cell" owner:self options:nil];
    cell = [nib objectAtIndex:0];
}



cell.name.text= [[arrData objectAtIndex:indexPath.row] valueForKey:@"business_category_name"];
cell.title.text= [[[[arrData objectAtIndex:indexPath.row] valueForKey:@"business_details"] objectAtIndex:0] valueForKey:@"name"];
cell.email.text=[[[[arrData objectAtIndex:indexPath.row] valueForKey:@"business_details"] objectAtIndex:0] valueForKey:@"email"];

cell.image_view.image  = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[[[[arrData objectAtIndex:indexPath.row]valueForKey:@"business_details"]objectAtIndex:0] valueForKey:@"img_url"]]]];

return  cell;

试试这段代码
