ios - 如何将数据从 viewController 分配给 tableViewCell 标签？

Question

我有带 tableView 的 viewController，tableView 有两个原型(prototype)单元格，第二个单元格有 sno、date、amount 3 个标签。我创建了 TableViewCell 类，并为此 TableViewCell 类中的这 3 个标签创建了 3 个导出。我正在从服务器获取数据，我想将该数据分配给这 3 个标签。如何？

在tableViewCell.h中

@property (weak, nonatomic) IBOutlet UILabel *serialNumber;
@property (weak, nonatomic) IBOutlet UILabel *dateLabel;
@property (weak, nonatomic) IBOutlet UILabel *amountLabel;

在viewController.m中

- (void)viewDidLoad {
[super viewDidLoad];

self.displayDataTableView.delegate = self;
self.displayDataTableView.dataSource = self;

self.urlSession = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
self.urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://"]];
self.dataTask = [self.urlSession dataTaskWithRequest:self.urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

    NSMutableDictionary *serverRes = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
    //        NSLog(@"...%@ ", serverRes);

    self.integer = [[serverRes objectForKey:@"Data"] count];

    dispatch_async(dispatch_get_main_queue(), ^{
        [self.displayDataTableView reloadData];
    });

self.dateArray = [[NSMutableArray alloc]init];
self.amountArray = [[NSMutableArray alloc]init];
[self.dateArray addObject:[[[serverRes objectForKey:@"Data"] objectAtIndex:i] objectForKey:@"Date"]];
[self.amountArray addObject:[[[serverRes objectForKey:@"Data"] objectAtIndex:i] objectForKey:@"TotalAmount"]];

}


}];

[self.dataTask resume];

}

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


if(indexPath.row == 0)
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"detailsCell" forIndexPath:indexPath];

    return cell;
}else{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"detailsTitle" forIndexPath:indexPath];
   TableViewCell *tvc;
    tvc.dateLabel.text = [self.dateArray objectAtIndex:indexPath.row];

    NSLog(@"********** = %@", tvc.dateLabel.text);

    return cell;


}

}

 dispatch_async(dispatch_get_main_queue(), ^{
    [self.displayDataTableView reloadData];
});

 - (UITableViewCell *)tableView:(UITableView *)tableView    cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
 if(indexPath.row == 0)
{

 static NSString *cellIdentifier =@"detailsCell";
// Make Your cell as this
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier]; 
if (cell == nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];

 }
 cell.dateLabel.text = [self.dateArray objectAtIndex:indexPath.row];
 cell.amountLabel.text = [self.amountArray objectAtIndex:indexPath.row];

}
return cell; 
}
