Question

我有viewView的tableView，tableView有两个原型单元格，第二个单元格有sno，date，amount 3个标签。我创建了TableViewCell类，并在此TableViewCell类中为这3个标签创建了3个出口。我从服务器获取数据，我想将这些数据分配给这3个标签。怎么样？

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;


}

}

Answer 1

 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; 
}

Answer 2

您需要更改tableview单元格的类

否则{

 TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"detailsTitle" forIndexPath:indexPath];
  cell.dateLabel.text = [self.dateArray objectAtIndex:indexPath.row];
// same 
  cell.amountLabel.text = [self.dateArray objectAtIndex:indexPath.row];

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

    return cell;

}

或更改序列

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"]];

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

使用此代码

self.dataTask = [self.urlSession dataTaskWithRequest:self.urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

            NSMutableDictionary *serverRes = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

        self.dateArray = [[NSMutableArray alloc]init];
        self.amountArray = [[NSMutableArray alloc]init];
         for (int i = 0; i < [[serverRes objectForKey:@"Data"] count]; i++) {
                    [self.dateArray addObject:[[[serverRes objectForKey:@"Data"] objectAtIndex:i] objectForKey:@"Date"]];
                    [self.amountArray addObject:[[[serverRes objectForKey:@"Data"] objectAtIndex:i] objectForKey:@"TotalAmount"]];
                }

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

        }];

如何将viewController中的数据分配给tableViewCell标签？
