How to assign data from viewController to tableViewCell labels? - ios

Question

I have viewController with tableView, tableView has two prototype cells, second cell has sno, date, amount 3 labels. I created TableViewCell class and i created 3 outlets for this 3 labels in this TableViewCell class. I am getting data from server and i want to assign that data to this 3 labels. How?
In tableViewCell.h
#property (weak, nonatomic) IBOutlet UILabel *serialNumber;
#property (weak, nonatomic) IBOutlet UILabel *dateLabel;
#property (weak, nonatomic) IBOutlet UILabel *amountLabel;
In viewController.m
- (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

you need to change class of tableview cell
else{
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;
}
or change sequence
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];
});

Use this code
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];
});
}];
