在“UITableViewCell”类型的对象上找不到属性

Question

我有 2 个自定义 UITableViewCell，并且都有属性。 尽管NSLog(@"%@", cell.class) 表明两者都被正确创建，但我无法在tableView:cellForRowAtIndexPath: 上设置我的属性。

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

    if (indexPath.row != [self.realties count]) {
        cell = [tableView dequeueReusableCellWithIdentifier:RealtyCellIdentifier];

        NSLog(@"%@", cell.class);

        cell.realtyNameLabel.text = [[self.realties objectAtIndex:indexPath.row] adTitle];
        cell.realtyPriceLabel.text = [NSString stringWithFormat:@"R$%ld", [[self.realties objectAtIndex:indexPath.row] price]];
    }

    if (indexPath.row == [self.realties count]) {
        cell = [tableView dequeueReusableCellWithIdentifier:LoadMoreCellIdentifier];

        NSLog(@"%@", cell.class);
    }

    return cell;
}

@import UIKit;

@interface IGBRealtyCell : UITableViewCell

@property (weak, nonatomic) IBOutlet UIImageView *realtyImageView;
@property (weak, nonatomic) IBOutlet UILabel *realtyNameLabel;
@property (weak, nonatomic) IBOutlet UILabel *realtyPriceLabel;

@end

我错过了什么？

您使用的是UITableViewCell 而不是IGBRealtyCell。尝试将其转换为 IGBRealtyCell 变量。

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

    if (indexPath.row != [self.realties count]) {
        cell = [tableView dequeueReusableCellWithIdentifier:RealtyCellIdentifier];
        IGBRealtyCell *realtyCell = (IGBRealtyCell*)cell; 

        NSLog(@"%@", cell.class);

        realtyCell.realtyNameLabel.text = [[self.realties objectAtIndex:indexPath.row] adTitle];
        realtyCell.realtyPriceLabel.text = [NSString stringWithFormat:@"R$%ld",    [[self.realties objectAtIndex:indexPath.row] price]];
   }

    if (indexPath.row == [self.realties count]) {
        cell = [tableView dequeueReusableCellWithIdentifier:LoadMoreCellIdentifier];
        IGBRealtyCell *realtyCell = (IGBRealtyCell*)cell; 
        NSLog(@"%@", realtyCell.class);
    }

    return cell;
}
