[UITableViewCell menuImage]：无法识别的选择器发送到实例0x10bb1e5e0

Question

我创建了一个单独的UITableViewCell并使用.xib文件设计它，它看起来像是

我UITableViewCell的头文件看起来像

@interface MenuTableViewCell : UITableViewCell
@property(nonatomic, weak) IBOutlet UIImageView *menuImage;
@property(nonatomic, weak) IBOutlet UILabel *menuLabel;
@end  

并且两个属性都已连接
我尝试在我的MenuViewController中使用它作为

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    MenuTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    cell.menuImage.image = [self getImageNameForRow:indexPath.row];
    cell.menuLabel.text = self.features[(NSUInteger) indexPath.row];

    return cell;
}

和

- (UIImage *)getImageNameForRow:(NSInteger)row {
    if (row == 0) {
        return [UIImage imageNamed:@"Transaction"];
    }
    if (row == 1) {
        return [UIImage imageNamed:@"Summary"];
    }
    return [UIImage imageNamed:@"Budget"];
}  

当我运行我的应用程序时，它会崩溃并在日志

上显示以下内容

我对iOS不熟悉并且无法理解错误消息，有人可以帮助我知道我做错了什么吗？

Answer 1

有2个问题。

1. 我正在注册UITableViewCell而不是MenuTableViewCell
2. 我没有注册我拥有的nib文件

按照以下方式进行更改后，再次开始工作。

[self.tableView registerNib:[UINib nibWithNibName:@"MenuTableViewCell" bundle:nil] forCellReuseIdentifier:CellIdentifier];

感谢您的所有答案，他们帮助了我很多！

Answer 2

在接口中声明一个imgearray，然后添加你的图像数组，下一个cellforatindexpath为UIImageView添加代码 yourcellname.yourimagename.image = [UIImage imagenamed：[yourimagearray objectAtIndexPath.row]];
