ios - UITableView 自定义 accessoryView 只出现在最后一个单元格中

Question

我正在尝试为 UITableView 使用自定义 accessoryView。作为 accessorView，我正在使用 UIImageView。我面临的问题是 accessoryView 只出现在 UITableView 的最后一行。

在 viewDidLoad 中我初始化了 UIImageView。

customAccessory = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 10, 15)];
customAccessory.image = [UIImage imageNamed:@"icon_right"];

在 cellForRowAtIndexPath 中，我这样做:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    MyDayCell *cell =(MyDayCell *)[self.tableView dequeueReusableCellWithIdentifier:@"MyDayCell"];
    if (cell == nil) {
        NSArray *cellArray = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil];
        cell = [cellArray objectAtIndex:0];
    }
    switch (indexPath.row) {
        case 0:
            cell.image.image = [UIImage imageNamed:@"icon_guide"];
            break;
        case 1:
            cell.image.image = [UIImage imageNamed:@"icon_media"];
            break;
        case 2:
            cell.image.image = [UIImage imageNamed:@"icon_lives"];
            break;
        case 3:
            cell.image.image = [UIImage imageNamed:@"icon_ask"];
            break;
        case 4:
            cell.image.image = [UIImage imageNamed:@"icon_k"];
            break;
        default:
            break;
    }
    cell.name.text = [dataSource objectAtIndex:indexPath.row];
    cell.accessoryView = customAccessory;
    return cell;
}

一个 View 只能有一个父 View 。当您将自定义 View 添加到第二个单元格时，它将从第一个单元格中删除。因此，为每个表格 View 单元格创建自定义附件 View 。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    MyDayCell *cell =(MyDayCell *)[self.tableView dequeueReusableCellWithIdentifier:@"MyDayCell"];
    if (cell == nil) {
        NSArray *cellArray = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil];
        cell = [cellArray objectAtIndex:0];
    }
    switch (indexPath.row) {
        case 0:
            cell.image.image = [UIImage imageNamed:@"icon_guide"];
            break;
        case 1:
            cell.image.image = [UIImage imageNamed:@"icon_media"];
            break;
        case 2:
            cell.image.image = [UIImage imageNamed:@"icon_lives"];
            break;
        case 3:
            cell.image.image = [UIImage imageNamed:@"icon_ask"];
            break;
        case 4:
            cell.image.image = [UIImage imageNamed:@"icon_k"];
            break;
        default:
            break;
    }
    cell.name.text = [dataSource objectAtIndex:indexPath.row];
    UIImageView *customAccessory = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 10, 15)];
    customAccessory.image = [UIImage imageNamed:@"icon_right"];
    cell.accessoryView = customAccessory;
    return cell;
}
