使用多个自定义 UITableViewCells [英] Using multiple custom UITableViewCells

问题描述

我正在尝试实现像联系人应用程序详细视图这样的分组样式 UITableView.我希望最顶部的单元格是透明的，并在底部有一个 UISegemtedControl.

I´m trying to achieve a grouped styled UITableView like the Contact apps detailedView. I want the top most cell to be transparant and have a UISegemtedControl at the bottom.

当我尝试创建两种不同类型的自定义单元格时，即使我使用了两种不同的 cellIdentifier，也只会加载第一种.

When I try to create two different types of custom cells, only the first one is loaded even though i use two different cellIdentifiers.

希望得到一些指导.或者针对同一主题的一些不错的教程提示.

Would appreciate som guidance. Or some good tutorial tips for the same topic.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    /*
    UIView *backView = [[UIView alloc] initWithFrame:CGRectZero];
    backView.backgroundColor = [UIColor clearColor];
    cell.backgroundView = backView;
    [backView release];
    */

    static NSString *cellIdentifier1 = @"DetailCellStyle1";
    static NSString *cellIdentifier2 = @"DetailCellStyle2";

    if (indexPath.section == 0) {

        // Load from nib
        DetailCellViewController *cell = (DetailCellViewController *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier1];
        if (cell == nil) {
            NSArray *topLevelObjects = [[NSBundle mainBundle]
                                        loadNibNamed:@"DetailCellView" 
                                        owner:nil 
                                        options:nil];

            for (id currentObject in topLevelObjects) {
                if ([currentObject isKindOfClass:[UITableViewCell class]]) {
                    cell = (DetailCellViewController *) currentObject;
                    break;
                }
            }
        }

        return cell;
    }
    else  {
        // Load from nib
        DetailCellViewController2 *cell = (DetailCellViewController2 *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier2];
        if (cell == nil) {
            NSArray *topLevelObjects = [[NSBundle mainBundle]
                                        loadNibNamed:@"DetailCellView" 
                                        owner:nil 
                                        options:nil];

            for (id currentObject in topLevelObjects) {
                if ([currentObject isKindOfClass:[UITableViewCell class]]) {
                    cell = (DetailCellViewController2 *) currentObject;
                    break;
                }
            }
        }

        return cell;
    }

    return nil;
}

推荐答案

通过在 "DetailCellView" 笔尖中获取 UITableViewCell 类型的第一个对象，您以完全相同的方式加载单元格 1 和单元格 2.因此，您在两种情况下都会获得相同的单元格.

You load cell 1 and cell 2 in exactly the same way by taking the first object of type UITableViewCell in the "DetailCellView" nib. Therefore, you're getting the same cell in both cases.
