iphone - 向 UITableViewCell 添加 subview

Question

我在向 UITableViewCell 添加 subview 时遇到了问题。它在表格尺寸小于 iPhone 尺寸时有效。

但是当尺寸更大时，当我滚动时它会产生一些可怕的效果:

应该是这样的:

那么我认为它来自于细胞复用。这是我的代码示例:

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

    static NSString *kCellIdentifier = @"UITableViewCellStyleSubtitle";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
    if (cell == nil) {
        //construct the cell
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle 
                                       reuseIdentifier:kCellIdentifier] autorelease]; 


        //clear the previuous content
        NSLog(@"Il y a %d subviews", [[[cell contentView] subviews] count]);
        //[[[cell contentView] subviews] makeObjectsPerformSelector: @selector(removeFromSuperview)];
        NSLog(@"Il y a %d subviews", [[[cell contentView] subviews] count]);
        [[cell textLabel] setBackgroundColor:[UIColor clearColor]];
        [cell setSelectionStyle:UITableViewCellEditingStyleNone];
    }    

    switch (indexPath.row) {
        case 0:
            [cell addSubview:titleEvent];
            break;
        case 1:
            //load the owner logo
            [cell addSubview:logoAsso];
            break;
        case 2:
            //StartDate
            [cell addSubview:clockImage];
            break;
        case 3:
            //EndDate
            [cell addSubview:clockEndImage]; 
            break;
        case 4:
            //Address
            [cell addSubview:adress];
            break;
        case 5:
            //map
            [cell addSubview:map];
            break;
        case 6:
            //header
            [Graphism configureSeparationCell:cell];
            break;
        case 7:
            //descritpion
            [cell addSubview:descriptionEvent];
            break;
        default:
            break;
    }
    return cell;
}

subview 是类的属性，在viewDidLoad方法中配置。如果您能告诉我我做错了什么，那将是一种解脱。

试试这段代码

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cellIdentifier"];

    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cellIdentifier"] autorelease];

    } else {
        UIView *subView = (UIView *)[cell.contentView viewWithTag:1];
        if ([subView superview]) {
             [subView removeFromSuperview];
        }
    }

    UIView *subView = [[UIView alloc] init];
    subView.tag = 1;
    [cell.contentView addSubview:subView];
    [subView release];

    return cell;
}
