将子视图添加到UITableViewCell [英] add subviews to UITableViewCell

问题描述

将子视图添加到UITableViewCell时遇到问题。
当桌面尺寸低于iPhone尺寸时，它正在工作。

I have trouble when I add subviews to UITableViewCell. It's working when the table size is below the iPhone size.

但是当尺寸较大时，当我滚动时会产生一些像这样的可怕效果：

But when the size is bigger, it makes some horrible effect like this when I'm scrolling :

它应该是这样的：

然后我认为它来自细胞重用。
以下是我的代码示例：

Then I think it comes from the cell reuse. Here is a sample of my code :

- (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;
}

子视图是类的属性，并在方法viewDidLoad中配置。
如果你能告诉我我做错了什么，那将是一种解脱。

The subviews are attributs of the class, and configured in the method viewDidLoad. If you can tell me what i'm doing wrong, that would be such a relief.

推荐答案

switch (indexPath.row) {
    case 0:


        if (![cell.contentView viewWithTag:11]) {

            titleEvent.tag = 11;

            [cell.contentView addSubview:titleEvent];
        }


        break;
    case 1:
        if (![cell.contentView viewWithTag:11]) {

            logoAsso.tag = 11;

            [cell.contentView addSubview:logoAsso];
        }

像这样适用于所有开关案例

like this do for all switch cases
