iphone - UITableViewCell 自动调整大小掩码问题

Question

我在 UITableViewCell 的 contentView 中有 3 个 UI 元素，需要在设备旋转时正确对齐。目前，我强制执行这些 UI 元素的框架，如下所示:

segmentedControl1.frame = CGRectMake(165, 15, 130, 40);
segmentedControl2.frame = CGRectMake(435, 15, 130, 40);
segmentedControl3.frame = CGRectMake(710, 15, 130, 40);

我想知道如何使用这些元素的 autoresizingMask 属性来使它们在设备从横向旋转到纵向时调整大小并且不相互重叠(默认为纵向，仅限 iPad)。我不想为每个方向都有自定义框架位置。

我尝试过这样的事情:

segmentedControl1.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;
segmentedControl2.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
segmentedControl3.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin;

但这似乎不起作用。这些元素全部重叠且布局不合理。

有什么建议吗？

这是表格 View 单元格当前在横向模式下的样子:

--------------------------------------------------------------------------
|    ============              ============             ============     |
|   | A   |  B   |            | A   |  B   |           | A   |  B   |    |
|    ============              ============             ============     |
--------------------------------------------------------------------------

这就是当设备旋转到纵向模式时我想要的:

-------------------------------------------------------
|    ============    ============    ============     |
|   | A   |  B   |  | A   |  B   |  | A   |  B   |    |
|    ============    ============    ============     |
-------------------------------------------------------

更新2这是我在 cellForRowAtIndexPath 中的代码，其中包含 @Wolfert 的建议

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) 
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    cell.contentView.autoresizingMask = UIViewAutoresizingFlexibleWidth;

    // Configure the cell...
    segmentedControl1.frame = CGRectMake(165, 15, 180, 40);
    segmentedControl1.tag = indexPath.row;
    segmentedControl1.autoresizingMask = UIViewAutoresizingFlexibleRightMargin;
    [cell.contentView addSubview:segmentedControl1];

    segmentedControl2.frame = CGRectMake(435, 15, 180, 40);
    segmentedControl2.tag = indexPath.row;
    segmentedControl2.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
    [cell.contentView addSubview:segmentedControl2];

    segmentedControl3.frame = CGRectMake(710, 15, 180, 40);
    segmentedControl3.tag = indexPath.row;
    segmentedControl3.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin;
    [cell.contentView addSubview:segmentedControl3];

    return cell;
}

这应该可以解决问题:

segmentedControl1.autoresizingMask =   UIViewAutoresizingFlexibleRightMargin;
segmentedControl2.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
segmentedControl3.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin;

请注意，他们的 super View 应该具有以下属性:

view.autoresizingMask = UIViewAutoresizingFlexibleWidth;
