iphone - UITableView 覆盖/隐藏图像？

Question

在此处输入图像描述

我想在images我的上方制作 2 tableView- 一个image在顶部，一个在视图底部。就像图片上的一样。我image在顶部成功了（当我滚动时tableView，它在图像下方滚动），但是，image底部的没有出现。我所做的是，我只是调整了的大小tableView并在顶部和底部缩短了它并添加了UIImageView's. 但在底部，没有image. 我也尝试在代码中做到这一点：

CGRect flagsFrame = CGRectMake(0, 460, 320, 11);

UIImageView *bottomFlags = [[UIImageView alloc]initWithFrame:flagsFrame];
bottomFlags.image = [UIImage imageNamed:@"flags_down"];

[self.view addSubview:bottomFlags];
[self.view bringSubviewToFront:bottomFlags];

但什么也没有发生。为什么没有图片？看起来像tableView覆盖图像或其他东西。

谢谢！

看过去recursiveDescription，我看到两个UIImageView大小为 320x11 的 s。一个是的兄弟UITableView：

<UIImageView: 0x12ea90; frame = (0 0; 320 11); autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x126aa0>>

此图像视图的原点位于 (0,0)，因此我推断它是顶部图像视图。它UITableView在输出中列在之后，这意味着它在堆叠顺序中位于 table view 的上方 - 它“更接近”用户的眼睛，并将绘制在 table view 的顶部。

另一个尺寸为 320x11 的图像视图被列为表视图的子视图：

<UIImageView: 0x100b70; frame = (0 5608; 320 11); opaque = NO; userInteractionEnabled = NO; layer = <CALayer: 0x141f60>>

所以在我看来，您将底部图像视图添加为表格视图的子视图，但您需要将其添加为表格视图的兄弟。您需要将其添加为表视图的超级视图的子视图。

如果您希望图像保持在表格顶部

如果您希望 UItableView 上的图像始终如一，则将 UITableView 和两个页眉/页脚视图作为同一 UIView 的子视图并将页眉/页脚视图放在前面。诀窍是关闭他们userInteraction的触摸通过他们到UITableView下面。

UIView *container = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,460)];
[container addSubview:tableView];
[container addSubview:headerView];
[container addSubview:footerView];

headerView.userInteractionEnabled = NO;
footerView.userInteractionEnabled = NO;

如果您希望图像随表格滚动

您应该在 UITableView 实例的顶部和底部使用tableHeaderView和设置 UIView。tableFooterView

it seem there is a little problem in this line:

bottomFlags.image = [UIImage imageNamed:@"flags_down"];

try to add an extension for the image's name (.png), otherwise the the image property will be nil and you won't see the image in your entire life.

iphone - UITableView 覆盖/隐藏图像？
