UITableView覆盖/隐藏图像？
我希望在images之上设置2 tableView - 顶部一个image，视图底部一个image。就像在图片上。我在顶部tableView成功（当我滚动image时，它会在图片下滚动），但是，底部的tableView不会出现。
我做了什么，我只是调整了UIImageView's的大小并在顶部和底部缩短了它并添加了image。但在底部，没有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];
。我也尝试在代码中执行此操作：
tableView但没有任何反应。为什么没有图片？看起来<UIWindow: 0x1be340; frame = (0 0; 320 480); layer = <UIWindowLayer: 0x1be430>>

3 个答案:
答案 0 :(得分：1)
查看recursiveDescription，我看到两个大小为320x11的UIImageView。一个是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。它在输出中的UITableView之后列出，这意味着它在堆叠顺序中位于表视图之上 - 它“更接近”用户的眼睛，并将绘制在表视图的顶部。
大小为320x11的其他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>>
因此在我看来，您将底部图像视图添加为表视图的子视图，但您需要将其添加为表视图的同级。您需要将其添加为表视图的超级视图的子视图。
答案 1 :(得分：1)
如果您希望图像保持在表格顶部
如果您想要将图像一致地放在UItableView上，那么将UITableView和两个页眉/页脚视图放在同一个UIView的子视图中，并将页眉/页脚视图放在前面。诀窍是关闭他们的userInteraction触摸它们到下面的UITableView。
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;
如果您希望图像与表格一起滚动
您应该使用tableHeaderView和tableFooterView在UITableView实例的顶部和底部设置UIView。
答案 2 :(得分：0)
这一行似乎有点问题：
bottomFlags.image = [UIImage imageNamed:@"flags_down"];
尝试添加图片名称的扩展程序（.png），否则image属性将为nil，您将看不到你一生中的形象。
