How to assign different z-order to my Interface Builder objects?
提问by aneuryzm
How can I change the z-value, or just send to back or to front the objects in Interface Builder?
如何更改 z 值，或者只是将 Interface Builder 中的对象发送到后面或前面？
i.e. I would like to move to front the "Label" in this View:
即我想在这个视图中移动到“标签”的前面：

You need to reorder then in Interface Builder. It seems like you're using Xcode 4. So, first, click on the arrow in the bottom left corner of IB to expand the side panel:
您需要在 Interface Builder 中重新排序。看起来您正在使用 Xcode 4。因此，首先，单击 IB 左下角的箭头以展开侧面板：
Next, click and drag the views that you'd like to rearrange.
接下来，单击并拖动要重新排列的视图。
The lower an item is on the list from the top of the list, the higher its "z-index".
项目在列表顶部的列表中越低，其“z-index”就越高。

I had the same problem when copying/pasting a background image view. I couldn't drag it to change its z-order in the Document Outline panel (in Interface Builder).
复制/粘贴背景图像视图时，我遇到了同样的问题。我无法在“文档大纲”面板（在界面生成器中）中拖动它来更改其 z 顺序。
The answer was just to restart xCode.
答案只是重新启动 xCode。
I think that re-indexed/re-built the storyboard and I could drag it higher in the list (thus making it lower in the z-order + behind the other controls).
我认为重新索引/重新构建故事板，我可以将它在列表中拖到更高的位置（从而使其在 z-order + 其他控件后面更低）。
