使用Interface Builder嵌套自定义类/ XIB [英] Nesting Custom Classes/XIB's with Interface Builder
问题描述
我会尽量做到尽可能短。
I'll try to make this as short as I can.
我写了一个自定义类，用一些IBOutlet属性扩展UIView，它有一个与这些IBOutlet链接的XIB相关联。
I wrote a custom class that extends UIView with a couple of IBOutlet properties, and it has a XIB associated with it where those IBOutlets are linked to.
然后，我想要获取该类，将其嵌入到其他一些XIB（例如，表格单元格）中，并且让它工作。
I then want to take that class, embed it in some other XIB (for example, a table cell), and just have it work.
似乎当我在新的XIB中嵌入该自定义类时，它无法识别与之关联的原始XIB，因此它要求我将IBOutlets重置为新XIB上的接口元素。这很蹩脚。
It seems that when I embed that custom class in the new XIB, it does not recognize the original XIB I associated with it, so it asks for me to reset the IBOutlets to interface elements on the new XIB. This is lame.
有没有人理解我想做什么并且有一个好方法？
Does anyone understand what I am trying to do and have a good approach?
推荐答案
以下是我设法完成这项工作的方法：
Here's how I managed to make this work:
在Interface Builder中
打开外部笔尖并执行以下操作：
In Interface Builder
Open your outer nib and do this:
- 添加UIView以定义您希望内部笔尖显示的空间。 / li>
- 从库中添加一个UIViewController对象，将其Nib Name属性设置为内部nib文件的名称（不带扩展名）。
- 创建IBOutlets对于外部视图控制器中的这两个项目并将它们连接起来。 （我将它们称为 innerView 和 innerViewController 。）
- 不要连接内部视图中定义的任何IBOutlet控制器到外部nib文件中的任何内容，只需将它们保持未连接状态。
- Add a UIView to define the space where you want your inner nib to display.
- Add a UIViewController object from the library, set its Nib Name property to the name of your inner nib file (without the extension).
- Create IBOutlets for these two items in your outer view controller and wire them up. (I'll refer to them as innerView and innerViewController.)
- Do not connect any of the IBOutlets defined in your inner view controller to anything in your outer nib file, just leave them unconnected.
在Xcode中
在外部视图控制器的 viewDidLoad 方法中，添加以下两行：
In Xcode
In your outer view controller's viewDidLoad method, add these two lines:
[self.innerView addSubview:self.innerViewController.view];
self.innerViewController.view.frame = CGRectMake(0, 0, self.innerView.frame.size.width, self.innerView.frame.size.height);
如果您的外部笔尖是自定义UITableViewCell，请将这些行放在 awakeFromNib 方法而不是。
If your outer nib is a custom UITableViewCell, put those lines in your awakeFromNib method instead.
Build&跑！
Build & Run!
