如何以编程方式复制界面构建器中内置的UIViews？ [英] How do I programmatically duplicate UIViews built in interface builder?

问题描述

我想在Interface Builder中构建一个子UIView（包含在UIScrollView中），其中包含一些UILabel，然后我想以编程方式复制此视图调整其左侧位置（通过其宽度的倍数）来实现在UIScrollView中浮动左侧效果。然后，我想将这个复制的UIView添加回UILcrollView，并为UILabels添加不同的文本。

I want to build up a sub-UIView in Interface Builder (contained within a UIScrollView) with some UILabels contained, I then want to programmatically "copy" this view adjust its left position (by multiples of its width) to achieve a "floating" left effect inside a UIScrollView. I then want to add this copied UIView back into the UIScrollView with different text for the UILabels.

问题是我不知道如何以及如果你可以复制 UIViews。

The problem is I don't know how and if you can "copy" UIViews.

推荐答案

您可以尝试调用[查看副本]，但如果不起作用我也不会感到惊讶。您可以使用NSKeyedArchiver / NSKeyedUnarchiver来序列化/反序列化视图，但这也非常糟糕。

You can try calling [view copy], but I wouldn't be surprised if that didn't work. You can probably use NSKeyedArchiver/NSKeyedUnarchiver to serialize/deserialize the view, but that's also pretty terrible.

相反，您可能希望加载视图的多个副本：

Instead, you probably want to load multiple copies of the view:

1. 将您想要多份副本的视图移动到自己的笔尖中。


2. 使笔尖拥有通过你的对象（你想要负责加载它的任何类）。


3. 添加名为myView的IBOutlet或其他任何东西，并将其分配给你的视图。


4. 在课堂上，请拨打以下内容：

1. Move the view you want multiple copies of into its own nib.
2. Make the nib "owned" by your object (whatever class you want to be responsible for loading it).
3. Add an IBOutlet called "myView" or whatever, and assign it to your view.
4. In your class, call something like:

-(UIView)makeMeANewMyView {
  // Load MyView.nib into the myView outlet.
  [[NSBundle mainBundle] loadNibNamed:@"MyView" owner:self];
  // Take ownership.
  UIView * view = [[self.myView retain] autorelease];
  self.myView = nil;
  return view;
}
