问题描述
我创建了一个NSView的子类来绘制一个图像作为模式:
I have created a subclass of NSView to draw an image as a pattern:
@interface CePatternView : NSView
{
NSImage* image;
id observableObjectForImage;
NSString* keyPathForImage;
}
@end
我实现了以下操作bindings:
I implemented the following to expose bindings:
+ (void)initialize
{
// Expose the "image" binding to IB.
[self exposeBinding:@"image"];
}
- (Class)valueClassForBinding:(NSString *)binding
{
if([binding isEqualToString:@"image"])
return [NSImage class];
return nil; // Unknown binding
}
不幸的是,图片
我真的需要创建一个IBPlugin来暴露Interface Builder中的绑定吗?对于我不打算重用的自定义视图。
Do I really have to create an IBPlugin to expose bindings in Interface Builder? That just seems way overkill for a custom view that I don't plan to reuse.
推荐答案
标题答案不是,您可以绑定自定义视图没有IB插件(通过在代码中执行)。
对问题正文中的问题的回答:是的,您需要一个IB插件来暴露IB中的绑定。
Answer to title: No, you can bind a custom view without an IB plug-in (by doing it in code).
Answer to question in question body: Yes, you do need an IB plug-in to expose the binding in IB.
您的代码不会在Interface Builder中运行,除非将其放入Interface Builder中,并且 exposeBinding:
消息是您的代码。因此,你需要把它放到Interface Builder中。这意味着要编写一个IB插件。
Your code doesn't run inside Interface Builder unless you put it into Interface Builder, and that exposeBinding:
message is your code. Therefore, you need to put it into Interface Builder. That means writing an IB plug-in.
此外,IB插件与旧的IB调色板不同。插件需要IB 3,并且更容易创建。调色板需要IB 2,创建起来很痛苦。
Also, IB plug-ins are not the same as the old IB palettes. Plug-ins require IB 3 and are much easier to create. Palettes require IB 2 and were painful to create.
