寻找一种使用NSArray作为一堆按钮的插座的方法 [英] Looking for a way to use an NSArray as an outlet for a bunch of buttons

问题描述

我的用户界面有四个按钮，他们都将共享一些常见的行为，如跟踪区域创建一样的东西。我要找的是一个解决方案，所以我不必这样做：

My user interface has four buttons and they all will share some common behaviour, like tracking area creation a things like that. What I'm looking for is a solution so I don't have to do this:

@interface MyController : NSWindowController {
    NSButton * button1;
    NSButton * button2;
    NSButton * button3;
    NSButton * button4;
}
@property (nonatomic) IBOutlet NSButton * button1;
@property (nonatomic) IBOutlet NSButton * button2;
// and so on
@end

解决方案像这样：

@interface MyController : NSWindowController {
    NSMutableArray * buttons;
}
@property (nonatomic) IBOutlet NSMutableArray * buttons; 
// tell interface builder to place all buttons here
@end

这可能吗？

推荐答案

iOS 4.0添加了 IBOutletCollection 在Interface Builder中连接到多个对象。但是，Mac OS X不支持插座集合。

iOS 4.0 added IBOutletCollection, which allows an outlet to be connected to multiple objects in Interface Builder. However, Mac OS X does not support outlet collections.
