将项目连接到Interface Builder中的（特定索引）数组 [英] Connect items to a (specific index in) an array from Interface Builder

问题描述

这个应该是Objective-C专业人员的垒球：

This one ought to be a softball for the Objective-C pros out there:

有没有办法将界面构建器对象连接到NSArray的元素在Objective-C？连接通常用 IBOutlet 完成，如：

Is there a way to connect an interface builder object to an element of an NSArray in Objective-C? The connecting would normally be done with IBOutlet, as in:

@interface ViewController : UIViewController {
    IBOutlet UILabel *label1;
    IBOutlet UILabel *label2;
    IBOutlet UILabel *label3;
    //...
}

我可以将标签放入NSArray并仍将它们附加到界面构建器中的对象？

Can I put the labels in an NSArray and still attach them to objects in interface builder?

推荐答案

您应该能够使用IBOutletCollection，它本质上是一个数组IBOutlets。
使用此属性声明：

You should be able to use IBOutletCollection, which is essentially an array of IBOutlets. Use this property declaration:

@property (nonatomic, retain) IBOutletCollection(/*whatever object you want an array of e.g. UILabel*/) NSArray *seats;

您可以在界面构建器中将一种类型的多个对象连接到此。

You will be able to connect multiple objects of one type to this in Interface builder.
