如何从一个对象数组中制作IBOutlets？ [英] How to make IBOutlets out of an array of objects?

问题描述

我想用Interface Builder中的一堆UIImageViews创建一个数组。而不是20或30

I want to make an array with a bunch of UIImageViews I have in Interface Builder. Instead of having 20 or 30

IBOutlet UIImageView *img1;

并将它们全部链接起来，然后将它们放入数组中，是否有办法声明一组IBOutlet UIImageViews？

and linking them all that way, and then putting them into an array, is there a way to declare an array of IBOutlet UIImageViews?

我的头文件中没有这么多声明。

Just so I don't have so many declarations in my header file.

推荐答案

有可能，它被称为 outlet collection 。这是定义outlet集合的方法：

It is possible, it’s called outlet collection. This is the way to define an outlet collection:

@property(retain) IBOutletCollection(UIImageView) NSArray *images;

现在您可以在Interface Builder中将多个对象粘贴到插座中，将创建该阵列在你加载界面时为你服务。

Now you can stick more than one object into the outlet in the Interface Builder, the array will be created for you when the interface is loaded.
