实际有效使用IBOutletColletion [英] Practical efficient usage of IBOutletColletion

问题描述

如何看待IBOutletCollection的实际用法？不幸的是，Apple文档在没有更广泛的使用概念的情况下提及了它。好吧，它与IB保持一对多的关系，但如何有效地访问和使用特定对象？使用TagName？如何确保对象的顺序？

How does look the practical usage of IBOutletCollection? Unfortunately Apple documentation mentions it briefly without giving an wider idea of usage. OK, it maintains one-to-many relation with IB, but how to access and use particular objects efficiently? With TagName? How to ensure the order of objects?

我最近使用它来轻松初始化标签网格。我在视图上有一个n×n标签矩阵，并分别引用每个标签（通过IBOutlet）以显示相关数据。但是，当视图首次加载时，我想控制所有标签中显示的默认文本。最初我想要一个破折号显示，但由于这是一个客户，我希望它很容易改变。根据客户端请求，视图内容会随着时间的推移而不断变化。

I've recently used this to easily initialize a grid of labels. I have a n by n matrix of labels on a view, and reference each one individually (via an IBOutlet) in order to display relevant data. However when the view first loads I wanted to control the default text that displayed in all the labels. Initially i wanted a dash to display, but since this is for a client I wanted it to be easy to change. The view contents have and continue to change over time, per client requests.

我创建了一个IBOutletCollection并在4中完成了相同的结果，而不是编写N行代码。 @property，@synthesize和for循环）。 YMMV，但我发现它在这种情况下非常有用。

Instead of writing N line of code, I created an IBOutletCollection and accomplished the same results in 4 (@property, @synthesize, and for loop). YMMV but I found it very useful in this situation.
