Storyboard中使用的清除标签文本 [英] Clear Label text used in Storyboard

问题描述

想知道是否有人知道如何完成以下操作......

Wondering if anyone know hows to complete the following...

在故事板中我设置了我的标签使用虚拟文本，它们不是静态文本。例如'User1 Username'。

In a Storyboard I set my Labels with dummy text, they are not Static text. For example 'User1 Username'.

如果有一个设置在视图加载时清除此标签的值，我将会知道。我还有一些其他代码可以运行并收集相关信息。但是，可能需要几秒钟才能在用户加载时向用户显示HUD。

What I would to know if there is a setting to clear the value of this label when it is loaded by the view. I have some other code that runs off and collects the relevant information. However, it might take a few seconds so a HUD is shown to the user whilst it loads.

当然，在HUD的背景中，您可以看到显示的示例文本。我知道在 viewDidLoad 我可以简单地清除所有标签文本，将它们设置回 @，但是没有故事板中的设置或其他任何内容？

Of course in the background of the HUD you can see the example text shown. I know in viewDidLoad I could simply clear all the label texts setting them back to @"", but is there no setting in the storyboard or anything for this?

推荐答案

您可以使用用户定义的运行时属性来实现这个。只需为任何 UILabel ， UITextField 或 UITextView 设置text属性即可获得所需内容：

You can use User Defined Runtime Attributes to achieve this. Simply set "text" attribute for any UILabel, UITextField or UITextView to get what you want:

使用Storyboard时，KVC和运行时属性非常强大（例如，您是否知道可以将layer.cornerRadius属性设置为任何UIView以获取舍入的角落？）。

KVC and runtime attributes are really powerfull when working with Storyboard (e.g. did you know that you can set "layer.cornerRadius" attribute to any UIView to get rounded corners?).
