如何找到连接到特定IBOutlet的UI元素？ [英] How to find the UI element connected to a specific IBOutlet?

问题描述

有没有办法找到在代码中声明的IBOutlet连接到哪个UI元素？

Is there any way to find which UI element an IBOutlet declared in code is connected to?

推荐答案

转到您已声明 IBOutlet 的视图控制器文件（ .h或.m）。然后你可以看到每个变量声明的左侧有一个深灰色的圆形图像。 （如果您已将IBOutlet与Storyboard / Xib相连，除非它未填充，否则会填充。）

Go to your view controller file where you have declared IBOutlet (.h or .m). Then you can see left side of each variable declaration there is a dark grey round image. (It is filled if you have connected that IBOutlet with Storyboard/Xib unless it is unfilled.)

通过单击该图像，您可以看到显示插座连接的小弹出窗口。见下图将显示给你。

By clicking that image you can see small popover which shows connection of outlet. See below image will show you.
