为什么当我将 UIButton 或 UILabel 拖放到 ViewController.swift 文件时类型总是 UIView

Question

Below is the screenshot. This is the problem I face when I drag and drop either a UILabel or UIButton .

Please help me I am a beginner and I have just started. I just added a button and a label and want to change text in label upon button click but I am facing this problem.

Answer 1

When dragging from the storyboard to the class file to create an IBOutlet , if the containing view is selected in the navigator (as shown in your screenshot), then that will be linked to the outlet.

To make sure you're connecting to the correct object either

• Select it first by clicking on it, either in the navigator or on the storyboard itself

or

• Drag directly from the navigator

似乎您正在尝试为Label Message View 而不是Label创建一个插座，为什么它总是UIView
