在你的头文件中创建一个 IBoutlet 并合成它。按住 conrtol 并将其拖到您的头文件中。选择 iboutlet 给它一个名字。你已准备好出发。然后使用你的插座

Add two button in the main storyboard view object. Set button text, and background color to green. You can read iOS Add Click Event To UIButton Swift Example to learn how to add button click event function.
在主故事板视图对象中添加两个按钮。将按钮文本和背景颜色设置为绿色。你可以阅读 iOS Add Click Event To UIButton Swift Example 来学习如何添加按钮点击事件功能。
import UIKit
class ViewController: UIViewController {
// Create the subview object.
private let childView = UIView();
// When click the second button will invoke this method.
@IBAction func removeSubView(_ sender: UIButton, forEvent event: UIEvent) {
// Remove the child view.
childView.removeFromSuperview();
}
// Invoked when click the first button.
@IBAction func addSubView(_ sender: UIButton, forEvent event: UIEvent) {
// Add the child view.
self.view.addSubview(childView);
}
override func viewDidLoad() {
super.viewDidLoad()
// Set child view x y cordinate and size.
childView.frame = CGRect(x: 80, y: 100, width: 200, height: 100)
// Set child view background color.
childView.backgroundColor = UIColor.green
}
}
