swift - 如何从 XIB 文件加载自定义创建的 View 并添加到 StackView

Question

我有 XIB 文件，其中有 UIView 类型的类，并且我不会在根 ViewController 中加载该 XIB:

导入UIKit

ViewController 类:UIViewController {

// MARK: - Variables


// MARK: - IBOutlets

@IBOutlet private weak var mainStackView: UIStackView!


// MARK: - LifeCycle Methods

override func viewDidLoad() {
    super.viewDidLoad()


    if let view = CustomView.instanceFromNib() {

    let view = CustomView.instanceFromNib() as! CustomView
        mainStackView.addArrangedSubview(view)
        mainStackView.addArrangedSubview(view)
        mainStackView.addArrangedSubview(view)
    }   
}

}

导入基础导入 UIKit

类 CustomView:UIView {

static let id = "CustomView"


@IBOutlet weak var backgroundImageView: UIImageView!

override func awakeFromNib() {
    super.awakeFromNib()
}

static func instanceFromNib() -> UIView {
    return UINib(nibName: "UserReview", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! UIView
}

override init(frame: CGRect) {
    super.init(frame: frame)

}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}

}

此类不符合键值backgroundImageView的键值编码。'

您是 Xib 文件的文件所有者吗？将 CustomView 类分配给 Xib 文件的所有者
