从嵌入在UIContainerView中的视图调用父视图的方法。斯威夫特

protocol ParentViewDelegate: AnyObject {
    func parentViewMethod()
}

class EmbeddedView: UIView {
    weak var delegate: ParentViewDelegate?
    
    // 嵌入视图的其他代码
}

class EmbeddedView: UIView {
    // 嵌入视图的其他代码
    
    func callParentViewMethod() {
        delegate?.parentViewMethod()
    }
}

class ParentViewController: UIViewController, ParentViewDelegate {
    // 父视图的其他代码
    
    func parentViewMethod() {
        // 实现父视图的方法逻辑
    }
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if let embeddedView = segue.destination as? EmbeddedView {
            embeddedView.delegate = self
        }
    }
}
