Swift iOS -如何将结果打印到特定标签/图像/等

let resultLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 30))
resultLabel.text = "结果"

let resultImage = UIImage(named: "result.png")
let resultImageView = UIImageView(image: resultImage)

let resultTextView = UITextView(frame: CGRect(x: 0, y: 0, width: 200, height: 100))
resultTextView.text = "结果"

class ResultView: UIView {
    var result: String = "" {
        didSet {
            // 更新显示结果的逻辑
        }
    }
}
