如何使 UIControl 在 XCUITest 中显示为按钮？

Question

我创建了一个 UIControl 的子类，它的行为应该类似于 UIButton。

当我运行我的 UI 测试使用 XCUI测试按钮出现在 XCUIApplication().staticTexts 而不是预期的 XCUIApplication().buttons.

Answer 1

四处寻找后，我发现这是由于未设置可访问性特征所致。例如，如果我有以下 class;

class ActivityButton: UIControl {

    private let activityIndicator: UIActivityIndicatorView = {
        let activityIndicator = UIActivityIndicatorView()
        activityIndicator.hidesWhenStopped = true
        activityIndicator.translatesAutoresizingMaskIntoConstraints = false
        return activityIndicator
    }()

    let titleLabel: UILabel = {
        let titleLabel = UILabel()
        titleLabel.translatesAutoresizingMaskIntoConstraints = false
        return titleLabel
    }()

    override public init(frame: CGRect) {
        super.init(frame: frame)
        // This is the required call to make the control appear 
        // as a button in ui tests
        accessibilityTraits = UIAccessibilityTraitButton
        addSubview(activityIndicator)
        addSubview(titleLabel)
        createConstraints()
    }    

}
