问有没有办法在UI测试中自动化SFSafariViewController？

EN

func tapElementInActionSheetByPosition(element: XCUIElement!) {
    let tableSize = app.tables.elementBoundByIndex(0).frame.size
    let elementFrame = element.frame

    // get the frame of the cancel button, because it has a real origin point
    let CancelY = app.buttons["Cancel"].frame.origin.y

    // 8 is the standard apple margin between views
    let yCoordinate = CancelY - 8.0 - tableSize.height + elementFrame.midY

    // tap the button at its screen position since tapping a button in the extension picker directly is currently broken
    app.coordinateWithNormalizedOffset(CGVectorMake(elementFrame.midX / tableSize.width, yCoordinate / app.frame.size.height)).tap()
}

private func coordinate(forWebViewElement element: XCUIElement) -> XCUICoordinate? {
    // parse description to find its frame
    let descr = element.firstMatch.debugDescription
    guard let rangeOpen = descr.range(of: "{{", options: [.backwards]),
        let rangeClose = descr.range(of: "}}", options: [.backwards]) else {
            return nil
    }

    let frameStr = String(descr[rangeOpen.lowerBound..<rangeClose.upperBound])
    let rect = CGRectFromString(frameStr)

    // get the center of rect
    let center = CGVector(dx: rect.midX, dy: rect.midY)
    let coordinate = XCUIApplication().coordinate(withNormalizedOffset: .zero).withOffset(center)
    return coordinate
}

func tap(onWebViewElement element: XCUIElement) {
    // xcode has bug, so we cannot directly access webViews XCUIElements
    // as workaround we can check debugDesciption, find frame and tap by coordinate
    let coord = coordinate(forWebViewElement: element)
    coord?.tap()
