我有一个简单的函数，它应该检查视图是否在主界面，如果不是，将其带到主界面：

function returnHome() {
    if (UIATarget.localTarget().frontMostApp().navigationBar().name() == mainTitle) return true;

    // set tab bar to calculations
    UIALogger.logMessage("Set tab bar to main.");
    if (UIATarget.localTarget().frontMostApp().tabBar().selectedButton().name() != mainTabName) {
        UIATarget.localTarget().frontMostApp().tabBar().buttons()[mainTabName].tap();
    }

    // go back to the home
    UIALogger.logMessage("Go back to home.");
    var backButton = UIATarget.localTarget().frontMostApp().mainWindow().buttons()["Back"];
    if (backButton.isValid()) {
        backButton.tap();
    } else {
        UIALogger.logError("Could not find 'Back' button!");
    }
}

现在，我无法通过错误“找不到'返回'按钮！”。它就在上面，在左角，正盯着我，嘲弄我！

这UIATarget.localTarget().frontMostApp().logElementTree()给了我以下树：

5) UIAButton [name:tab3 value:(null) rect:{{x:215, y:432}, {width:103, height:48}}]

日志清楚地显示了“返回”按钮，但我没有得到适当的参考。谁能在这里指出我正确的方向？难道我做错了什么？仅供参考，我尝试从frontMostApp()、mainWindow() 和navigationBar() 访问buttons()。都失败了。

“返回”按钮不是窗口的直接子窗口，而是导航栏。尝试使用以下代码访问它：

   var backButton = UIATarget.localTarget().frontMostApp().mainWindow().navigationBar().buttons()["Back"];

你是如何构建视图层次结构的？从日志中，您可以在一个 UIWindow 下看到两个导航栏：一个未标记，一个标有mainNavigationBar.

正如克劳斯指出的那样，您应该能够通过访问主窗口的导航栏来获得后退按钮，但由于存在第二个导航栏，这可能会在您的情况下失败。

如果有帮助，以下是我编写的脚本，它逐步遍历 UICatalog 示例应用程序中的每个部分，抓取该部分的屏幕截图，然后返回到导航控制器的主级别。在此示例中，我使用leftButton()访问导航栏上的后退按钮。

var target = UIATarget.localTarget();
var application = target.frontMostApp(); 
var mainWindow = application.mainWindow();
var tableView = mainWindow.tableViews()[0];


UIALogger.logMessage("Number of cells " + tableView.cells().length);

for (var currentCellIndex = 0; currentCellIndex < tableView.cells().length; currentCellIndex++)
{
    var currentCell = tableView.cells()[currentCellIndex];
    UIALogger.logStart("Testing table option " + currentCell.name());

    currentCell.scrollToVisible();  

    target.delay(1);
    currentCell.tap();  // Go down a level
    target.delay(1);

    UIATarget.localTarget().captureScreenWithName(currentCell.name());
    mainWindow.navigationBar().leftButton().tap(); // Go back
    target.delay(1);
    UIALogger.logPass("Testing table option " + currentCell.name());
}

也许它不是一个真正的按钮。我遇到了类似的问题，日志将它作为按钮返回，但它实际上是一个视图。因此，我的解决方案是找到项目（可以是图像），然后获取 rect(x, y)，然后在屏幕上使用特定位置的选项卡，例如 target.tapWithOptions({x:5, y:190}); 希望这会有所帮助，干杯
