UIAAlert defaultButton and cancelButton return 'nil' on iOS 8

[jmoody]

I found bug in the UIAAlert API.

This is an Apple bug.

Workaround

If your UIAlert has two buttons, you can do this:

# Default button is index 1
> uia("uia.alert().buttons()[1].name()")
# Cancel button is index 0
> uia("uia.alert().buttons()[0].name()")

Reproduce

$ cd briar-ios-example/Briar
$ make app-cal
$ export APP=${PWD}/Briar-cal.app
$ be calabash-ios console
> start_test_server_in_background
> export APP=${PWD}/Briar-cal.app
> touch("button marked:'show alert'")
# Alert appears
> uia("uia.alert().defaultButton()")
> uia("uia.alert().cancelButton()")

Expected

{
    "status" => "success",
     "value" => "[object UIAButton]",
     "index" => 0
}

Actual

{
    "status" => "success",
     "value" => ":nil",
     "index" => 1
}

Regression

Repeat with iOS 7.1

irb(main):003:0> uia("uia.alert().defaultButton()")
{
    "status" => "success",
     "value" => "[object UIAButton]",
     "index" => 0
}
irb(main):004:0> uia("uia.alert().cancelButton()")
{
    "status" => "success",
     "value" => "[object UIAButton]",
     "index" => 1
}

Once the radar is filed, these can be closed.

Closing. Will report again if this appears in Xcode 7.

Cannot reproduce in Xcode 7 UIAutomation.

CalSmokeApp

UIATarget.onAlert = function onAlert(alert) {
    var title = alert.name();
    UIALogger.logWarning("Alert with title '" + title + "' encountered.");
    // return false to use the default handler
    return false;
}
var target = UIATarget.localTarget();

target.setDeviceOrientation(UIA_DEVICE_ORIENTATION_PORTRAIT);
target.frontMostApp().tabBar().buttons()["Special"].tap();
target.frontMostApp().mainWindow().elements()["special page"].buttons()["show alert"].tap();
UIALogger.logPass("alert: ".concat(target.frontMostApp().alert()))

// Alert detected. Expressions for handling alerts should be moved into the UIATarget.onAlert function definition.
UIALogger.logPass("button: ".concat(target.frontMostApp().alert().defaultButton().name()))

cancelButton() also works.
