如何将AppiumDriver焦点更改为出现在不同图层上的下拉列表？iOS

from appium import webdriver
from appium.webdriver.common.mobileby import MobileBy
from appium.webdriver.common.touch_action import TouchAction

# 设置Appium的Desired Capabilities
desired_caps = {
    "platformName": "iOS",
    "deviceName": "iPhone 12",
    "app": "/path/to/your.app",
    "automationName": "XCUITest"
}

# 初始化AppiumDriver
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

# 假设下拉列表的Accessibility ID是'dropdownList'
dropdown = driver.find_element(MobileBy.ACCESSIBILITY_ID, 'dropdownList')

# 点击下拉列表以展开选项
dropdown.click()

# 假设你想选择的下拉列表项的Accessibility ID是'option1'
option = driver.find_element(MobileBy.ACCESSIBILITY_ID, 'option1')

# 点击选项以选择它
option.click()

# 如果下拉列表是通过滚动来访问的，可以使用TouchAction
actions = TouchAction(driver)
actions.press(element=dropdown).move_to(x=0, y=50).release().perform()

# 再次查找并点击选项
option = driver.find_element(MobileBy.ACCESSIBILITY_ID, 'option1')
option.click()

# 关闭driver
driver.quit()
