python+Appium自动化：MultiAction多点触控
MultiAction
MultiAction 是多点触控的类，常用于模拟用户多点操作。
主要包含这add（）还有perform（）两个方法，模拟多点触控，需要导入TouchAction还有MultiAction两个模块。
from appium.webdriver.common.multi_action import MultiAction
from appium.webdriver.common.touch_action import TouchAction
加载：
方法add(self, *touch_actions)将TouchAction对象添加到MultiAction中
touch_actions 是一个或多个TouchAction对象，描述一个手指要执行的动作链
例子：action1=TouchAction(driver)
action1.press(el1).move_to(el2).release()
action2=TouchAction(driver)
action2.press(el2).move_to(el1).release()
MultiAction(driver).add(action1, action2)
执行：
perform(self) 执行存储在对象中的操作
action1=TouchAction(driver)
action1.press(el1).move_to(el2).release()
action2=TouchAction(driver)
action2.press(el2).move_to(el1).release()
MultiAction(driver).add(action1, action2).perform()
场景：百度地图的缩放

zoom()move_to是计算手机的偏移量，用负数控制滑动方向。
