关于appium中的Multiaction的用法

比如pinch:两个手指向内滑动          zoom：两个手指向外滑动

首先

from appium.webdriver.common.touch_action import TouchAction

from appium.webdriver.common.multi_action import MultiAction

def pinch():
    action1=TouchAction(driver)
    action2=TouchAction(driver)
    pinch_action=MultiAction(driver)

    action1.press(x=x*0.2,y=y*0.2).wait(1000).move_to(x=x*0.4,y=y*0.4).wait(1000).release()
    action2.press(x=x*0.8,y=y*0.8).wait(1000).move_to(x=x*0.6,y=y*0.6).wait(1000).release()

    pinch_action.add(action1,action2)
    print('start pinch...')
    pinch_action.perform()

def zoom():
    action1 = TouchAction(driver)
    action2 = TouchAction(driver)
    zoom_action = MultiAction(driver)

    action1.press(x=x * 0.4, y=y * 0.4).wait(1000).move_to(x=x * 0.2, y=y * 0.2).wait(1000).release()
    action2.press(x=x * 0.6, y=y * 0.6).wait(1000).move_to(x=x * 0.8, y=y * 0.8).wait(1000).release()

    zoom_action.add(action1,action2)
    print("start zoom...")
    zoom_action.perform()
