appium基础：滑屏和画九宫格踩坑'NoneType' object has no attribute 'execute'

最近接触到app操作：滑动屏幕和设置九宫格手势密码，发现挺好玩的，写篇博客记录一下遇到的问题，附代码

滑屏swip

  通常打开一个app有引导页，一般是向左滑动几次后才能到主页，appium借助swip方法实现

  使用方法  driver.swipe(x1,y1,x2,y2)

  其中 x、y是指坐标，由一个坐标位置(x1,y1)滑到另一个坐标位置(x2,y2)

  由于手机屏幕尺寸有大有小，所以我们确定x/y时一般要获取手机屏幕大小，使用相对位置滑动

  例：

driver.swipe(screen['width'] * 0.9, screen['height'] * 0.6, screen['width'] * 0.2, screen['height'] * 0.4)

九宫格

 相信大家有见过九宫格，手工设置九宫格的方法是按住第一个点不放，依次移动到相应的点后松手

 借助TouchAction类实现，看类名应该是很好理解的，就是触屏操作

 首先进行实例化：

tc = TouchAction(driver)

 实现步骤：

tc.press(x=x1, y=y1).wait(200).move_to(x=x2, y=y2).wait(200).move_to(x=x3, y=y3]).wait(200). 
    move_to(x=x4, y=y4).wait(200).move_to(x=x5, y=y5).wait(200).release().perform()

#截图
driver.save_screenshot('C:\Users\adminDesktop\screen.png')
driver.find_element_by_id('com.xxzb.xxx:id/right_btn').click()
time.sleep(2)

注意：这里本人踩了一个坑：运行的时候报错：'NoneType' object has no attribute 'execute'

浪费了很多时间，最后发现是实例化时没有传递driver，改成tc = TouchAction(driver)就好了
