上一篇介紹完如何安裝WDA，接下來開始正式安裝開發庫並編寫自動化腳本。
目錄：
一、安裝facebook-wda庫
運行命令行安裝：
pip install --pre facebook-wda
或者使用pycharm中，Preferences->Project->Project Interpreter->【+】(加號), 搜索：facebook-wda，並安裝
舉個栗子，頁面元素定位，如下圖，class、name一一展示：
通過“ideviceinstaller -l ”或者其他工具查找到APP軟件的bundleId
$ ideviceinstaller -l Total: 5 apps com.ysr.scancode - 二維碼掃描器 3 com.apple.test.WebDriverAgentRunner-Runner - WebDriverAgentRunner-Runner 1 com.sogou.sogouinput - 搜狗輸入法 142709 com.netease.cloudmusic - 網易雲音樂 1044 com.leqimea.recorderAudio - PP助手 10000
但是，會一直報錯Could not connect to lockdownd. Exiting.
痛苦了大半天，終於找到了解決辦法：
參考：《IOS 執行ideviceinstaller -l ,結果報錯Could not connect to lockdownd. Exiting.》
上代碼：
#!/usr/bin/env python # -*- coding: utf-8 -*- # @Time : 2018/10/16 11:42 # @Author : zc # @File : test.py import unittest import wda wda.DEBUG = False # default False wda.HTTP_TIMEOUT = 10.0 # default 60.0 seconds bundle_id = "com.chen.CityMineSafetyOne" （通過上面獲得） c = wda.Client('http://localhost:8100') # 啟動應用 s = c.session(bundle_id) class Test_safety(unittest.TestCase): def setUp(self): print("=======start!=======") pass def tearDown(self): print("=======stop!=======") pass def test1(self): # class、name定位參考網易圖所示，這里只是舉個栗子，並不是網易代碼 s(name='home btn newtask',className='Button').tap() if __name__ == '__main__': unittest.main()
運行成功！！！！
二、通過WEditor定位元素 返回目錄
之前做uiautomator2-Android自動化時，用到了這個進行定位元素，非常方便，facebook-wda-IOS自動化也可以通過這個進行定位元素。
首先，啟動weditor
python -m weditor
有時候會報錯：OSError: [Errno 48] Address already in use
提示您地址已經被占用，所以我們可以查看weditor的17310端口，看看哪些軟件占用了此端口：
# 查看端口使用情況 lsof -i tcp:17310 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME Google 396 zhan 156u IPv6 0x9b9eee3e3dae5dfb 0t0 TCP localhost:58732->localhost:17310 (ESTABLISHED) python3.6 8244 zhan 4u IPv6 0x9b9eee3e34507f3b 0t0 TCP *:17310 (LISTEN) # 其中谷歌和py3.6占用了端口，選擇殺死進程 kill 396 kill 8244
接着再啟動weditor，發現還是報錯：
ModuleNotFoundError: No module named 'atx'
需要安裝atx：

You should consider upgrading via the 'pip install --upgrade pip' command.
在安裝cv2，作用是讀取圖像相關的：
pip install opencv-python
再次運行weditor，又發生錯誤：
from atx import ioskit
File "/Users/zhangc/.pyenv/versions/3.6.1/lib/python3.6/site-packages/atx/ioskit.py", line 199
print dev.screenshot('i.png')
^
SyntaxError: invalid syntax
語法錯誤，經過大神調試得知原來是，atx版本問題，升級atx版本。
# 查看pip下各個庫的版本 pip list # 得知 atx (1.1.2.dev18) pip (9.0.1) # 升級pip pip install --upgrade pip # 升級atx pip install -U atx # 再查看pip下各個庫版本 Package Version --------------- ----------- atx 1.2.0 pip 18.1 # 最后再運行weditor python -m weditor
weditor終於啟動成功！！！！！
瀏覽器自動打開weditor，選擇IOS，輸入地址：http://localhost:8100，點擊【Connect】連接，出現小綠葉🍀表示連接成功，再點擊藍色按鈕【Reload】刷新如下：
至此facebook-wda安裝以及元素定位講解到此為止。
