Appium 版本是 1.6.3
设备是 iphone6 IOS9.3.4
之前用 1.5.3 版本的 Appium 已经可以在真机上跑通自己项目的自动化脚本了，想换 1.6.3 版本试一下 WebDriverAgent
已经照着https://testerhome.com/topics/4904 安装好 WebDriverAgent 了
脚本中初始化的代码如下：

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("automationName", "XCUITest");
capabilities.setCapability("appium-version", "1.0");
capabilities.setCapability("platformName", "iOS");
capabilities.setCapability("platformVersion", "9.3.4");
capabilities.setCapability("deviceName", "iPhone");
capabilities.setCapability("udid", "d69d11788a251a64fc31dfbc93c9053cfca5cbca");
capabilities.setCapability("app", "/Users/yefengjun/Downloads/Products Bundle ID：com.JDVideo/Debug-iphoneos/JDLive.app");
wd = new AppiumDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities) 

说下步骤：
在终端中启动 WebDriverAgent

cd  /usr/local/lib/node_modules/appium/node_modules/appium-xcuitest-driver/WebDriverAgent
xcodebuild -project WebDriverAgent.xcodeproj -scheme WebDriverAgentRunner -destination 'id=d69d11788a251a64fc31dfbc93c9053cfca5cbca' test

之后启动 Appium 服务
运行日志如下
