Appium [求助] iOS 真机开启 appium 服务后，inspector 无法调起
说明：iphone6 plus 8.1.2 appium GUI 1.3.3
xcode 模拟器运行工程，可正常启动，使用可真机调试的开发者证书打包应用到真机，工程也正常运行。
appium gui 设置中，勾选并填写正确的 bundle id udid， force device 为 iphone6 plus，server address 为 127.0.0.1，其他均未勾选。
步骤：使用 xcode 将应用打包到真机中，退出 Xcode，启动 appium GUI,启动 appium 服务，点击 inspector，手机上应用被拉起，然后一会儿退回手机桌面，应用被再次拉起，重试多次后报错无法拉起 inspector。必现。日志中的错误 Could not start script, target application is not frontmost.查了资料也没找到对应的解决办法，请各位大神指教。
以下是运行时日志：

我也遇到过这种情况，你看看你 Xcode 里面模拟器安装的对嘛？需要下载对应版本模拟器的
他是真机。不过真机是可以运行的。只是你不会。
发帖还是要遵循规矩的。
#3 楼 @lihuazhang 首先承认错误，后续发帖务必先看清要求。然后是问题，使用开发者证书打的包可以在真机运行，appium GUI 也能拉起应用（只是提示 ail: Could not start script, target application is not frontmost.），是不是能证明本身打包和证书是没问题的，也看了你的真机运行的文章，目前还不能确定问题可能出在哪边，还望能指正，是证书问题？appium 配置问题？版本匹配问题？多谢！
以上是配置截图
#4 楼 @313077271 真机端有配置么？
手机设置里面有个开发者，里面把 Enable UI Automation 打开试试
#6 楼 @lihuazhang 真机端将 Enable UI Automation 打开了，还需要其他什么设置？
#7 楼 @mouseyoung 打开了。我怀疑是打包的问题，请问打包需要什么特别的要求吗？使用的是开发者证书打的包，本机的 UDID 也加到了 provision 文件中。
#9 楼 @313077271 开发证书是可以的。

连接真机，打开被测工程，点击 Product—>Profile,完全退出自动启动的 instruments，在 xcode 文件夹中找出刚刚生成的.app 文件，拷出来后 appium 里设置 AppPath，和其他必要参数，Launch,打开 inspector，我平常是这么个流程，你试试看可以嘛？
我运行时候也是介个样子，然后重启或者手机等一下就好了。。。
