我刚开始使用UIAutomation使用https://github.com/KrauseFx/snapshot截取我的应用的屏幕截图。
我的问题：
该应用程序编译，模拟器似乎打开应用程序，但只是显示一个黑屏。这有什么不对吗？
如果我通过XCode运行应用程序，一切正常。
#import "SnapshotHelper.js"
var target = UIATarget.localTarget();
var app = target.frontMostApp();
var window = app.mainWindow();
target.delay(3)
target.frontMostApp().mainWindow().buttons()["Info"].tap();
captureLocalizedScreenshot("0-LandingScreen")
我收到了这个日志，但不知道如何阅读。
