Cordova app hanging during startup on iOS 10

阅读更多关于 Cordova app hanging during startup on iOS 10

I just installed Xcode 8 beta in order to test my existing Cordova app in iOS 10 beta (via Simulator). When the app is launched, it just hangs on the loading page - seems the deviceready event is not being fired. So I also installed iOS 10 beta on my iPad Air (just in case it's a Simulator issue), but I get the same results. The app works fine on iOS 9.3 (both device and Simulator). Anyone encountered/fixed this problem? UPDATE Other symptoms of this problem include: the app will start correctly if you background the app (switch back to the home screen) then foreground the app (switch back to
