如果我扩展WLAppDelegate，我的迁移iOS项目无法响应，但如果扩展WLCordovaAppDelegate则不会

I've migrated 9 iOS Hybrid apps from MobileFirst 6.3 to MobileFirst 7.1 using MobileFirst Studio. 4 of the apps work fine. But the other 5, the UI is unresponsive to clicks. As part of the automated migration process, the headers of these 5 apps (only) were changed to reference the new WLAppDelegate interface. Strangely I've noticed that if I switch my AppName.h file from extending WLAppDelegate back to extending the original WLCordovaAppDelegate everything works fine. Why? I'd love to move off this deprecated code to your new WLAppDelegate interface.I've migrated 9 iOS Hybrid apps from MobileFirs
