MobileFirst 如果我扩展 WLAppDelegate，我迁移的 iOS 项目无响应，但如果我扩展 WLCordovaAppDelegate 则没有

Question

我已使用 MobileFirst Studio 将 9 个 iOS 混合应用程序从 MobileFirst 6.3 迁移到 MobileFirst 7.1。其中 4 个应用程序运行良好。但是另外 5 个，UI 对点击没有响应。作为自动迁移过程的一部分，这 5 个应用程序的标头（仅）已更改为引用新的 WLAppDelegate 接口。奇怪的是，我注意到如果我将 AppName.h 文件从扩展 WLAppDelegate 切换回扩展原始 WLCordovaAppDelegate，一切正常。为什么？我很乐意将此已弃用的代码移至您的新 WLAppDelegate 界面。

当您请求新的 iOS 应用程序时，我的标头和 .m 文件与 MobileFirst Studio 7.1 生成的默认值相匹配，因此它必须是其他内容。

这是我的非工作 .h 和 .m 文件

#import <IBMMobileFirstPlatformFoundationHybrid/IBMMobileFirstPlatformFoundationHybrid.h>


@interface MyAppDelegate : WLAppDelegate <WLInitWebFrameworkDelegate> {

}

WLCordovaAppDelegate 是一个已弃用的兼容性 API，可让您更轻松地将 v6.2 之前的应用迁移到 6.2+ 应用。可以使用，但建议使用WLAppDelegate。
