iOS 开发让应用文件夹显示在文件中

在InfoPlist添加以下键，并且全部设置为YES(括号里的是平时显示的键)
CFBundleAllowMixedLocalizations (Localized resources can be mixed)
UIFileSharingEnabled (Application supports iTunes file sharing)
UIApplicationSupportsIndirectInputEvents. (Application supports indirect input events)
LSSupportsOpeningDocumentsInPlace
LSRequiresIPhoneOS

如需隐藏应用文件夹只需将 UIFileSharingEnabled 的值设为NO
