在使用plist和tableviw在detailview的webview中加载html文件时遇到问题
  • 我有a1.html，a2.html，b1.html，b2.html作为应用程序内的本地资源。
  • 我无法使用plist和tableview将这些html文件加载到detailview的webview中

PLIST

topics.plist 

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>HN</key> <array> <dict> <key>Name</key> <string>Boston</string> <key>File</key> <string>a1</string> </dict> <dict> <key>Name</key> <string>Massachussets</string> <key>File</key> <string>a2</string> </dict> </array> <key>LEA</key> <array> <dict> <key>Name</key> <string>Birmingham</string> <key>File</key> <string>b1</string> </dict> <dict> <key>Name</key> <string>Alabama</string> <key>File</key> <string>b2</string> </dict> </array>
