plist文件的内容格式和xml文件的内容格式是一样的，测试的data.plist文件内容如下：

<?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>name</key>
	<string>Hello World</string>
	<key>age</key>
	<integer>28</integer>
</dict>
</plist>
