ios NSXMLDocument 为什么报错 ，需要导入什么框架 包 啊

Answer 1

NSXMLElement is only supported on OSX.
You can use GDataXMLElement, all interfaces and signatures are exactly the same.
Don’t forget after joining:

Add this line to 'Header Search Paths' (use search bar to find the right option) /usr/include/libxml2
Add this line to 'Other Linker Flags': -lxml2
