Using GDataXMLDocument in iPad app
- by INs
I'm trying to use GDataXML library in my ipad application. I followed by instructions:
Download the gdata-objective-c client library.
Unzip the file, navigate to Source\XMLSupport, and drag the two files GDataXMLNode.h and GDataXMLNode.m into your project
In XCode, click Project\Edit Project Settings and make sure “All Configurations” are checked.
Find the Search Paths\Header Search Paths setting and add /usr/include/libxml2 to the list.
Finally, find the Linking\Other Linker Flags section and add -lxml2 to the list.
If in code i add #import "GDataXMLNode.h", all is fine. But when i try to use GDataXMLDocument class in my app
GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:xmlData options:0 error:nil];
I received the following message:

Any thoughts?
