I get a warning,it says "requestDidFinish" method conflicts (AppleRequest.o) with the same method in another category. Anyone can tell me how I can find this method.I am pretty sure I do not use the method, probably in some other third library .And I wonder what is the AppleRequest.o.Thanks a lot.
some method conflicts
A google search suggests the conflicting method is from the StoreKit framework.

Generally, you could find the conflicting method/selector by commenting out your version, writing a call to that selector on an instance typed as id (and arguments of type id), and then using command-double-click to pull up the header in another window.
id thing = nil;
[thing selectorToFind:thing];
