What framework can i use to create gmail-client iphone application?

I've tried MailCore - have a problem with "library not linked" "reason - image not found"/ adding new copy file build phaze doesn't solve it; tried to use pantomime but have over 1000 errors with #include <Pantomime/Somefile.h> (i changed all this #include <Pantomime/Somefile.h>开发者_开发技巧; for #import "Somefile.h") its becouse a i used not a framework but an open-source library; and i tried to add EDMessage framework - but i think it's for cocoa but not for cocoa touch becouse i had an error with NSCalendarDate. i can't use MessageUI becouse i need a full client to receive and send messages.

Pantomime is too big and not well documented. You can try:

• MailCore (it works, check how are you including it)
• libetpan, plain c, low level, it's the underlying library in MailCore (last time I checked)
• letters, Cocoa, IIRC requires blocks
