I found the answer
[[EvernoteNoteStore noteStore] listTagsWithSuccess:^(NSArray *tags) {
for(EDAMTag *tag in tags)
{
if([tag.name isEqualToString:@"ShoppingList"])
{
EDAMNoteFilter* filter = [[EDAMNoteFilter alloc] initWithOrder:0 ascending:NO words:nil notebookGuid:nil tagGuids:[@[tag.guid] mutableCopy] timeZone:nil inactive:NO emphasized:nil];
}
break;
}
} failure:^(NSError *error) {
NSLog(@"tag error : %@",error);
}];
Let me know if there is better way to do this.
