How we can Import Images from Evernote in iPhone sdk

I am developing an app which is drawing tool project and we need to import image from evernote account into my app.

I am using below code to get note list. But i am not able to decode "data.bodyHash" NSData and image become nil. You can see in below code.

EvernoteSession *session = [EvernoteSession sharedSession];
EDAMNoteFilter* filter = [[EDAMNoteFilter alloc] initWithOrder:0 ascending:NO words:nil notebookGuid:nil tagGuids:nil timeZone:nil inactive:NO emphasized:nil];
[[EvernoteNoteStore noteStore] findNotesWithFilter:filter offset:0 maxNotes:100 success:^(EDAMNoteList *list) {
    for (EDAMNote *note in list.notes) {
        NSLog(@"Notes : %@",note.title);
        NSMutableArray *resources = note.resources;
        if (resources!=nil) {
            EDAMResource* resource = [resources objectAtIndex:0];
            EDAMData *data = resource.data;
            UIImage *image = [[UIImage alloc]initWithData:data.bodyHash];
            /// Image is nil
        }
    }
}

Thanks

Yes, it's possible. There are steps you should take to achieve the desired result.

1) Ensure that your Evernote Application has full access to user's Evernote account to able to read existing notes (you can set this up when requesting Evernote API Key on https://dev.evernote.com )

2) Authenticate

[self.session authenticateWithViewController:self
                          preferRegistration:NO
                                  completion:^(NSError* authenticateError) {
  ...
}];

3) Find all notes

[self.session findNotesWithSearch:nil
                       inNotebook:nil
                          orScope:ENSessionSearchScopeAll
                        sortOrder:ENSessionSortOrderNormal
                       maxResults:255
                       completion:^(NSArray* findNotesResults,
                                    NSError* findNotesError) {
  ...
}];

4) Download each note

for (ENSessionFindNotesResult* result in findNotesResults) {
  [self.session downloadNote:result.noteRef
                    progress:NULL
                  completion:^(ENNote* note,
                               NSError* downloadNoteError) {
    ...
  }];
}

5) Get all images

for (ENResource* resource in note.resources) {
  if ([resource.mimeType hasPrefix:@"image"]) {
    UIImage* image = [[UIImage alloc] initWithData:resource.data];
    ...
  }
}

You can check sample project here.
If you set consumer key and secret, after authentication you'll see similar console output:
