I was wondering if anyone had any information of code that they have used to upload an image to Picasa. I really only need the code to upload images, I have everything working to get the image feed and view it, but going the other way is giving me a problem.
Google does not really provide any good documentation for how to do this. Any help would be greatly appreciated.
Check this code:
GDataServiceGooglePicasaWeb* service =
[[GDataServiceGooglePicasaWeb alloc] init];
[service setUserCredentialsWithUsername:@"[email protected]"
password:@"mypasswd"];
// get the URL for the album
NSURL *albumURL = [GDataServiceGooglePicasaWeb
picasaWebFeedURLForUserID:@"my.account" albumID:nil
albumName:@"MyBestPhotos" photoID:nil kind:nil access:nil];
// set a title and description for the new photo
GDataTextConstruct *title, *desc;
title = [GDataTextConstruct textConstructWithString:@"Sunset Photo"];
desc = [GDataTextConstruct textConstructWithString:@"A nice day"];
GDataEntryPhoto *newPhoto = [GDataEntryPhoto photoEntry];
[newPhoto setTitle:title];
[newPhoto setPhotoDescription:desc];
// attach the photo data
NSData *data = [NSData dataWithContentsOfFile:@"/SunsetPhoto.jpg"];
[newPhoto setPhotoData:data];
[newPhoto setPhotoMIMEType:@"image/jpeg"];
// now upload it
GDataServiceTicket *ticket;
ticket = [service fetchPicasaWebEntryByInsertingEntry:newPhoto
forFeedURL:albumURL
delegate:self
didFinishSelector:@selector(addPhotoTicket:finishedWithEntry:)
didFailSelector:@selector(addPhotoTicket:failedWithError:)];
