我没有应用程序来测试它，但我已经从this SO question翻译了php-curl解决方案。

    NSString *authCode = [NSString stringWithFormat:@"GoogleLogin auth=",@"ACCESS CODE FROM OAUTH2"];
    NSString *userId = @"USER ID GOES HERE";
    NSString *albumId = @"ALBUM ID GOES HERE";
    NSString *albumUrl = [NSString stringWithFormat:@"https://picasaweb.google.com/data/feed/api/user/%@/albumid/%@",userId, albumId];


    // To get the data from a PNG file
    NSData *postData = UIImagePNGRepresentation([UIImage imageNamed:@"YOUR IMAGE"]);

    // To get the data from a JPEG file
    //NSData *postData = UIImageJPEGRepresentation([UIImage imageNamed:@"YOUR IMAGE"], 0.9f);

    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

    // Init and set fields of the URLRequest
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setHTTPMethod:@"POST"];
    [request setURL:[NSURL URLWithString:[NSString stringWithString:albumUrl]]];
    [request setValue:@"image/jpeg" forHTTPHeaderField:@"Content-Type"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"2" forHTTPHeaderField:@"GData-Version"];
    [request setValue:authCode forHTTPHeaderField:@"Authorization"];
    [request setHTTPBody:postData];

    NSURLResponse* rep = nil;
    NSError *err = nil;
    NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&rep error:&err];

    if (data && !err) {
        //Do something with the response
    }

希望这会有所帮助。
