Integrating twitpic OAuth for iPhone.
- by asadqamber
How can I integrate twitpic API with OAuth for posting an image from iPhone? Any help or tutorial? Currently I am doing...
NSURL *twitpicURL = [NSURL URLWithString:@"http://api.twitpic.com/2/upload.format"];
theRequest = [NSMutableURLRequest requestWithURL:twitpicURL];
[theRequest setHTTPMethod:@"POST"];
// Set the params
NSString *message = theMessage;
[theRequest addValue:@"http://api.twitter.com/" forHTTPHeaderField:@"OAuth realm"];
[theRequest addValue:TWITPIC_API_KEY forHTTPHeaderField:@"oauth_consumer_key"];
[theRequest addValue:@"HMAC-SHA1" forHTTPHeaderField:@"oauth_signature_method"];
[theRequest addValue:USER_OAUTH_TOKEN forHTTPHeaderField:@"oauth_token"];
[theRequest addValue:USER_OAUTH_SECRET forHTTPHeaderField:@"oauth_secret"];
[theRequest addValue: @"1272325550" forHTTPHeaderField:@"oauth_timestamp"];
[theRequest addValue:nil forHTTPHeaderField:@"oauth_nonce"];
[theRequest addValue:@"1.0" forHTTPHeaderField:@"oauth_version"];
[theRequest addValue:nil forHTTPHeaderField:@"oauth_signature"];
NSMutableData *postBody = [NSMutableData data];
[postBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"source\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:@"lighttable"] dataUsingEncoding:NSUTF8StringEncoding]];
// Message
[postBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"message\"\r\n\r\n%@", message]dataUsingEncoding:NSUTF8StringEncoding]];
// Media
[postBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"media\"; filename=\"%@\"\r\n", @"doc_twitpic_image.jpg"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:@"Content-Type: image/jpg\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; // data as JPEG
[postBody appendData:[[NSString stringWithFormat:@"Content-Transfer-Encoding: binary\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[NSData dataWithData:image]];
[theRequest setHTTPBody:postBody];
[theRequest setValue:[NSString stringWithFormat:@"%d", [postBody length]] forHTTPHeaderField:@"Content-Length"];
theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
