この方法でHTTPリクエストを作成しようとしています:

 NSString *urlString = [NSString stringWithFormat:@"https://api.dropbox.com/1/oauth/request_token"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

//set headers
NSString *contentType = [NSString stringWithFormat:@"text/xml"];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];

 oauth_version="1.0"
oauth_signature_method="PLAINTEXT"
oauth_consumer_key="<app-key>"
oauth_signature="<app-secret>&"

//create the body
NSMutableData *postBody = [NSMutableData data];
[postBody appendData:[[NSString stringWithFormat:@"<xml>"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:@"<yourcode/>"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:@"</xml>"] dataUsingEncoding:NSUTF8StringEncoding]];

//post
[request setHTTPBody:postBody];

//get response
NSHTTPURLResponse* urlResponse = nil;  
NSError *error = [[NSError alloc] init];  
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];  
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(@"Response Code: %d", [urlResponse statusCode]);
if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) {
    NSLog(@"Response: %@", result);

    //here you get the response

}

これらのヘッダーを使用してリクエストを作成しようとしています:

Authorization: OAuth oauth_version="1.0", oauth_signature_method="PLAINTEXT", oauth_consumer_key="<app-key>", oauth_signature="<app-secret>&"

しかし、私は方法を理解できません。助けてください！！

The authorization in your case is just a HTTP header. So it's:

[request addValue:@"OAuth oauth_version=\"1.0\", oauth_signature_method=\"PLAINTEXT\", oauth_consumer_key=\"<app-key>\", oauth_signature=\"<app-secret>&\"" forHTTPHeaderField: @"Authorization"];

Or:

NSString* oauth_version=@"1.0";
NSString* oauth_signature_method=@"PLAINTEXT";
NSString* oauth_consumer_key=@"<app-key>";
NSString* oauth_signature=@"<app-secret>&";
NSString* authHeader = [NSString stringWithFormat: @"OAuth oauth_version=\"%@\", oauth_signature_method=\"%@\", oauth_consumer_key=\"%@\", oauth_signature=\"%@\"",
    oauth_version, oauth_signature_method, oauth_consumer_key, oauth_signature];

このすべてにコメントしてみてください

//NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];  
//NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
//NSLog(@"Response Code: %d", [urlResponse statusCode]);
//if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) {
   // NSLog(@"Response: %@", result);

    //here you get the response

//}

上記のすべての代わりにこれを使用してください

 NSURLConnection *conn = [NSURLConnection connectionWithRequest:request delegate:self];

これらのデリゲート機能を実装する

注-self.dataは、ヘッダーのデータとして宣言されたNSMUtableDataオブジェクトです。

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    [self.data setLength:0];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)d {
    [self.data appendData:d];
}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    [[[[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Error", @"")
                                 message:[error localizedDescription]
                                delegate:nil
                       cancelButtonTitle:NSLocalizedString(@"OK", @"") 
                       otherButtonTitles:nil] autorelease] show];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {


    NSString *responseText = [[NSString alloc] initWithData:self.data encoding:NSUTF8StringEncoding];

    // Do anything you want with it 
    [responseText release];
}

// Handle basic authentication challenge if needed
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {

//I'm using HTTP Digest Authentication in your case it could be different
    NSURLCredential *credential = [NSURLCredential credentialWithUser:HTTP_DIGEST_USER
                                                             password:HTTP_DIGEST_PASSWORD
                                                          persistence:NSURLCredentialPersistenceForSession];
    [[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
}

それが役立つことを願っています

このエラーは、間違ったバンドルまたはドキュメントディレクトリパスをメディアに渡した場合に発生します。HTTPリクエスト本文へのメディアパスを確認するだけです。
