アプリに正常に追加SA_OAuthTwitterEngineしましたが、非常に奇妙な問題が発生しました。Twitter にログインすると、次のようにアプリがクラッシュします。

- (void) OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername: (NSString *) username 
{
    [_engine sendUpdate:[NSString stringWithFormat:@"This Tweet for testing!"]];
    NSLog(@"Authenicated for %@", username);
}

でアプリがクラッシュし[_engine sendUpdate:[NSString stringWithFormat:@"This Tweet for testing!"]];ます。代わりに使用[_engine sendUpdate:nil];すると、クラッシュせずに動作しますが、アカウントからツイートを送信できません。

メソッドをトレースしようとすると、次の関数のステートメントでsendUpdate実際の問題が発生しました。[theRequest prepare];

- (NSString *)_sendRequestWithMethod:(NSString *)method path:(NSString *)path queryParameters:(NSDictionary *)params body:(NSString *)body requestType:(MGTwitterRequestType)requestType responseType:(MGTwitterResponseType)responseType
{
    NSString *fullPath = path;
    NSString *urlString = [NSString stringWithFormat:@"%@://%@/%@", (_secureConnection) ? @"https" : @"http", _APIDomain, fullPath];
    NSURL *finalURL = [NSURL URLWithString:urlString];
    if (!finalURL) {
        return nil;
    }
OAMutableURLRequest *theRequest = [[OAMutableURLRequest alloc] initWithURL:finalURL consumer:self.consumer  token:_accessToken realm: nil signatureProvider:nil];
    if (method) {
        [theRequest setHTTPMethod:method];
    }
    [theRequest setHTTPShouldHandleCookies:NO];

    // Set headers for client information, for tracking purposes at Twitter.
    [theRequest setValue:_clientName    forHTTPHeaderField:@"X-Twitter-Client"];
    [theRequest setValue:_clientVersion forHTTPHeaderField:@"X-Twitter-Client-Version"];
    [theRequest setValue:_clientURL     forHTTPHeaderField:@"X-Twitter-Client-URL"];

    // Set the request body if this is a POST request.
    BOOL isPOST = (method && [method isEqualToString:@"POST"]);
    if (isPOST) {
        // Set request body, if specified (hopefully so), with 'source' parameter if appropriate.
        NSString *finalBody = @"";
        if (body) {
            finalBody = [finalBody stringByAppendingString:body];
        }
        if (_clientSourceToken) {
            finalBody = [finalBody stringByAppendingString:[NSString stringWithFormat:@"%@source=%@", (body) ? @"&" : @"?" , _clientSourceToken]];
        }

        if (finalBody) {
            [theRequest setHTTPBody:[finalBody dataUsingEncoding:NSUTF8StringEncoding]];
        }
    }
    [theRequest prepare];

    // Create a connection using this request, with the default timeout and caching policy, 
    // and appropriate Twitter request and response types for parsing and error reporting.
    MGTwitterHTTPURLConnection *connection;
    connection = [[MGTwitterHTTPURLConnection alloc] initWithRequest:theRequest delegate:self requestType:requestType responseType:responseType];

    if (!connection) {
        return nil;
    } else {
        [_connections setObject:connection forKey:[connection identifier]];
    }

    return [connection identifier];
}

はい、ついに私は私の問題を解決します。i コードを置き換えるだけで、

- (SA_OAuthTwitterEngine *) initOAuthWithDelegate: (NSObject *) delegate 
  {

    if (self = (id) [super initWithDelegate: delegate]) {
       self.requestTokenURL = [NSURL URLWithString: @"https://twitter.com/oauth/request_token"];
       self.accessTokenURL = [NSURL URLWithString: @"https://twitter.com/oauth/access_token"];
       self.authorizeURL = [NSURL URLWithString: @"https://twitter.com/oauth/authorize"];
     }
  return self;
}

SA_OAuthTwitterEngine.m 関数を変更します。iOS5 での MGTwitterEngine のクラッシュ、このリンクから助けを得ました。

上記のコードに変更を加えました。Twitter の API が変更されたため、古い API が機能しなくなりました。

新規ユーザーが MGTwitterEngine で上記の形式を使用している場合、それは機能しません。置き換える必要があります。

self.requestTokenURL = [NSURL URLWithString: @"https://api.twitter.com/oauth/request_token"]; self.accessTokenURL = [NSURL URLWithString: @"https://api.twitter.com/oauth/access_token"]; self.authorizeURL = [NSURL URLWithString: @"https://api.twitter.com/oauth/authorize"];
