我成功添加SA_OAuthTwitterEngine到我的应用程序中，但遇到了一个非常奇怪的问题。当我登录 Twitter 时，我的应用程序将崩溃：

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

该应用程序崩溃了[_engine sendUpdate:[NSString stringWithFormat:@"This Tweet for testing!"]];。如果我改用[_engine sendUpdate:nil];它，它将不会崩溃，但无法从我的帐户发送推文。

当我试图追踪方法时，我在以下函数的语句中sendUpdate遇到了实际问题，[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];
}

是的，我终于解决了我的问题。我只是替换代码，

- (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;
}

修改 SA_OAuthTwitterEngine.m 函数。我从iOS5 中的 MGTwitterEngine 崩溃中得到了帮助，这个链接。

我正在运行 iOS 6.1.3，我的测试设备是 iPhone 4s。我得到了与 xcode 将崩溃指向[theRequest prepare];方法相同的错误/崩溃。

我的固定是：

        OAMutableURLRequest *theRequest = [[[OAMutableURLRequest alloc]         
                 initWithURL:finalURL
                 consumer:self.consumer
                 token:_accessToken
                 realm: nil
                 signatureProvider:nil] autorelease];

将自动发布放在这条线上并[_engine isAuthorized]在发布推文之前再次检查：

        if ([_engine isAuthorized])
        {
             NSLog(@"post Tweet");
             . . . . . .
        } else {
             NSLog(@"cant post Tweet");
             . . . . . .
        }

我无法进一步解释，因为我还不熟悉这个，但这对我有用。

我对上面的代码进行了更改，因为 twitter api 已更改，所以旧的将无法使用。

对于任何新用户，如果他们使用上述格式和 MGTwitterEnginer，它将不起作用，您需要替换

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"];
