在我的 iPhone 应用程序中，我正在使用 ShareKit 实现 twitter 分享功能。当我尝试在设备中通过 twitter 分享时，应用程序崩溃了

- (void)connectionDidFinishLoading:(NSURLConnection *)aConnection

我收到了错误消息；

NSInvalidArgumentException, [NSCFType tokenRequestTicket:didFinishWithData]:

但它在模拟器上运行良好。而且我之前在另一个应用程序中使用了相同的代码，没有任何更改，它仍然运行良好。问题仅存在于新创建的应用程序中。

请帮忙，如果有人需要更多详细信息，请告诉我。

更新 这些是调用的方法

 - (void)tokenRequest
{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"ShareStarted" object:nil];
    [[SHKActivityIndicator currentIndicator] displayActivity:SHKLocalizedString(@"Connecting...")];
    NSLog(@"Url: %@\n Token: %@ \n Consumer: %@\n Key: %@",requestURL, requestToken, consumer, consumerKey);
    OAMutableURLRequest *oRequest = [[OAMutableURLRequest alloc] initWithURL:requestURL
                                                                   consumer:consumer
                                                                      token:nil   // we don't have a Token yet
                                                                      realm:nil   // our service provider doesn't specify a realm
                                                           signatureProvider:signatureProvider];


    [oRequest setHTTPMethod:@"POST"];

    [self tokenRequestModifyRequest:oRequest];

    OAAsynchronousDataFetcher *fetcher = [OAAsynchronousDataFetcher asynchronousFetcherWithRequest:oRequest
                         delegate:self
                didFinishSelector:@selector(tokenRequestTicket:didFinishWithData:)
                  didFailSelector:@selector(tokenRequestTicket:didFailWithError:)];
    [fetcher start];    
    [oRequest release];
}

- (void)tokenRequestTicket:(OAServiceTicket *)ticket didFinishWithData:(NSData *)data 
{
    if (SHKDebugShowLogs) // check so we don't have to alloc the string with the data if we aren't logging
        SHKLog(@"tokenRequestTicket Response Body: %@", [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease]);

    [[SHKActivityIndicator currentIndicator] hide];
    [[NSNotificationCenter defaultCenter] postNotificationName:@"SharingCancel" object:nil];
    if (ticket.didSucceed) 
    {
        NSString *responseBody = [[NSString alloc] initWithData:data
                                                       encoding:NSUTF8StringEncoding];
        OAToken *aToken = [[OAToken alloc] initWithHTTPResponseBody:responseBody];
        [responseBody release];
        self.requestToken =  aToken;
        [aToken release];       

        [self tokenAuthorize];
    }

    else
        // TODO - better error handling here
        [self tokenRequestTicket:ticket didFailWithError:[SHK error:SHKLocalizedString(@"There was a problem requesting authorization from %@", [self sharerTitle])]];
}

ShareKit将尝试使用导航控制器堆栈到find您的root view controller，然后pop从modal view controller那里。error当它不能时它会抛出这个find。

您可以通过使用以下调用设置correct它：manuallyroot view controller

[SHK setRootViewController:myViewController];

检查答案。
