尝试连接ios中的twitter时应用程序崩溃

在我的iPhone应用程序中，我正在使用ShareKit实现twitter共享功能。当我试图通过设备上的twitter分享时，该应用程序崩溃在尝试连接ios中的twitter时应用程序崩溃

- (void)connectionDidFinishLoading:(NSURLConnection *)aConnection

而我收到错误消息;

NSInvalidArgumentException, [NSCFType tokenRequestTicket:didFinishWithData]:

但它在模拟器上运行良好。我之前使用了相同的代码，而在另一个应用程序中没有任何更改，并且它仍然运行良好。该问题只在新创建的应用程序中。

请帮忙，如果有人需要更多的细节请让我知道。

更新这些称为

- (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])]]; 
}

提供有关如何ü执行更多的信息 - （空）connectionDidFinishLoading：（NSURLConnection的*）aConnection ... – lakesh

我加入了一些代码，请检查。 – Mithuzz

ShareKit将尝试使用导航控制器堆栈find您root view controller方法，那么pop一个modal view controller从那里。它抛出这个error，当它不能find之一。

您可以通过manuallycorrect它通过使用下面的调用设置root view controller：

[SHK setRootViewController:myViewController];

检查answer。

我试图通过在链接的答案中使用[SHK setRootViewController：myViewController]，但仍然是相同的错误。 – Mithuzz

而且它在模拟器中工作正常，问题只在设备中。 – Mithuzz
