Question

我正在使用TWRequest向Twitter发布回复（使用“in_reply_to_status_id”），由于某种原因，TWRequest正在崩溃。

因此，如果用户提供了回复ID，则：

  if(replyID){
     paramDict = [NSDictionary dictionaryWithObjectsAndKeys: replyID, @"in_reply_to_status_id", tweet, @"status", nil];
}
    else
         paramDict = [NSDictionary dictionaryWithObject:tweet forKey:@"status"];

  postRequest = [[TWRequest alloc] initWithURL:
  [NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"] 
       parameters: paramDict requestMethod:TWRequestMethodPOST];



  // Post the request
[postRequest setAccount:myAccount];

// Block handler to manage the response
[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) 
//                     [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) 


{

NSDictionary *responseDict = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];

                      NSLog(@"Twitter response, HTTP response: %i with Error: %@", [urlResponse statusCode], [error localizedDescription]);
                      NSLog(@"response: %@", responseDict);

                      if([urlResponse statusCode] == 200){

                          if([delegate respondsToSelector:@selector(sendTweetSuccess)]){
                              [delegate sendTweetSuccess];
                          }
                      }
                      else{

                          if([delegate respondsToSelector:@selector(sendTweetFailed:)]){
                              [delegate sendTweetFailed:error];
                          }
                      }
                  }];
}

我的崩溃指向了这个：

[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)

崩溃：

如果我不提供replyID，这可以正常工作。谢谢你的帮助。

看起来你正在发送NSNumber，但TWRequest期望所有参数都是NSString。
