OC中AFNetworing设置超时时间,但实际运行超时时间与设置参数不符

Question

运行环境为Xcode7.0,iOS9.0,AFNetworking~> 2.5.0,为了用户在网速慢情况下上次照片等待45秒后提示用户上次超时.
与超时时间设置有关的代码为:
// 设置超时时间
[manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
manager.requestSerializer.timeoutInterval = 45.f;
[manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];
实际运行时,如果我设置超时为5s,实际会在13秒左右报超时错误,设置45s,1分多钟也不见超时.而且AFNetworking默认超时为60s,但在不更改其超时时间的情况下,也是1分多钟才超时甚至一直不超时就在那上传图片.

附上整个网络请求的代码:
我们对AFNetworking进行了二次封装
/**

• 用户上传修改自己的Banner
• @param userID 用户ID
• @param banner banner
• @param success 成功block

• @param failed 失败block
  */

  • (void)userPostBannerWithUserID:(NSString *)userID withBanner:(NSData *)data success:(Success)success failed:(Failure)failure { NSString *url = [NSString stringWithFormat:@"%@%@",kBaseURL,@"/account/user/banner"]; NSDictionary *parms = @{@"banner":data,@"user_id":userID}; [CRHttpTool httpToolRequestWithBaseURL:url params:parms success:^(id json) { success(json); } failure:^(NSError *error) { failure(error); MyLog(@"%@",error.description);

  } method:@"POST"];
  }

#pragma mark --- 私有方法
/**

• 像服务器发送请求，不带请求头
• @param urlString 请求完整url路径
• @param params 请求参数
• @param success 成功block

• @param method 请求方法（POST,GET）
  */

  • (void)httpToolRequestWithBaseURL:(NSString *)urlString params:(NSDictionary *)params success:(Success)success failure:(Failure)failure method:(NSString *)method { AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; AFHTTPRequestOperation * operation =nil;

  // 设置超时时间
  [manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
  manager.requestSerializer.timeoutInterval = 45.f;
  [manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];
  manager.requestSerializer.cachePolicy = NSURLRequestReturnCacheDataElseLoad;

  //GET请求
  NSComparisonResult comparison1 = [method caseInsensitiveCompare:@"GET"];
  if (comparison1 == NSOrderedSame) {
  operation =[manager GET:urlString
  parameters:params
  success:^(AFHTTPRequestOperation *operation,id responseObject) {
  success(responseObject);
  }failure:^(AFHTTPRequestOperation *operation,NSError *error) {
  failure(error);
  }];

  //POST请求
  NSComparisonResult comparison2 = [method caseInsensitiveCompare:@"POST"];
  if (comparison2 == NSOrderedSame) {

  BOOL isFile = NO;
  for (NSString *key in params.allKeys) {
      id value = params[key];
      if ([value isKindOfClass:[NSData class]]) {
          isFile = YES;
          break;
      }
  }
  
  //不包含文件数据
