在 xcode 仪器中，我遇到此方法内存泄漏

- (void)getDataForRequest:(NSURLRequest *)request completionHandler:(downloadCompletionBlock)completionHandler
{
    self.expectedLength = 0;
    self.currentLength = 0;
    self.responseData = Nil;
    
    self.contentLengthBlock = nil;
    self.completionBlock = completionHandler;
    
    NSURLSession *session = [NSURLSession sharedSession];
    
    NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
    
    session = [NSURLSession sessionWithConfiguration:defaultConfigObject delegate: self delegateQueue: [NSOperationQueue mainQueue]];
    
    self.postDataTask = [session dataTaskWithRequest:request];
    
    [self.postDataTask resume];
}
