iOS AFNetworking downloadProgressBlock расчет возврата отрицательных чисел
Я использую AFNetworking для загрузки данных, которые анализируются сторонним классом. Я использовал AFNetworking, чтобы выполнять подобные действия много раз, но по какой-то причине, когда я вызываю downloadProgressBlock и выполняю вычисления для использования с моим индикатором выполнения, числа возвращаются отрицательными. Смотри ниже:

Ниже мой код:
// Get the URL we are going to use to parse with
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://www.portlandonline.com/scripts/911incidents.cfm"]];
NSURLRequest *request = [httpClient requestWithMethod:@"GET" path:nil parameters:nil];
AFHTTPRequestOperation *operation = [httpClient HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"Response = %@", operation);
// Empty our calls out
[self.originalArray removeAllObjects];
// Initiate our parser
MWFeedParser *parser = [[MWFeedParser alloc] init];
parser.delegate = self;
[parser startParsingData:responseObject textEncodingName:[operation.response textEncodingName] withCompletionHandler:^(NSError *error, MWFeedParser *parser) {
// If theres no error
if (!error) {
// Return the success block
success(operation.request, operation.request.URL, self.calls);
}
else {
// Return the failure block
failure(operation.request, operation.request.URL, error);
}
}];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"AFHTTPRequestOperation Failure: %@", error);
// Return our failure block
failure(operation.request, operation.request.URL, error);
}];
[operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
NSLog(@"Download = %f", (float)totalBytesRead / totalBytesExpectedToRead);
}];
[operation start];
