Memory warning while downloading file with AFNetworking

Update:

I wrote a very simple download code:

NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString  *documentsDirectory = [paths objectAtIndex:0];

NSURLRequest* request = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://xxxx.s3.amazonaws.com/products/ipad/xxxx.mp4"]];
for(int i=0; i<4; i++){
    NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,[NSString stringWithFormat:@"xxxx%d.mp4",i]];
    AFDownloadRequestOperation* operation = [[AFDownloadRequestOperation alloc] initWithRequest:request targetPath:filePath shouldResume:YES];
    operation.outputStream = [NSOutputStream outputStreamToFileAtPath:filePath append:NO];
    [operation setShouldOverwrite:YES];
    [operation setProgressiveDownloadProgressBlock:^(AFDownloadRequestOperation *operation, NSInteger bytesRead, long long totalBytesRead, long long totalBytesExpected, long long totalBytesReadForFile, long long totalBytesExpectedToReadForFile) {
        NSLog(@"%f", ( totalBytesRead / (float)totalBytesExpected));
    }];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"finished");
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(error.description);
    }];
    [[NSOperationQueue mainQueue] addOperation:operation];
}

I wrote it in my projects viewDidLoad commenting out all other codes. Memory usage is still the same and increasing:

I created a new project, and I wrote exactly the same code in the new project. And the memory usage is:

Which is good. But I don't understand why it is different in the real project?

I guess you open the zombie mode. Product -> Scheme -> Edit Scheme
Uncheck the opition [Enable Zombie Object]

This is awkward. I created a new project, and copy the same code, and it is working without memory warning. Download operation doesn't effect the memory. I didn't understand the problem. Maybe because of the project settings.
