NSURLSession memory leak

Question

Even after invalidate a NSURLSession, running a profile using Instruments, some classes (probably privates) called TubeManager, HTTPConnectionCache and HTTPConnectionCacheDi

Answer 1

finishTasksAndInvalidate called in wrong place... completionHandler is for handling response it has nothing to do with session

Here is correct code:

NSURLSessionConfiguration* config = [NSURLSessionConfigurationdefaultSessionConfiguration];
NSURLSession* session = [NSURLSession sessionWithConfiguration:config];
NSURLRequest* request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]];
NSURLSessionDataTask* sessionDataTask = [session dataTaskWithRequest:request
                                           completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
   // handle response...
}];
[sessionDataTask resume];
[session finishTasksAndInvalidate];
