Answer 1

NSURLConnection is deprecated in iOS 9. You can use NSURLSession instead which exists since iOS 7.

NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
        completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
        {
            // do something with the data 
        }];
[dataTask resume];

Answer 2

It seems that the whole NSURLConnection API has been deprecated in iOS 9. Existing apps will continue to work, but new builds (linked against iOS SDK) must use the newer NSURLSession API.

Ray Wenderlich has a good tutorial here. Also, of course, check the official documentation.

Answer 3

Use STHTTPRequest which uses NSURLConnection/NSURLSession.

For NSURLSession use STHTTPRequest2.

STHTTPRequest is best library as it has only 2 files and easy to use.

Answer 4

If you don't care about the completionHandler : here's an one liner.

[[[NSURLSession sharedSession] dataTaskWithRequest:request] resume];
