Send sendSynchronousRequest using NSURLConnection

When we create an NSURLConnection and send sendAsynchronousRequest and application get stuck or hang. So its a synchronous method – i.e. it runs on the Main Thread. Therefore, your application will hang – and it’ll wait till the data is downloaded.To prevent it: use the sendAsynchronousRequest method. It’ll run this process on a background thread and won’t disrupt your application or simply – won’t make it hang. how to use : –

NSURL *url = [NSURL URLWithString:@"YOUR_URL_HERE"];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];

[NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
{
    //the NSData in the completion handler is where your data is downloaded.
}];

NSURL *url = [NSURL URLWithString:@"YOUR_URL_HERE"];

NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];

NSOperationQueue *queue = [[NSOperationQueue alloc] init];

[NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)

{

//the NSData in the completion handler is where your data is downloaded.

}];
