Execute task in background

In my app after user press start button I execute some code in for cycle. How to keep application responsible for user interaction during this? In C# there is BackgroundWorker class, is there anything similar in IOS?

You can use selector like this: 

[self performSelectorInBackground:@selector(yourForCycle:) withObject:nil];


-(void)yourForCycle:(id)sender {

    //Your for cycle...
}

use gcd like following

dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^  {  
   //Put your heavy code here it will not block the user interface
});
