Question

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...
}
