Question

When I tap a button it will invoke an action which in-turn will initiate a process(through another method) and return. I thought of using

[<target> performSeleltorInBackgroundThread:....];

-but I could not pass multiple arguments through this.

How can I achieve it.

You can do it like this:

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    [self goDoSomethingLongAndInvolved:arg1 and:arg2 and:arg3 and:argN];
    dispatch_async(dispatch_get_main_queue(), ^{
        [textField setStringValue:@"Done doing something long and involved - Update UI"];
    });
});
