Q:

Do something after a certain time after button clicked

I am trying to have an object disappear from the view after a certain time after a button is tapped.  I'm a little confused with how to get the object to do something a certain after its tapped. I am not sure if I should use a run loop or NSTimer, and even if I know what to use Im still confused on  what to do to make something happen a certain time after the button is tapped.

A:

In your button pressed method you can use:
[self performSelector:@selector(myMethod) withObject:nil afterDelay:3];

And declare method with logic you want to run:
-(void) myMethod
{
    //TODO: your logic goes here
}

You can even pass parameter to your method if you want (withObject argument).
