This might get you started..

(i have used 0.5 for a timeout value, but you might want to change this)

    -(void)butonEvent:(id)sendr{


    if(buttonTimer)[self doublePress];
    else
    {

    //buttonTimer is a local NSTimer

    buttonTimer = [NSTimer scheduledTimerWithTimeInterval: 0.5
                     target: self
                     selector: @selector(handleTimer:)
                     userInfo: nil
                     repeats: NO];
    }

    }


    -(void)singlePress{
[buttonTimer invalidate];buttonTimer=nil;//edit
    NSLog(@"Single Press");
    }

    -(void)doublePress{
[buttonTimer invalidate];buttonTimer=nil;//edit
    NSLog(@"doublePress");
    }

    -(void)handleTimer:(id)sendr
    {        
    [self singlePress];
    }

There is two options in UIButton Events,

You can use the following to detect, single touch through TouchDown, double touch through TouchDownRepeat. You can connect ur UIButtons using IB same way as like TouchUpInside and write ur coding accoring to that.
