Hello all,

I've searched the net and documentation, but haven't found anything quite like what I'm trying to do. I'm working on an app where I want to load one view if a UIButton is held for x seconds, another if it's held for x+y seconds, etc. I found this tutorial. The problem I'm running into is, how do I switch the length of the button press? The tutorial switched the number of taps.

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSSet *allTouches = [event allTouches];

    switch ([allTouches count]) 
    {
        case 1: // Single touch
        { 
            // Get the first touch.
            UITouch *touch = [[allTouches allObjects] objectAtIndex:0];

            switch ([touch tapCount])
            {
                case 1: // Single Tap.
                {
                    // Start a timer
                    timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(showAlertView:) userInfo:nil repeats:NO];
                    [timer retain];
                } 
                    break;
                case 2: // Double tap.
                    break;
            }
        } 
            break;
        case 2: // Double touch
        {
        } 
            break;
        default:
            break;
    }

}

Any suggestions?

Thanks! Thomas
