Trying to get some basic drag/drop functionality happening for an iPhone application.

My current code for trying to do this is as follows:

- (void) touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event
{
    UITouch *touch = [touches anyObject];

    CGPoint location = [touch locationInView:self];
    self.center = location;
}

This code has the result of a the touched UIView flickering while it follows the touch around. After playing around with it a bit, I also noticed that the UIView seemed to flicker from the 0,0 position on the screen to the currently touched location.

Any ideas what I'm doing wrong?
