When using the ‘CABasicAnimation’ from the QuartzCore Framework in Objective-C, you have to specify an animationWithKeyPath.? This is a long string and is not easily listed in the CABasicAnimation, CAPropertyAnimation, or the CAAnimation class.? I ended up finding a handy chart within the Core Animation Programming guide in Apple’s iPhone OS Reference Library.? Hope this helps save someone time, at least it will for me.

      //The following code moves a view up 60 pixels and stops.

CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
theAnimation.delegate = self;
theAnimation.duration = 1;
theAnimation.repeatCount = 0;
theAnimation.removedOnCompletion = FALSE;
theAnimation.fillMode = kCAFillModeForwards;
theAnimation.autoreverses = NO;
theAnimation.fromValue = [NSNumber numberWithFloat:0];
theAnimation.toValue = [NSNumber numberWithFloat:-60];

[self.view.layer addAnimation:theAnimation forKey:@"animateLayer"];
