以前的向上移动动画

// CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath: @”position”];
// anim.duration = 0.5;
// anim.fromValue = [NSValue valueWithCGPoint:CGPointMake(self.teamLabel.x, self.teamLabel.y + 15)];
// anim.toValue = [NSValue valueWithCGPoint:CGPointMake(self.teamLabel.x, self.teamLabel.y)];
// anim.delegate = self;
// anim.removedOnCompletion = NO;
// anim.fillMode = kCAFillModeForwards;
