これを試してください..これがあなたに役立つことを願っています.
UILabel * m_pLabel = [[UILabel alloc] initWithFrame:CGRectMake(100, 10, 100, 40)];
[m_pLabel setBackgroundColor:[UIColor redColor]];
[self.view addSubview:m_pLabel];
CABasicAnimation * m_pAnimationObj = [CABasicAnimation animationWithKeyPath:@"transform.translation"];
[m_pAnimationObj setFromValue:[NSValue valueWithCGRect:CGRectMake(100, 10, 100, 40)]];
[m_pAnimationObj setToValue:[NSValue valueWithCGRect:CGRectMake(100, 500, 100, 40)]];
m_pAnimationObj.duration = 1.0;
m_pAnimationObj.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
[m_pLabel.layer addAnimation:m_pAnimationObj forKey:@"animations"];

UIView をアニメーション化する方法に関するチュートリアルがたくさんあります: UIView アニメーション チュートリアルの使用方法 ここにも参考になる例があります
//UIViewAnimationOptionAutoreverse option, try the code below:
UIView * testView = [[UIView alloc] initWithFrame:CGRectMake(20.0f, 100.0f, 300.0f, 200.0f)];
[testView setBackgroundColor:[UIColor blueColor]];
[self.view addSubview:testView];
[UIView animateWithDuration:0.3f
delay:0.0f
options:UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse
animations:^{
[testView setFrame:CGRectMake(0.0f, 100.0f, 300.0f, 200.0f)];
}
completion:nil];
[testView release];
