以解决，删除了storyboard，用纯代码实现就没问题了。

更新:
func scrollViewWillEndDragging(scrollView: UIScrollView!, withVelocity velocity: CGPoint, targetContentOffset: UnsafePointer<CGPoint>) {
if scrollView.contentOffset.x > someValue {
targetContentOffset.memory.x = -20
scrollView.setContentOffset( CGPointMake( -20.0 , 0.0 ), animated: false )
}
}
}
实现了自动滑动，但是当animated变成true的时候自动滑动失败了
