UIViewAnimationOptions.fromMask（）发生了什么，新的替代方案是什么？

Question

例如：

let curve : AnyObject? = info[UIKeyboardAnimationCurveUserInfoKey]

UIView.animateWithDuration(duration, delay: 0, options: UIViewAnimationOptions.fromMask(curve), animations: { self.tableView.contentInset = UIEdgeInsetsMake(0.0, 0.0, kbFrame.height - self.heightView.frame.height, 0.0) }, completion: { (value: Bool) in println() })

现在.fromMask()消失了，我该怎么办？

Answer 1

我明白了。

请改用UIViewAnimationOptions(rawValue: curve)。请确保（在我的示例中）将曲线转换为(info[UIKeyboardAnimationCurveUserInfoKey] as NSValue) as UInt
