二元运算符＆＃39; |＆＃39;无法应用于两个UIViewAutoresizing操作数

Question

在Swift 2.0中获取此错误。

  

二元运算符＆＃39; |＆＃39;不能应用于两个UIViewAutoresizing操作数

以下是代码：

let view = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568))
addSubview(view)
view.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight

知道可能是什么问题吗？

Answer 1

OptionSetType获得了Swift 2.x的更新语法和Swift 3.x的另一个更新

Swift 3.x

view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

Swift 2.x

view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]

Answer 2

这是Swift 1.2和2之间的区别：

// swift 1.2
view.autoresizingMask = .FlexibleWidth | .FlexibleTopMargin

// swift 2
view.autoresizingMask = [.FlexibleWidth, .FlexibleTopMargin]

Answer 3

尝试使用xcode7-b6：

view.autoresizingMask = UIViewAutoresizing.FlexibleWidth.union(UIViewAutoresizing.FlexibleHeight)

Answer 4

Swift 3 Xcode 8 b1：

view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

Answer 5

实际上是swift 3.0.2：

view.autoresizingMask = [.layerWidthSizable, .layerHeightSizable]

Answer 6

将此代码swift 2与Xcode 7.2一起使用

self.view.autoresizingMask = [.FlexibleRightMargin, .FlexibleLeftMargin, .FlexibleBottomMargin, .FlexibleTopMargin]
