DataFormatterStyle没有成员.mediumStyle

Question

在闭包中我想设置日期和时间的样式,

private let dateFormatter: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateStyle = .mediumStyle
    formatter.timeStyle = .shortStyle
    return formatter
}()

但得到这样的错误

Type 'DataFormatterStyle has no member .mediumStyle'

以前用NSDateFormatter工作得很好

查看文档DateFormatter.Style.你的代码应该是:

private let dateFormatter: DateFormatter = {
    let formatter = DateFormatter()
    formatter.dateStyle = .medium
    formatter.timeStyle = .short
    return formatter
}()

几乎所有在Swift 3中都发生了变化.
