【已解决】swift代码警告：NSYearCalendarUnit was deprecated in iOS 8.0 Use NSCalendarUnitYear instead

【背景】

xcode中代码编译出错：

swift:80:56: ‘NSYearCalendarUnit’ was deprecated in iOS 8.0: Use NSCalendarUnitYear instead

如图：

【解决过程】

1.搜：

swift NSYearCalendarUnit was deprecated in iOS 8.0 Use NSCalendarUnitYear instead

看起来是api更新，旧的过期了。

2.所以去网上搜搜，

swift NSYearCalendarUnit was deprecated in iOS 8.0 Use NSCalendarUnitYear instead

参考：

xcode – NSYearCalendarUnit deprecated in iOS – Stack Overflow

去换用

NSCalendarUnitYear

去试试。

3.然后通过，按住alt后，点击 NSCalendarUnit，进去看了源码：

public struct NSCalendarUnit : OptionSetType {
    public init(rawValue: UInt)
   
    public static var Era: NSCalendarUnit { get }
    public static var Year: NSCalendarUnit { get }
    public static var Month: NSCalendarUnit { get }
    public static var Day: NSCalendarUnit { get }
    public static var Hour: NSCalendarUnit { get }
    public static var Minute: NSCalendarUnit { get }
    public static var Second: NSCalendarUnit { get }
    public static var Weekday: NSCalendarUnit { get }
    public static var WeekdayOrdinal: NSCalendarUnit { get }
    @available(iOS 4.0, *)
    public static var Quarter: NSCalendarUnit { get }
    @available(iOS 5.0, *)
    public static var WeekOfMonth: NSCalendarUnit { get }
    @available(iOS 5.0, *)
    public static var WeekOfYear: NSCalendarUnit { get }
    @available(iOS 5.0, *)
    public static var YearForWeekOfYear: NSCalendarUnit { get }
    @available(iOS 5.0, *)
    public static var Nanosecond: NSCalendarUnit { get }
    @available(iOS 4.0, *)
    public static var Calendar: NSCalendarUnit { get }
    @available(iOS 4.0, *)
    public static var TimeZone: NSCalendarUnit { get }

很明显，没有那些

NSCalendarUnitYear

之类但，直接都改为对应的变量，即可。

改为：

        let calendar:NSCalendar = NSCalendar.currentCalendar()
        let unitFlags:NSCalendarUnit = [NSCalendarUnit.Year, NSCalendarUnit.Month, NSCalendarUnit.Day, NSCalendarUnit.Hour, NSCalendarUnit.Minute]

即可。

4.另外也看到：

Questions about NSCalendar | Apple Developer Forums

也是这么说的。。

【总结】

‘NSYearCalendarUnit’ was deprecated in iOS 8.0: Use NSCalendarUnitYear instead

很明显是API更新，NSYearCalendarUnit换成NSCalendarUnitYear了。

结果是，再去把对应的域，修改为对应的，符合对应的库里面的内容：

比如，NSCalendarUnit.Month，即可。
