我需要在当月获得可能，但我做不到。我怎样才能做到这一点。
let date = NSDate()
let calendar = NSCalendar.currentCalendar()
let components = calendar.components([.Day , .Month , .Year], fromDate: date)
let year = components.year
let month = components.month
let day = components.day

let now = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "LLLL"
let nameOfMonth = dateFormatter.string(from: now)

If you are using Swift 3.0then extensions and Dateclass are great way to go.
如果您使用的是Swift 3.0，那么扩展和Date类是不错的选择。
try below code
试试下面的代码
extension Date {
var month: String {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MMMM"
return dateFormatter.string(from: self)
}
}
Get work with it like below:
像下面一样使用它：
let date = Date()
let monthString = date.month

You use DateFormatter() see below for this used in an extension to Date.
您使用 DateFormatter() 见下文，用于 Date 的扩展中。
Add this anywhere in your project in global scope.
在全局范围内将其添加到项目中的任何位置。
extension Date {
func monthAsString() -> String {
let df = DateFormatter()
df.setLocalizedDateFormatFromTemplate("MMM")
return df.string(from: self)
}
}
}
Then you can use this anywhere in your code.
然后你可以在你的代码中的任何地方使用它。
let date = Date()
date.monthAsString() // Returns current month e.g. "May"
