MonthYearPickerView 库 Swift 2.0 问题

Question

我在我的项目中使用 MonthYearPickerView 库，它在 Swift 1.2 中运行很好，现在我正在尝试将其转换为 Swift 2.0 和我遇到了一些问题。

我在注释代码下将日历组件更改为下面的代码，但是当我尝试追加或减去年份值时遇到问题 Cannot convert value of type 'NSDateComponents' to expected argument type 'Int'。那么请问我该如何解决这个问题？

class MonthYearPickerView: UIPickerView, UIPickerViewDelegate, UIPickerViewDataSource {

    override init(frame: CGRect) {
    var years: [Int] = []
    if years.count == 0 {

        //var year = NSCalendar(identifier: NSCalendarIdentifierGregorian)!.component(.CalendarUnitYear, fromDate: NSDate())

        let calendar = NSCalendar.currentCalendar()
        var year = calendar.components(.Year, fromDate:NSDate())

        for i in 1...10 {
            years.append(year)
            year++
        }
    }
    self.years = years

    super.init(frame: frame)

    self.delegate = self
    self.dataSource = self

    //var month = NSCalendar(identifier: NSCalendarIdentifierGregorian)!.component(.CalendarUnitMonth, fromDate: NSDate())

    let calendar = NSCalendar.currentCalendar()
    let month = calendar.components(.Month, fromDate:NSDate())

    self.selectRow(month-1, inComponent: 0, animated: false)
    }

Answer 1

使用 component 函数而不是 components: var year = calendar.component(.Year, fromDate:NSDate())

或 var year = calendar.components(.Year, fromDate:NSDate()).year
