iOS Swift将日历组件int月份转换为中等样式的字符串月份
iOS Swift将日历组件int月份转换为中等样式的字符串月份
提问于 2015-06-12 06:06:10
我想以这种格式显示日历
给用户。一种选择是使用"string range“来获取各个日历组件。第二种方法是使用NSCalendar获取它，这在我看来是更好的(是吗？)。所以我的代码如下所示。但有两个问题。
- I‘m’t Int the local time form "hour & minute“
- I‘m Int in Int. (我没有得到当地时间”小时和分钟组件“)。我希望它是字符串(mediumStyle中的月份)
有人知道怎么弄到我需要的东西吗？所附图片正是我想要达到的目标。在这里，我使用了三个UILabel，一个表示“日期”，第二个表示“月、年”，第三个表示“时间”。
任何帮助都将不胜感激。
var inputDateString = "Jun/12/2015 02:05 Am +05:00"
override func viewDidLoad() {
super.viewDidLoad()
let newDate = dateformatterDateString(inputDateString)
let calendar = NSCalendar.currentCalendar()
let components = calendar.components(.CalendarUnitHour | .CalendarUnitMinute | .CalendarUnitMonth | .CalendarUnitYear | .CalendarUnitDay, fromDate: newDate!)
let hour = components.hour
let minutes = components.minute
let month = components.month
let year = components.year
let day = components.day
println(newDate)
println(components)
println(day) // 12
println(month) // 6 -----> Want to have "Jun" here
println(year) // 2015
println(hour) // 2 ------> Want to have the hour in the inputString i.e. 02
println(minutes) // 35 ------> Want to have the minute in the inputString i.e. 05
}
func dateformatterDateString(dateString: String) -> NSDate? {
let dateFormatter: NSDateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MMM/dd/yyyy hh:mm a Z"
// dateFormatter.timeZone = NSTimeZone(abbreviation: "UTC")
dateFormatter.timeZone = NSTimeZone.localTimeZone()
return dateFormatter.dateFromString(dateString)

您可以按如下方式使用DateFormatter：
extension Formatter {
static let monthMedium: DateFormatter = {
let formatter = DateFormatter()
formatter.dateFormat = "LLL"
return formatter
}()
static let hour12: DateFormatter = {
let formatter = DateFormatter()
formatter.dateFormat = "h"
return formatter
}()
static let minute0x: DateFormatter = {
let formatter = DateFormatter()
formatter.dateFormat = "mm"
return formatter
}()
static let amPM: DateFormatter = {
let formatter = DateFormatter()
formatter.dateFormat = "a"
return formatter
}()
}
extension Date {
var monthMedium: String { return Formatter.monthMedium.string(from: self) }
var hour12: String { return Formatter.hour12.string(from: self) }
var minute0x: String { return Formatter.minute0x.string(from: self) }
var amPM: String { return Formatter.amPM.string(from: self) }
}let date = Date()
let dateMonth = date.monthMedium // "May"
let dateHour = date.hour12 // "1"
let dateMinute = date.minute0x // "18"
let dateAmPm = date.amPM // "PM"Stack Overflow用户

NSDateFormatter具有monthSymbols、shortMonthSymbols和veryShortSymbols属性。
所以试试这个：
let dateFormatter: NSDateFormatter = NSDateFormatter()
let months = dateFormatter.shortMonthSymbols
let monthSymbol = months[month-1] as! String // month - from your date components
println(monthSymbol)Stack Overflow用户

I am adding three types. Have a look.
//Todays Date
let todayDate = NSDate()
let calendar = NSCalendar(identifier: NSCalendarIdentifierGregorian)!
let components = calendar.components(.CalendarUnitYear | .CalendarUnitMonth | .CalendarUnitDay, fromDate: todayDate)
var (year, month, date) = (components.year, components.month, components.day)
println("YEAR: \(year) MONTH: \(month) DATE: \(date)")
//Making a X mas Yr
let morningOfChristmasComponents = NSDateComponents()
morningOfChristmasComponents.year = 2014
morningOfChristmasComponents.month = 12
morningOfChristmasComponents.day = 25
morningOfChristmasComponents.hour = 7
morningOfChristmasComponents.minute = 0
morningOfChristmasComponents.second = 0
let morningOfChristmas = NSCalendar.currentCalendar().dateFromComponents(morningOfChristmasComponents)!
let formatter = NSDateFormatter()
formatter.dateStyle = NSDateFormatterStyle.LongStyle
formatter.timeStyle = .MediumStyle
let dateString = formatter.stringFromDate(morningOfChristmas)
print("dateString : \(dateString)")
//Current month - complete name
let dateFormatter: NSDateFormatter = NSDateFormatter()
let months = dateFormatter.monthSymbols
let monthSymbol = months[month-1] as! String
println("monthSymbol : \(monthSymbol)")
Print Results:
YEAR: 2015 MONTH: 10 DATE: 9
dateString : December 25, 2014 at 7:00:00 AM
