Je souhaite afficher le calendrier dans ce format
à l'utilisateur. Une option consiste à utiliser "plage de chaînes" pour obtenir les composants de calendrier individuels. Le deuxième est de l'obtenir en utilisant NSCalendar qui pour moi ressemble au meilleur (est-ce?). Donc mon code est comme ci-dessous. Mais il y a deux problèmes.
Quelqu'un sait comment obtenir ce dont j'ai besoin? L'image ci-jointe est exactement ce que je veux réaliser. Là, j'utilise trois UILabel un pour "date", deuxième pour "mois, année" et troisième pour "heure".
Toute aide serait appréciée.
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)
}
Vous pouvez utiliser DateFormatter comme suit:
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"
NSDateFormatter
possède les propriétés monthSymbols
, shortMonthSymbols
et veryShortSymbols
.
Essayez donc ceci:
let dateFormatter: NSDateFormatter = NSDateFormatter()
let months = dateFormatter.shortMonthSymbols
let monthSymbol = months[month-1] as! String // month - from your date components
println(monthSymbol)
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
monthSymbol : October
Solution Swift 4.x:
//if currentMonth = 1
DateFormatter().monthSymbols[currentMonth - 1]
