Comment obtenir l'heure (heure, minute, seconde) dans Swift 3 à l'aide de NSDate?

Comment déterminer les heures, les minutes et les secondes de la classe NSDate dans Swift 3?

Dans Swift 2:

let date = NSDate()
let calendar = NSCalendar.currentCalendar()
let components = calendar.components(.Hour, fromDate: date)
let hour = components.hour

Swift 3?

Dans Swift 3. Apple supprima le préfixe 'NS' et simplifia tout. Vous trouverez ci-dessous le moyen d'obtenir l'heure, la minute et la seconde à partir du cours 'Date' (substitut NSDate)

let date = Date()
let calendar = Calendar.current

let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
print("hours = \(hour):\(minutes):\(seconds)")

Comme ceux-ci, vous pouvez obtenir l’ère, l’année, le mois, la date, etc. en passant en correspondance.

Swift 4.2 & 5

// *** Create date ***
let date = Date()

// *** create calendar object ***
var calendar = Calendar.current

// *** Get components using current Local & Timezone ***
print(calendar.dateComponents([.year, .month, .day, .hour, .minute], from: date))

// *** define calendar components to use as well Timezone to UTC ***
calendar.timeZone = TimeZone(identifier: "UTC")!

// *** Get All components from date ***
let components = calendar.dateComponents([.hour, .year, .minute], from: date)
print("All Components : \(components)")

// *** Get Individual components from date ***
let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
print("\(hour):\(minutes):\(seconds)")

Swift 3.

// *** Create date ***
let date = Date()

// *** create calendar object ***
var calendar = NSCalendar.current

// *** Get components using current Local & Timezone ***    
print(calendar.dateComponents([.year, .month, .day, .hour, .minute], from: date as Date))

// *** define calendar components to use as well Timezone to UTC ***
let unitFlags = Set<Calendar.Component>([.hour, .year, .minute])
calendar.timeZone = TimeZone(identifier: "UTC")!

// *** Get All components from date ***
let components = calendar.dateComponents(unitFlags, from: date)
print("All Components : \(components)")

// *** Get Individual components from date ***
let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
print("\(hour):\(minutes):\(seconds)")

let date = Date()       
let units: Set<Calendar.Component> = [.hour, .day, .month, .year]
let comps = Calendar.current.dateComponents(units, from: date)

Swift 4

    let calendar = Calendar.current
    let time=calendar.dateComponents([.hour,.minute,.second], from: Date())
    print("\(time.hour!):\(time.minute!):\(time.second!)")

Dans Swift 3, vous pouvez le faire,

let date = Date()
let hour = Calendar.current.component(.hour, from: date)

Mohammad Tarem
let hours = time / 3600
let minutes = (time / 60) % 60
let seconds = time % 60
return String(format: "%0.2d:%0.2d:%0.2d", hours, minutes, seconds)

==> Getting iOS device current time:-

print(" ---> ",(Calendar.current.component(.hour, from: Date())),":",
               (Calendar.current.component(.minute, from: Date())),":",
               (Calendar.current.component(.second, from: Date())))

output: ---> 10 : 11: 34

Pour mieux utile, je crée cette fonction:

func dateFormatting() -> String {
    let date = Date()
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "EEEE dd MMMM yyyy - HH:mm:ss"//"EE" to get short style
    let mydt = dateFormatter.string(from: date).capitalized

    return "\(mydt)"
}

Vous l'appelez simplement où vous voulez comme ceci:

print("Date = \(self.dateFormatting())")

c'est la sortie:

Date = Monday 15 October 2018 - 17:26:29

si vous voulez que le temps change simplement:

dateFormatter.dateFormat  = "HH:mm:ss"

et voici la sortie:

Date = 17:27:30

et c'est tout...

Cela peut être pratique pour ceux qui veulent utiliser la date du jour dans plus d’une classe.

extension String {


func  getCurrentTime() -> String {

    let date = Date()
    let calendar = Calendar.current


    let year = calendar.component(.year, from: date)
    let month = calendar.component(.month, from: date)
    let day = calendar.component(.day, from: date)
    let hour = calendar.component(.hour, from: date)
    let minutes = calendar.component(.minute, from: date)
    let seconds = calendar.component(.second, from: date)

    let realTime = "\(year)-\(month)-\(day)-\(hour)-\(minutes)-\(seconds)"

    return realTime
}

}

Usage

        var time = ""
        time = time.getCurrentTime()
        print(time)   // 1900-12-09-12-59
