Swift 3 ile NSDate kullanarak zaman nasıl alınır (saat, dakika, saniye)?

Question

Swift 3'teki NSDate sınıfından saat, dakika ve saniye nasıl belirlenir? Swift 2'de

:

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

Swift 3?

Answer 1

Swift 3.0 Apple, 'NS' önekini kaldırdı ve her şeyi basitleştirdi. Aşağıda saat, dakika almanın yolu ve ikinci 'Tarih' sınıfı (NSDate vekili) karşılık gelen ileterek çağ, yıl, ay, tarih vs. alabilirsiniz bunlar gibi

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)") 

değil.

Answer 2

Swift bunu yapabilirsiniz Swift 3'te 3,0

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

// *** 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 as Date) 
print("All Components : \(components)") 

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

Answer 3

,

let date = Date()

Answer 4

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

Answer 5

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) 

Answer 6

swift 4 

==> 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
