如何将 Swift 中的“2020-04-10T18:46:42+08:00”转换为“18:46”？

Question

我尝试格式化它，但找不到更好的解决方案。

Answer 1

您可以使用Calendar class component(_:from:) 方法获取小时和分钟。

let calendar = Calendar.current
calendar.component(.hour, from: date) // hour
calendar.component(.minute, from: date) // minute

Answer 2

调用函数

let getDate = "2020-04-10T18:46:42+08:00"
let x = self.dateInRequiredFormat(stringDate: getDate, requiredFormat : "HH:mm")
print("date:- \(x)")

日期格式化函数

 func dateInRequiredFormat(stringDate:String, requiredFormat:String)->String{
    let dateFormatter = DateFormatter()
    dateFormatter.calendar = Calendar(identifier: .gregorian)
    dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZZZZZ"
    let checkInDateStr = dateFormatter.date(from: stringDate)!
    dateFormatter.dateFormat = requiredFormat
    let dateInRequiredFormat = dateFormatter.string(from: checkInDateStr)
    return dateInRequiredFormat
}
