swift 中的日期格式化程序
Date Formatter in swift
我想获得这种类型的甲酸盐 -> 2018 年 4 月 20 日 9:02:00 下午 UTC+5:30
对于 Firestore 时间戳。我已经尝试过这段代码,但没有像上面那样得到正确的甲酸盐。
let date = Date()
let formatter = DateFormatter()
formatter.dateFormat = "MMMM d yyyy hh:mm:ss a Z"
formatter.timeZone = NSTimeZone(name: "IST") as TimeZone?
let result = formatter.string(from: date)
print(result)
已经在使用这个格式化程序 formatter.dateFormat = "MMMM d yyyy'T'hh:mm:ss a Z"
谢谢
你可以这样使用:
let date = Date()
let formatter = DateFormatter()
formatter.dateFormat = "MMMM dd, yyyy 'at' hh:mm:ss a 'UTC'Z" //If you dont want static "UTC" you can go for ZZZZ instead of 'UTC'Z.
formatter.timeZone = TimeZone(abbreviation: "IST")
let result1 = formatter.string(from: date)
print(result1)
Note: If you do not want the UTC to be static in the string, you can also use the format "MMMM dd, yyyy 'at' hh:mm:ss a ZZZZ"

let formatter = DateFormatter()
//If you want it in your specific format you can simply add 'UTC'
formatter.dateFormat = "MMMM dd, yyyy 'at' hh:mm:ss a 'UTC'Z"
formatter.timeZone = NSTimeZone(name: "IST") as TimeZone?
let result = formatter.string(from: Date())
print(result)
Note: if you want to set the currentTimezone for your string then use the format "MMMM dd, yyyy 'at' hh:mm:ss a ZZZZ"
你得到的输出为
如果您不想在小时中使用前导零,请尝试此操作,因为小时只有一个数字。此外,您不需要将 NSTimeZone 强制转换为 TimeZone。可以直接使用TimeZone。
let date = Date()
let formatter = DateFormatter()
formatter.dateFormat = "MMMM dd, yyyy 'at' h:mm:ss a 'UTC'Z"
formatter.timeZone = TimeZone(abbreviation: "IST")
let result = formatter.string(from: date)
print(result)
