我有以下字符串作为12-Hr格式时间:
let timeFrom = "05:30 AM";
let timeTo = "04:35 PM";
并尝试从这些中获取日期以进行比较,如下所示:
let openTime = timeFrom.date(format: "hh:mm a")
let closeTime = timeTo.date(format: "hh:mm a")
使用此扩展程序:
extension String
{
func date(format:String) -> Date?
{
let formatter = DateFormatter()
formatter.dateFormat = format
formatter.timeZone = NSTimeZone.local
return formatter .date(from: self)
}
}
当我打印openTime和closeTime时,我的时间值不正确:
print(openTime) // 2000-01-01 00:00:00 +0000
print(closeTime) // 2000-01-01 11:00:00 +0000
为什么会这样?我认为这与时区有关,所以我访问NSDateFormatter return wrong date + Swift,但没有任何对我有用。如果有人有解决方案,请帮助我。谢谢!

我使用swift 3和Xcode 8进行检查,只需更改其工作情况,请检查
let timeFrom = "05:30 AM";
let timeTo = "04:35 PM";
let openTime = timeFrom.date(format: "hh:mm a")
let closeTime = timeTo.date(format: "hh:mm a")
print(openTime)
print(closeTime)
并在扩展名中进行更改
extension String{
func date(format:String) -> Date?
{
let formatter = DateFormatter()
formatter.timeZone = NSTimeZone(abbreviation: "GMT+0:00") as TimeZone!
formatter.dateFormat = format
//formatter.timeZone = NSTimeZone.local
return formatter .date(from: self)
}}
