ios - 在 iOS 中将日期转换为时间戳

Question

如何将任何给定日期转换为毫秒？例如，2014-01-23 到时间戳的转换。

NSDate *date = [dateFormatter dateFromString:@"2014-01-23"];
NSLog(@"date=%@",date);
NSTimeInterval interval  = [date timeIntervalSince1970];
NSLog(@"interval=%f",interval);
NSDate *methodStart = [NSDate dateWithTimeIntervalSince1970:interval];
[dateFormatter setDateFormat:@"yyyy/mm/dd "];
NSLog(@"result: %@", [dateFormatter stringFromDate:methodStart]);

输出结果:1970/30/01

将当前日期/时间转换为时间戳:

// current date and time
let someDate = Date()

// time interval since 1970
let myTimeStamp = someDate.timeIntervalSince1970
