问题 I got a serial number form Java Date which convert into long-integer such as "1352101337000". The problem I met is how to analyze this long-integer number back to NSDate or NSString so that I can clear to know what time the serial number is displaying. Do anybody have solution for this case? 回答1: Use this, NSTimeInterval timeInMiliseconds = [[NSDate date] timeIntervalSince1970]; To change it back, NSDate* date = [NSDate dateWithTimeIntervalSince1970:timeInMiliseconds]; As per apple

NSDate countdown from NOW to NSDate

由 流过昼夜 提交于 2019-12-08 09:08:52
How can I show a countdown in HH:mm:ss format from NOW to a desired NSDate that will happen in the future? You have to use a timer for ticking the date. Store a future date, and keep on substracting future date - [nsdate today]... Calculate the time in seconds and calculate it into Hours, minutes, seconds... //Make two properties NSDate *nowDate, *futureDate futureDate=...; nowDate=[NSDate date]; long elapsedSeconds=[nowDate timeIntervalSinceDate:futureDate]; NSLog(@"Elaped seconds:%ld seconds",elapsedSeconds); NSInteger seconds = elapsedSeconds % 60; NSInteger minutes = (elapsedSeconds / 60)

Swift displaying the time or date based on timestamp

由 喜欢而已 提交于 2019-12-08 07:58:17
问题 I have an API that returns data including a timestamp for that record. In swift I have the timestamp element loaded and converted into a double and can then convert that into time.

String)! let date = NSDate(timeIntervalSince1970: unixTimeString) // This is on EST time and has not yet been localised. var
