how to convert Javascript Date to iOS date format

Question

I am new in iOS development. Actually I am trying to show some information which I get from a web service in a table view. I have successfully retrieved the response as JSON in my code, but in my table view there is a label to show date. But in my response the date is something like this

/Date(1391068800000)/

How can I convert this to show in my table view? I think this is Javascript date. But I'm not sure how to convert it.

Answer 1

NSDate *date = [NSDate dateWithTimeIntervalSince1970:[your timestamp doublevalue]/1000];

除以1000的原因毫秒（13位）

Answer 2

The date in your response is a timestamp. You can create a date object by:
NSDate *date = [NSDate dateWithTimeIntervalSince1970:1391068800000];

After that you can convert this date to a string in an appropriate format by using the NSDateFormatter class. For example:

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];  
[formatter setDateStyle:NSDateFormatterMediumStyle];  
NSString *dateString = [formatter stringFromDate:date];
