Converting timestamp string with T and Z characters to NSDate [duplicate]

问题

This question already has answers here:

Is there a simple way of converting an ISO8601 timestamp to a formatted NSDate? (8 answers)

Closed 5 years ago.

I don't know how to convert this string to NSDate.

Date is in this format "2012-10-21T07:00:00Z"

I guess the problem is that I have no clue what those T and Z mean in the string :)

NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:@"yyyy-MM-ddTHH:mm:ssZ"];
NSDate *dateStart = [formatter dateFromString:@"2012-10-21T07:00:00Z"];

// format that I want
    [formatter setDateFormat:@"yyyy-MM-dd HH:mm"];

NSLog(@"date: %@", [formatter stringFromDate:dateStart]);

all dates are in that format: 2014-09-12T03:46:25Z

That is an ISO date. The Z stands for Zulu but means UTC time.

Try:

[formatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZZZ"];

To feed your initial nsdate.
