• Converting an ISO 8601 timestamp into an NSDate: How does one deal with the UTC time offset? 5 answers

I have a string like this

NSString *datestr = @"2013-08-06T03:51:54+00:00";

I try to set dateformat as below:

NSDateFormatter *dformat = [[NSDateFormatter alloc]init];

[dformat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];

NSDate *date = [dformat dateFromString:datestr];

But the date will be nil, so, can anyone tell me how to set the dateformat, thx!

Answer 1

Try this:

 NSDateFormatter *dformat = [[NSDateFormatter alloc]init];

[dformat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZ"];

NSDate *date = [dformat dateFromString:datestr];

Add ZZZ to the end of your formatter.

Try out this code

NSString *datestr = @"2013-08-06T03:51:54+00:00";
NSDateFormatter *dformat = [[NSDateFormatter alloc]init];

[dformat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssz"];

NSDate *date = [dformat dateFromString:datestr];

use small z where z give you - with the specific non-location format. Where that is unavailable, falls back to localized GMT format. Use one to three letters for the short format or four for the full format. In the short format, metazone names are not used unless the commonlyUsed flag is on in the locale
