My code is like Below:

 NSString *date_str = @"2015-05-27 10:19";
 NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd HH:mm"];
 NSDate *date = [dateFormat dateFromString:date_str];

Answer 1

Just convert your date to GMT time like this:-

NSString *date_str = @"2015-05-27 10:19";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
[dateFormat setTimeZone:gmt];
[dateFormat setDateFormat:@"yyyy-MM-dd HH:mm"];
NSDate *date = [dateFormat dateFromString:date_str];

And the output is :-

date == 2015-05-27 10:19:00 +0000

And to get the date without +0000 , you can store it in NSString directly:-

 NSString *s = [dateFormat stringFromDate:date];

Output :-

2015-05-27 10:19

You are facing the timezone issue with conversion, because server time and local timezone may have difference. So handle this you need to set the timezone to your dateformatter like

[dateFormater setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
