Date conversion from string to NSDate in ios

I have searched over internet for a long time to get this but I can't find the solution. I have received a date string from web services as "22 May 2014", I have to convert into NSDate format for check it with current date. And I have to find out the date from web service is in future or in past time.

The actual problem is that when I convert this using

NSDate *date;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd MMMM YYYY"];
date = [dateFormatter dateFromString:dateString];

But I get an entirely Different Date, Sample Input dateString:22 June 2014 and Output I get is 2013-12-21 18:30:00+0000

Please suggest any solutions.

Thanks in advance. :)

You're using YYYY, which doesn't mean what you think it means. From the TR35-31 documentation, Y is the symbol for "year in week-of-year calendars".

You want dd MMMM yyyy instead as your format string. Mixing week-of-year-based fields and regular day/month/year fields is a recipe for odd problems.

Additionally, you may well want to set the time zone in your formatter - if you're just parsing a date, then you should consider using UTC, and make sure that all your calculations and formatting/parsing use UTC.

(I suspect the issue here is that week-of-year hasn't been set, so is assumed to be 1... and the week-year 2014 started on December 30th. Then the day-of-month is set to 22 by the dd part, and then your time zone offset of UTC+05:30 is taken into account.)
