Question

I am trying this since last two hours and finaly left it out for you guys 😛

I need to convert this String Mon, 14 May 2012, 12:00:55 +0200
into Date dd/mm/yyyy hh:ss format..

Any kind of help towards the goal will be really appreciated.

What I have tried

I have tried using NSDateFormatter but I am unable to figure out the exact format of the above date.
This [dateFormatter setDateFormat:@"EEEddMM,yyyy HH:mm:ss"]; is how I have tried and many other formats too

Eg:

 NSString *finalDate = @"Tue, 29 May 2012, 14:24:56 +0200";
 NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
 [dateFormatter setDateFormat:@"EEEddMM,yyyy HH:mm:ss"];
  NSDate *date = [dateFormatter dateFromString:finalDate];

Here the date alwasys comes as nil

Answer 1

The most important part of date formatting is often forgotten, tell the NSDateFormatter the input language:

NSDateFormatter *dateFormatter = [NSDateFormatter new];
[dateFormatter  setDateFormat:@"EEE, dd MMMM yyyy, HH:mm:ss Z"];
dateFormatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"EN"];
NSDate *date = [dateFormatter dateFromString:@"Mon, 14 May 2012, 12:00:55 +0200"];
NSLog(@"date: %@", date);

I’ve checked the output: date: 2012-05-14 10:00:55 +0000

Be aware that the HH in the date formatter is for 24hr.

Now I would suggest not to use a fixed output scheme, but use one of the NSDateFormatterStyle:

[dateFormatter setDateStyle:NSDateFormatterShortStyle];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];

NSString *dateString = [dateFormatter stringFromDate:date];

NSLog(@"date: %@", dateString);

Which in american english will output: 5/14/12 12:00 PM

This code is valid for ARC if you are not using ARC add autorelease to the NSLocale and release the NSDateFormatter after you are done with it.
