NSDateFormatter *df1 = [[NSDateFormatter alloc] init];
[df1 setDateFormat:#"EE, dd MMM YYYY HH:mm:ss zzz"];
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"yyyy-MM-dd HH:mm:ss ZZZ"];
NSString *startDateStr2 = [df1 stringFromDate:[NSDate date]];
NSLog(#"currentDate: %#", startDateStr2);
but i am getting output : Sat, 05 Jan 2013 07:26:31 GMT+05:30
Use below method which is used to change the format of the NSDate..
-(NSString *)changeDateFormat:(NSString*)stringDate dateFormat:(NSString*)dateFormat getwithFormat:(NSString *)getwithFormat{
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:dateFormat];
NSDate *date = [dateFormatter dateFromString:stringDate];
dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:getwithFormat];
NSString *convertedString = [dateFormatter stringFromDate:date];
NSLog(#"Converted String : %#",convertedString);
return convertedString;
}
Call above method with its 3 parameters..
1. stringDate : Pass your date which in string type.
2. dateFormat : set format which is used in your passed string date. For example, if your string date is "14-03-2013 11:22 am" then set the format to #"dd-MM-yyyy hh:mm a".
3. getwithFormat : Set format which you want, as if you want date 14/03/2013 then just set format #"dd/MM/yyyy".
How to call this see below example with method:
NSString *strSDate = [self changeDateFormat:#"14-03-2013 11:22 am" dateFormat:#"dd-MM-yyyy hh:mm a" getwithFormat:#"dd/MM/yyyy"];
NSLog(#"\n\n Now Date => %#",strSDate);
Output is : Now Date => 14/03/2013
hope its helpful to you...

I wish to change the date format from "2013-01-21 11:55:00" to "Jan 21, 2013 5:30 AM".
I tried the below code. But it gives a constant date.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
[dateFormatter setTimeStyle:NSDateFormatterMediumStyle];
NSDate *myDate = [NSDate dateWithTimeIntervalSinceReferenceDate:162000];
NSLog(#"%#",[dateFormatter stringFromDate:myDate]);
The above code gives constant output : Jan 3, 2001 2:30:00 AM
But in my case, date is dynamic.
NSString *firstDate = #"2013-01-21 11:55:00";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy'-'MM'-'dd HH':'mm':'ss"];
NSDate *date = [dateFormatter dateFromString:firstDate];
[dateFormatter setDateFormat:#"MMM d, yyyy h:mm a"];
NSLog(#"Expected Result___ %#",[dateFormatter stringFromDate:date]);
Try this
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MMM d, yyyy h:mm a"];
NSDate *myDate = [NSDate dateWithTimeIntervalSinceReferenceDate:162000];
NSLog(#"%#",[dateFormatter stringFromDate:myDate];
Try [NSDate date] instead [NSDate dateWithTimeIntervalSinceReferenceDate:162000].
well you get constant output since you give constant input as 162000 !!!
First get the date from the string using its format then use the new format to get string from the obtained date
use this to output format as
#"MMM d, yyyy h:mm a"
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:#"MMM d, yyyy h:mm a"];
NSLog(#"%#",[dateFormatter stringFromDate:[NSDate date]]);

NSString to NSDate
I have a date in format Mon Jan 14 14:00:00 CET 2013 I try to convert it to NSDate:
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"EEE MMM dd HH:mm:ss zzz y"];
NSString *dateString = #"Mon Jan 14 14:00:00 CET 2013"
NSDate *date = [df dateFromString:dateString];
but it doesn't work and my date is nil
Input data is in en-GB locale, my device's locale is nb-NO
Any suggestions?
You're missing day in your format:
[df setDateFormat:#"EEE MMM dd HH:mm:ss zzz y"];
If it was not a typo, then next thing is to set proper locale so formatter will recognise CET timezone, for example en-GB will fix that:
NSDateFormatter *df = [[NSDateFormatter alloc] init];
// that will fix the problem with not recognized CET timezone
[df setLocale:[[NSLocale alloc] initWithLocaleIdentifier:#"en-GB"]];
[df setDateFormat:#"EEE MMM dd HH:mm:ss zzz y"];
NSString *dateString = #"Mon Jan 14 14:00:00 CET 2013"
NSDate *date = [df dateFromString:dateString];
Try to use this function
- (NSDate*) dateFromString:(NSString*)aStr
{
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:#"en_US_POSIX"] autorelease]];
//[dateFormatter setDateFormat:#"YYYY-MM-dd HH:mm:ss a"];
[dateFormatter setDateFormat:#"MM/dd/yyyy HH:mm:ss a"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSLog(#"%#", aStr);
NSDate *aDate = [dateFormatter dateFromString:aStr];
[dateFormatter release];
return aDate;
}
I hope this will helps u.
I think your Time Zone is wrong. Just use this code , it will work Perfectly :
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"EEE MMM dd HH:mm:ss zzz y"];
NSString *dateString = #"Mon Jan 14 14:00:00 EDT 2013";
NSDate *date = [df dateFromString:dateString];
NSLog(#"date :: %#",date);
It will log Output as :
date :: 2013-01-14 18:00:00 +0000
EDIT :
I found Something for you : NSDateFormatter doesn't parse some timezones
You can solve this by using en_GB Locale , as stated : "These abbreviations do still work with the en_GB locale" in Working with Date and Time in Cocoa .
CET is not recognised
Try this :-
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"EEE MMM dd HH:mm:ss yyyy"];
NSString *dateString = #"Mon Jan 14 14:00:00 2013";
NSDate *date = [df dateFromString:dateString];
NSLog(#"%#",date);
Hope it helps you
Simply "CET" is not a recognized time zone by NSDateFormatter.
Also the date/tine is over specified, best to not try include the day or week (Mon).
Here is an example that demonstrates working code with a recognized timezone:
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"EEE MMM dd HH:mm:ss zzz yyyy"];
NSString *dateString = #"Mon Jan 14 14:00:00 EST 2013";
NSDate *date = [df dateFromString:dateString];
NSLog(#"date: %#", date);
NSLog output
date: 2013-01-14 19:00:00 +0000
NSLog(#"abbreviationDictionary: %#", [NSTimeZone abbreviationDictionary]);
does show
CET = "Europe/Paris";
so this looks like an Apple bug in NSDateFormatter.
Report the bug at: Apple Bug Reporter
You can use:
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
If you still want to custom your date format try this one:
yyyy-MM-dd HH:mm:ss ZZZ
Because can't invent your own formatted string syntax and expect it to work; you need to actually use a documented format as the documentation points it out : Formatters in OS X v10.8 and iOS 6.0 use version tr35-25.

What is wrong with this code?
NSString *strTest = #"Sun Apr 12 23:29:24 +0000 2009";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MM/dd/yy"];
NSDate *createdAtFormatted = [dateFormatter dateFromString:strTest];
self.createdAt.text = [dateFormatter stringFromDate:createdAtFormatted];
self.createdAt is a UILabel and it stays empty. Why?
When trying to use dateWithNaturalLanguageString, I get:
Your date formatter date format does not match the date format from the strTest string.
NSString *strTest = #"Sun Apr 12 23:29:24 +0000 2009";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
NSLocale *loc = [[NSLocale alloc] initWithLocaleIdentifier:#"en_US"]; // so the formatter recognizes english names for months and days
[dateFormatter setLocale:loc];
[loc release]; // remove if using ARC
[dateFormatter setDateFormat:#"EEE MMM d HH:mm:ss ZZZZ yyyy"];
NSDate *createdAtFormatted = [dateFormatter dateFromString:strTest];
NSLog(#"got %#", createdAtFormatted);
The formatter specifiers can be found here.
You are giving MM/dd/yy pattern to dateFormatter but your date string is not fit for that thus dateFormatter returning a nil date.
I have the date that is in format 2010-11-17.This is of the form NSString.
I want to convert this NSString date into format 17 Nov 2010 and display in a label
This date is just not the current date but may even be the older dates.
So I cant use the [NSDate date] instance to get the date.
I tried using NSDateFormatter with the method dateFromString.
But it gives me a null value.
Here is the code snippet
NSString *dates = #”2010-11-16”;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd MMM yyyy"];
NSDate *dates1 = [dateFormatter dateFromString:dates];
NSString *dates2 = [dateFormatter stringForObjectValue:dates1];
NSLog(#"dates : %#",dates);
NSLog(#"Dates 2 : %#",dates2);
[dateLabel setText:dates2];
NSLog(#"Formatted Date is : %#",dateLabel.text);
What should be done?
Please Help and suggest.
Thanks.
Try this
NSDateFormatter *formater = [[NSDateFormatter alloc] init];
[formater setDateFormat:#"yyyy-MM-dd"];
NSDate *date2 = [formater dateFromString:#"2010-11-17"];
[formater setDateFormat:#"d MMM yyyy"];
NSString *result = [formater stringFromDate:date2];
NSLog(#"RESULT %#",result);
I got the result.Correct me if this approach is wrong.
Here are some formats for who desire to know!!
12:16:45 PM on January 01, 2000 --> hh:mm:ss a 'on' MMMM dd, yyyy
Wednesday, Sep 12, 2018 --> EEEE, MMM d, yyyy--
09/12/2018 --> MM/dd/yyyy--
09-12-2018 14:11 --> MM-dd-yyyy HH:mm--
Sep 12, 2:11 PM --> MMM d, h:mm a--
September 2018 --> MMMM yyyy--
Sep 12, 2018 --> MMM d, yyyy
Wed, 12 Sep 2018 14:11:54 +0000 --> E, d MMM yyyy HH:mm:ss Z
2018-09-12T14:11:54+0000 --> yyyy-MM-dd'T'HH:mm:ssZ
12.09.18 --> dd.MM.yy
10:41:02.112 --> HH:mm:ss.SSS
12:16:45 PM --> hh:mm:ss a
AM or PM --> a
NSDateFormatter uses date format patterns from UNICODE.
So for your 17 Nov 2010 date you need something like this:
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"d MMM yyyy"];
NSString *result = [formatter stringForObjectValue:date];
Where date variable contains the date you'd like to format.
UPDATE: Try changing your code to this:
NSString *dates = #”2010-11-16”;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *dates1 = [dateFormatter dateFromString:dates];
[dateFormatter setDateFormat:#"dd MMM yyyy"];
NSString *dates2 = [dateFormatter stringForObjectValue:dates1];
NSLog(#"dates : %#",dates);
NSLog(#"Dates 2 : %#",dates2);
[dateLabel setText:dates2];
NSLog(#"Formatted Date is : %#",dateLabel.text);
I want to convert this ,
NSString *result1=#"Mon, 28 Sep 2009 06:35:42 PDT";
to nsdate using NSDateFormatter in iphone....
Can anyone help me?
Thanks in advance.....
I believe you want this:
NSString* dateString = #"Mon, 28 Sep 2009 06:35:42 PDT";
NSDateFormatter* newFormatter = [[[NSDateFormatter alloc] init] autorelease];
// Use this format to parse the string
[newFormatter setDateFormat:#"EEE, dd MMM yyyy hh:mm:ss zzz"];
NSDate* aDate = [newFormatter dateFromString:dateString];
// Now change the format to that desired for printing
[newFormatter setDateFormat:#"MMM dd,yyyy HH:mm:ss aaa"];
NSLog(#"%#", [newFormatter stringFromDate:aDate]);
// Result:
// 2009-09-29 23:50:09.440 test[15396:903] Sep 28,2009 06:35:42 AM
You can find these codes here (as referenced in the NSDateFormatter documentation): http://unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns
That's what I do in my program:
NSString *dateString = #"Mon, 28 Sep 2009 06:35:42 PDT";
NSDateFormatter *newFormatter = [[NSDateFormatter alloc] init];
[newFormatter setDateStyle:NSDateFormatterMediumStyle];
[newFormatter setTimeStyle:NSDateFormatterMediumStyle];
I'm using medium style, but there are more styles, you probably should use kCFDateFormatterLongStyle or kCFDateFormatterFullStyle, and then:
NSDate *aDate = [newFormatter dateFromString: dateString];
[newFormatter release];
Hope this helps
