I have datetime values coming into my app from a web service. The format is as follows:
2013-03-24T09:45:00.000-04:00
I need only the time from this value. I am using NSDateFormatter and am setting the date format as follows:
[df setDateFormat:#"HH:mm:ss"];
and when I do this I get a rather cryptic runtime error. However, I have no errors when I use the following (though it doesn't satisfy my requirement):
[df setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss.sssz"];
Can someone help?
Try this
NSString *originalDateString = #"2013-03-24T09:45:00.000-04:00";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss.sssz"];
NSDate *date = [dateFormatter dateFromString:originalDateString];
[dateFormatter setDateFormat:#"HH:mm:ss"];
NSString *newDateString = [dateFormatter stringFromDate:date];
Maybe if you use date formater to retrieve a NSDate instance and from there do you own formating.
NSSTring *dateString = "2013-03-24T09:45:00.000-04:00";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
NSDate *dateFromWebApp = [dateFormatter dateFromString:dateString];
Haven't tested tho but it should work.
Cheers

All,
I want date format in dd/MMM/yyyy format below is the code i am using.
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateStyle:#"dd/MMM/yyyy"];
NSString *dateString = [formatter stringFromDate:[NSDate date]];
But in the dateString i am getting in Oct 21,2014 which is diffrent how can i get in "21/Oct/2014" format please let me know
The issue is that you're calling setDateStyle: instead of setDateFormat:
Use this code
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd/MMM/yyyy"];
NSString *dateString = [dateFormat stringFromDate:[NSDate date]];
NSLog(#"%#", dateString);
This code outputs "22/Oct/2014"
I am getting the date in NSString format as mentioned below.
Input:datestring = 30/04/2013 04:49 PM
I am applying the format for NSDateformatter as mentioned below to convert this NSString to NSDate .
Format:dateFormat= dd/MM/yyyy hh:mm a
I still get the date conversion to Nil. Please help as I am not understanding this issue.Here is my code snippet to explain what i am doing in the utility function.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:dateFormat];
NSDate *date = [dateFormatter dateFromString:dateString];
return date;
Try This....
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd/MM/yyyy hh:mm a"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:#"UTC"]];
NSDate *date = [dateFormatter dateFromString:#"30/04/2013 04:49 PM"];
NSLog(#"%#",date);
I was using NSDateFormatter to convert a date NSString instance to a NSDate object. At a point, I realized that something isn't right, when I did a check, it seemed like NSDateFormatter was loosing a whole year when converting from a string to a NSDate.
The code looks like this:
NSString *dateString = [dictionary objectForKey:#"match_date_time"];
if (dateString) {
// dateString is "2012-10-30 04:30:00"
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setTimeZone:[NSTimeZone timeZoneWithName:#"GMT"]];
[formatter setDateFormat:#"YYYY-MM-dd HH:mm:ss"];
self.date = [formatter dateFromString:dateString];
// self.date ends up 2011-10-30 04:30:00 +0000, yes 2011 not 2012.
}
Does anyone know why does NSDateFormatter fails so miserably?
Thanks!
just write below code
[formatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
I have Date is 2012-09-25 09:33:10 +0000 , using
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSDate *d = [dateFormatter dateFromString:sDate];
// sDate = #"2012-September-21"
But i get nil , instead of a formatter date. What can be the issue ?
Since your sDate = #"2012-September-21", it does not have time (hour minutes and seconds) in your string sDate. So you should set your format like this
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
You don't include time into string. You also need to fix the locale:
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
[dateFormatter setLocale:[NSLocale localeWithLocaleIdentifier:#"en_US"]];
[dateFormatter dateFromString:#"2012-September-21"];
From your question it is not clear that what is input, but i have tested with below given input it is working
NSString *dateString = #"2012-09-25 09:33:10";
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
dateFormatter.dateFormat = #"yyyy-MM-dd HH:mm:ss";
NSDate *date = [dateFormatter dateFromString:dateString];
I try to convert my NSString to NSDate object, but NSDateFormatter returns me a strange value.
Here is code:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd HH:mm"];
NSDate *date = [dateFormat dateFromString:#"2012-08-15 00:00"];
[dateFormat release];
date value is 2012-08-14 21:00 +0000. It is 3 hours difference between NSString value and NSDate value. I think I've missed something, but I don't know what.
This is what i use:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd HH:mm:ss ZZZ"];
NSDate *date = [dateFormat dateFromString:#"2012-08-15 00:00:00 +0000"];
NSLog(#"\n\n DATE: %# \n\n\n", date);
The +0000 is timezone, so make sure you use your timezone, like +0400.
Edit:
If you can't change the string, you can use this code to do it:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd HH:mm"];
[dateFormat setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSDate *date = [dateFormat dateFromString:#"2012-08-15 00:00"];
As i knew NSDate holds Grinwich time, so if you are in Moscow time zone, everything is wright
In objective c for NSDate if you did not set the setTimeZone, NSDate will take default timezone as localTimeZone. so if you need to get the exact date which you give as NSString string format, you need to setTimeZone as UTC. Follow the sample code, I guess it will be helpful for you.
NSDateFormatter *loacalformatter=[[NSDateFormatter alloc]init];
[loacalformatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSDate *localDate =[loacalformatter dateFromString:#"2012-08-15 00:00"];
NSLog(#"localDate :%#",localDate);
NSDateFormatter *UTCformatter=[[NSDateFormatter alloc]init];
[UTCformatter setTimeZone:[NSTimeZone timeZoneWithName:#"UTC"]];
[UTCformatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSDate *UTCDate =[UTCformatter dateFromString:#"2012-08-15 00:00"];
NSLog(#"UTCDate :%#",UTCDate);
UTCDate :2012-08-15 00:00 +0000 (GMT+00:00)
As suggested in the comments, if the date you receive is UTC then you need to convert it to your local timezone. Apple recommend you always use a properly configured NSDateFormatter when displaying dates, to handle localisation issues.
Here's some example code for turning an NSDate into an NSString:
NSDate *date = // initialised elsewhere
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
dateFormat.locale = [NSLocale currentLocale];
dateFormat.timeZone = [NSTimeZone localTimeZone];
dateFormat.timeStyle = NSDateFormatterShortStyle;
dateFormat.dateStyle = NSDateFormatterShortStyle;
dateFormat.locale = [NSLocale currentLocale];
NSString *dateAsString = [dateFormat stringFromDate:date];
