I'm trying to convert this string "2011-11-23T17:59:00Z" to an NSDate.
I've seen many people have this problem, but everyone has a slightly different format. I haven't been able to hack a solution.
I've tried code such as:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
dateFormat.timeStyle = NSDateFormatterFullStyle;
[dateFormat setDateFormat: #"yyyy-MM-dd'T'HH:mm:ss'Z'"];
NSString* date = ""2011-11-23T17:59:00Z"";
NSString *dateString = [dateFormat stringFromDate: date];
dateString always comes back NULL
NSDateFormatter stringFromDate takes an NSDate object and you're passing it a string.
http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSDateFormatter_Class/Reference/Reference.html
Try NSDateFormatter dateFromString.
If you use dateFromString:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat: #"yyyy-MM-dd'T'HH:mm:ssZ"];
NSString* dateStr = #"2011-11-23T17:59:00Z";
NSDate *date = [dateFormat dateFromString:dateStr];
NSLog(#"date: %#", date);
Outputs:
2011-12-14 00:34:57.587 Craplet[440:707] date: 2011-11-23 22:59:00 +0000

NSDateFormatter dateFromString fetched older date.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *date = [dateformatter dateFromString:#"2015-05-18"];
The above function returns date as 2015-05-17 11:39:18 +0000 instead of
2015-05-18
Actually you are printing NSDate, if you are printing Date then compiler automatically convert your date to string by converting using current timezone. if you want actual converted date in NSString form then add one more line that convert NSDate to NSString like as bellowed.
NSDateFormatter * dFormatter = [[NSDateFormatter alloc] init];
[dFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *date = [dFormatter dateFromString:#"2015-05-18"];
NSLog(#"String : %#",[dFormatter stringFromDate:date]);
Output :
2015-05-18
this is working code to show the current date...might be solve your problem..you should go for this...
NSDate *Date = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSString *dateFormated = [dateFormatter stringFromDate:Date];
NSLog(#"%#", dateFormated);
I am working with NSDate i created one function which give Today date with "dd/MM/yyyy" format but NSDate always show "nil" value. I googled lot and also see lots of stackoverflow answer but all answer return NSString value not NSDate value so please guide me to get NSDate with given format.
+(NSDate*)getCurrentDate{
NSDateFormatter *DateFormatter=[[NSDateFormatter alloc] init];
[DateFormatter setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
//Date print here
NSLog(#"Utility CurrentDate: %#",[DateFormatter stringFromDate:[NSDate date]]);
NSString *dateString = [DateFormatter stringFromDate:[NSDate date]];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
NSDateFormatter *newDateFormatter = [[NSDateFormatter alloc]init];
[newDateFormatter setDateFormat:DATE_FORMAT];
//Date print here
NSLog(#"New Date: %#",[newDateFormatter stringFromDate:[NSDate date]]);
NSDate *dateFromString = [newDateFormatter dateFromString:dateString];
return dateFromString;
}
The issue is here
NSDate *dateFromString = [newDateFormatter dateFromString:dateString];
Here your dateString is 2014-12-11 03:41:31, hence it is not getting formatted. You should change either newDateFormatter or DateFormatter to convert as per your requirement.
EDIT:
Replace [DateFormatter setDateFormat:#"yyyy-MM-dd hh:mm:ss"]; with [DateFormatter setDateFormat: DATE_FORMAT];
But your return date will not be in the desired way, since you are returning an NSDate Object. You should return a formatted string.
You are completely misunderstanding what NSDate is and does. An NSDate is an absolute point in time. It has no format. It cannot have a format. It is absolutely impossible to have an NSDate in "dd/MM/yyyy" format or in any other format.
When you want to display a date to the user, you use NSDateFormatter to convert the NSDate into a string. In any format you like.
check here Convert date from string or you can use this methods to convert.
These all three functions you can use to format date values..
-(NSString*)getStringFromDate:(NSDate*)pDate withFormat:(NSString*)pDateFormat{
NSDateFormatter *dtFormatter = [[NSDateFormatter alloc] init];
[dtFormatter setDateFormat:pDateFormat];
[dtFormatter setLocale:[NSLocale systemLocale]];
return [dtFormatter stringFromDate:pDate];}
-(NSDate*)getDateFromString:(NSString*)pStrDate withFormat:(NSString*)pDateFormat{
NSDateFormatter *dtFormatter = [[NSDateFormatter alloc] init];
[dtFormatter setDateFormat:pDateFormat];
[dtFormatter setLocale:[NSLocale systemLocale]];
return [dtFormatter dateFromString:pStrDate];}
-(NSString*)dateStringFromString:(NSString *)dateToConver format:(NSString *)fromFormat toFormat:(NSString *)toFormat{
NSDate *date = [Helper getDateFromString:dateToConver withFormat:fromFormat];
return [Helper getStringFromDate:date withFormat:toFormat];}
Refer the below modified method in dd/MM/yyyy format:-
+(NSString*)getCurrentDate{
NSDateFormatter *format=[[NSDateFormatter alloc]init];
[format setDateFormat:#"yyyy-MM-dd HH:mm:ss ZZZ"];
NSString *currentDt=[format stringFromDate:[NSDate date]];
NSDate *dt=[format dateFromString:currentDt];
[format setDateFormat:#"dd/MM/yyy"];
return [format stringFromDate:dt];
}
I need to change string that is in 12 hour time format into NSDate. I am using below given code but its returning null. Can anyone help me with this??
NSString = #"04/03/2013 7pm";
NSDateFormatter *df = [[NSDateFormatter alloc]init];
[df setDateFormat:#"dd/MM/yyyy hh:mm a"];
NSDate *date = [df dateFromString:selectedDateString];
It is giving you null as your DateFormat does not match to your string.
Try this,
NSString *selectedDateString= #"04/03/2013 7pm";
NSDateFormatter *df = [[NSDateFormatter alloc]init];
[df setDateFormat:#"dd/MM/yyyy ha"];
NSDate *date = [df dateFromString:selectedDateString];
I want compare two dates. I am getting device date in yyyy-dd-mm format and getting mm-dd-yyyy from webservices. I want to change device date format and get that changed date in NSDate object. Here is my code:
NSDate *today = [[NSDate alloc] init];
NSLog(#"today : %#", today);
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MM dd yy"];
NSString *tString = [dateFormatter stringFromDate:today];
NSLog(#"tString : %#",tString);
NSDate *date = [dateFormatter dateFromString:tString];
NSLog(#"date : %#",date);
You are saying date coming from webservice is in mm-dd-yyyy format..Then convert it into NSDate like this
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MM-dd-yyyy"];
NSDate *convertedDate = [dateFormatter dateFromString:yourDateStringFromWeb];
You have device date already with you..Now you can compare two NSDate objects in many ways..See this and this..
I have made a calendar application for the iPhone in which I have a date in string format (e.g. "Tue, 25 May 2010 12:53:58 +0000").
I want to convert this to an NSDate.
What do I need to use to do that?
Take a look at the class reference for NSDateFormatter. You use it like this:
NSString *dateStr = #"Tue, 25 May 2010 12:53:58 +0000";
// Convert string to date object
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"EE, d LLLL yyyy HH:mm:ss Z"];
NSDate *date = [dateFormat dateFromString:dateStr];
[dateFormat release];
For more information on how to customize that NSDateFormatter, try this reference guide.
EDIT:
Just so you know, this is going to parse the full month name. If you want three letter month names, use LLL instead of LLLL.
-(NSString *)dateToFormatedDate:(NSString *)dateStr {
NSString *finalDate = #"2014-10-15";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *date = [dateFormatter dateFromString:dateStr];
[dateFormatter setDateFormat:#"EE, d MMM, YYYY"];
return [dateFormatter stringFromDate:date];
}
If you are storing dates in one of iOS' styles, it's far easier and less error prone to use this method:
// Define a date formatter for storage, full style for more flexibility
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterFullStyle];
[dateFormatter setTimeStyle:NSDateFormatterFullStyle];
// Use today as an example
NSDate *today = [NSDate date];
// Format to a string using predefined styles
NSString *dateString = [dateFormatter stringFromDate:today];
// Format back to a date using the same styles
NSDate *todayFromString = [dateFormatter dateFromString:dateString];
NSString *dateString=#"2017-05-25";
NSDateFormatter *dateFormatter=[NSDateFormatter alloc]init];
[dateFormatter setDateFormatter:#"MM-dd-yyyy"];
NSDate *date =[[NSDate alloc]init];
date=[datFormatter dateFromString:dateString];
