I tried to use the NSDateFormatter to format a date that selected from a UIDatepicker. But the formatted result giving a nil.
-(NSString *)formatDateWithString:(NSString *)date{
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = #"yyyy-MMM-dd HH:mm:ss";
NSDate *formattedDate = [dateFormatter dateFromString:date];
return [dateFormatter stringFromDate:formattedDate];
}
date input is 2016-04-22 16:30:36 +0000(after selected from UIDatePicker). How may I fix this?
As mentioned in the comment you can get the NSDate directly from the UIDatePicker and pass that date directly in the formatter
NSDateFormatter * formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy-MMM-dd HH:mm:ss"];
NSString *dateString = [formatter stringFromDate:datePicker.date];//pass the date you get from UIDatePicker
If you want to convert the same way you have mentioned in the question you can try like this:
-(NSString *)formatDateWithString:(NSString *)date{
NSDateFormatter * formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy-MM-dd HH:mm:ss z"];
NSDate * convrtedDate = [formatter dateFromString:date];
[formatter setDateFormat:#"yyyy-MMM-dd HH:mm:ss"];
NSString *dateString = [formatter stringFromDate:convrtedDate];
return dateString;
}

I want to display the date in the format "28 Mar 2016 / 16:54pm" from the string "2017-05-05T08:27:31.337Z". How can I do this? Is there any buildin method for iOS? Thanks.
use NSDateFormatter for your concept
for e.g
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyyy-MM-dd'T'HH:mm:ss.SSSZ"];
NSDate *msgDate = [dateFormatter dateFromString:#"2017-05-05T08:27:31.337Z"];
[dateFormatter setDateFormat:#"dd MMM yyyy / HH:mma"];
NSString *final = [dateFormatter stringFromDate:msgDate];
update
add setAMSymbol and setPMSymbol in your dateFormatter.
[dateFormatter setAMSymbol:#"am"];
[dateFormatter setPMSymbol:#"pm"];
Full Answer
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyyy-MM-dd'T'HH:mm:ss.SSSZ"];
NSDate *msgDate = [dateFormatter dateFromString:#"2017-05-05T08:27:31.337Z"];
[dateFormatter setDateFormat:#"dd MMM yyyy / HH:mma"];
[dateFormatter setAMSymbol:#"am"];
[dateFormatter setPMSymbol:#"pm"];
NSString *final = [dateFormatter stringFromDate:msgDate];
See Instruction or introduction with every line
NSString *str = #"your date here..."; /// here this is your date with format yyyyy-MM-dd'T'HH:mm:ss.SSSZ
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; // here we create NSDateFormatter object for change the Format of date..
[dateFormatter setDateFormat:#"yyyyy-MM-dd'T'HH:mm:ss.SSSZ"]; //// here set format of date which is in your output date (means above str with format)
NSDate *date = [dateFormatter dateFromString: str]; // here you can fetch date from string with define format
dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd MMM yyyy / HH:mma"];// here set format which you want...
NSString *convertedString = [dateFormatter stringFromDate:date]; //here convert date in NSString
NSLog(#"Converted String : %#",convertedString);
I want to convert my input string to particular NSDate format,
Here is the code I have tried.
NSString * result;
NSDate * resultDate;
NSDate *date = [dateFormat dateFromString:maxUpcomingDateString];
NSDateFormatter *dateFormat1 = [[NSDateFormatter alloc] init];
dateFormat1.locale=[[NSLocale alloc] initWithLocaleIdentifier:#"en_US"];
[dateFormat1 setDateFormat:#"yyyy/MMM/dd"];
NSLog(#"maxUpcomingDateString %#",maxUpcomingDateString)
NSDate *d=[dateFormat1 dateFromString:maxUpcomingDateString];
result = [dateFormat1 stringFromDate:date];
resultDate=[dateFormat1 dateFromString:result];
NSLog(#"max1 date upcoming %#",result);
NSLog(#"max2 date upcoming %#", resultDate);
Output of my log shows:
maxUpcomingDateString 10 January 2017
max1 date upcoming 2017/Jan/10
max2 date upcoming (null)
I want the output date in the form of 2017/Jan/10. When I try to log the string it shows me the correct output but when I convert it back to NSDate it shows null.
nsstring to nsdate
NSString *dateString = #"01-02-2010";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// this is imporant - we set our input date format to match our input string
// if format doesn't match you'll get nil from your string, so be careful
[dateFormatter setDateFormat:#"dd-MM-yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
nsdate to nsstring
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd-MM-yyyy"];
NSString *stringDate = [dateFormatter stringFromDate:[NSDate date]];
NSLog(#"%#", stringDate);
add this code on dateFormat
[dateFormat setDateFormat:#"dd MMM yyyy"];
It will solve the problem.
Add this code after allocating the dateFormat object.
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd MMM yyyy"];
I have a NSString like #"2014-11-27T10:54:08.185Z"
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy'-'MM'-'dd'T'hh':'mm':'ss'.'SSS'Z'"];
NSDate * date = [dateFormatter dateFromString:self.creationTime];
I tried a lot of different formatter strings, but the date is always nil.
Or is there another problem here?
The hour in your date string format seems to be in the 24h format.
So you need to use HH instead of hh in your dateFormat.
More info
Try
NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:#"yyyy'-'MM'-'dd'T'hh':'mm':'ss'.'SSS'Z'"];
NSDate *date = [NSDate dateWithTimeIntervalSince1970:self.creationTime];
self.dateLabel.text = [formatter stringFromDate:date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd'T'HH:mm:ssZ"];
NSDate *date = [dateFormatter dateFromString:#"2013-02-01T06:25:47Z"];
NSTimeZone *pdt = [NSTimeZone timeZoneWithAbbreviation:#"PDT"];
[dateFormatter setTimeZone:pdt];
[dateFormatter setDateFormat:#"HH:mm:ss zzz"];
[dateFormatter setDateFormat:#"K:mm a, z"];
NSString * updated String = [dateFormatter stringFromDate:date];
Please try this...:)
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];
}
So i am parsing an xml file and display on screen the dates that i parse.
The dates are like : Thu , 31 May 2012 20:43:54 GMT.
How can i convert the date to this format : dd/mm/yy ?
i dont need the time.
Well it crashes.
I tried :
NSString *date = [[stories objectAtIndex: storyIndex] objectForKey: #"date"];
//changing dates format
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: #"yyyy-MM-dd HH:mm:ss Z"];
NSDate *myDate = [dateFormatter dateFromString:date];
NSString *dateText = [[NSString alloc] initWithString:[dateFormatter stringFromDate:myDate]];
Any ideas?
You can use NSDateFormatter
For example:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: #"yyyy-MM-dd HH:mm:ss Z"];
NSDate *myDate = [dateFormatter dateFromString:yourString];
See http://unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns for dateformat patterns
The idea is to use NSDateFormatter to get a date from your input time string, then use a new dateformatter to get whatever new time string you want from the date.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEE, d MMM YYYY HH:mm:ss Z"];
NSDate *date = [dateFormatter dateFromString:theDateString];
[dateFormatter release];
NSDateFormatter *dateFormatter2 = [[NSDateFormatter alloc] init];
[dateFormatter2 setDateFormat:#"dd/mm/yyyy"];
NSString *newDateString = [dateFormatter2 stringFromDate:date];
[dateFormatter2 release];
Alternatively for the second part You can use NSDateComponents.
after:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEE, d MMM YYYY HH:mm:ss Z"];
NSDate *date = [dateFormatter dateFromString:theDateString];
[dateFormatter release];
//Get NSComponents from date object..
[NSString stringWithFormat:#"%#/%#/%#",dateComponent.date,dateComponent.month,dateComponent.year];
