Hi i have date format in ISO8601 as example:
NSString *currentDateString = #"2016-01-12T21:21:22.737+05:30";
i want to get only date which is 2016-01-12 from this string:
i tried
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *currentDate = [dateFormatter dateFromString:currentDateString];
NSLog(#"CurrentDate:%#", currentDate);
its retuning null but i want to get date in format of yyyy-MM-dd.
Please try this code.
NSString *dateString = #"2013-04-18T08:49:58.157+0000";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];
// Always use this locale when parsing fixed format date strings
NSLocale *posix = [[NSLocale alloc] initWithLocaleIdentifier:#"en_US_POSIX"];
[formatter setLocale:posix];
NSDate *date = [formatter dateFromString:dateString];
NSLog(#"date = %#", date);
Found a solution using NSRange:
NSString *currentDateString = #"2016-01-12T21:21:22.737+05:30";
NSRange range = [currentDateString rangeOfString:#"T"];
NSString *newString = [currentDateString substringToIndex:range.location];
NSLog(#"%#",newString);

I have two user selected dates: startDate and endDate. They are NSDate instances and I have to send them as parameters as NSNumbers. How can I convert them to NSNumber with seconds?
Use below code :
NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
// set format however you want
[formatter setDateFormat:#"ddMMyyyy"];
NSDate *date = [NSDate date];
NSString *string = [formatter stringFromDate:date];
NSNumber *num1 = #([string intValue]);
NSLog(#"%#",num1);
1) First, get the date in MM/dd/yyyy format:
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"MM/dd/yyyy"];
2) get string date and remove '/' from it:
NString *string = [formatter stringFromDate:date];
NString *finalStr = [string stringByReplacingOccurrencesOfString:#"/" withString:#""];
3) Use NSNumberFormatter from converting NSString to NSNumber:
NSNumberFormatter *f = [[NSNumberFormatter alloc] init];
f.numberStyle = NSNumberFormatterDecimalStyle;
NSNumber *myNumber = [f numberFromString: finalStr];
Hope, this is what you want!
If you mean a timestamp format
NSDate *date = [NSDate date];
NSTimeInterval ti = [date timeIntervalSince1970];
How to convert NSDate into Unix timestamp in Objective C/iPhone?
Thanks,
I have a time zone formatted like this in an incoming string which I have no control over (it comes in a dictionary from server)
tzHours = NSString * #"+01:00"
But I need to convert it into a NSTimeZone so I can format a date
NSString *date = [dateDictionary safeObjectForKey:#"date"];
NSString *time = [dateDictionary safeObjectForKey:#"time"];
NSString *tzHours = [dateDictionary safeObjectForKey:#"timeZone"];
// Format the date based off the timezone
NSDateFormatter *formatter = [self _apiDateFormatterWithTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
But I am unsure how to do this.
Is there a good way to do handle this?
Many thanks
So given you have the three NSStrings: date, time and tzHours. You could do something like this:
NSString *date = #"2015-01-01";
NSString *time = #"14:00:01";
NSString *tzHours = #"+01:00";
NSString *dateString = [NSString stringWithFormat:#"%# %# %#", date, time, tzHours];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = #"yyyy-MM-dd HH:mm:ss ZZZZZ";
dateFormatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:#"en_US_POSIX"];
NSDate *dateObject = [dateFormatter dateFromString:dateString];
The dateFormat of the NSDateFormatter naturally depends on the format of date and time.
Also remember to cache the NSDateFormatter or else you will suffer performance-wise.
Hi I need to convert this string
"2013-12-05T08:58:55.9345456+02:00"
to NSDate
I am trying next format but without luck
"yyyy-MM-dd'T'HH:mm:SSSSSSSZZZZZ"
Code below.
Can you help me with right format
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
// "2013-12-05T08:58:55.9345456+02:00"
[dateFormat setDateFormat:#"yyyy-MM-dd'T'HH:mm:SSSSSSSZZZZZ"];
NSDate *date = [dateFormat dateFromString:jsonDateString];
Your format is close. You need:
yyyy-MM-dd'T'HH:mm:ss.SSSSSSSZZZZZ
And be sure to set the formatter's locale to en_US_POSIX. This should always be done when parsing fixed formatted, non-localized strings.
NSString * dateStr = #"2013-12-05T08:58:55.9345456+02:00";
NSArray *dateStrParts = [dateStr componentsSeparatedByString:#"T"];
NSString *datePart = [dateStrParts objectAtIndex:0];
NSString *timePart = [dateStrParts objectAtIndex:1];
NSString *t = [[timePart componentsSeparatedByString:#"."] objectAtIndex:0];
NSString *newDateStr = [NSString stringWithFormat:#"%# %#",datePart,t];
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
[df setDateFormat:#"yyyy-MM-dd HH:mm:ss"]; // Change here for your formated output
NSDate *date = [df dateFromString:newDateStr];
NSLog(#"%#",date);
Output
2013-12-05 08:58:55 +0000
The problem lies in the timezone where you have +02:00.
The ZZZZ only parses to +0000, hence you are getting nil.
You can do in this way:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
NSString *jsonDateString = #"2013-12-05T08:58:55.9345456+02:00";//#"2013-12-05T08:58:55.9345456+02:00"
NSRange lastColon = [jsonDateString rangeOfString:#":" options:NSBackwardsSearch];
if(lastColon.location != NSNotFound) {
jsonDateString = [jsonDateString stringByReplacingCharactersInRange:lastColon withString: #""];
}
[dateFormat setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss'.'SZ"];
NSDate *date = [dateFormat dateFromString:jsonDateString];
NSLog(#"%#",date)
EDIT:
As per rmaddy's comment, you should use SSSSS instead of single S.
I have a date string in JSON format, it looks like this:
2013-05-22T10:54:40.437
And I'm trying to convert it to NSDate.
- (NSString *)dateFromString:(NSString *)datestring{
// Convert string to date object
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy'-'MM'-'dd'T'HH':'mm':'ss"];
NSDate *date = [dateFormat dateFromString:datestring];
//date is nil here.
NSDateFormatter *newDateFormatter = [[NSDateFormatter alloc]init];
[newDateFormatter setDateFormat:#"MM/dd/yyyy"];
NSString *newString = [newDateFormatter stringFromDate:date];
NSLog(#"Date -- %#",datestring);
return newString;
}
But date is nil after dateFromString. Does anyone know what I did wrong here?
Thanks!
Use this date format:
yyyy-MM-dd'T'HH:mm:ss.SSS
Your code with little modification:
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss.SSS"];
NSDate *date = [dateFormat dateFromString:datestring];
NSDateFormatter *newDateFormatter = [[NSDateFormatter alloc]init];
[newDateFormatter setDateFormat:#"MM/dd/yyyy"];
NSString *newString = [newDateFormatter stringFromDate:date];
NSLog(#"Date: %#, formatted date: %#", date, newString);
gives me this output:
Date: 2013-05-22 08:54:40 +0000, formatted date: 05/22/2013
Edit: how "ikinci viking" pointed out in comment, escaping the dashes is unnecessary. Escaping removed from the code
Update for iOS 11+
ISO8601DateFormatter is the recommended way to parse internet date on iOS 10+.
However it has few issues preventing it from usage with the specific format from the question:
Milliseconds are supported only on iOS 11+
It does not work for dates without timezone (the case in question). Date string must contain timezone part (e.g. +00:00 or Z for "Zulu time" UTC)
If date strings contains both milliseconds and timezone (e.g. 2018-09-07T14:04:13.143Z), it can be used as follows (Swift example):
let isoDateFormatter = ISO8601DateFormatter()
isoDateFormatter.formatOptions = [.withInternetDateTime, .withFractionalSeconds]
Your date format is incorrect. It should be:
[dateFormat setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss:SSS"];
The three capital 'S' means it will take the fractional part to 3 digits. Adjust it as you will.
If your date format is "2014-02-25T13:05:10+00:00" then,
your code should be like this....
NSURL *url = [NSURL URLWithString:#"your URL"];
NSString *str = [[NSString alloc] initWithContentsOfURL:url usedEncoding:Nil error:Nil];
NSDateFormatter *dateFor = [[NSDateFormatter alloc] init];
[dateFor setDateFormat:**#"yyyy-MM-dd'T'HH:mm:ss'+'SS:SS"**];
NSDate *yourDate = [dateFor dateFromString:str];
NSLog(#"Your Date: %#",yourDate);
-(void)viewDidLoad {
self.date = [dateForRFC3339DateTimeString:#"2015-01-18T01:00:00.000Z"];
}
-(NSDate *)dateForRFC3339DateTimeString:(NSString *)rfc3339DateTimeString {
NSDateFormatter *rfc3339DateFormatter = [[NSDateFormatter alloc] init];
[rfc3339DateFormatter setDateFormat:#"yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'"];
[rfc3339DateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
// Convert the RFC 3339 date time string to a NSDate.
NSDate *result = [rfc3339DateFormatter dateFromString:rfc3339DateTimeString];
return result;
}
I am reading in a file of strings. Each string looks something like:
!AIVDO,1,1,,B,11b4N?HPs0KLrBDIStg;q?w22<06,0*5A,21/10/2011 12:01:13 PM
What I have done so far is:
NSArray *arrayFromString = [theString componentsSeparatedByString:#","];
NSString *dateString = [tempArrayFromAISString objectAtIndex:7];
// dateString = #"21/10/2011 12:01:13 PM";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"d/M/yyyy h:mm:ss a"];
NSDate *date = [dateFormat dateFromString:dateString];
This returns an NSDate of (null).
The string is set ok because when I output it with NSLog it looks good.
The date formatter is ok because if I uncomment the line commented out and set the date string myself it works.
Any ideas as to why the string from the array does not work?
Thanks in advance for any help.
Change to
[dateFormat setDateFormat:#"dd/MM/yyyy HH:mm:ss a"];
Your example contains a typo. arrayFromString≠tempArrayFromAISString
This works for me
NSString *theString = #"!AIVDO,1,1,,B,11b4N?HPs0KLrBDIStg;q?w22<06,0*5A,21/10/2011 12:01:13 PM";
NSArray *arrayFromString = [theString componentsSeparatedByString:#","];
NSString *dateString = [arrayFromString objectAtIndex:7];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"d/M/yyyy h:mm:ss a"];
NSDate *date = [dateFormat dateFromString:dateString];
NSLog(#"%#", date);
There was a newline character at the end because I was reading from a file. I fixed it with:
dateString = [dateString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
This gets rid of the end of line character.
