I have string like #"2011-03-29 15:22:16"
and I use dateformatter to get NSdate obj.
Below is my code:
NSString *dateStr = #"2011-03-29 15:22:16";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
[dateFormatter setDateStyle:NSDateFormatterLongStyle];
NSLocale *usLocale = [[NSLocale alloc] initWithLocaleIdentifier:#"en_US"];
[dateFormatter setLocale:usLocale];
NSDate *date = [dateFormatter dateFromString:dateStr];
However, date is always NULL.
I tried several time&date style, and failed either.
So can this kind of string be formatted into the NSDate object?
thanks in advance!
I presume the format is incorrect. Try setting it manually.
NSString *dateStr = #"2011-03-29 15:22:16";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:dateStr];
Maybe you can try following.
mDateFormatter = [[NSDateFormatter alloc] init];
// 2010-11-11 17:26:59
[mDateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];

In my app, i am taking date and time in to string " 2013-06-11 10:15:00 +0000 " like this, but how can i convert this string into date format. I tried like below code but i am getting error in converting.
NSString *string=#"03-05-2014";
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:#"dd-MM-yyyy"];
NSDate *dateFromString = [dateFormatter dateFromString:string];
Would you please help me in this problem?
Try to do this:
NSDateFormatter* f = [[[NSDateFormatter alloc] init] autorelease];
[f setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
NSDate *dateFromString = [f dateFromString:string];
You have to set the same date format in which the (string or date)contains, otherwise the date is returned by NSDateFormatter will be nil.
You can Use NSCalender Like this.....
NSCalendar *currentCalendar = [NSCalendar currentCalendar];
Refer This Link : Here
NSString *urDateString=#"2013-06-11 10:15:00 +0000";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSString *strDate = [urDateString stringByReplacingOccurrencesOfString:#"+0000" withString:#""];
NSDate *dateString = [dateFormatter dateFromString:strDate];
[dateFormatter setDateFormat:#"MM-DD-yyyy"];
NSString *formattedDateString = [dateFormatter stringFromDate:dateString];
NSLog(#"%#",formattedDateString);
I have an NSDateformatter that is not working correctly. I got my date as a string like this.
2013-02-20 00:00:00
And I need to return it as an NSDate like this
2013-02-20
What I've got at the moment is this.
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
[dateFormat setDateFormat:#"yyyy-MM-dd"];
[dateFormat dateFromString:dateString]
But this is not working.
Any help ?
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
NSDate* date=[dateFormat dateFromString: dateString];
[dateFormat setDateFormat:#"yyyy-MM-dd"];
NSLog(#"%#",[dateFormat stringFromDate: date]);
This will work
try it
if you have more than on date to parse, it could be worthy to create one input and one output date formatter
static NSDateFormatter *inputDateFormatter;
static NSDateFormatter *outputDateFormatter;
if (!inputDateFormatter) {
inputDateFormatter= [[NSDateFormatter alloc] init];
[inputDateFormatter setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
outputDateFormatter = [[NSDateFormatter alloc] init];
[outputDateFormatter setDateFormat:#"yyyy-MM-dd"];
}
NSDate *date = [inputDateFormatter dateFromString:#"2013-02-20 00:00:00"];
NSString *string = [outputDateFormatter stringFromDate:date];
NSLog(#"%#", string);
result
2013-02-20
as NSDateFormatter are expensive to create, you should either store them in a singleton or declare them static to create them once for that method.
And I need to return it as an NSDate like this
A date has no format, it is just a point in time. you will have to creta a string with the desired format where needed.
I have struggling with to convert nsstring to nsdate format. I have a date in nsstring format like (2011-08-25 18:30:00 +0000), but i want to change it in nsdate format (08/26/2011). How to change it? Can any one help me please? Thanks in advance... I have spend one day to solve this but i cant find out the solution.. Please help me friends....
This is my code,
NSString *dateString = #"2011-08-25 18:30:00 +0000";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MM/dd/yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
NSLog(#"Converted date is %#",dateFromString);
Output is,
Converted date is (null)
Yuva.M
NSString *dateWithInitialFormat = #"2011-08-25 18:30:00 +0000";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss Z"];
NSDate *date = [dateFormatter dateFromString:dateWithInitialFormat];
[dateFormatter setDateFormat:#"MM/dd/yyyy"];
NSString *dateWithNewFormat = [dateFormatter stringFromDate:date];
NSLog(#"dateWithNewFormat: %#", dateWithNewFormat);
From NSLog: dateWithNewFormat: 08/25/2011
See Date Format Patterns
You need to use an NSDateFormatter and set the date format to match how you're storing it, like the below.
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
NSDate *myDate = [df dateFromString: myDateString];
NSDateFormatter* df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"MMMM dd, yyyy"];
NSDate* d = [df dateFromString:#"January 06, 1992"];
NSLog(#"%#", d);
NSDate *dispalyDate = d;
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd MMM"];
NSString *str = [dateFormat stringFromDate:dispalyDate];
NSLog(#"%#", str);
For my iPhone app I got to convert NSDate object to string, and then convert the string back to NSDate object.. Can someone help me out? thank you!
Use to convert from NSDate to NSString
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy-MM-dd hh:mm:ss a"];
NSString *stringFromDate = [formatter stringFromDate:myNSDateInstance];
Use to convert from NSString to NSDate.
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"yyyy-MM-dd hh:mm:ss a"];
NSDate *myDate = [df dateFromString: stringFromDate];
You need to check out NSDateFormatter this does exactly this, both directions.
convert NSDate to NSString
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy"];
//Optionally for time zone converstions
[formatter setTimeZone:[NSTimeZone timeZoneWithName:#"..."]];
NSString *stringFromDate = [formatter stringFromDate:myNSDateInstance];
Convert 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];
// voila!
dateFromString = [dateFormatter dateFromString:dateString];
[dateFormatter release];
I am trying to make a date format in such a manner hours.minutes day/month/year
I have uses this code :
NSDateFormatter *formatter =[[NSDateFormatter alloc] init];
NSDate *dateAndtime = [NSDate date];
[formatter setTimeStyle:NSDateFormatterShortStyle];
[formatter setDateStyle:NSDateFormatterShortStyle];
//[formatter setTimeStyle:NSDateFormatterShortStyle];
NSString* dateforBD=[[NSString alloc]init];
dateforBD =[formatter stringFromDate:dateAndtime];
But this code not give me my format.
Also i have tried this code:
NSLocale *locale = [NSLocale currentLocale];
NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
NSString *dateFormat = [NSDateFormatter dateFormatFromTemplate:#"E MMM d yyyy"
options:0 locale:locale];
[formatter setDateFormat:dateFormat];
[formatter setLocale:locale];
It's also give me different format. How can i achieve the required format means 13.10 21/4/2011
All the formats return in month before date. May i have used wrong way for this ?
Thanks in advance.
NSDate *today = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"MM/dd/yyyy hh:mma"];
NSString *dateString = [dateFormat stringFromDate:today];
NSLog(#"date: %#", dateString);
[dateFormat release];

Hope it helps.
for date before month use -
[dateFormat setDateFormat:#"dd/MM/yyyy hh:mm"];
As specified in Apple's NSDateFormatter reference, the NSDateFormatter uses Unicode Date Format Patterns.
According to the unicode patterns, you would need the following pattern to achieve "13.10 21/4/2011":
hh:mm dd/MM/yyyy
So you would use this code:
NSDate *dateAndtime = [NSDate date];
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setDateFormat:#"hh:mm dd/MM/yyyy"];
NSString *newlyFormattedDateString = [dateFormatter stringFromDate:dateAndtime];
