I've read the DateFormatting guide and I'm still not able to get why my date conversion is not working as per requirement. For example:
NSString *str1 = #"12/20/2013 12:39:55 PM";
NSDateFormatter *dateFo = [[NSDateFormatter alloc] init];
[dateFo setDateFormat:#"MM/dd/YYYY hh:mm:ss a"];
NSDate *serverDate1 = [NSDate date];
serverDate1 = [dateFo dateFromString:str1];
In return I'm getting date as "2013-01-05 07:09:55 +0000".
I have tried a lot why NSDate is not returning correct date.
Any help would be appreciated.
Instead of YYYY use yyyy in your dateFormat:.
NSString *str1 = #"12/20/2013 12:39:55 PM";
NSDateFormatter *dateFo = [[NSDateFormatter alloc] init];
[dateFo setDateFormat:#"MM/dd/yyyy hh:mm:ss a"];
NSDate *serverDate1 = [NSDate date];
serverDate1 = [dateFo dateFromString:str1];
NSString *dateWithInitialFormat = #"12/20/2013 12:39:55 PM";
NSDateFormatter *dateFo = [[NSDateFormatter alloc] init];
[dateFo setDateFormat:#"MM/dd/yyyy hh:mm:ss a"];
NSDate *serverDate1 = [NSDate date];
serverDate1 = [dateFo dateFromString:dateWithInitialFormat];
This will get you your solution

I have application in which i am using NSDate and saving it in NSString but NSString store 000.000 like this here is the code which i am using
NSDate* date = [NSDate date];
NSDateFormatter* formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy-MM-dd HH:MM:SS"];
NSString* str = [formatter stringFromDate:date];
NSString*content_AddedTime=str;
NSString *post =[[NSString alloc] init];
post = [NSString stringWithFormat:#"userId=%#&catalogID=%#&content_AddedTime=%#&organizationCode=%#",userId,catalogID,content_AddedTime,organizationCode];
Try this:
[formatter setDateFormat:#"yyyy/MM/dd HH-mm-ss"];
or you can use:
[formatter setDateFormat:#"EEE, dd MMM yyyy HH:mm:ss ZZZ"];
Hope it will help!
Try to Log the NSString.There is no issue with your code.
NSDate* date = [NSDate date];
NSDateFormatter* formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy-MM-dd HH:MM:SS"];
NSString* str = [formatter stringFromDate:date];
NSString*content_AddedTime=str;
NSLog(#"%#",str);
NSLog(#"%#",content_AddedTime);
OutPut:
2013-07-30 12:07:67
2013-07-30 12:07:67
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:#"MMMM/dd/yyyy"];//set ur format
NSDate *date = [NSDate date];
NSString *str= [dateFormatter stringFromDate:date];
Below is my code
NSString *dateandtime =[NSString stringWithFormat:#"%#",self.eventtime];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEE, dd MMM yyyy HH:mm:ss Z"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateandtime];
if i print my self.event name i am getting the output as Mon, 7 Jan 2013 15:30:00 CST but when i pass this string in NSDateFormatter i am getting null value i don't know why i tried many combinations of date formats, but i cant solve it, can anyone help me
i solved my problem as Per Prateek comments, now its working for me...Thanks Prateek.
in your self.event, you are getting CST, it should be time zone for example +0530
Use :
[dateFormatter setDateFormat:#"EEE, dd MMM yyyy HH:mm:ss z"];
Use this code...
- (NSString *)formattedDate:(NSString*)dateSte {
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[NSTimeZone resetSystemTimeZone];
NSTimeZone *gmtZone = [NSTimeZone systemTimeZone];
[dateFormatter setTimeZone:gmtZone];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *date = [dateFormatter dateFromString:dateSte];
[dateFormatter setDateFormat:#"EEE,MMM d,''yyyy"];
NSString *strDate = [dateFormatter stringFromDate:date];
return strDate;
}
Use the below method for getting the NSDate from NSString date
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [self convertStringToDate:dateandtime];
Paste this below method in your .m file...
-(NSDate *)convertStringToDate:(NSString *) date {
NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
NSDate *nowDate = [[[NSDate alloc] init] autorelease];
[formatter setDateFormat:#"EEE, d MMM yyyy HH:mm:ss 'CST'"];// set format here format in which the date should be
date = [date stringByReplacingOccurrencesOfString:#"+0000" withString:#""];
nowDate = [formatter dateFromString:date];
// NSLog(#"date============================>>>>>>>>>>>>>>> : %#", nowDate);
return nowDate;
}

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);
I try to get and manage date with NSDateFormatter but how to make it works.
I think it's a problem with my first "dateFormatter" which have not the right format, because when I use the second formatter with function "stringFromDate" and paramter "[NSDate date]" it works well, but not when I use my NSDate "dateFromString".
//"dateString" have this format: "2011-05-26T16:18:26Z"
NSString *dateString = [[tracks objectAtIndex:0] objectForKey:#"to-date"];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEE, MMM d, yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
[dateFormatter release];
dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEE, MMM d, yyyy"];
//NSString *toDate = [dateFormatter stringFromDate:dateFromString];
NSString *toDate = [dateFormatter stringFromDate:[NSDate date]];
Thank you for your help :)
Well of course, the DateFormat is not the same as the one you are receiving from the server.
Try this:
dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss Z"];
NSDate *date = [dateFormatter dateFromString:[dateString stringByReplacingOccurrencesOfString:#"Z" withString:#" +0000"]];
Assuming that to-date is a string and not already an NSDate try this instead:
//"dateString" have this format: "2011-05-26T16:18:26Z"
NSString *dateString = [[tracks objectAtIndex:0] objectForKey:#"to-date"];
NSDate *dateFromString = [[NSDate dateFromString:dateString];
If you want to display a date to the user formatted in a particular format you can then use set up an NSDateFormatter and use stringFromDate: to get a string to show the user. If it still doesn't display correctly set the calendar (I forget if you always have to set it or if there is a default).
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];
