datePicker.minuteInterval=5;
NSLog(#"Date");
////////
NSString *curDate=alarmData.date;
//Jan 14, 2011 11:37
NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:#"MMM dd, yyyy HH:mm"];
//Optionally for time zone converstions
[format setTimeZone:[NSTimeZone timeZoneWithName:nil]];
NSDate *da = [format dateFromString:curDate];
[datePicker setDate:da animated:YES];
any suggestions
#Ali try this and u will get the string from date
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"MMM dd, yyyy HH:mm"];
//conversion of NSString to NSDate
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [formatter dateFromString:curDate];
[formatter release];

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 a string that contain date:

NSString *birthday = /*2012-05-25*/;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"YYYY-MM-DD"];
NSDate *dateFromString = [dateFormatter dateFromString:birthday];
and in the dateFromString i get the date of today.
This works :
NSString *birthday = #"2012-05-25";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *dateFromString = [dateFormatter dateFromString:birthday];
NSLog(#"%#", dateFromString);
Outputs :
2012-01-25 11:36:38.157 dsv[2679:903] 2012-05-25 00:00:00 +0200
Please refer to the Apple guide for details.
I hope this helps u. try this

[dateFormatter setDateFormat:#"MM/dd/yyyy HH:mm:ss a"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSLog(#"%#", aStr);

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).

This is my code,

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 using the below code:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterFullStyle];
NSDate *today=[NSDate date];
NSString *string = [dateFormatter stringFromDate:today];
NSLog(#"%#",string);
[dateFormatter release];
This will not give me this format 03/20/11 11:24 AM(MONTH/DATE/YEAR HOUR:MIN), if i convert system date and time so the converted string should have such type of information 03/20/11 11:24 AM(MONTH/DATE/YEAR HOUR:MIN).? What should i do?
you should set the date format as,
[dateFormat setDateFormat:#"dd/MM/YYYY hh:mm a"];
Try doing this and u will get the format
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"MM/dd/yy HH:mm"];
NSDate *today=[NSDate date];
NSString *string = [formatter stringFromDate:today];
NSLog(#"%#",string);
[formatter release];
Good Luck!
