This could be repeated one but I am not able to find the correct solution.
NSDateFormatter *dateFormat = [[[NSDateFormatter alloc] init] autorelease];
[dateFormat setDateFormat:#"YYYY-MM-dd"];
NSString *dateString = [dateFormat stringFromDate:receiveddate];
NSLog(#"Date: %#", dateString);
receiveddate is NSDate and its value is 2012-06-11 00:00:00 +0000
I just want to convert the above date into NSString where value should be just 2012-06-11
But when I checked it out it gives me different output that is 2012-00-11 00:00:00. It's strange. How can I get out from this problem.
You Can Use This :
[formatter setDateStyle:NSDateFormatterShortStyle];
[formatter setTimeStyle:NSDateFormatterNoStyle];
[formatter setDateFormat:#"yyyy-MM-dd"];
Hi I am using the same code what you have posted and it's giving me the right output what You want. So i think the problem with the format of your receiveddate. Here is tha code what i m using
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init] ;
[dateFormat setDateFormat:#"YYYY-MM-dd"];
NSString *dateString = [dateFormat stringFromDate:[NSDate date]];
NSLog(#"Date: %#", dateString);
OUTPUT:Date: 2012-06-06
use this
[dateFormat setDateFormat:#"YYYY-MM-dd"];
dateFormat.dateStyle = kCFDateFormatterShortStyle;
The problem I find out is 2012-06-11 00:00:00 +0000 is not a valid NSDate.
Maybe the problem is that you are using YYYY instead of yyyy ?
Atleast I'm using it like this: [mDateFormatter setDateFormat:#"yyyy-M-dd"]; to get 2012-6-5.

I want to convert date 2012-12-26 to december 26, 2012 in iOS?
I am using websrvice and the data comes in this format 1990-12-26.
I want to change this to december 26, 2012 format.
This is what I am doing:
lbl_Rightside.text = [rootElement stringValueForNode:#"date"];
NSLog(#"lbl_Rightside is %#",lbl_Rightside.text);
[lbl_Rightside release];
Getting date to this label on 1990-12-26. Now I want to change date to december 26, 2012 format.
Any hints from experts would be very welcome.
you can use NSDateFormatter to do this kind of things. First
convert your date String to a date object using dateFromString:
method.
from date convert to string you want using stringFromDate: method
Different format strings can be found here.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *orignalDate = [dateFormatter dateFromString:YOUR_ORIGINAL_STRING];
[dateFormatter setDateFormat:#"MMMM dd, yyyy"];
NSString *finalString = [dateFormatter stringFromDate:orignalDate];
[dateFormatter release]; //if not using ARC
Check the official Apple documentation about NSDateFormatter. You should use this class to do this kind of formatting.
by using NSDateFormatter
NSString to NSDate
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:#"yyyy-MM-dd"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
[dateFormatter release];
NSDate convert to NSString:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MMMM dd, yyyy"];
NSString *strDate = [dateFormatter stringFromDate:[NSDate date]];
NSLog(#"%#", strDate);
[dateFormatter release];
Try to look at NSDateFormatter Class,
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"]; // this is your input date format
NSDate *newDate = [dateFormatter dateFromString:dateString];//converting string to date object
The format you are looking for is something like:
[dateFormatter setDateFormat:#"MMM dd,yyy"]; // setting new format
NSLog(#"The date is = %#",[dateFormatter stringFromDate:newDate])
I am trying this since last two hours and finaly left it out for you guys :P
I need to convert this String Mon, 14 May 2012, 12:00:55 +0200
into Date dd/mm/yyyy hh:ss format..
Any kind of help towards the goal will be really appreciated.
What I have tried
I have tried using NSDateFormatter but I am unable to figure out the exact format of the above date.
This [dateFormatter setDateFormat:#"EEEddMM,yyyy HH:mm:ss"]; is how I have tried and many other formats too
Eg:
NSString *finalDate = #"Tue, 29 May 2012, 14:24:56 +0200";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEEddMM,yyyy HH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:finalDate];
Here the date alwasys comes as nil
The most important part of date formatting is often forgotten, tell the NSDateFormatter the input language:
NSDateFormatter *dateFormatter = [NSDateFormatter new];
[dateFormatter setDateFormat:#"EEE, dd MMMM yyyy, HH:mm:ss Z"];
dateFormatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:#"EN"];
NSDate *date = [dateFormatter dateFromString:#"Mon, 14 May 2012, 12:00:55 +0200"];
NSLog(#"date: %#", date);
I've checked the output: date: 2012-05-14 10:00:55 +0000
Be aware that the HH in the date formatter is for 24hr.
Now I would suggest not to use a fixed output scheme, but use one of the NSDateFormatterStyle:
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
NSString *dateString = [dateFormatter stringFromDate:date];
NSLog(#"date: %#", dateString);
Which in american english will output: 5/14/12 12:00 PM
This code is valid for ARC if you are not using ARC add autorelease to the NSLocale and release the NSDateFormatter after you are done with it.
NSDateFormatter *inputFormatter = [[NSDateFormatter alloc] init];
[inputFormatter setDateFormat:#"dd/mm/yyyy hh:ss"];
NSString *formatterDate = [inputFormatter stringFromDate:inDate];
[inputFormatter release];
get inforamtion about all Date Formate

hope,this help you....
I have a string that has a date format of HH:mm so for example it could 12:00 or 22:00, and I input that into my NSDateFormatter by setting it as the date format. I just need to construct a custom date. The problem is when I have done this and I get my parsed string as 2012-05-17 12:00:00 +0000 if the date is the 17th of May.
NSDate *today = [NSDate date];
NSDateFormatter *output = [[NSDateFormatter alloc] init];
[output setDateFormat:[NSString stringWithFormat:#"yyyy-MM-d %#:00 +0000",#"12:00"]];
NSString *finalTodayString = [output stringFromDate:today];
parsedDateString = [NSString stringWithString:finalTodayString];
The problem is when I parse it again to just include the HH:mm I get something totally different. For example if I have this code.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-d HH:mm ZZZ"];
NSDate *date = [dateFormatter dateFromString:fullDateString];
NSDateFormatter *dateFormmater2 = [[NSDateFormatter alloc] init];
[dateFormmater2 setDateFormat:#"HH:mm"];
NSString *string =[dateFormmater2 stringFromDate:date];
Then the string should be 12:00 but instead it becomes 14:00. Please help.
Remove the Greenwich Meridian time "+0000" from the first code
I'm working on an assignment that allows the user to display events that are happening 'today'. I have parsed the XML file and stored the contents into an array. The contents of the XML file consists of a title, description, date etc. The dates are in NSString format and I want to convert them into NSDates and compare them with today's date before displaying them in a UITableView.
I'm new to obj-c and I've searched online for help on NSDate, but I couldn't find what I need. Any links, advice or help on this is really appreciated. Thanks in advance (:
suppose dateString contains the date in string format
first get date from string:-
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"dd/mm/yyyy"];
NSDate *dateprevious = [formatter dateFromString:dateString];
Now get today date
NSDate *date=[NSDate date];
[formatter setDateFormat:#"dd"];
NSString *dateOfGame =[formatter stringFromDate:dateprevious];
NSString *todaydate =[formatter stringFromDate:date];
[formatter release];
if([todaydate isEqualToString:dateknown])
{
NSLog(#"date matched");
}
Depending on the format of the string, you can use this:
+ (id)dateWithNaturalLanguageString:(NSString *)string
To compare two dates you will find here a lot of usefull answers :)
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd-MM-yyyy , hh:mm a"];
[dateFormatter setDateStyle:NSDateFormatterLongStyle];
NSDate *date = [[dateFormatter datefromString:date] retain];
[dateFormatter release];
You can use this one
Have a look at NSDateFormatter
It has a method called dateFromString
Like you could do the following:
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"dd/mm/yyyy"];
NSDate *date = [formatter dateFromString:#"5/5/2011"];
I'm trying to format a NSDate to a string with date format of yyyyMMdd, here's the code
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyyMMdd"];
NSDate *date =data.createdTime;
NSLog(#"%#",date);
NSLog(#"%#",[dateFormatter stringFromDate:date]);
the NSLog return me this value
Tue, 24 May 2011 0:05:01 +0800
(null)
Anyone know which part is wrong?
Thanx in advance.
Perhaps currentArticle.createdTime is a valid date but data.createdTime is nil? In addition, you are performing the -setDateFormat: selector on dateFormat, but it seems like your date formatter is dateFormatter.
Try the following code:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: #"yyyyMMdd"];
NSDate *date = data.createdTime;
NSLog(#" Normal Date = %#", date);
NSLog(#"Formatted Date = %#", [dateFormatter stringFromDate: date]);
[dateFormatter release];
If date is nil, then both NSLog() calls will tell you.
Edit
Double check that data.createdTime is an NSDate instance. Perhaps it is an instance of another class, such as NSString, whose -description returns the displayed date. This would explain why NSLog() “shows” the date, but the formatter is returning nil.
BOOL isDate = [data.createdTime isKindOfClass: [NSDate class]];
NSLog(#"Date %# a date.", isDate ? #"is" : #"is not");
[dateFormat setDateFormat:#"yyyyMMdd"];
Should be:
[dateFormatter setDateFormat:#"yyyyMMdd"];
If it still isn't working then something is wrong with data.createdTime; because I ran this code and recieved the expected output:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyyMMdd"];
NSDate *date = [NSDate date];
NSLog(#"%#",date);
NSLog(#"%#",[dateFormatter stringFromDate:date]);
