Date not displayed properly in the nib file - objective-c

Question

I have a string with value #"15/11/13". I need to display the same on the label in the nib file.
I am using the following code to display it
NSDateFormatter * df1 = [[NSDateFormatter alloc] init];
[df1 setDateFormat:#"yyyy-mm-dd"];
[df1 setDateStyle:NSDateFormatterShortStyle];
[df1 setTimeStyle:NSDateFormatterNoStyle];
[profile1 setLastPromotionDate:[df1 dateFromString:#"11/11/13"]];
Profile1 is a different class which has lastPromotonDate of type NSDate.
In the nib file I have a outlet to display date which is bound to lastPromotionDate.
When I run the app, the date displayed is Monday, 11 November 2013 12:00:00 AM India Standard Time.
Can I know what is the mistake here? What has to be done so the date displays in this format : 11/11/13

Answer 1

Try this:-
NSString *dateStr=#"11/11/13";
NSDateFormatter *format=[[[NSDateFormatter alloc]init]autorelease];
[format setDateFormat:#"dd/mm/yy"];
NSDate *dt=[format dateFromString:dateStr];
NSString *str=[format stringFromDate:dt];
NSLog(#"%#",str);

Answer 2

NSString *str = #"15/11/13";
// here we create NSDateFormatter object for change the Format of date..
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init] ;
// here set format of date which is in your output date (means above str with format)
[dateFormatter setDateFormat:#"yy/mm/dd"];
// here you can fetch date from string with define format
NSDate *date = [dateFormatter dateFromString: str];
dateFormatter = [[NSDateFormatter alloc] init] ;
// here set format which you want..
[dateFormatter setDateFormat:#"dd/mm/yy"];
NSString *convertedString = [dateFormatter stringFromDate:date];
//here convert date in NSString
NSLog(#"Converted String : %#",convertedString);
rofile1.text = convertedString;

Why not just set it as:
NSString *str = #"15/11/13";
[label setStringValue: str];
UPDATE:
To convert this string to NSDate of the same format use:
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:#"dd/mm/yy"];
NSDate * date = [df dateFromString:str];
To get back the string value of date from NSDate use:
NSString *dateStr = [df stringFromDate: date];
Also you may use this dateStr to set you label text as
[label setStringValue: dateStr];
or bind the label to "dateStr". (Do not bind it to "date" of NSDate type, I think this is where you are going wrong).
Use "date" variable that is of NSDate type for your server requests.
UPDATE:
Since you are binding your label to NSDate value, it displays the complete date in the way it is present in NSDate. To retrieve the value of that NSDate in your custom format, you need to use NSDateFormatter that will write the part of NSDate that we need in our format to a NSString.
Also if we convert a NSString to NSDate, it doesn't mean that date formatter will save the NSDate in our custom format, the format of the date formatter specify the format of our string so that NSDate could read the correct date from our custom formatted string. But NSDate will always save the date value in its own format.

We have something called DateFormatter under objects in the library. We can drag and drop that under the text cell if the label in the list view of the nib.
This data formatter converts the date format to string value which is used to display in the UI.
