I want to get date format in style "6Mar2012 7:03:34 AM". Can anyone tell me how shall I get exact that date formatting string.I want to get it in iOS 5.0 from a NSDate Object.
Use NSDateFormatter with the format string dMMMyyyy h:mm:ss a:
NSDate *today = [NSDate date];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dMMMyyyy h:mm:ss a"];
NSString *dateString = [dateFormat stringFromDate:today];
[dateFormat release];

"2014-02-03T23:10:00Z"
I'm aware of what each of the numbers represents, but the T and Z throw me off. Does anyone know what type of date format this is? I'd rather use a native parser if I could find one.
Thanks
It is an ISO 8601 format (http://en.wikipedia.org/wiki/ISO_8601).
T is Time delimeter while Z is used if time zone is UTC.
It appears to be ISO 8601 format. RestKit has a parser for it. You should also be able to get NSDateFormatter to parse it.
"2014-02-03T23:10:00Z" is the ISO 8601 format (http://www.w3.org/TR/NOTE-datetime)
the T represents the beginning of the time and the Z represents that the date is expressed in UTC (Coordinated Universal Time)
if you want to get the date with a specific format you could use NSDateFormatter
NSDate *now = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy/MM/dd"];
NSString *stringDate = [dateFormatter stringFromDate:date];
NSLog(#"%#", stringDate); // 2014/03/03
If you need just a certain part of the date (e.g just the current month):
NSDate *now = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MM"];
NSInteger *monthNumber = [[dateFormatter stringFromDate:date] integerValue];
NSLog(#"%i", monthNumber); // 03
If you need the date in a specific language:
NSDate *now = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd' de 'MMMM' del 'yyyy"]; // You can add your own text between single quotes
[dateFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:#"es_ES"]];
NSString *stringDate = [dateFormatter stringFromDate:date];
NSLog(#"%#", stringDate); // 03 de febrero del 2014
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 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 am using following code to generate NSDate -> NSString
+(NSString *)getCurrentTime
{
NSDate *now = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd-MM-yyyy hh:MM:SS a"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSString* str =[dateFormatter stringFromDate:now];
[dateFormatter release];
NSLog(#"%#",str);
return str;
}
everything is fine in above code. I am using above code to store string in Database. Now while retrieving that string gives me NULL. Following is my code to retrieve date in specific format
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"hh:MM:SS a"];
[dateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSDate *dt =[dateFormatter dateFromString:crdInfo.swipeTime];
NSLog(#"Date : %#",dt);
[dateFormatter release];
How should I retrieve or store with particular format?? My crdInfo.swipeTime is retrieving String propertly...
First off, why not just store the NSDate object or epoch timestamp? This will give you much more flexibility in the future.
Now to your problem, I suspect it is due to your configuration of the NSDateFormatter, you're saving it in one format and trying to convert it to a date using a different format. Make the formats the same and try again. If you want to display it differently than it is stored you're likely going to need to convert it to and NSDate using the stored format and then again use another date formatter to get it in the format you want it as a string.
As Narayana suggested you need to retrieve the date with same format as you have stored. Retrieve it as below : -
NSDateFormatter *reDateFormatter = [[NSDateFormatter alloc] init];
[reDateFormatter setDateFormat:#"dd-MM-yyyy hh:MM:SS a"];
[reDateFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSDate *dt = [reDateFormatter dateFromString:str];
NSLog(#"The Date : %#",dt);
[reDateFormatter setDateFormat:#"hh:MM:SS a"];
NSString *currentTime = [reDateFormatter stringFromDate:dt];
NSLog(#"%#",currentTime);
Hope it helps you.
Try to format it to dd-MM-yyyy hh:mm:ss a.
You wrote dd-MM-yyyy hh:MM:SS a where MM in hh:MM:SS gives month which is unrecognized in this format and there is no point writing upercase SS for seconds
Hope you understand it.
My date is coming in string format from server
Output of date come like this "07/30/2011",
I want a date format "30 july"
how can i do that?
Easy, use NSDateFormatter
Example,
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:#"MM/dd/yyyy"];
NSDate *date = [dateFormatter dateFromString:#"07/30/2011" ];
[dateFormatter setDateFormat:#"dd MMM"];
NSString *output = [dateFormatter stringFromDate:date];
