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
my Blog Link is http://parasjoshi3.blogspot.in/2012/01/date-formate-info-for-iphone-sdk.html
and also small function is bellow.....
-(NSString *) dateInFormat:(NSString*) stringFormat {
char buffer[80];
const char *format = [stringFormat UTF8String];
time_t rawtime;
struct tm * timeinfo;
time(&rawtime);
timeinfo = localtime(&rawtime);
strftime(buffer, 80, format, timeinfo);
return [NSString stringWithCString:buffer encoding:NSUTF8StringEncoding];
}
////////Like.......

I want to display date like Today, 25 Mar 2014 15:18, if the date is today's date.
Also expecting Tomorrow, 26 Mar 2014 15:18, if it is tomorrow's date and Wednesday, 27 Mar 2014 15:18, if it is day after tomorrow's date.
Anyone please help me.
Sample from developer.apple.com
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeStyle:NSDateFormatterNoStyle];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
NSLocale *frLocale = [[NSLocale alloc] initWithLocaleIdentifier:#"en_US"];
[dateFormatter setLocale:frLocale];
[dateFormatter setDoesRelativeDateFormatting:YES];
NSDate *date = [NSDate dateWithTimeIntervalSinceNow:60*60*24*1];
NSString *dateString = [dateFormatter stringFromDate:date];
NSLog(#"dateString: %#", dateString);
NSDateFormatter *detailFormatter = [[NSDateFormatter alloc] init];
[detailFormatter setLocale:frLocale];
[detailFormatter setDateFormat:#"dd MMM yyyy HH:mm"];
NSString *detailString = [detailFormatter stringFromDate:date];
NSLog(#"detailString: %#", detailString);
NSString *finalString = [NSString stringWithFormat:#"%#, %#",dateString, detailString];
NSLog(finalString);
Apple doesn't directly support using relative date combined with absolute date. What you'd have to do is to create two formatters, one with relative enabled and one without. Then compare the output strings (e.g. "Today" and "Mar 25") and if they are not equal, combine them: "Today, Mar 25", but if they are equal, just use one.
And as an aside, actually on "après-après-demain", I think you may have found a bug (either in docs or code). Do you actually set "après-après-demain"? I tried Apple's sample code:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeStyle:NSDateFormatterNoStyle];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];
NSLocale *frLocale = [[NSLocale alloc] initWithLocaleIdentifier:#"fr_FR"];
[dateFormatter setLocale:frLocale];
[dateFormatter setDoesRelativeDateFormatting:YES];
NSDate *date = [NSDate dateWithTimeIntervalSinceNow:60*60*24*3];
NSString *dateString = [dateFormatter stringFromDate:date];
NSLog(#"dateString: %#", dateString);
Which Apple says produces output of dateString: après-après-demain no matter what your language is set to (as it switches the date formatter to French).
But when I ran the code on both iOS and OS X, I get the actual date: Mar 28 (and if I change to *2, I get après-demain.
So, if you're seeing the same, I'd suggest filing a bug report with Apple.
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
NSDate *My_StartDate,*My_EndDate ;
NSDateFormatter * df= [[NSDateFormatter alloc]init];
[df setDateFormat:#"dd/MM/yyyy hh:mm:ss"];
My_StartDate = [df dateFromString:#"01/05/2010 10:15:33"];
My_EndDate = [df dateFromString:#"01/05/2010 10:45:33"];
NSLog(#"%#",My_StartDate);
NSLog(#"%#",My_EndDate);
In the log i get something like this for the my_startdate as 2010-05-01 04:45:33 +0000 and end date as 2010-05-01 05:15:33 +0000 instead i should have got value as for start date as 2010-05-01 10:15:33 +0000 and end date as 2010-05-01 10:45:33 +0000
Try with below function:
-(NSString *)getDateStringFromDate :(NSDate *)dateValue{
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"yyyy-MM-dd"];
NSDateFormatter *timeFormat = [[NSDateFormatter alloc] init];
[timeFormat setTimeStyle:NSDateFormatterShortStyle];
[timeFormat setDateFormat:#"HH:mm:ss"];
//[timeFormat setDateFormat:#"HH:mm"];
//[timeFormat setDateFormat:#"HH:mm a"];
////
NSString *theDate = [dateFormat stringFromDate:dateValue];
NSString *theTime = [timeFormat stringFromDate:dateValue];
NSLog(#"\n"
"theDate: |%#| \n"
"theTime: |%#| \n"
, theDate, theTime);
return theDate;
}
Change Format of data as per your need.
Let me know in case of any difficulty.
Cheers.
This shows date which follow American standard time string but by this reason you don't get any problem in making your logic.Also
[df setDateFormat:#"dd/MM/yyyy hh:mm:ss"];
this format using 12 hour format (means 2:03 pm and 2:03 am) and date object never use am and pm for showing date object value but when you convert it correctly then it gives you right date and time.
If you feel you get any problem then use different locale for that.
It is displaying asper the GMT+4.30 time.It displays like that only.When you are converting that date to string using the DateFormatter it gives the same date(Whichever you want like start date as 01/05/2010 10:15:33 and end date as 01/05/2010 10:45:33).
NSDateFormatter * dateformatter= [[NSDateFormatter alloc]init];
[dateformatter setDateFormat:#"dd/MM/yyyy hh:mm:ss"];
NSString *dat = [dateformatter stringfromDate:My_StartDate];
then you will get the output as 01/05/2010 10:15:33
You might want to set the time zone of the date formatter to GMT here. Do it using
[df setTimeZone:[NSTimeZone timeZoneWithName:#"GMT"]];
before you do dateFromString: calls. This will give you what you want.
Just need to update here in your code:
I might be like that your time would be in 24 hours format, so at that time you need to use this ....other than that you need to set the timezone.
Follow this link for All zone : http://unicode.org/reports/tr35/tr35-6.html#Date%5FFormat%5FPatterns
[df setDateFormat:#"dd/MM/yyyy hh:mm:ss"];
to
[df setDateFormat:#"dd/MM/yyyy HH:mm:ss"];
You are Done ;)
I am converting an NSString like #"12:25 AM May 27 2011" into NSDate.But as I convert it using the following code
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"hh:mm a MMM dd YYYY"];
NSDate *date = [[dateFormatter dateFromString:#"12:25 AM May 27 2011"] copy];
[dateFormatter release];
I get the wrong Date as 2010-12-25 19:25:00 +0000
Can anyone please help me around here
It's not a wrong date, the time is displayed GMT hance (+0000) if you set the correct timezone very thing will be oke.
