I am building an application where I need to convert The NSString to NSDate. I have googled and found a lot links of SOF mentioned below -

Convert NSString to NSDate
Converting can NSString to NSDate format in objective C
I had used the answer given there but the problem I still facing is explain below step by step.
I had taken NSString *StringDate = #"01:00:00"; // I have declared time in the NSString variable.
I used the conversion method that mentioned in above link and stored the converted value to the NSDate variable.
When I am NSLog the NSDate variable. I am get "19:30:00" in my logcat. While the expected result should be "01:00:00".
Here is one of the code I am using
NSString *dateString = #"01:00:00";
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:#"hh:mm:ss"];
NSDate *dateFromString = [[NSDate alloc] init];
// voila!
dateFromString = [dateFormatter dateFromString:dateString];
-(NSString *)geTimeFromString:(NSString *)string
{
NSString * dateString = [NSString stringWithFormat: #"%#",string];
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"hh:mm:ss"];
NSDate* myDate = [dateFormatter dateFromString:dateString];
[dateFormatter setDateFormat:#"hh:mm a"];
[dateFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:#"en_US_POSIX"]];
NSString *stringFromTime = [dateFormatter stringFromDate:myDate];
return stringFromTime;
}
Try this
This is likely the correct date, but printed in a different timezone. I posted a longer explanation here:
Unexpected value from NSDate
BTW: In
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];
[[NSDate alloc] init] is completely meaningless, because you assign an instance of NSDate in the very next line.
Try this method to convert NSString to NSDate :-
- (NSDate*) convertStringToDate
{
NSString* dateStr = #"20/05/2015";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd/MM/yyyy"];
NSDate *date = [dateFormat dateFromString:dateStr];
return date;
}

I want to convert my input string to particular NSDate format,
Here is the code I have tried.
NSString * result;
NSDate * resultDate;
NSDate *date = [dateFormat dateFromString:maxUpcomingDateString];
NSDateFormatter *dateFormat1 = [[NSDateFormatter alloc] init];
dateFormat1.locale=[[NSLocale alloc] initWithLocaleIdentifier:#"en_US"];
[dateFormat1 setDateFormat:#"yyyy/MMM/dd"];
NSLog(#"maxUpcomingDateString %#",maxUpcomingDateString)
NSDate *d=[dateFormat1 dateFromString:maxUpcomingDateString];
result = [dateFormat1 stringFromDate:date];
resultDate=[dateFormat1 dateFromString:result];
NSLog(#"max1 date upcoming %#",result);
NSLog(#"max2 date upcoming %#", resultDate);
Output of my log shows:
maxUpcomingDateString 10 January 2017
max1 date upcoming 2017/Jan/10
max2 date upcoming (null)
I want the output date in the form of 2017/Jan/10. When I try to log the string it shows me the correct output but when I convert it back to NSDate it shows null.
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];
dateFromString = [dateFormatter dateFromString:dateString];
nsdate to nsstring
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd-MM-yyyy"];
NSString *stringDate = [dateFormatter stringFromDate:[NSDate date]];
NSLog(#"%#", stringDate);
add this code on dateFormat
[dateFormat setDateFormat:#"dd MMM yyyy"];
It will solve the problem.
Add this code after allocating the dateFormat object.
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd MMM yyyy"];
NSDateFormatter dateFromString fetched older date.
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *date = [dateformatter dateFromString:#"2015-05-18"];
The above function returns date as 2015-05-17 11:39:18 +0000 instead of
2015-05-18
Actually you are printing NSDate, if you are printing Date then compiler automatically convert your date to string by converting using current timezone. if you want actual converted date in NSString form then add one more line that convert NSDate to NSString like as bellowed.
NSDateFormatter * dFormatter = [[NSDateFormatter alloc] init];
[dFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *date = [dFormatter dateFromString:#"2015-05-18"];
NSLog(#"String : %#",[dFormatter stringFromDate:date]);
Output :
2015-05-18
this is working code to show the current date...might be solve your problem..you should go for this...
NSDate *Date = [NSDate date];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSString *dateFormated = [dateFormatter stringFromDate:Date];
NSLog(#"%#", dateFormated);
I tried to format a String from NSUserDefaults, which holds a Date.
The result is (null).
My question is: Is there a way to convert this String into a date to format it, or is there a better way?
My Code:
NSString *c = [prefs objectForKey:#"expiration_date_full"];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd.MM.yyyy HH:mm:ss"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:c];
cell.detailTextLabel.text = [NSString stringWithFormat:#"%# %# Noch gültig bis: %#", a, b, dateFromString];
You can store an NSDate in NSUserDefaults without conversion. That is, NSDate is one of the types supported by PLISTs. You can check the documentation for more info.
change your date format
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"MM-dd-yyyy"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:#"GMT"]];
NSDate* myTime = [dateFormat dateFromString:#"07-22-2014"];
NSLog(#"%#",myTime);
I have seen the other answer and question but i didn't find any useful answer for me.
I have a string like 2014-10-07T07:29:55.850Z and I want to have a date to compare each other.
If I use this code:
NSString *fullDate = payload[#"sent_ts"];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
dateFormat setDateFormat:#"yyyy-MM-ddTHH:mm:ss.SSSZ"];
NSDate *date = [dateFormat dateFromString:fullDate];
My date is nil. Why?
Try This.
NSString *dateString = #"2014-10-07T07:29:55.850Z";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];
NSDate *date = [dateFormatter dateFromString:dateString];
This question already has answers here:
NSDate from NSString gives null result

Closed 9 years ago.
My code is the following:
NSString *dateString = #"1339007317";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy"];
NSDate *date = [dateFormatter dateFromString:dateString];
NSString *year = [dateFormatter stringFromDate:date];
NSLog(#"%#",year);//null
How to fix that? thanx.
It is because you are using unix timestamp and you can convert unix timestamp into year or any date format as :
//Posted Date Format
NSString *dateStr = #"1339007317";
NSDate *date = [NSDate dateWithTimeIntervalSince1970:[dateStr doubleValue]];
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:#"en-US"];
NSDateFormatter *dateFormatter1 = [[NSDateFormatter alloc] init];
[dateFormatter1 setDateFormat:#"yyyy"]; //Here you can set any date format Ex:#"dd MMM, yyyy hh:mm a" or#"dd/MM/yyyyy" according to your requirement
[dateFormatter1 setLocale:locale];
[dateFormatter1 setTimeZone:[NSTimeZone systemTimeZone]];
dateStr = [dateFormatter1 stringFromDate: date];
Hope it helps you.
You need two date formats. The first should match the format of the string you wish to convert to an NSDate. The second format needs to represent the format you want. Use the 2nd to convert the NSDate to the new string.
Also, why do you create a date object then immediately replace it with a new one?
Change this:
NSDate *date = [[NSDate alloc] init];
date = [dateFormatter dateFromString:dateString];
to:
NSDate *date = [dateFormatter dateFromString:dateString];
Your code needs to be like this:
NSString *dateString = #"1339007317";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"???"]; // format that matches the dateString
NSDate *date = [dateFormatter dateFromString:dateString];
[dateFormatter setDateFormat:#"yyyy"]; // the desired new format
NSString *year = [dateFormatter stringFromDate:date];
NSLog(#"%#",year);
