NSDateFormatter with default time zone gives different date than NSDate description method
(2 answers)
Closed 8 years ago.
NSString *str=#"2015-01-01 00:00:00”;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
[dateFormatter setLocale:[NSLocale currentLocale]];
[dateFormatter setFormatterBehavior:NSDateFormatterBehaviorDefault];
NSDate *dtConverted = [dateFormatter dateFromString:str];
if (dtConverted==nil) {
dtConverted=nil;
}
return dtConverted;
if my str=2015-01-01 00:00:00 then date return 2014-12-31 18:30:00 +0000
if my str=0000-00-00 00:00:00 then date return null
Please help me to resolve my problem. Need the same date as I do have in string.
NSString *str= #"2015-01-01 00:00:00";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd hh:mm:ss"];
NSDate *dtConverted = [dateFormatter dateFromString:str];
if (dtConverted==nil) {
dtConverted=nil;
}
return dtConverted;
its working perfectly fine and if you want 24 hour format use HH:mm:ss instead of hh:mm:ss

NSDateFormatter show wrong year
(1 answer)
Closed 5 years ago.
I want to convert date from 23 May, 2017 to 23-05-2017.
I have tried with the following code but it returns 25-12-2016.
NSDateFormatter *oldFormatter = [NSDateFormatter new];
[oldFormatter setDateFormat:#"dd MMM, YYYY"];
NSDate *oldDate = [oldFormatter dateFromString:dateStr];
NSDateFormatter *newFormatter = [NSDateFormatter new];
[newFormatter setDateFormat:#"dd-MM-YYYY"];
I am using Xcode 8.2.1.
Thank You.
You need to do below changes:
YYYY --> yyyy
Updated Code:
NSString *strInputDateString = #"23 May, 2017";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:#"dd MMM, yyyy"];
//Set new dateFormate
// 23-05-2017
NSDate *date1 = [dateFormat dateFromString:strInputDateString];
[dateFormat setDateFormat:#"dd-MM-yyyy"];
NSString *strOutputDateString = [dateFormat stringFromDate:date1];
NSLog(#"%#",strInputDateString);
NSLog(#"%#",strOutputDateString);

I am trying to convert my date string to NSDate but its return correct date and wrong time.
This is my code :
NSString *dateStr = #"2013-12-20 12:10:40";
// Convert string to date object
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: #"yyyy-MM-dd HH:mm:ss"];
NSDate *lastUpdatedate = [dateFormatter dateFromString:dateStr];
NSLog(#"lastUpdatedate : %#",lastUpdatedate);
It returns this :
lastUpdatedate : 2013-12-20 06:40:40 +0000
- [NSDate description] (which is called when passing it to NSLog) always prints the date object in GMT timezone, not your local timezone. If you want an accurate string representation of the date, use a date formatter to create a correct string according to your timezone.
As #Leo Natan said, - [NSDate description] always gives date in GMT timezone. If you want to convert into local timezone then use following code.
NSString *dateStr = #"2013-12-20 12:10:40";
// Convert string to date object
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter setDateFormat: #"yyyy-MM-dd HH:mm:ss"];
NSDate *lastUpdatedate = [dateFormatter dateFromString:dateStr];
NSLog(#"lastUpdatedate : %#",[self getLocalTime:lastUpdatedate]);
-(NSDate *) getLocalTime:(NSDate *)date {
NSTimeZone *tz = [NSTimeZone defaultTimeZone];
NSInteger seconds = [tz secondsFromGMTForDate: date];
return [NSDate dateWithTimeInterval: seconds sinceDate: date];
}
OUTPUT:
lastUpdatedate : 2013-12-20 12:10:40 +0000
NSString *dateStr = #"2013-12-20 12:10:40";
NSDateFormatter *dateFormatterTest = [[NSDateFormatter alloc] init];
[dateFormatterTest setDateFormat: #"yyyy-MM-dd HH:mm:ss"];
[dateFormatterTest setLocale:[NSLocale currentLocale]];
NSDate *d = [dateFormatterTest dateFromString:dateStr];
Set NSLocale in your code, and you get perfect result.
You can try this:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: #"yyyy-MM-dd HH:mm:ss"];
[dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];
NSDate *lastUpdatedate = [dateFormatter dateFromString:dateStr];
NSTimeInterval sourceGMTOffset = [[NSTimeZone systemTimeZone] secondsFromGMTForDate:lastUpdatedate];
lastUpdatedate = [lastUpdatedate dateByAddingTimeInterval:sourceGMTOffset];
NSLog(#"lastUpdatedate : %#",lastUpdatedate);
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"EEE,d MMM YYYY"];
[dateFormatter setLocale:[NSLocale currentLocale]];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:#"Sun,2 Nov 2014"];
output date from string giving wrong output like 2013-12-21 18:30:00 +0000
Let me guess, you are doing this to test the output:
NSLog(#"%#", dateFromString);
instead do:
NSLog(#"%#", [dateFormatter stringFromDate:dateFromString]);
This is because NSLog() will call [NSDate description] to format the date and that won't account for any formatting or time zone you may want.

NSDate from NSString gives null result
(3 answers)
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);
