How to compare two NSDates: Which is more recent?
(13 answers)
Closed 9 years ago.
I am trying to compare two dates whether which one is the new or old, my dates are in following format:
2013-06-03 09:30:35
(YYYY-MM-DD HH:MM:SS)
Please give me some ideas, both are currently in string format?
So is that possible to convert ad check?
Convert that strings into NSDate using dateFormatter.
You can check this link Here is good discussion of your problem
How to compare two NSDates: Which is more recent?
try this
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];
// voila!
dateFromString = [dateFormatter dateFromString:dateString];
[dateFormatter release];
NSDate convert to NSString:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd-MM-yyyy"];
NSString *strDate = [dateFormatter stringFromDate:[NSDate date]];
NSLog(#"%#", strDate);
[dateFormatter release];
Please read this
enter link description here
if ([yourFirstDate compare:secondDate] == NSOrderedDescending) {
NSLog(#"yourFirstDate is later than secondDate");
} else if ([yourFirstDate compare:secondDate] == NSOrderedAscending) {
NSLog(#"yourFirstDate is earlier than secondDate");
} else {
NSLog(#"dates are the same");
}

I need to convert a date string "2015-03-10 00:00:00.000"(string from web service) to NSDate. I have used code like this
NSDateFormatter *fromDateFormat = [[NSDateFormatter alloc] init];
[fromDateFormat setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
NSDate *outputDate = [fromDateFormat dateFromString:#"2015-03-10 00:00:00.000"];
outputDate is nil. I tried without last triple zeros, and it is working. but I can't remove that zeros, because it is from a service.
If you want convert string to date using This function
NSDate *current=[self convertStringToDate:data.strCreateDate formate:#"yyyy-MM-dd HH:mm:ss"];
Put this method in your projects
- (NSDate *)convertStringToDate: (NSString *)date formate:(NSString *)formate {
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:formate];
return [dateFormat dateFromString:date];
}
This is helpfult to you..

Converting an ISO 8601 timestamp into an NSDate: How does one deal with the UTC time offset?

Closed 7 years ago.
I have an NSString #"2015-05-24T20:10:00.000Z", and I am using an NSDateFormatter with the date format #"yyyy-MM-dd'T'HH:mm:ssZ", but it always returns nil.
I am using the following code, but the output is always (null).
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
// NSString *input = #"2013-05-08T19:03:53+00:00";
[dateFormat setDateFormat:#"yyyy-MM-dd'T'HH:mm:ssZ"]; //iso 8601 format
NSDate *date = [dateFormat dateFromString:[dictScheduleData valueForKey:#"scheduledOn"]]; // coming from the server 2015-05-24T20:10:00.000Z
NSLog(#"Date output: %#", date);
Try this dateFormat
#"yyyy-MM-dd'T'HH:mm:ss.SSSZ"
You have to match the string's date format. Use NSDateFormatter, then set the date format to match the string's date format. Then use dateFromString method.
to convert it to (5/24, 8:00PM), you can change NSDateFormatter's dateFormat to "M/d, h:mma", then use NSDateFormatter's method stringFromDate (the date you previously got, which should not be nil if done correctly). Then put that string in UILabel's text.
NSDate *currentTime = [NSDate date];
NSDateFormatter *timeFormatter = [[NSDateFormatter alloc] init];
[timeFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss"];
[timeFormatter setLocale:[NSLocale currentLocale]];
NSString *DateString = [timeFormatter stringFromDate:currentTime];

Changing date format on iOS
(2 answers)
Closed 8 years ago.
Was wondering if there is an easy conversion to take a date in the format dd/MM/yyyy and transform it to MM/dd/yyyy to display.
Current code tried is:
//in dd/MM/yyyy format string below.
NSString *stringToFormat = #"28/05/1991";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"MM/dd/yyyy"];
NSDate *date = [dateFormatter dateFromString:stringToFormat];
However, date will return nil in this situation. Any help would be appreciated. Thank you.
You'll have to "decode" and then "encode". You're currently trying to parse 28 as a month. Try this:
//in dd/MM/yyyy format string below.
NSString *stringToFormat = #"28/05/1991";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd/MM/yyyy"];
NSDate *date = [dateFormatter dateFromString:stringToFormat];
[dateFormatter setDateFormat:#"MM/dd/yyyy"];
[dateFormatter stringFromDate:date];

NSDateFormatter won't format strange date string
(3 answers)
Closed 9 years ago.
I have a string of the form "2013-05-12T15:38:20+00:00" but I can't work out why my date formatter won't convert it to an NSDate object. I have tried using "yyyy-MM-ddTHH:mm:ss+zz:zz" and a bunch of variations on it but no luck.
What would be the correct date format for this string?
Thanks
The correct date format for this string is "yyyy-MM-dd'T'HH:mm:ssz"
Thanks #Anupdas for pointing me to a similar question.
Use this format
NSDateFormatter *form = [[NSDateFormatter alloc] init];
[form setDateFormat:#"yyyy-MM-dd'T'HH:mm:sszzz"];
NSLog(#"notDate =====> %#",[form dateFromString:#"2013-05-12T15:38:20+00:00"]);
NSDate *notDate = [form dateFromString:[#"" stringByAppendingFormat:#"2013-05-12T15:38:20+00:00"]];
NSLog(#"notDate =====> %#",[form dateFromString:#"2013-05-12T15:38:20+00:00"]);
I hope it helps you
Try this code
your string
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-ddTHH:mm:ss+zz:zz"];
NSDate* date = [dateFormatter dateFromString:dateString];
Conversion of the NSString to a NSDate
Now here you change any format as you want
[dateFormatter setDateFormat:#"dddd - MMMM dd,yyy"];
NSString* myNiceLookingDate = [dateFormatter stringFromDate:date];
[dateFormatter release];

Converting NSString to NSDate (and back again)
I make a request to the flickr api and it returns me the date in the following format
"2013-02-01T06:25:47Z"
How do i convert this into NSDate format??
It's a simple one, converting NSString to NSDate we use NSDateformatter using dateFromString method. We need to provide the Dateformatter style with existing style for NSString
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd'T'HH:mm:ssZ"];
NSDate *date = [dateFormatter dateFromString:#"2013-02-01T06:25:47Z"];
NSTimeZone *pdt = [NSTimeZone timeZoneWithAbbreviation:#"PDT"];
[dateFormatter setTimeZone:pdt];
[dateFormatter setDateFormat:#"HH:mm:ss zzz"];
[dateFormatter setDateFormat:#"K:mm a, z"];
NSString * updated String = [dateFormatter stringFromDate:date];
You can use below function:
-(NSDate *)getDateFromString:(NSString *)pstrDate
{
NSDateFormatter *df1 = [[[NSDateFormatter alloc] init] autorelease];
[df1 setDateFormat:#"yyyy-MM-dd'T'HH:mm:ssZ"];
NSDate *dtPostDate = [df1 dateFromString:pstrDate];
return dtPostDate;
}
Hope, it will be helpful to you.
This function will accept your string date and return the NSDate value.
Cheers!
