Format NSString 2015-05-24T20:10:00.000Z to M/d, h:mma (5/24, 8:00PM)

Question

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);

How the date format you used match the `NSString` format you got? — Larme, May 25 '15 at 08:15
Are you trying to get an NSDate object from an NSString? You might want to mention that you're using NSDateFormatter too (I assume your using NSDateFormatter). If you're using NSDateFormatter, I posted an answer below. — chrisamanse, May 25 '15 at 08:21
@Christophr I am having NSString @"2015-05-24T20:10:00.000Z from server I need to display it in the UILabel this format (5/24, 8:00PM) — Pandey_Laxman, May 25 '15 at 08:25

For the second part, 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. Then put that string in UILabel's text — chrisamanse, May 25 '15 at 08:29
But after setting dateFormat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZZ then dateFromString is always nil So later i can again setDateFormatter to "M/d, h:mma" to get desired output — Pandey_Laxman, May 25 '15 at 08:54

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];

Format NSString 2015-05-24T20:10:00.000Z to M/d, h:mma (5/24, 8:00PM)
