Convert string into date in ios

Question

I have my data in JSON format which contains some date:

"NOME_PUBBL_LINEA" = "FOLLONICA - PIOMBINO";
    "ORA_ARRIVA" = "1899-12-30T06:45:00";
    "ORA_PARTE" = "1899-12-30T05:50:00";

I want to convert it like :

 ora_arriva = 6.45,
   ora_parte = 5.50

I have tried following :

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"YYYY-MM-dd'T'HH:mm:ss'+02:00'"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"Italy/Rome"]];
NSDate *dte = [dateFormat dateFromString:dataDic[@"ORA_ARRIVA"]];

But it is giving me like

1899-12-30 00:51:40 +0000

for ora_arriva.

Once you got the `NSDate dte`, change the format as you want, and convert to `NSString`. — Larme, Jun 24 '14 at 09:15
Also you need to know the time zone of the JSON date and set it in the date formatter object. — trojanfoe, Jun 24 '14 at 09:19
@trojanfoe I just want time in output...If I only fetch time from date string then...is it proper way to acheive output as I want only time — vivek bhoraniya, Jun 24 '14 at 09:22
You have to parse the date correctly first. Then you can use the answer from @Zhang to extract the time elements. — trojanfoe, Jun 24 '14 at 09:22

That format doesn't appear to match that required by the OP. – trojanfoe Jun 24 '14 at 09:17

dateFromString returns an NSDate. You need take that NSDate object and construct your time:

NSDate *myDate = [NSDate date];

NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

NSDateComponents *comp = [gregorianCalendar components:NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit fromDate:myDate];

NSLog(@"current time = %ld:%ld", [comp hour], [comp minute]);

Replace the myDate with your actual NSDate you got back from your dateFormatter

The issue is that the time is wrong, not that the OP is unable to extract hour/minute from the parsed date. — trojanfoe, Jun 24 '14 at 09:21

You need something like this

[dateformatter setDateFormat:@"MM-dd-yyyy hh:mm:ss"];
NSString *dateString = [dateformatter stringFromDate:adate];
