First convert NSString to NSDate.

 NSDateFormatter *DateFormatter = [[NSDateFormatter alloc] init];
 NSTimeZone *timeZoneEDT =[NSTimeZone timeZoneWithName:@"GMT"];
 [DateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4];
 [DateFormatter setTimeZone:timeZoneEDT];
 [DateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss.SSS"];
 NSDate *CurrentDate = [DateFormatter dateFromString:DateStr];

Then convert GMT time to local time.

NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithName:@"Asia/Kolkata"];
[dateFormatter setTimeZone:sourceTimeZone];
NSString *dateRepresentation = [dateFormatter stringFromDate:dateFromString];

@athira try this. it works for me.

    NSDate *startDate = [NSDate date];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"dd/M/yyyy h.mm a"];
    [dateFormatter setTimeZone:[NSTimeZone localTimeZone]];
    NSString *timestamp = [dateFormatter stringFromDate:startDate];
    NSLog(@"date = %@",timestamp); //date = 14/9/2017 4.34 PM

it will print current time with proper GMT+5:30 and i have used localTimeZone.
