Try like below:-

NSString *dateStr=@"October 24,Monday 12:30 AM EST";
[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"EST"]];
[dateFormat setDateFormat:@"MMMM dd,eeee HH:mm a z"];

NSDate *changeDate=[dateFormat dateFromString:dateStr];
NSLog(@"changeDate=%@",changeDate);
NSString *str=[dateFormat stringFromDate:changeDate];

//getting your local time
NSTimeZone *tz=[NSTimeZone localTimeZone];
//setting yourlocal time
[dateFormat setTimeZone:tz];
NSDate *date = [dateFormat dateFromString:str];
//Setting your desired format
[dateFormat setDateFormat:@"dd-mm Z"];
NSString *newDate=[dateFormat stringFromDate:date];
NSLog(@"new date=%@",newDate);

Try this...

NSDateFormatter *dateformat=[[NSDateFormatter alloc]init];
[dateformat setDateFormat:@"MMM dd,EEEE hh:mm a vvv"];
NSDate *datefor=[dateformat dateFromString:p];
[dateformat setDateFormat:@"MM-dd-yyyy hh:mm a"];

Answer 3

Your dateformat for October 24,Monday 12:30 AM EST is not correct. The correct dateformat in your case is MMMM dd,eeee HH:mm a z.

Working Code :

NSDateFormatter *dateformat = [[NSDateFormatter alloc] init];
[dateformat setDateFormat:@"MMMM dd,eeee HH:mm a z"];
NSDate *myDate = [dateformat dateFromString:@"October 24,Monday 12:30 AM EST"];

Take a look at Date Format Specifiers.

1. eeee - Local day of week spelled out.
2. MMMM - Month spelled out.
3. dd - day of month with no leading zeros.
4. HH - hour of day (24 hour format).
5. mm - minutes of hour (with leading zero) .
6. z - timezone (short wall time).
