NSDateFormatter Convert String To Date Always Military Time - nsdate

Question

I have a string which represents a date stored in military time. I want to display this string in a label in 12 hr time. Here is my code snippet:
NSTimeZone *timeZone = [NSTimeZone localTimeZone];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setTimeZone:timeZone];
[dateFormat setDateFormat:#"MM/dd/yyyy hh:mm:ss"];
NSLog(#"Current Date: %#", [dateFormat stringFromDate:[NSDate date]]);
NSLog(#"Sent date: %#",[myPlanData valueForKey:#"planDate"]);
NSDate *aDate =[dateFormat dateFromString:[myPlanData valueForKey:#"planDate"]];
NSLog(#"Converted date is: %#",aDate);
NSString *planDateString = [dateFormat stringFromDate:aDate];
NSLog(#"The converted date string is: %#",planDateString);
planDateLabel.text=planDateString;
The output is:
Current Date: 06/28/2012 10:08:48 - (so my date formatter appears correct?)
Sent date: 06/30/2012 20:47:34 - (this is the value being sent)
Converted date is: (null) - (Here is where it breaks!)
The converted date string is: (null)
If i change my dateformat to
[dateFormat setDateFormat:#"MM/dd/yyyy HH:mm:ss"];
Everything goes smooth but I end up with Military time being displayed. I simply want to convet that to 12 hr time and display in a label

Answer 1

Well here is how i ended up fixing it
NSTimeZone *timeZone = [NSTimeZone localTimeZone];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setTimeZone:timeZone];
[dateFormat setDateFormat:#"MM/dd/yyyy HH:mm:ss"];
NSDateFormatter *dateFormatback = [[NSDateFormatter alloc] init];
[dateFormatback setTimeZone:timeZone];
[dateFormatback setDateFormat:#"MM/dd/yyyy hh:mm:ss a"];
NSLog(#"Current Date: %#", [dateFormat stringFromDate:[NSDate date]]);
NSLog(#"Sent date: %#",[myPlanData valueForKey:#"planDate"]);
NSDate *aDate =[dateFormat dateFromString:[myPlanData valueForKey:#"planDate"]];
NSLog(#"Converted date is: %#",aDate);
NSString *planDateString = [dateFormatback stringFromDate:aDate];
NSLog(#"The converted date string is: %#",planDateString);
planDateLabel.text=planDateString;
Not sure if this is the best or right way to do it but it works!
