Strange issue of Date from String

A Strange issue :

I am converting a String into the Date by following code :

NSString *dateStr = @"02/10/2012 12:00:13 PM";

NSDateFormatter *dtF = [[NSDateFormatter alloc] init];
[dtF setDateFormat:@"MM/dd/yyyy HH:mm:ss a"];

NSDate *d = [dtF dateFromString:dateStr];
NSDateFormatter *dateFormatStr = [[NSDateFormatter alloc] init];

[dateFormatStr setDateFormat:@"MMMM dd, yyyy HH:mm a"];
NSString *strDate = [dateFormatStr stringFromDate:d];   
NSLog(@"Output:::-->%@",strDate);

I am using Xcode 4.2

Its working fine in Simulator and in Device iPhone 3Gs and iPad with iOS 5.0 and iPhone 4

But the issue is in iPod with iOS 5.0.1. In iPod it shows (null) value.

What is wrong in code ? OR is there any other issue ?

Solved !!!

The problem was in the date string NSString *dateStr = @"02/10/2012 12:00:13 PM";

The time is in 24hr format with "AM/PM" I think which was wrong. AM/PM should be with 12hr format.

So, I just removed AM/PM from string and it worked !!!

also from code : 

[dtF setDateFormat:@"MM/dd/yyyy HH:mm:ss"];

I've found that NSDateFormatter output can be erratic due to users' settings on their iPhones. You can force it to be standardised (I can't remember the details) by using this -

[dtF setLocale:enUSPOSIXLocale];

...makes the whole output more predictable.

Rather then a try aaa

Replace your code with following : 

NSString *dateStr = @"02/10/2012 12:00:13 PM";

NSDateFormatter *dtF = [[NSDateFormatter alloc] init];
[dtF setDateFormat:@"MM/dd/yyyy HH:mm:ss a"];

NSDate *d = [dtF dateFromString:dateStr];
NSDateFormatter *dateFormatStr = [[NSDateFormatter alloc] init];

[dateFormatStr setDateFormat:@"MMMM dd, yyyy hh:mm aaa"];
NSString *strDate = [dateFormatStr stringFromDate:d];   
NSLog(@"Output:::-->%@",strDate);

Output:::-->February 10, 2012 12:00 PM
