You need to use a NSDateFormatter. I encourage you to read the class reference as linked by Kay.

Here's how you'd do it. I'm assuming the date is originating as a NSString.

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MM-dd-yyyy HH:mm:ss"];
NSDate *myDate = [df dateFromString:yourNSString]; 
NSString *myNewDate = [formatter stringFromDate:myDate];
[formatter release];
[myDate release];
