You can use NSDateFormatter to parse any custom format 

NSDateFormatter *dateformatter = [[NSDateFormatter alloc] init];

dateformatter.dateFormat = @"HH':'mm':'ss";

NSString *mydate = @"09:45:56" 

NSDate *parseddate = [dateformatter dateFromString:mydate];

This should give you a date of "9.45 am today"

The Docs for NSDateFormatter are pretty good but you can find the specific formatter variants possible here. Its linked from the apple docs.

If I am understanding the question correctly, you want to format the text in HH:mm:ss format as it is being typed in a UITextField?

In that case, make your view controller a UITextFieldDelegate and implement this selector:

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string

Every time the user types a character, or deletes it, this method will be called. At that point, you can determine whether to format the string. For instance, after they've typed the second character, thus creating the hour component of 09, you can append a ":" to the string so that it looks like "09:".

Another option. Use this selector to format it after they've finished typing in the entire string:

- (void)textFieldDidEndEditing:(UITextField *)textField
