Thanks for great solution, I needed to use a different mask like the following:
mask=@”9 (999) 999 99 99″ and I was wondering about the changes I need to make to the code.
thanks again,

First of all thanks a lot for this snippet. I ill add a little functionality to work with spaces :

1 – add a flag to the begining of :

- (void)formatInput:(UITextField*)aTextField string:(NSString*)aString range:(NSRange)aRange

ej:
int flag =0;

if (! [regextest evaluateWithObject:_mask]) {
set the flag to 1
flag = 1;

3.
in the
if (aRange.location + 1 < [self.mask length]) {

set the _mask to
_mask = (temp ==1) ? [self.mask substringWithRange:NSMakeRange(aRange.location+1, 1)]:[self.mask substringWithRange:NSMakeRange(aRange.location-1, 1)];

And voila!
works great

Works, but needs to be “if(_aRange.location + 1 < [self.mask length]){" on the first line… Thanks!

To setup the mask you only need to call initWithMask as you did in your previous comment.

Great thanks! Can you also post a short example of setting the mask? Just want to make sure I’m setting it correctly.

Is must make the proper changes in the code to get spaces working in masks, let me do it here and I’ll update to code on blog post.

Is there a way to format with an embedded space like in the phone example above? Could you provide an example of what the mask looks like? Currently, I’m initializing the mask in the viewDidLoad by:

[self initWithMask@"(999) 999-9999"];

The desire is to have it automatically insert the space after the “)” is inserted. For example, the area code is 213 and the phone number is 543-9876. As the user types in the digits, it formats as follows:
User types: TextField Displays:
2 (2
1 (21
3 (213
5 (213) 5
4 (213) 54
3 (213) 543
9 (213) 543-9
8 (213) 543-98
7 (213) 543-987
6 (213) 543-9876

Wow I’ve been looking for sample code like this for a long time – thanks! Quick question: I’m assuming this can be used for telephone number formatting as the user types in the number? I’m looking for a way to format a telephone number similar to the built-in phone app, or similarly for entering phone numbers in contacts, where it will format as (U.S. style phone#) ###-####, or if more numbers entered, eventually as (###) ###-####. Can the mask be variable like this, or will it need to be specified as the end-result (###) ###-####? Thanks!
