   Yeah, I made a new version of his class:
   `#import "SNMaskTextField.h"
   #define MaskPhone @"MaskPhone"

   NSString *kSNMaskTextFieldDefaultChar = @"#";

   @implementation SNMaskTextField

   • (instancetype)initWithCoder:(NSCoder *)coder
     {
     self = [super initWithCoder:coder];
     if (self) {
     self.mask = kSNMaskTextFieldDefaultChar;
     }
     return self;
     }

   • (instancetype)initWithFrame:(CGRect)frame
     {
     self = [super initWithFrame:frame];
     if (self) {
     self.mask = kSNMaskTextFieldDefaultChar;
     }
     return self;
     }

   • (BOOL)shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
     NSString * currentTextDigited = [self.text stringByReplacingCharactersInRange:range withString:string];

     //Guarda a mascara original, para alterar quando for telefone:
     NSString *maskTemp = _mask;
     if ([_mask isEqualToString:MaskPhone]){
     //Verifica se o proximo telefone esta sendo digitado novo digito.
     if (currentTextDigited.length >= 15){
     _mask = @"(##) #####-####";
     }else{
     _mask = @"(##) ####-####";
     }
     }

     NSUInteger onOriginal = 0, onFilter = 0, onOutput = 0;
     char outputString[([_mask length])];
     BOOL done = NO;

     while(onFilter < [_mask length] && !done)
     {
     char filterChar = [_mask characterAtIndex:onFilter];
     char originalChar = onOriginal >= currentTextDigited.length ? '\0' : [currentTextDigited characterAtIndex:onOriginal];
     switch (filterChar) {
     case '#':
     if(originalChar=='\0')
     {
     // We have no more input numbers for the filter. We're done.
     done = YES;
     break;
     }
     if(isdigit(originalChar))
     {
     outputString[onOutput] = originalChar;
     onOriginal++;
     onFilter++;
     onOutput++;
     }
     else
     {
     onOriginal++;
     }
     break;
     default:
     if (onOutput != currentTextDigited.length){
     // Any other character will automatically be inserted for the user as they type (spaces, - etc..) or deleted as they delete if there are more numbers to come.
     outputString[onOutput] = filterChar;
     onOutput++;
     if(originalChar == filterChar)
     onOriginal++;
     }
     onFilter++;
     break;
     }
     }
     outputString[onOutput] = '\0'; // Cap the output string
     NSString *value = [NSString stringWithUTF8String:outputString];
     self.text = value;

     _mask = maskTemp;

     return NO;
     }
     @end`
