mask flexibility

[HamiltonSantos]

I could't figure out how to implement a mask for phones with 8 OR 9 digits as it needs the mask (##) ####-#### in one case and (##) #####-#### in other, is it possible using your framework?

Hi, you solved this? Can you help me?

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`
