[Solved] How to display Comma separated and Fractional values in UITextfiled? [closed]

by


Since you want the UITextField to have a maximum of 7 integer digits, you’ll need to validate every modification, and prevent any that result in a number with > 7 integer digits. The simplest way I know to do that is the UITextFieldDelegate method shouldChangeCharactersInRange:

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

    NSString* modifiedFieldText = [textField.text stringByReplacingCharactersInRange:range withString:string] ;
    // Remove all characters except for the digits 0 - 9.
    NSString* filteredToDigits = [modifiedFieldText stringByFilteringCharactersInSet:[NSCharacterSet decimalDigitCharacterSet]] ;
    // Change textField's text only if the result is <= 9 digits  (7 integer digits and 2 fraction digits).
    if ( filteredToDigits.length <= 9 ) {
        // If you'd rather this method didn't change textField's text and only determined whether or not the change should proceed, you can move this code block into a method triggered by textField's Editing Changed, replacing this block with "return YES".  You'll need to once again filter textField's text to only the characters 0 - 9.
        NSNumberFormatter* numberFormatter = [NSNumberFormatter new] ;
        numberFormatter.numberStyle = NSNumberFormatterCurrencyStyle ;

        NSNumber* asNumber = @( filteredToDigits.doubleValue / 100.0 ) ;
        textField.text = [numberFormatter stringFromNumber:asNumber] ;
    }
    // This method just changed textField's text based on the user's input, so iOS should not also change textField's text.
    return NO ;
}

I used an NSString category to change @”$12,345.67″ into @”1234567″.

NSString+Filter.m

- (NSString*) stringByRemovingCharactersInSet:(NSCharacterSet*)charactersToRemove {
    return [[self componentsSeparatedByCharactersInSet:charactersToRemove] componentsJoinedByString:@""] ;
}
- (NSString*) stringByFilteringCharactersInSet:(NSCharacterSet*)charactersToKeep {
    NSCharacterSet* charactersToRemove = [charactersToKeep invertedSet] ;
    return [self stringByRemovingCharactersInSet:charactersToRemove] ;
}
