需求是用户填写手机号时自动添加空格, 如:180 0000 0001

实现:

{    NSInteger _num;}

    _num = 0;    [self.mobileTextField addTarget:self action:@selector(textFieldDidEditing:) forControlEvents:UIControlEventEditingChanged];

// 以3 4 4格式显示手机号: 133 3333 4567-(void)textFieldDidEditing:(UITextField *)textField{    if (textField == self.mobileTextField) {        if (textField.text.length > _num) {            if (textField.text.length == 4 || textField.text.length == 9 ) {//输入                NSMutableString * str = [[NSMutableString alloc ] initWithString:textField.text];                [str insertString:@" " atIndex:(textField.text.length-1)];                textField.text = str;            }if (textField.text.length >= 13 ) {//输入完成                textField.text = [textField.text substringToIndex:13];                [textField resignFirstResponder];            }            _num = textField.text.length;                    }else if (textField.text.length < _num){//删除            if (textField.text.length == 4 || textField.text.length == 9) {                textField.text = [NSString stringWithFormat:@"%@",textField.text];                textField.text = [textField.text substringToIndex:(textField.text.length-1)];            }            _num = textField.text.length;        }    }}

使用时获取真实的手机号:

NSString *phone = [self.bindingView.mobileTextField.text stringByReplacingOccurrencesOfString:@" "withString:@""];
