如何在ios中清除文本字段,如何在文本框中删除用户首次按键上的所有内容？

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



    if([tfieldDOB.text length] == 4)
    {
        tfieldDOB.text=[NSString stringWithFormat:@"%@/",tfieldDOB.text];
    }
    else if([tfieldDOB.text length]==7)
    {
        tfieldDOB.text=[NSString stringWithFormat:@"%@/",tfieldDOB.text];

    }

    return YES;

}
