记录对接连连支付密码控件遇到的坑

    m_mytextfield1 = [[PassGuardTextField alloc] init];      
    m_mytextfield1.keyboardType = UIKeyboardTypeNumberPad;
    m_mytextfield1.placeholder = **nil**;
    m_mytextfield1.borderStyle = UITextBorderStyleRoundedRect;

//注:这里填写rsa公钥字符串
    [m_mytextfield1 setM_strInput2:];

//这里填写后台返回的random_value，里面的值会和rsa公钥匹配解密
    [m_mytextfield1 setM_strInput1:];

  //这里给后台传rsa加密的值
    NSString * stringText =[m_mytextfield1 getOutput4:1];
