1》小程序ios页面晃动问题，上下晃动是因为机子本身问题，左右问题可以解决
.container{
padding-bottom: 0;
background-repeat: no-repeat;
background-size: 100% auto;
background-position: bottom center;
}
包个container
2》小程序倒计时60秒 以及倒计时的时候按钮无法点击 ，60秒之后重新
<form bindsubmit="formSubmit" bindreset="formReset">
<view class="weui-cells weui-cells_after-title">
<view class="weui-cell weui-cell_input">
<view class="weui-cellhd">
<view class="weui-label">手机号</view>
</view>
<view class="weui-cellbd">
<input class="weui-input"name="phone" placeholder="请输入手机号"/>
</view>
</view>
<view class="weui-cell weui-cell_input weui-cell_vcode">
<view class="weui-cellhd">
<view class="weui-label">验证码</view>
</view>
<view class="weui-cellbd">
<input class="weui-input" maxlength=‘6‘ name="yzm" placeholder="请输入验证码" />
</view>
