picker-view出现部分机型显示问题

部分手机会出现此问题，包括部分iphone,但是大部分手机都正常打开，该部分为省市二级联动选择器，根据picker-view组件开发

示例代码:

<view class="info-input-cell">

     <text>户籍所在地</text>

     <view class="info-input-box">

     <input type="text"

                name="register"

                bindtap="selectDistrict"

                data-tarname="Register" disabled

                placeholder="请选择"

                value="{{registerValue}}" />

     </view>

</view>

<!--城市二级联动-->

<view class="dialog-mask" style="z-index:11;visibility:{{addressMenuIsShow ? 'visible': 'hidden'}}" bindtap="hideCitySelected" />

<view class="animation-element-wrapper" animation="{{animationAddressMenu}}" style="visibility:{{addressMenuIsShow ? 'visible':'hidden'}}">

  <view class="animation-element">

    <text class="left-bt" catchtap="cityCancel">取消</text>

    <text class="right-bt" catchtap="citySure">确定</text>

    <view class="line"></view> 

    <picker-view class="area-picker-common" indicator-style = "height: 80rpx;" value="{{value}}" bindchange="cityChange">

    <!--省-->

      <picker-view-column>

         <view wx:for="{{provinces}}" wx:for-item="sheng" wx:key="{{index}}">

           {{sheng.rName}}

        </view>

      </picker-view-column>

      <!--地级市-->

      <picker-view-column>

        <view wx:for="{{cities}}" wx:key="{{index}}">

          {{item.rName}}

        </view>

      </picker-view-column>

    </picker-view>

  </view>

</view>

请用多几部手机测试，因为是部分手机出现该问题
