【报Bug】ios系统里测试抖音小程序用户信息授权返回后所有switchTab和navigateTo都失效，不能跳到指定页面或返回。开发工具和安卓都没问题，就iOS真机有问题

示例代码：

<template>
<view class="container">
<view class='header'>
<open-data type="userAvatarUrl" v-if="platform==1"></open-data>
<image src="../../static/logo.png" v-if="platform==6"></image>
</view>
<view class='content'>
<view>为了提供更好的服务，请点击下方授权登录</view>
<text>获得你的公开信息(昵称，头像等)</text>
</view>
<button class='btns bottoms' lang="zh_CN" @click="redindex" v-if="is_login==0" >授权登录</button>
<button class="btns bottoms" open-type="getPhoneNumber" @getphonenumber="onGetPhoneNumber" v-if="is_login==1" >绑定手机</button>
<button class='btns bottoms no-login' type="default" @click="goBack">返回</button>
</view>
</template>
