原因：从上文分析得知，我们的应用使用了第三方的硬件支持或者第三方的应用服务，但是并没有第三方的授权，导致苹果怕担责任，所以需要我们去申请这个第三方的授权证书。
解决：
1.首先在IOS被拒页下方评论区，写下你的联系方式，联系时间和联系时区，还有联系语言，要求苹果官方联系你，方便沟通整改方案。
2.确认你的苹果开发者账号是否为个人账号还是公司账号。
3.如果是个人账号，你需要向第三方公司要求提供授权证书，明确表明是第三方公司授权给苹果账号的开户人，注意需要和你开户时填写的那一串文字要一致，比如说你开户的时候，填写的是中文拼音，那你就填中文拼音，不要填中文名。
4.如果是公司账号，你需要向第三方公司要求提供授权证书，明确表明是第三方公司授权给你公司，注意需要和你开户时填写的公司名称一致。
5.拿到授权证书后，把之前的提交取消，然后重新提交，记得把授权证书放入附件上，然后保存再提交，最后等待苹果审核即可。
