不能上架到App Store的iOS应用 ，几乎每一个开发者的选择都是通过iOS签名这种内测渠道来完成APP的上架任务，最常用的就是企业签名、超级签名以及TF上架，其中最受欢迎的当属于企业签名了。不过企业签名会出现掉签的现象，那么企业签名掉签了该如何处理呢？今天我就来分享下关于签名掉签的原因是怎么一回事。

很多iOS用户在做企业签名时，首先都是考虑稳定性，这种想法没有错误，但真正决定企业签名的根本因素其实是价格。了解过签名的人应该都知道，企业签名的优势在于安装数量没有限制，对应用类型的限制也比较小，但劣势是容易掉签。

苹果企业签名掉签原因是什么？首先要知道一些App运营商们使用的企业签名服务的并非全部都是自有证书的，需要企业签名的一般都会通过签名供应商进行签名操作，其中有些做企业签名服务的是个人或是小服务商，他们都是“捡漏”得到一些证书，然后用较低的费用给需求者进行签名，这种证书质量是没有保障的，很有可能刚签名完成就被封掉，于是企业签名也就掉签了，会导致App用户的流失，是很影响app正常运营的。企业签名的稳定性，我们只能通过使用稀有圈外证书、限制签名应用和类型来进行提高，而不能保证不掉签，当然稳定性越高，价格也就越高，很多用户会因为价格的原因而放弃选择，然后就只能面对频繁掉签的痛苦了。

企业签名之所以会出现频繁掉签的原因主要有以下三点

第一点就是一本企业证书上签名了大量的应用，或者装机量过大，这样很容易被系统检测到，被查出有违规操作，那么证书被撤回也就是分分钟的事。

第二点就是证书签名的应用中有违规的应用被举报，有些个人或小工作室不管签名应用的类型，什么都给进行企业签名，所以如果其中存在违规应用被举报，那么企业证书也会被吊销。

第三点是证书自身，企业签名后的应用在证书到期后，就是不能使用了。

以上内容就是关于企业签名掉签原因的分析，掉签是因为苹果签名市场鱼龙混杂，所以导致行业内证书是混乱的，企业签名不限制数量和类型，很多不限制的应用进行签名所以证书被收回了。所以我建议app运营者在选择签名服务商时要认准正规平台，选择专业服务的平台进行操作，这样才有保障，才可以为app保驾护航。
