一些好人通过使用Class 1 StartSSL证书和共享Apache配置来处理这个问题，该配置添加了证书支持(将与任何证书一起工作)和更改现有*中的链接的代码。Plist自动文件。太长了，不能复制，所以这里是链接: http://cases.azoft.com/how-to-fix-certificate-is-not-valid-error-on-ios-7/

我也遇到了同样的麻烦，照上面说的做了。

Put the plist in dropbox. Over the download file button, below an image of the document with mouse right button select the copy link action. This link is already something like https://dl.dropboxusercontent.com/s/xyz123/app.plist?stuff=stuff with many params. Remove the parameters (kept only address between https and .plist) Browse for url encode online, selected one of those links, copy, paste, execute, then the resulting text copied and pasted into the html where I have the itms-services link. By the way I have this html in two different locations, one of those is where the ipa is located. Make sure the plist includes absolute references to the ipa file.

这两个页面都成功地在ios 7.1的iphone上安装了应用程序

但是，现在安装了ios 7.0x的iphone无法安装该应用程序。

我创建了一个新问题:升级后的adhoc应用部署在7.1之前的ios上无法工作

这两个问题紧密相关，也因缺乏官方参考而联系在一起。

我通过将iPad连接到计算机并在试图安装应用程序时通过XCode Organizer查看控制台发现了这个问题。错误原来是:

无法加载非https清单URL: http://example.com/manifest.plist

在iOS 7.1中，清单的URL。plist文件必须是HTTPS，而我们使用的是HTTP。将URL更改为HTTPS解决了这个问题。

I.e.

itms-services://?action=download-manifest&url=http://example.com/manifest.plist

就变成了

itms-services://?action=download-manifest&url=https://example.com/manifest.plist

我假设您必须拥有有关域的有效SSL证书。我们已经做过了，但我想没有它你会有问题。

除了使用Dropbox进行企业推广，你还可以使用TestFlight进行企业签名应用的推广。

对于托管和分发临时开发版本和企业版本来说，这是一个非常棒的服务。

在阅读这篇文章后，我仍然有一个下载我的应用程序的问题。问题是由于自签名SSL证书。

我找到了解决这个问题的办法。您需要上传扩展名为'的证书文件。Crt '，并在移动safari中输入它的地址。系统询问您是否将证书添加到受信任证书列表。在此操作之后，您将能够安装您的特别应用程序。

Our team uses dropbox for ad-hoc distribution which uses https but still our app was failing to install. After much trouble-shooting we realized that the title field is required too. Whenever we sent out a link without this field safari ignored the link and did not prompt the user to install. Sometimes for quick development tests we skipped over the title node in the xml and not populate it. In case this is helpful for anyone having this issue make sure that your .plist contains the following nodes populated:

      ....
     <string>software</string>
    <key>title</key>
     <string>Your App Name</string>
      ...
