通用的解决方案是将你的设备连接到Mac上，然后观察安装过程中发生了什么。我得到一个错误:

Could not load download manifest with underlying error: Error Domain=NSURLErrorDomain Code=-1202 "Cannot connect to the Store" UserInfo=0x146635d0 {NSLocalizedDescription=Cannot connect to the Store, NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, NSLocalizedFailureReason=A secure connection could not be established. Please check your Date & Time settings., NSErrorFailingURLStringKey=https://myserver.com/app/manifest.plist, NSUnderlyingError=0x14678880 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “myserver.com” which could put your confidential information at risk.", NSURLErrorFailingURLPeerTrustErrorKey=, NSErrorFailingURLKey=https://myserver.com/app/manifest.plist}

错误中甚至有检查日期设置的建议。不知什么原因，那天是1970年1月1日。设置正确的日期就解决了这个问题。

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>
      ...

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。

我可以确认它的工作，但你必须把html和plist的dropbox。 它也适用于非企业OTA，即你想要与你的开发团队共享应用程序。

我做了:

a)在我的网站上，我用这个链接做了一个页面:

．． href="https://dl.dropboxusercontent.com/u//(your DB id)/ipa.html

b)在DropBox上我写了另一个HTML页面:

. .https://dl.dropboxusercontent.com/u/(your DB id)/MyApp.plist"> . DB id " 点击“安装MyApp”

c)在DropBox上移动plist，但让它指向我的旧服务器(没有https)

进一步Mark Parnell的回答，一个快速而又不太规范的解决方法是将manifest plist放入Dropbox，然后使用Dropbox的web界面来获得直接的https链接(“分享链接”->“获取链接”->“下载”)。

真正的ipa可以保留在你经常饮用的地方。在将plist的URL插入itms- services URL的查询之前，您需要对其进行URL编码(尽管只需要将任何&s替换为%3D就可以了)。

一个缺点是安装对话框现在会显示“dl.dropbox.com想要安装[任何]”。
