iOS 7.1正式版发布了，之前使用itms-services://URL方式在线安装ipa文件的方法却失效了，点击的时候报错为：“无法安装应用程序，因xxx.com的证书无效”（错误界面见下图），这应该怎么解决呢？

其实iOS 7.1修改了manifest.plist文件的访问协议，之前可以通过http协议访问，在iOS 7.1之后必须使用https协议方式访问。

<a href="http://blog.sqstudio.com/wp-content/uploads/2014/03/ios7.1_https.jpg" class="highslide-image cboxElement" rel="example4" 955"="" style="text-decoration: none; color: rgb(1, 150, 227); cursor: url(http://blog.sqstudio.com/wp-content/plugins/auto-highslide/highslide/graphics/zoomin.cur), pointer; outline: none;">

比如之前的链接代码为：

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

在iOS 7.1之后，就需要修改为：

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

需要一个SSL证书才能够实现在线安装ipa文件的功能。

//-------------------  延伸： 关于https设置 ----------------------------------

1.upload your app.plist to dropbox

2.get shared link of app.plist, like https://www.dropbox.com/s/qgknrfngaxazm38/app.plist

3.replace www.dropbox.com with dl.dropboxusercontent.com in the link, like https://dl.dropboxusercontent.com/s/qgknrfngaxazm38/app.plist

4.write your download.html like <a href="itms-services://?action=download-manifest&url=https://dl.dropboxusercontent.com/s/qgknrfngaxazm38/app.plist">INSTALL!!</a>

5.upload the download.html to dropbox

6.get shared link of download.html, like https://www.dropbox.com/s/gnoctp7n9g0l3hx/download.html

7.replace www.dropbox.com with dl.dropboxusercontent.com in the second link as well, like https://dl.dropboxusercontent.com/s/gnoctp7n9g0l3hx/download.html

Now, visit https://dl.dropboxusercontent.com/s/gnoctp7n9g0l3hx/download.html in your device, you can install the app like before.

 

这个是通过上传dropbox来解决，事实上，只要找个可以以https方式共享外链的网盘，把plist文件上传就可以了！
