Some time ago, the customer was asked for help, primarily about the inability to install enterprise apps online through Safari. After a series of tests did not find the same phenomenon, and finally found that customers use the Restore function, the ipad iOS upgrade to 7.1. Search on the Internet, found that starting from iOS7.1, before using the Itms-services://url method of online installation of the IPA file is invalid, mainly in the click Installation, the error is: "Cannot install the application, because the xxx.com certificate is invalid." The main reason is that Apple modified the access protocol for the Manifest.plist file in iOS 7.1, accessing the original HTTP protocol and upgrading to HTTPS protocol access. In this respect, we need to modify the original access agreement ourselves. For example, the previous link code is:itms-services://?action=download-manifest&url=http://example.com/manifest.plistafter iOS 7.1, you need to change to:itms-services://?action=download-manifest&url=HTTPS://example.com/manifest.plistAdditionally, an SSL certificate is required to enable the ability to install the IPA file online. Although on-line to see someone with self-signed SSL certificate to implement the online installation, they have not yet realized, pending research.
