MDM推送設定值到 iOS device

透過 mdm 派送 settings 到 iOS app 的方法是透過 ApplicationConfiguration 指令來派送,ApplicationConfiguration指令要能正確執行的前提是:

  1. 要被派送settings 的 App Identifier 要存在
  2. 被派送 settings 的 app 必需是被管控制。
    (透過 InstallApplication command 去安裝)

出錯之後,MDM 告訴我們的Error Message:

 <key>Settings</key>
 <array>
 <dict>
 <key>ErrorChain</key>
 <array>
 <dict>
 <key>ErrorCode</key>
 <integer>12038</integer>
 <key>ErrorDomain</key>
 <string>MCMDMErrorDomain</string>
 <key>LocalizedDescription</key>
 <string>App「app id」不受管理。</string>
 <key>USEnglishDescription</key>
 <string>The app “app id” is not managed.</string>
 </dict>
 </array>

Managed app configuration changes that are pushed down from an MDM server appear in NSUSerDefaults so you can add an observer to be alerted of any changes to NSUserDefaults. The Managed app configuration dictionary pushed down from the MDM server is stored in the key named: com.apple.configuration.managed

Your application can also send a dictionary containing the feedback to the MDM server. The dictionary that is sent back to the MDM server as feedback must be stored in this key com.apple.feedback.managed

In order to test all of this you would need a device that is managed by an MDM server and the application must be installed by the MDM server that supports ApplicationConfiguration setting and ManagedApplicationFeedback commands.

The sample application’s readme.txt file recommends seeing the WWDC 2013 Session 301 “Extending Your Apps for Enterprise and Education Use” for a demo of this application.


to read the config (swift 3):

if let managedConf = UserDefaults.standard.object(forKey: "com.apple.configuration.managed") as? [String:Any?] {
    if let serverURL = managedConf["serverURL"] as? String{
        return serverURL
    }
}
if let serverURL = Bundle.main.object(forInfoDictionaryKey: "serverURL") as? String {
    return serverURL
}
return  "https://apple.com/"

as you can see – the app needs to manually enable reading from MDM bundle configuration.

P,S: only managed apps can get those configs.
