What's New

  • With MABS 7.1 you can define the Usage Descriptions required for the iOS apps at Application level (see the section iOS Usage Descriptions). (RPM-326)

  • We added the option to remove unwanted permissions when building applications without the Upload widget (see the section Upload Widget Permissions). (RPM-471)

  • In the iOS debug builds, you can now turn off the notification "Heads up! Enable OutSystems Developer Tools..." by setting the DisableInspectorNotification preference to true in the Extensibility Configurations. (RPM-968)


iOS Usage Descriptions

Add the Usage Descriptions to the JSON of Extensibility Configurations by inserting a name / value key pair, where the name ends in UsageDescription. MABS searches for preferences that end in UsageDescription and adds them to the Info.plist of your iOS app. For the available descriptions see Information Property List Key Reference by Apple.


To override the CameraPlugin Usage Description in an app, add the following to the Extensibility Configurations JSON of the app home module:

    "preferences": {
        "ios": [{
            "name": "NSCameraUsageDescription",
            "value": "This application makes use of the Camera because"

Upload Widget Permissions

All OutSystems apps can use the Upload widget. The consequence of this is that the native mobile apps require some default permissions, even without adding other plugins. In the apps without the Upload widget the requirements for the default permissions can sometimes add extra permissions to the app, such as the Camera permission. In MABS 7.1 you can use a new option to remove such permissions, by adding the AddUploadWidgetPermissions setting to the Extensibility Configurations JSON :

    "preferences": {
        "global": [{
            "name": "AddUploadWidgetPermissions",
            "value": "false"

Set the AddUploadWidgetPermissions to false only in the apps that don't use the Upload widget. If you later need the Upload widget in the app, add the widget and then set AddUploadWidgetPermissions to true and create a new build.
