Unity_iOSCameraPermission

Request native iOS camera permissions and get a callback method in Unity.

Installation

Download the latest ios_camera_permission.unitypackage file from the Release page, drag and drop it in your project folder and click import.

Prerequisites

• You must set a Camera Usage Description in the Player Settings.

Usage/Examples

If you want to ask camera permission and display the native iOS popup, call AskPermission().

The method signature is AskPermission(string gameObjectName, string callbackName) where gameObjectName is the name of the game object that will receive the callback via the Unity's build-in SendMessage() method. callbackName is the name of the method to call on the gameObject.

Note: It is recommended to use nameof(MyMethod) in the callbackName parameter to avoid errors when renaming or changing the callbacks.

public void AskPermission()
{
    iOSCameraPermission.AskPermission(gameObject.name, nameof(AskCallback));
}

void AskCallback(string permissionWasGranted)
{
    // permissionWasGranted will either be "true" or "false".
}

If you just want to verify the current permission for your app (useful to avoid asking when the permission is already granted), you can call VerifyPermision(). The method signature and callbacks are the same as AskPermission().

public void VerifyPermission()
{
    iOSCameraPermission.VerifyPermission(gameObject.name, nameof(VerifyCallback));
}

void VerifyCallback(string authorizationStatus)
{
    // authorizationStatus will be one of the following:
    // - Authorized
    // - Denied
    // - NotDetermined
    // - Restricted
}

Plugin directory structure

All .h and .m files must be in the follow location:

[ProjectName]/Assets/Plugins/iOS

Usage Sample

See Assets/iOSCameraPermission/Samples/SampleScene.unity

Each one of the two buttons in the scene has a UsageSample component and its OnClick() callback set to one of the two available methods.

Camera Usage Description is set to "Sample Camera Usage Description"
