Type	Description
System.Boolean

CameraDevice

The camera used by the image picker controller. The default is Rear

Declaration

public ISN_UIImagePickerControllerCameraDevice CameraDevice { get; set; }

Type	Description
ISN_UIImagePickerControllerCameraDevice

ImageCompressionFormat

Image compression format. Default value is JPEG

Declaration

public ISN_UIImageCompressionFormat ImageCompressionFormat { get; set; }

Property Value

Type	Description
ISN_UIImageCompressionFormat

ImageCompressionRate

Is ImageCompressionFormat is set tp JPEG compression format value will be applied.

The default value is 0.8f

Declaration

public float ImageCompressionRate { get; set; }

Property Value

Type	Description
System.Single

MaxImageSize

Max allowed image size. If bigger image is picked by user, image will be resized before sending to Unity. Most of the images in user photo library are big, so it's better to use this property to save some RAM.

The default value is 512

Declaration

public int MaxImageSize { get; set; }

Property Value

Type	Description
System.Int32	The size of the max image.

MediaTypes

An array indicating the media types to be accessed by the media picker controller.

Depending on the media types you assign to this property, the picker displays a dedicated interface for still images or movies, or a selection control that lets the user choose the picker interface. Before setting this property, check which media types are available by calling the GetAvailableMediaTypes(ISN_UIImagePickerControllerSourceType) class method.

If you set this property to an empty array, or to an array in which none of the media types is available for the current source, the system throws an exception.

You may use media type names from ISN_UIMediaType

Declaration

public List<string> MediaTypes { get; set; }

Property Value

Type	Description
List<System.String>

ModalPresentationStyle

The presentation style for modally presented view controllers.

The presentation style determines how a modally presented view controller is displayed onscreen. In a horizontally compact environment, modal view controllers are always presented full-screen. In a horizontally regular environment, there are several different presentation options.

The default value for this property is Automatic. For a list of possible presentation styles, and their compatibility with the available transition styles, see the ISN_UIModalPresentationStyle constant descriptions.

Declaration

public ISN_UIModalPresentationStyle ModalPresentationStyle { get; set; }

Property Value

Type	Description
ISN_UIModalPresentationStyle

SourceType

The type of picker interface to be displayed by the controller.

Prior to running the picker interface, set this value to the desired source type. The source type you set must be available and an exception is thrown if it is not. If you change this property while the picker is visible, the picker interface changes to match the new value in this property. The various source types are listed in the ISN_UIImagePickerControllerSourceType enumeration. The default value is PhotoLibrary.

Declaration

public ISN_UIImagePickerControllerSourceType SourceType { get; set; }

Property Value

Type	Description
ISN_UIImagePickerControllerSourceType

Methods

GetAvailableMediaTypes(ISN_UIImagePickerControllerSourceType)

Returns an array of the available media types for the specified source type.

Some iOS devices support video recording. Use this method, along with the IsSourceTypeAvailable(ISN_UIImagePickerControllerSourceType) method, to determine if video recording is available on a device.

Declaration

public static List<string> GetAvailableMediaTypes(ISN_UIImagePickerControllerSourceType sourceType)

Parameters

Type	Name	Description
ISN_UIImagePickerControllerSourceType	sourceType	The source to use to pick an image.

Returns

Type	Description
List<System.String>	The available media types.

IsSourceTypeAvailable(ISN_UIImagePickerControllerSourceType)

Returns a Boolean value indicating whether the device supports picking media using the specified source type. Because a media source may not be present or may be unavailable, devices may not always support all source types. For example, if you attempt to pick an image from the user’s library and the library is empty, this method returns false. Similarly, if the camera is already in use, this method returns false.

Before attempting to use an ISN_UIImagePickerController object to pick an image, you must call this method to ensure that the desired source type is available.

Declaration

public static bool IsSourceTypeAvailable(ISN_UIImagePickerControllerSourceType sourceType)

Parameters

Type	Name	Description
ISN_UIImagePickerControllerSourceType	sourceType	Source Type.

Returns

Type	Description
System.Boolean

Present(Action<ISN_UIPickerControllerResult>)

Presents a view controller modally.

If you configured the view controller to use Camera, the permission will be checked automatically, before presenting view controller. You can always do this yourself using the

Declaration

public void Present(Action<ISN_UIPickerControllerResult> callback)

Parameters

Type	Name	Description
Action<ISN_UIPickerControllerResult>	callback	Callback.

SaveScreenshotToCameraRoll(Action<SA_Result>)

Saves the screen screenshot to the saved photos album.

Declaration

public static void SaveScreenshotToCameraRoll(Action<SA_Result> callback)

Parameters

Type	Name	Description
