IVSMixedImageDeviceSource

Objective-C


@interface IVSMixedImageDeviceSource : NSObject

Swift

class IVSMixedImageDeviceSource : NSObject

A source for an IVSMixedImageDevice.

  • The image device for this source. This can be changed at runtime and the mixed device will immediately apply the new device to the source, having it adopt the source’s configuration. This can also be set to nil.

    Declaration

    Objective-C

    @property (nonatomic, strong, nullable) id<IVSImageDevice> device;

    Swift

    var device: (any IVSImageDevice)? { get set }

  • The configuration for this source. To update this, provide a new IVSMixedImageDeviceSourceConfiguration to the transition API.

    Declaration

    Objective-C

    @property (nonatomic, strong, readonly) IVSMixedImageDeviceSourceConfiguration *_Nonnull configuration;

    Swift

    var configuration: IVSMixedImageDeviceSourceConfiguration { get }

  • Unavailable

    Do not create instances of this class directly

    Declaration

    Objective-C

    IVS_INIT_UNAVAILABLE

  • Unavailable

    Do not create instances of this class directly

    Declaration

    Objective-C

    IVS_INIT_UNAVAILABLE

  • Creates a new IVSMixedImageDeviceSource with a required configuration and optional device.

    Declaration

    Objective-C

    - (nonnull instancetype)
    initWithConfiguration:
        (nonnull IVSMixedImageDeviceSourceConfiguration *)configuration
                   device:(nullable id<IVSImageDevice>)device;

    Swift

    init(configuration: IVSMixedImageDeviceSourceConfiguration, device: (any IVSImageDevice)?)

  • Transitions this source to a new configuration.

    Multiple concurrent transitions are not supported on the same source. If you initiate a second transition before the first is finished, the transition will start over from the original state and transition to the new state as if the first transition had never been made.

    If there are no devices attached to this source, the duration parameter will be ignored and the slot will be updated immediately.

    Declaration

    Objective-C

    - (void)transitionToConfiguration:
            (nonnull IVSMixedImageDeviceSourceConfiguration *)nextConfiguration
                         duration:(NSTimeInterval)duration
                       onComplete:(nullable void (^)(BOOL))onComplete;

    Swift

    func transition(to nextConfiguration: IVSMixedImageDeviceSourceConfiguration, duration: TimeInterval, onComplete: ((Bool) -> Void)? = nil)

    Parameters

    nextConfiguration

    The new configuration for this source
    duration

    The amount of time to animate the transition for
    onComplete

    An optional callback that will be called when the animation has completed. The boolean provided will be true if the transition finished, or false if it was interrupted.
