A Boolean value that determines whether a dual camera device delivers images from both cameras.
- iOS 11.0–13.0Deprecated
When this property is
NO (the default), and the photo output is configured with a capture device of the
AVCapture type, the photo output delivers a single main photo image for each capture. (The device determines how to produce that image from one or both cameras).
If you change this setting to
YES, your delegate’s
capture method fires at least twice for each main image—once for the telephoto image and again for the wide-angle image. Setting this property to true when not using a dual-camera device raises an exception.
