How to overlay an image on camera view for iPhone? [duplicate]

This question already has an answer here: Ios creating simple camera overlay in Xcode how? (1 answer) Closed 5 years ago.

I am new to iphone developme开发者_JAVA技巧nt, and I want to make an application that will use the camera view as the background. Then I would like to put certain image overlays over the camera view. How would I go about doing this?

Use cameraOverlayView property when using UIImagePickerControllerSourceTypeCamera. This property is not available when using other sourceTypes though.

[picker setCameraOverlayView: someTransparentView];
