如何将后置摄像头实时视频提要显示到UIImageView？

Question

I have been messing around with the AVFoundation framework for iPhone, but I can't seem to be able to get the information from the back video camera to display on an UIImageView I have in interface builder.

This is a single view application.

I just want to get what the back camera sees displayed on an UIImageView.

Thank you!

Answer 1

You don't need a UIImageView, just a UIView.

Take a look at AVCaptureSession and AVCaptureDeviceInput in AVFoundation. With these you can access the cameras.

AVCaptureVideoPreviewLayer can be used to draw the camera input to a UIView.
