How to find out if the iOS camera is working and not being adjusted

Question

We are creating an application in which we need to show one of the following states:

• focused
• focusing (adjustment),
• not focused.

It seems that when you move the camera, the camera will not try to adjust until you stop moving. So how to determine this condition?

Answer 1

You can use the adjustingFocus property of AVCaptureDevice to accomplish what you mentioned. More information on this can be found here .
