Question

Is it possible to dim the light of iPhone's camera flash light programmatically?

Please let me know.

Answer 1

iOS5 will help you with this. It is still under NDA. I suggest you look in the beta documentation for AVCaptureDevice or ask on the Apple developer forum.

It is not possible in iOS4.3.

When the NDA is lifted I will edit this response to give the documentation link.

EDIT

Sorry, it looks like Apple removed the ability to change the torch level in the public release of iOS5. The torchLevel property of AVCaptureDevice is now read-only.

Answer 2

As of iOS 6.0, there is a new call, setTorchModeOnWithLevel, which allows you to set the torch level.

- (BOOL)setTorchModeOnWithLevel:(float)torchLevel error:(NSError **)outError
