Hi All,
I have a UIImagePicker based app that controls the camera with custom overlays to handle a heads up display as well as digital zooming.
I would like to add "touch to adjust exposure" like the normal iPhone camera app has. When you zoom in, you ultimately want to change exposure based on something other than "the big picture view".
UIImagePicker seems to have no tools for doing this... it's all automatic. If I use my custom overlay, the touch events are disregarded by the UIImagePicker.
I've attempted to subclass the UIImagePicker and pass my touch events to Super after they come along... no luck.
I'm currently looking at the AVFoundation framework as it's AVCaptureSession supports setting exposure based on a point. I could toss my existing code and replace it with these tools, but before I do that I thought I'd ask if I was missing a simpler option.
Yes, I know about the WWDC's tutorials on AVFoundation. I'll go that route if tweaking UIImagePicker is out of the question.
