Subclassing UIImagePickerController

[hack4]

I'm trying to modify the UI that the user is presented with when they're taking a picture. Specifically, I want to remove the "Take Picture" title bar and replace it with a custom graphic.

I can create a subclass of UIImagePickerController that doesn't change anything, and (from what I can tell) the things I want to change are a higher level than the controller itself.

I'm a little lost on how to start. If anyone could share some thoughts (or even a tiny bit of code) I'd greatly appreciate it.

Thanks

I think I need to do the same thing. I've got an application mostly built, but I need to access the images via the UIImagePickerController and can't seem to figure it out without displaying the UIImagePickerController window, which isn't an option.

Anyone got any ideas?

I don't think apple will allow you to modify their camera controller as they will most likely change the core of it. So a subview that works to change the take picture bar might be different upon a firmware update... Therefore I don't believe it is possible in that apple will not approve the application.

I've been researching this for the past couple days, I think you're right. I've managed to change the view on the UIImagePickerControl, but I havent managed to access the actual photos, so it does me no good.

I found there are some private headers you can load up which will give you access, but same thing Apple wont allow them, so still a no go.

Thanks for confirming.

I just wrote a short article on my blog discussing the view hierarchy in UIImagePickerController - the view hierarchy you want actually belongs to PLCameraController rather than UIImagePickerController. Although that controller is undocumented, you don't need to use undocumented APIs to manipulate its views.
