Displaying UIImagePickerController within another UIView

Question

I've been working pretty extensively the last couple months with UIImagePickerController, particularly with the new capabilities in OS3.1 and newer to overlay views on-top of the camera view. This has worked just fine.

However, I am currently working on a project where I'd like to be able to display the camera view of the UIImagePickerController within an existing view. Essentially, the exact opposite of what I've currently been doing.

An example would be a View Controller with navigation components (Think top and bottom horizontal bars with gradients), and upon tapping a button on one of these bars, then content area displays the camera view. The shutter animation would should up, and the top and bottom navigation bars would remain always on-top.

I've had success adding the UIImagePickerController to the window view, as well as presenting it modally, but haven't had any luck adding it as a subView.

ex:

[window addSubview:camera.view];
[self presentModalViewController:camera animated:YES];

Answer 1

All you need to do is call viewWillAppear and viewDidAppear.

Here is an example where _pickerController is an instance of UIImagePickerController:

[self.view addSubview:_pickerController.view];
[_pickerController viewWillAppear:YES];
[_pickerController viewDidAppear:YES];

Answer 2

Call viewWillAppear:YES on the image picker controller after adding its view to your view. Skip the modal view controller business.
