You can build and run the application now. Select a
BNRItem
to see its details and then
tap the camera button on the
UIToolbar
.
UIImagePickerController
's interface
will appear on the screen (
Figure 12.9
)
, and you can take a picture (or choose an existing
image if you don't have a camera). Tapping the
Use Photo
button dismisses the
UIImagePickerController
.
(If you are working on the simulator, there won't be any images available. However, you
can open
Safari
in the simulator, navigate to a page with an image, and click and hold on
that image. When the action sheet appears, choose
Save Image
. This image will be saved
in the simulator's photo library. But, the simulator can be flaky, so you might have to try a
few different images before one actually saves.)
