A
UIImageView
displays an image according to its
contentMode
property. This
property determines where to position and how to resize the content within its frame.
UIImageView
's default value for
contentMode
is
UIViewCon-
tentModeScaleToFill
, which will adjust the image to exactly match the bounds of
the image view. If you keep the default, the image taken by the camera will be contorted
to fit into the square
UIImageView
. You have to change the
contentMode
of the im-
age view so that it resizes the image with the same aspect ratio.
Select the
UIImageView
and open the attributes inspector. Find the
Mode
attribute and
change it to
Aspect Fit
, as shown in
Figure 12.3
. This will resize the image to fit within
the bounds of the
UIImageView
.

Now, Option-click
DetailViewController.h
in the project navigator to open it in
the assistant editor. Control-drag from the
UIImageView
to the instance variable area in
DetailViewController.h
. Name the outlet
imageView
and choose
Weak
as the
storage type. Click
Connect
.
DetailViewController
's instance variable area should now look like this:
@interface DetailViewController : UIViewController
{
__weak IBOutlet UITextField *nameField;
__weak IBOutlet UITextField *serialNumberField;
__weak IBOutlet UITextField *valueField;
__weak IBOutlet UILabel *dateLabel;
__weak IBOutlet UIImageView *imageView;
}
