    <p>I have been writing an app for iOS, and I am trying to implement landscape views. I am trying to support both iOS 5 and iOS 6, so I have autolayout disabled. When I rotate to landscape, the layout loades correctly. Then I rotate to landscape, and when I rotate back to portrait, the UIImageView containing my logo stretches underneath my button and another label.</p> <p>From ViewController.m:</p> <pre><code>@interface ViewController () - (IBAction)showMenu:(id)sender; @end @implementation ViewController @synthesize start, menuButton, vector_status, login_status, items, recordLength, countdown, change_name, iapi, running, timeOver, setupDone, dfm, motionmanager, locationManager, recordDataTimer, timer, testLength, expNum, sampleInterval, sessionName,geoCoder,city,country,address,dataToBeJSONed,elapsedTime,recordingRate, experiment,firstName,lastInitial,userName,useDev,passWord,session_num,managedObjectContext,dataSaver,x,y,z,mag,image ;

    1. COCheck that UIImageView's autoresizingMask property or via Interface Builder.

    2. COWhen I set that, the image disappears entirely. Before, it was there, but the UIImageView was stretched.

    3. COi mean you have to un-set wrong autoResizingMask settings. Check for UIViewAutoresizingFlexibleHeight first.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
