Save UIImage, Load it in Wrong Orientation
The root cause is PNG format doesn’t have image orientation information, but JPEG format does. So the easiest way to solve this problem is saving your file in JPEG format using UIImageJPEGRepresentation()

Why has `android:screenOrientation=”behind”` no effect in android 4.1.2?
android:targetSdkVersion=”16″ Remove this statement in your manifest file, because SDKVersion=16 is only available for v4.0.
Images taken with ACTION_IMAGE_CAPTURE always returns 1 for ExifInterface.TAG_ORIENTATION on some Gingerbread devices
Ok guys, it seems like this bug for android won’t be fixed for a while. Although I found a way to implement the ExifInformation so that both devices (ones with proper Exif tag, and also improper exif tags work together).. So the issue is on some (newer) devices, there’s a bug that makes the picture … Read more
Android onConfigurationChanged not being called
This was my gremlin for the ~same problem: Caution: Beginning with Android 3.2 (API level 13), the “screen size” also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion … Read more
Orientation in a UIView added to a UIWindow
You can read about some of the possible causes here: Technical Q&A QA1688 – Why won’t my UIViewController rotate with the device? In your situation its probably the fact that you are adding the view as another subview to the window. Only the first subview gets the rotation events. What you can do is add … Read more
How can I change the scroll direction in UICollectionView?
UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init]; [flowLayout setScrollDirection:UICollectionViewScrollDirectionVertical]; Note too that it seems to be fine to call this in prepareForLayout in your flow layout… @interface LayoutHorizontalThings : UICollectionViewFlowLayout @end @implementation LayoutHorizontalBooks -(void)prepareLayout { [super prepareLayout]; self.scrollDirection = UICollectionViewScrollDirectionHorizontal; self.minimumInteritemSpacing = 0; self.minimumLineSpacing = 0; self.itemSize = CGSizeMake(110,130); self.sectionInset = UIEdgeInsetsMake(0, 0, 0, 0); }
Best way to programmatically detect iPad/iPhone hardware
Checking at runtime (your first way) is completely different from #if at compile time. The preprocessor directives won’t give you a universal app. The preferred way is to use Apple’s Macro: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { // The device is an iPad running iPhone 3.2 or later. } else { // The device is an … Read more
Responsive site is zoomed in when flipping between Portrait and Landscape on iPad/iPhone
You also want to add the maximum scale <meta name=”viewport” content=”width=device-width, initial-scale=1, maximum-scale=1″> UPDATED I agree with some of the comments, the declaration should not limit the scaling by the user as this is bad practice. The below is a better approach and I believe that the zooming bug has long since been fixed by … Read more
Set a border around a StackPanel.
What about this one : <DockPanel Margin=”8″> <Border CornerRadius=”6″ BorderBrush=”Gray” Background=”LightGray” BorderThickness=”2″ DockPanel.Dock=”Top”> <StackPanel Orientation=”Horizontal”> <TextBlock FontSize=”14″ Padding=”0 0 8 0″ HorizontalAlignment=”Center” VerticalAlignment=”Center”>Search:</TextBlock> <TextBox x:Name=”txtSearchTerm” HorizontalAlignment=”Center” VerticalAlignment=”Center” /> <Image Source=”lock.png” Width=”32″ Height=”32″ HorizontalAlignment=”Center” VerticalAlignment=”Center” /> </StackPanel> </Border> <StackPanel Orientation=”Horizontal” DockPanel.Dock=”Bottom” Height=”25″ /> </DockPanel>
Detecting iOS orientation change instantly
Add a notifier in the viewWillAppear function -(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil]; } The orientation change notifies this function – (void)orientationChanged:(NSNotification *)notification{ [self adjustViewsForOrientation:[[UIApplication sharedApplication] statusBarOrientation]]; } which in-turn calls this function where the moviePlayerController frame is orientation is handled – (void) adjustViewsForOrientation:(UIInterfaceOrientation) orientation { switch (orientation) { case UIInterfaceOrientationPortrait: case … Read more
