    <p>I created a <strong>custom camera overlay</strong> for the live screen camera view and have imported my own custom icons for the camera, flash and flip buttons. Everything looks good in portrait mode, but when I switch the live camera screen to landscape mode, the orientation of the camera stays in portrait mode and shows this in console,</p> <p><strong>"Error: CGAffineTransformInvert: singular matrix"</strong></p> <p>I tried using the <strong>auto resizing mask</strong>, also have tried setting two different frames for the icons in both portrait and landscape mode in <strong>didRotateFromInterfaceOrientation</strong> method. But none of these are working. </p> <p>My question is, will the landscape orientation support only the default iPhone camera overlay view or will it also support the custom overlayview.</p> <p>Here are the screenshots indicating the behaviour of the icons repositioning each other when switched from portrait to landscape mode. I want exactly like this in my custom overlay view. </p> <p><strong>Edit:</strong></p> <p>I've made the live screen of my custom camera overlay to change by using the <strong>UIDevice Orientation</strong> method. But right now, the frame is not resizing when i try to switch from the portrait to landscape mode. So, i just want the entire frame to resize in landscape mode. Also, in this piece of code, if i try to change the value of <strong>CAMERA_TRANSFORM_Y</strong>, </p> <pre><code>#define CAMERA_TRANSFORM_X 1 #define CAMERA_TRANSFORM_Y 1.234 self.picker.cameraViewTransform = CGAffineTransformScale(self.picker.cameraViewTransform, CAMERA_TRANSFORM_X, CAMERA_TRANSFORM_Y); </code></pre> <p>the size of the overlay view reduces both from the top and bottom margin. But, more size gets reduced from the bottom than from the top margin. I want the overlay size to change uniformly both from the top and from the bottom margin.</p> <p>This is my sample code,</p> <p><a href="https://www.dropbox.com/s/eha3snfnrjamdzo/CustomCamera.zip" rel="nofollow noreferrer">Sample project</a></p> <p><img src="https://i.stack.imgur.com/chhqs.jpg" alt="Landscape mode"></p> <p><img src="https://i.stack.imgur.com/Bq9MM.jpg" alt="Potrait mode"></p>
