I am showing the camera in a popover (on an iPad - the iPad app is locked to Lanscape Left) and the preview is in Portrait and the wrong scale. The code is below - I have worked out the rotation and added it, but the preview size is the too thin now.
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.videoQuality = UIImagePickerControllerQualityTypeMedium;
imagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
CGAffineTransform transformRotation = CGAffineTransformMakeRotation(270 * M_PI/180);
imagePicker.cameraViewTransform = transformRotation;
}
else
{
NSLog(#"Camera not available. Using photo library");
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
imagePicker.delegate = self;
_photoPopover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[_photoPopover presentPopoverFromRect:view.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
Turns out to be an issue with the way iOS 6.0 deals with rotation - its fixed in 6.1
I think this is the solution for ur question so u can follow the code as per this link provided below.
UIImagePickerController in Landscape
It will helps u a lot.Enjoy the coding.

I have an iPhone app that presents a UIImagePickerController for users to take a photo. It works fine on iPhone, iPod and an iPad mini, but on one iPad 3 it comes up like this.
Can anyone think of a reason this would happen? There's nothing blocking the lens, and all other camera apps work fine on the device.
I'm presenting the controller like this:
self.picker = [[UIImagePickerController alloc] init];
self.picker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeImage];
self.picker.delegate = self;
self.picker.toolbarHidden = YES;
self.picker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.picker.allowsEditing = NO;
self.picker.showsCameraControls = YES;
if ([UIImagePickerController isFlashAvailableForCameraDevice:UIImagePickerControllerCameraDeviceRear])
{
self.picker.cameraFlashMode = UIImagePickerControllerCameraFlashModeAuto;
}
[self presentModalViewController:picker animated:YES];
I would really appreciate any help
Thanks
It's an iPhone app running in iPad in iOS7. In iPhone it works fine.
However in iPad, the rotate button is not displayed and the view is like cut off on the top.
I'm not doing anything strange with the image picker. Here's how I show it:
- (void)showImagePickerWithSourceType:(UIImagePickerControllerSourceType)sourceType
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.mediaTypes = #[(NSString*)kUTTypeImage];
imagePicker.sourceType = sourceType;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
//Select front facing camera if available
if (sourceType == UIImagePickerControllerSourceTypeCamera && [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront])
{
imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
}
[self presentViewController:imagePicker animated:YES completion:nil];
}
I have seen other posts on this subject, but no valid solutions. Surely this is possible! I found one solution here that suggests presenting it from a container view controller. The code for that is commented out in my method below. This DOES create the fullscreen view, but the cancel/take photo buttons won't work then, and I can't seem to dismiss it properly. Is there really no simple elegant solution to this???? Please help! Here's my code:
-(IBAction)launchCamera:(id)sender
{
[self.popoverController dismissPopoverAnimated:YES];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
//fullScreenViewController = [[UIViewController alloc] init];
//fullScreenViewController.contentSizeForViewInPopover = CGSizeMake(768, 1024);
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
// Tried making the view full screen (or at least larger), but doesn't work...
//popoverController.contentViewController.contentSizeForViewInPopover = CGSizeMake(384, 512);
[imagePicker setTitle:#"camera"];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeImage];
imagePicker.delegate = self;
imagePicker.allowsEditing = NO;
//[fullScreenViewController.view addSubview:imagePicker.view];
// change imagePicker to fullScreenViewController here for full screen:
popoverController = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[popoverController setDelegate:self];
[popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
I never could make the UIImagePicker work properly in full-screen, so I ended up using the AVFoundation framework to implement my own.
I am testing ipad camera application with ipad simulator
I used below code, change the source type instead of camera.
-(IBAction)useCamera:(id)sender{
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]){
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate =(id<UINavigationControllerDelegate,UIImagePickerControllerDelegate>) self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
newMedia = YES;
}
}
When it run in the simulator error came up in ios 5 simulator .
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:'On iPad, UIImagePickerController must be presented via UIPopoverController'
But its working on 4.3 simulator
Starting with iOS5 you need to show the pickercontroller in a popover view rather than a modal view.
From the apple documentation: On iPad, present the user interface using a popover. Doing so is valid only if the sourceType property of the image picker controller is set to UIImagePickerControllerSourceTypeCamera. To use a popover controller, use the methods described in “Presenting and Dismissing the Popover” in UIPopoverController Class Reference.
http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImagePickerController_Class/UIImagePickerController/UIImagePickerController.html
Here is an example of presenting a UIImagePickerController inside a popover view:
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
[popover presentPopoverFromRect:CGRectMake(0.0, 0.0, 400.0, 400.0)
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
I am facing a problem when I try to access the photo library when developing iPad apps. However, the same code works properly for iPhone dev. The error which is generated is:
On iPad, UIImagePickerController must be presented via UIPopoverController
I am using the following code for iPad development:
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:picker animated:YES];
[picker release];
}
Try presenting with a pop over controller in iPad, doesn't support modal view controller
even I encountered the same problem, so tried using pop over controller and it works now :)
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
popControl = [[UIPopoverController alloc]initWithContentViewController:picker];
popControl.delegate=self;
[popControl presentPopoverFromRect:browseButton.bounds inView:mainView permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
