Camera not presenting in ipad running iOS 8.2 - ios

Question

I am working on universal app and want to open camera. Now I am able to open camera with UIimagePickerController on iphone but on iPad its not working. I have searched for solution and found this code
self.cameraController = [[UIImagePickerController alloc] init];
self.cameraController.sourceType = UIImagePickerControllerSourceTypeCamera;
self.cameraController.modalPresentationStyle = UIModalPresentationCurrentContext;
self.cameraController.showsCameraControls = NO;
self.cameraController.navigationBarHidden = YES;
self.cameraController.wantsFullScreenLayout = NO;
[self.cameraController setCameraOverlayView:ar_overlayView];
[ar_overlayView setFrame:self.cameraController.view.bounds];
UIViewController *vc = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
if([[[UIDevice currentDevice] systemVersion] floatValue]>=8.0 && UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
[self presentViewController:self.cameraController animated:YES completion:nil];
}];
}
else{
[vc presentViewController:self.cameraController animated:YES completion:nil];
}
Also followed some tutorial like
TechnoTopia Post but didn't find any luck.I have tested it in iphone 5s and is working fine in it but on iPad mini the camera is not presenting. Any help would be appreciated!

Answer 1

Try This For iPad
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex==0)
{
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
UIImagePickerController* picker=[[UIImagePickerController alloc]init];
picker.delegate=self;
picker.allowsEditing=YES;
picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:nil];
}];
}
else if (buttonIndex==1)
{
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
UIImagePickerController* picker=[[UIImagePickerController alloc]init];
picker.delegate=self;
picker.allowsEditing=YES;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:nil];}];
}
}

For iPad you should do:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
[popover presentPopoverFromRect:self.selectedImageView.bounds inView:self.selectedImageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popOver = popover;
}else {
[self presentModalViewController:picker animated:YES];
}
where in .h file declare:
#property (nonatomic, strong) UIPopoverController *popOver;
You should handle popover delegate:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
Apple docs:
apple link
it states that:
"Present the user interface by calling the presentViewController:animated:completion: method of the currently active view controller, passing your configured image picker controller as the new view controller. 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."

try this code :
UIImagePickerController *aImgPickerController = [[UIImagePickerController alloc] init];
aImgPickerController.delegate = self;
aImgPickerController.allowsEditing = YES;
aImgPickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[self presentViewController:aImgPickerController animated:NO completion:^{
NSLog(#"success present picker");
}];
});

- (IBAction)onClickSelectPicture:(id)sender
{
if( [UIImagePickerController isCameraDeviceAvailable: UIImagePickerControllerCameraDeviceFront ])
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType=UIImagePickerControllerSourceTypeCamera;
picker.cameraDevice=UIImagePickerControllerCameraDeviceFront;
[self presentViewController:picker animated:YES completion:NULL];
}
else
{
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Device has no camera"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[myAlertView show];
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
imgProf = info[UIImagePickerControllerEditedImage];
[viewNewPhoto setImage:imgProf];
imgProf = [self imageWithImage:imgProf scaledToSize:CGSizeMake(imgProf.size.width/4, imgProf.size.height/4)];
if (imgProf == nil)
{
imgPhotoString = #"NoPhoto";
}else
{
imgPhotoString = [self getStringFromImage:imgProf];
}
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissViewControllerAnimated:YES completion:NULL];
}
