I am making an app for the iPad and want to be able to use the iPad 2 camera if available. Is the code to load the iPad camera the same as for the iPhone 4? I have this same code working on the iPhone version of this app, but do not have an iPad 2 to test with and simulator can't help me with the camera. Below is what I have to determine if camera is available and then to load camera or load library in popup
Basically I just need to know if the line below is supported by the iPad 2 camera or do I need to use something else?
[self presentModalViewController:imagePickerController animated:YES];
I want camera to be full screen and not in a popup.
- (IBAction) takePhoto:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setDelegate:self];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera];
imageView.contentMode = UIViewContentModeScaleAspectFit;
[self presentModalViewController:imagePickerController animated:YES];
} else {
imagePickerController = [[UIImagePickerController alloc] init];
[imagePickerController setDelegate:self];
[imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
imageView.contentMode = UIViewContentModeScaleAspectFit;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
[popover setDelegate:self];
[popover presentPopoverFromBarButtonItem:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
}
Yes this works, for sure if self is a UINavigationController. I know this because I do the same in my app. I'm not sure for other UIViewControllers, but it stands to reason that it will also work.

I have read the UIPopoverController docs and more then 10 stackoverflow solutions which none work in iOS 8.0.2 ipad device.
THE GOAL:
I want to present a sharing view which when clicked outside dissmisses.
THE PROBLEM:
The code works fine below iOS 8.0.
THE CODE (tried many versions...):
NSArray *dataToShare = #[url]; // ...or whatever pieces of data you want to share.
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
activityViewController.modalInPopover = YES;
self.act = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
[self.act presentPopoverFromRect:CGRectMake(self.view.bounds.size.width/2, self.view.bounds.size.height/2, self.view.bounds.size.width/2, self.view.bounds.size.width/2) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
self.act.delegate = self;
I have added the :
UIPopoverControllerDelegate
WHAT I HAVE TRIED:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
As soon that the
UIPopoverController
is presented the view losses focus and doesn't register touches. Therefore, I can't handle touches outside the self.act rect space in order to force a dissmisal.
also...
NSArray *dataToShare = #[url]; // ...or whatever pieces of data you want to share.
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
activityViewController.modalInPopover = YES;
UIPopoverPresentationController *presentationController = [activityViewController popoverPresentationController];
presentationController.sourceView = self.view; // if button or change to self.view.
[self.parentViewController presentViewController:activityViewController animated:YES completion:nil];
and I tried to present the UIActivityViewController and UIPopoverController from the parent which didn't work aswell.
Please help, I lost half day on something this stupid which works on iOS 7.1 and not on iOS 8+ which is ridiculous and I still have no clue why.
I will try to add the cancel button which has also disappeared in iOS8+.
UPDATE 1:
Adding a UIButton inside a UIBarButtonItem didn't help...
UIButton *control = (UIButton *) sender;
[control setFrame:CGRectMake(300, 300, 100, 100)];
[control setBackgroundColor:[UIColor redColor]];
UIBarButtonItem *barButtonItemView = [[UIBarButtonItem alloc] init];
[barButtonItemView setCustomView:control];
[self.popup presentPopoverFromBarButtonItem:barButtonItemView permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
UPDATE 2 - 19.12.2014. (iOS 7.1. - 8.1.2):
The accepted answer works on iOS 8.1. I had some errors with iOS 7.1. so I modified it to work for iOS 7.1. I have stated on which devices the code works in the comments below the answer.
// publish - sharing
NSArray *dataToShare = #[url]; // ...or whatever pieces of data you want to share.
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
NSLog(#" SHARING - 1 - ");
[self presentViewController:activityViewController animated:YES completion:^{}];
}
else
{
// Change Rect to position Popover
NSLog(#" SHARING - 2 - ");
self.popup = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
[self.popup presentPopoverFromRect:CGRectMake(self.view.frame.size.width * 3 / 5 ,
self.view.frame.size.width/2,
self.view.frame.size.width/10,
self.view.frame.size.width/10) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
How about just add this.
UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
applicationActivities:nil];
activityViewController.modalInPopover = YES;
activityViewController.popoverPresentationController.sourceView = self.view;
In IOS6 I am using following method to get photo from I Pad photo Library.But now its not working for IOS7
UIImagePickerController* picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerCameraCaptureModePhoto;
picker.delegate = self;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
[popover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
[picker release], picker = nil;
What is issue with IOS7
Here you can use custom Frame and load the popover ;)
[popOver presentPopoverFromRect:CGRectMake(self.view.frame.size.width-50, 50, 10, 10) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Check out UIImagePickerController crash only on iOS 7 - iPad
Its Probably an iOS 7 Bug. Probably your personal hotspot is on at the moment try to turn it off at and run the application
I am using ABPeoplePickerNavigationController for selection of address book contact by user. With this code behind action of a button:
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
picker.view.frame=self.view.frame;
[self presentModalViewController:picker animated:YES];
[picker release];
When this code runs it rotates the Landscape UI to Portrait and eventually dismisses the controller that presents this ABPeoplePickerNavigationController.
I am getting this problem only in iOS 5, iPad 2. It's working fine with iOS 6.
I don't believe in 5.x that landscape is supported for this picker. However, try doing it via a different PresentationStyle. I believe it should then work in landscape, i.e:
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
picker.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:picker animated:YES];
I am try to display full camera in iPad. but it displays very small camera. I am using below this code.
imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate=self;
imagePicker.cameraOverlayView.frame = CGRectMake(0, 0, 1000, 700);
[imagePicker.cameraOverlayView sizeToFit];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
imagePicker.wantsFullScreenLayout = YES;
[imagePicker release];
[popover presentPopoverFromRect:CGRectMake(0,0,400,800)
inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
UIImagePickerController is a UINavigationController. Just show it as a full screen modal view controller instead of in a popover.
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.delegate = self;
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
ipc.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentViewController:ipc animated:YES completion:nil];
You only need to use a popover on the iPad for selecting images from the photo library. But the camera is allowed to be shown full screen without a popover.
When I invoke camera using the UIimagepicker controller it does not show in full screen mode on iPhone with iOS version 4.2, but it does work in iOS 5.
Can anyone tell me the code that needs to be changed and what is the problem with existing code?
I am using the following code:
- (IBAction)takePicture:(id)sender
{
UIImagePickerController* imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.showsCameraControls = YES;
imagePicker.allowsEditing = NO;
imagePicker.toolbarHidden = YES;
imagePicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
imagePicker.wantsFullScreenLayout = YES;
if ([UIImagePickerController respondsToSelector:#selector(isCameraDeviceAvailable:)])
{
if ([UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront])
{
[imagePicker setCameraDevice:UIImagePickerControllerCameraDeviceFront];
}
}
// Show the camera UI and View Finder.
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
}

one of the solution is applying scaling trasnformation - here on stack maybe it will help
I don't see why you are doing these 3 things:
[self.navigationController setNavigationBarHidden:YES];
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
[self.camPicker.view setUserInteractionEnabled:YES];
Or for that matter why you are caching the instance of UIImagePickerController (this may cause significantly higher idle memory usage for your application compared to discarding the image picker controller between uses).
Does it work better if you don't do these things?
