Where I Put this line in my above codes;
[picker setShowsCameraControls:FALSE];
please help me so that i can change the real view of iPhone camera according to my view which i have designed
Did you try to put it where you create and setup your image picker, i.e. in pickAndDecodeFromSource method?

I am developing an app in which i need to keep open full screen camera open and also add a button on it(bottom right). I googled but couldn't find any healthy solution. Thanks in advance. Have a good day.
Edited
- (void) showCameraUI {
[self startCameraControllerFromViewController: self
usingDelegate: self];
}
- (BOOL) startCameraControllerFromViewController: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
NSLog(#"Start Camera Controller method...");
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
// Displays a control that allows the user to choose picture or
// movie capture, if both are available:
cameraUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeCamera];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
cameraUI.allowsEditing = NO;
cameraUI.delegate = delegate;
[controller presentModalViewController: cameraUI animated: YES];
return YES;
}
P.S: I also added UINavigationControllerDelegate,UIImagePickerControllerDelegate as protocol in header file, but its not still opening camera and show me default view of project.
you can simply capture image Using camera like bellow, i am using this bellow method in my code:-
-(void)btnCemeraOpen
{
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[self dismissModalViewControllerAnimated:YES];
yourImageView.image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
if(yourImageView==nil)
{
}
else
{
//DO logic
}
return;
}
-(void)viewDidLoad
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.showsCameraControls = NO;
[self.view addSubview:imagePicker.view];
}
else
{
// UIAlertView…
}
}
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
imagePicker.delegate = self;
[self presentViewController:imagePicker animated:NO completion:NO];
}
I want to put out an alert when you do not have a camera.
IPhone app launch and move in this code.
But, Crash (This Error >
return UIApplicationMain(argc, argv, nil, NSStringFromClass([CameraAppDelegate class])); > Thread 1: signal SIGABRT) when run in a simulator.
Why is this?
use this code and add UIImagePickerControllerDelegate delegate in .h file
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController* picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
picker.wantsFullScreenLayout = YES;
[self presentModalViewController:picker animated:YES];
}
else
{
UIAlertView *altnot=[[UIAlertView alloc]initWithTitle:#"Camera Not Available" message:#"Camera Not Available" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
altnot.tag=103;
[altnot show];
[altnot release];
}
Create NSObject Class and name it like ClsGlobal, or the name you want..
then write +(BOOL)isCameraDeviceAvailable in your ClsGlobal.h and implement below function in ClsGlobal.m.
+(BOOL)isCameraDeviceAvailable
{
BOOL isCameraAvailable=NO;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
if([UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront] || [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear])
isCameraAvailable = YES;
}
return isCameraAvailable;
}
Use this class method, It will return YES if camera available else return NO.
Now you can call this method using [ClsGlobal isCameraDeviceAvailable]; means your if Condition looks like if([ClsGlobal isCameraDeviceAvailable]).
This method will help you throughout your project in any controller, You have to just import ClsGlobal like #import "ClsGlobal.h".
I have a universal app in Xcode. If the user is using an iPad the use image from library button works great. However if they use an iPhone the button doesn't work.
Here is the error I receive.
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIPopoverController initWithContentViewController:] called when not running under UIUserInterfaceIdiomPad.'
Was told this code would work. Does it go into the (IBAction) Code below?
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { Add Popover code here } else {
Add alternative for popover here }
- (IBAction) useCameraRoll: (id)sender
{
if ([self.popoverController isPopoverVisible]) {
[self.popoverController dismissPopoverAnimated:YES];
} else {
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum])
{
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = YES;
newMedia = NO;
}
}
}
This crash is occuring because you can't use UIPopOverControllers on iPhones, only on iPads.
[UIPopoverController initWithContentViewController:] called when not
running under UIUserInterfaceIdiom Pad.'
Try something like this:
- (IBAction)useCameraRoll:(id)sender
{
UIPopoverController *popoverController = [[UIPopoverController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum])
{
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = YES;
newMedia = NO;
}
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
if (popoverController.isPopoverVisible) {
[popoverController dismissPopoverAnimated:YES];
}else{
[popoverController setContentViewController:imagePicker];
[popoverController setDelegate:self];
[popoverController presentPopoverFromRect:CGRectMake(0, 0, 320, 320) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}else{
[imagePicker presentViewController:imagePicker animated:YES completion:nil];
}
}
I'm trying to write code to select an image from the photo library on an iPad. The code that I'm using is below (taken from Apple's website), but it keeps giving me an error saying that On iPad, UIImagePickerController must be presented via UIPopoverController. I've tried changing this line: UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init]; to use a UIPopoverController, but obviously I'm doing something wrong because its not working.
- (BOOL) selectImage: (UIViewController*) controller
usingDelegate: (id <UIImagePickerControllerDelegate,
UINavigationControllerDelegate>) delegate {
if (([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO)
|| (delegate == nil)
|| (controller == nil))
return NO;
UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
mediaUI.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
// Displays saved pictures and movies, if both are available, from the
// Camera Roll album.
mediaUI.mediaTypes =
[UIImagePickerController availableMediaTypesForSourceType:
UIImagePickerControllerSourceTypeSavedPhotosAlbum];
// Hides the controls for moving & scaling pictures, or for
// trimming movies. To instead show the controls, use YES.
mediaUI.allowsEditing = NO;
mediaUI.delegate = delegate;
[controller presentModalViewController: mediaUI animated: YES];
return YES; }
The Apple Developer page also says: "On iPad, you can alternatively present the browser interface using a popover as described in initWithContentViewController: and “Presenting and Dismissing the Popover” in UIPopoverController Class Reference." I've read it but I still can't get it to work. Any help would be appreciated.
Something like this should work:
// create an image picker controller
UIImagePickerController *imagePickerController = [[[UIImagePickerController alloc] init] autorelease];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
imagePickerController.delegate = self;
// present it in a popover
self.popoverController = [[[UIPopoverController alloc] initWithContentViewController:imagePickerController] autorelease];
self.popoverController.delegate = self;
// I was presenting the popover from a button, but you would set the rect to whatever is appropriate for your app
[self.popoverController presentPopoverFromRect:((UIButton *)sender).bounds inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
Declare an ivar such as:
UIPopoverController *imagePopover;
Then:
imagePopover = [[UIPopoverController alloc] initWithContentViewController:mediaUI];
[imagePopover setDelegate:self];
[imagePopover presentPopoverFromRect:someRect
inView:someView
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
in place of
[controller presentModal...];
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 went through a lot of pain coming up with a solution which works on both iPad and iPhone, this is the final code which some of it comes from comments of other people:
the code has some bugs but it's a very good place to start :)
it covers permissions needed as well as how to manage viewcontrollers popoing up on ipad.
requires following imports :
#import <AVFoundation/AVFoundation.h>
#import <AssetsLibrary/AssetsLibrary.h>
and add this delegates :
UIActionSheetDelegate, UIImagePickerControllerDelegate
definitions :
__weak IBOutlet UIButton *attachButton;
UIImage *image;
button's action :
- (IBAction)doAttach:(id)sender {
UIActionSheet *action = [[UIActionSheet alloc] initWithTitle:#"Select image from" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"From library",#"From camera", nil] ;

Is it possible to open webview during use of camera in app.if it is possible plz let me know.
You could try:
- (BOOL)startCameraPickerFromViewController:(UIViewController*)controller usingDelegate:(id<UIImagePickerControllerDelegate>)delegateObject
{
//NSLog(#"008 ::Create Postcard :: start photo camera");
if ((![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) || (delegateObject == nil) || (controller == nil)) {
return NO;
}
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.delegate = self;
UIView *overlay = [[UIView alloc]initWithFrame:CGRectMake(x, y, w, h)];
// overlay.transform = CGAffineTransformMakeRotation(M_PI / 2.0);
// overlay.backgroundColor = [UIColor redColor];
{create your webview here}
[overlay addSubview:webview];
[webview release];
[picker.cameraOverlayView = overlay;
[controller presentModalViewController:picker animated:YES];
return YES;
}
If you have enough recources on the phone it might could work i guess
