Camera is not working in IOS

I have implemented the following and camera is opened but app is crashed and sometime when open and take the pictures then app is crasshed and log only show "Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates Received memory warning."
The same functionality I have used for take the image from gallery and its working.
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex: (NSInteger)buttonIndex{
if (buttonIndex==0) {
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Alert"
message:#"Device has no Camera!"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[myAlertView show];
}else{
[self performSelector:#selector(loadCamera) withObject:nil afterDelay:1.0];
}
}
}
-(void)loadCamera{
picker1 = [[UIImagePickerController alloc] init];
picker1.delegate = self;
picker1.allowsEditing=YES;
picker1.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker1 animated:YES completion:NULL];
}
Can anyone help.
Solved it by following code:
-(void)loadCamera{
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
dispatch_async(dispatch_get_main_queue(), ^{
picker1 = [[UIImagePickerController alloc] init];
picker1.delegate = self;
picker1.allowsEditing=YES;
picker1.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker1 animated:YES completion: nil];
});
}
}
This code worked for me with iOS 9.2 and xCode 7.2
- (IBAction)takeAPhoto:(VSButton *)sender {
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Device has no camera"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[myAlertView show];
}else {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
}
[self performSelector:#selector(loadCamera) withObject:nil afterDelay:1.0];
-(void)loadCamera
{
if ([UIIagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera)
{
picker1 = [[UIImagePickerController alloc] init];
picker1.delegate = self;
picker1.allowsEditing=YES;
picker1.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker1 animated:YES completion:NULL];
}
}

Camera show black screen in ios 8

This code for capturing image one by one from camera,but after taking one image next time camera will open but with black screen(like it,s shutter close).all other ios version its working,but not working in ios 8.please tell me how can i solve it?
-(void)openCamera
{
if(![PickerHandler doesDeviceSupportMediaType:ITEM_TYPE_PHOTO])
{
[PickerHandler showNoDeviceSupportWarningForMediaType:ITEM_TYPE_PHOTO withDelegate:self];
}
else
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeImage];
[self presentViewController:picker animated:YES completion:nil];
}
}
Go to Settings > Privacy > Pictures ... and check if your app have permission.
In the code, use this to verify camera access.
- (BOOL)authorizedCameraAccess
{
AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
return (status == AVAuthorizationStatusAuthorized);
}
this code is not work in simulator.
UIImagePickerController *videoScreen = [[UIImagePickerController alloc] init];
videoScreen.sourceType = UIImagePickerControllerSourceTypeCamera;
videoScreen.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
videoScreen.allowsEditing = NO;
videoScreen.delegate = self;
[self presentViewController:videoScreen animated: YES completion:NO];
Implement This method
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissViewControllerAnimated:NO completion:NO];
}

UIImagePickerController with UIImagePickerControllerSourceTypeCamera crash EXC_BAD_ACCESS in ios7

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:nil];
This code make crash EXC_BAD_ACCESS on ios7 devices.
On iOS6 - all okay, and UIImagePickerControllerSourceTypePhotoLibrary work normal.
To work with camera
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera]) {
UIImagePickerController* imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
(NSString *) kUTTypeMovie, nil];
[self presentViewController:imagePickerController animated:YES completion:nil]; }

How to use the allowsEditing

I just want the user to take a photo in app→crop→save. So I would want to use the allowsEditing property of UIImagePickerControl. However I don't know how i can do it. this is my code until now for camera.
-(IBAction)TakePhoto {
picker = [[UIImagePickerController alloc]init];
picker.delegate = self;
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
[self presentViewController:picker animated:YES completion:NULL];
}
Use this for pick photo from camera
- (IBAction)takePhoto:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
use this for pick photo from photo library
- (IBAction)selectPhoto:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
use following two delegate methods
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.imageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Add this in your ViewDidLoad method, so if your device is not support camera then display this alert message.
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Device has no camera"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[myAlertView show];
}
Add both protocols to the AppViewController.h file:
#interface APPViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>

Use the UIImagePickerController on a iphone simulator

I have the method, that take photos from gallery or from the camera
-(IBAction) getPhoto:(id) sender {
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if((UIButton *) sender == choosePhotoBtn) {
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
} else {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
[self presentModalViewController:picker animated:YES];
}
But when i run it on the simulator, code doesnt work. And it doesnt work in picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum and picker.sourceType = UIImagePickerControllerSourceTypeCamera
Is the problem in the simulator or in the code?
Try this,
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
else
{
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
}
[self.navigationController presentModalViewController:picker animated:NO];
If you are creating the app for iPad. You will have to present the gallery in a popOver control.
Swift 3/4/5 verison:
if UIImagePickerController.isSourceTypeAvailable(.camera) {
picker.sourceType = .camera
}
else {
picker.sourceType = .savedPhotosAlbum // or .photoLibrary
}
Swift 2 version:
if UIImagePickerController.isSourceTypeAvailable(.Camera) {
picker.sourceType = .Camera
}
else {
picker.sourceType = .SavedPhotosAlbum // or .PhotoLibrary
}
In simulator, you can't use cameraCaptureMode and showsCameraControls.
In simulator your picker.sourceType = UIImagePickerControllerSourceTypeCamera wont be called as there is no camera available in simulator. Also its a good practice to check whether the source type is available to avoid crashes.
#import <MobileCoreServices/UTCoreTypes.h>
….
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePickerCamera =[[UIImagePickerController alloc] init];
imagePickerCamera.delegate = self;
imagePickerCamera.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
imagePickerCamera.allowsEditing = YES;
imagePickerCamera.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:imagePickerCamera animated:YES completion:nil];
}
else if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum])
{
UIImagePickerController *imagePickerAlbum =[[UIImagePickerController alloc] init];
imagePickerAlbum.delegate = self;
imagePickerAlbum.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
imagePickerAlbum.allowsEditing = YES;
imagePickerAlbum.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePickerAlbum animated:YES completion:nil];
}
Similarly to the above answers, but I found this easier. Show a pop up alert if the device doesn't have a camera (like the simulator). Sam code, different usage:
//button if to take a photo
- (IBAction)takePhoto:(id)sender {
//checks if device has a camera
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
UIAlertView *noCameraAlert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"You don't have a camera for this device" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
//shows above alert if there's no camera
[noCameraAlert show];
}
//otherwise, show a modal for taking a photo
else {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:imagePicker animated:YES completion:NULL];
}
}
