/* I worked on this code. The issue is when I try to make multiple shot it shows "Received Memory Warning" and my app got crashed.
In this I tried to count the images,at the same time It counts "Camera not ready mode" also So that my taken images saved multiple times.
How can I solve this issue ? */

Try this,
int counter;
NSMutableArray * imageArray;
-(void)takePicture
{
counter=0;
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setDelegate:self];
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image= [info objectForKey:UIImagePickerControllerEditedImage];
[imageArray addObject:image];
counter++;
if (counter<PhotoCount)
{
[self dismissModalViewControllerAnimated:NO];
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setDelegate:self];
[self presentModalViewController:imagePicker animated:NO];
[imagePicker release];
}
else
{
[self dismissModalViewControllerAnimated:YES];
}
}
PhotoCount is the number of photos you want to take.

Captured image is not getting saved in the device

I have created two options in the screen.
To capture the image from camera using : UIImagePickerControllerSourceTypeCamera
To load the image from the UIImagePickerControllerSourceTypeSavedPhotosAlbum.
But when i am capturing the image, image is not storing in the device?
My code is:
-(void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{
NSLog(#"From didDismissWithButtonIndex - Selected Option: %#", [actionSheet buttonTitleAtIndex:buttonIndex]);
NSString*image=[actionSheet buttonTitleAtIndex:buttonIndex];
if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:#"Camera"]) {
if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:nil message:#"Device Camera Is Not Working" delegate:nil cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[alert show];
return;
}
else{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
}
else if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:#"Gallery"])
{
UIImagePickerController *pickerView = [[UIImagePickerController alloc] init];
pickerView.allowsEditing = YES;
pickerView.delegate = self;
[pickerView setSourceType:UIImagePickerControllerSourceTypeSavedPhotosAlbum];
//[pickerView setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[self presentViewController:pickerView animated:YES completion:nil];
}
}

Just put this line in - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{ to store image
When you capture image you have to store it manually.
UIImageWriteToSavedPhotosAlbum(orginalImage,nil, nil, nil);
Hope this will help you
It's because you're not doing anything with the image. You assign it as b64 string to an array and that's it. You must save it to the camera roll manually:
UIImageWriteToSavedPhotosAlbum(tableIMAGE.image, nil, nil, nil);
You have to save image camera roll in didFinishPickingMediaWithInfo like this
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
if(picker.sourceType==UIImagePickerControllerSourceTypeCamera)
{
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
[PHAssetChangeRequest creationRequestForAssetFromImage:image];
} completionHandler:nil];
}
}

IOS image picker in navigation view controller

I am trying to browse an image and display in imageview using UIImagePickerController. Basically the view I am using to browse the image is based on navigationController.
But using the below code after I select the image and come back to view, I can see that the view is flickering to left right and the image is not showing in image view.
Actually the entire source code is quit long, thats why I post the image picker part only. If required I can post more code.
RegistrationFormViewController.h
#interface RegistrationFormViewController : ViewController
<UIImagePickerControllerDelegate,UINavigationControllerDelegate,CLLocationManagerDelegate>
{
CLLocationManager *locationManager;
UIImagePickerController *imagePickerController;
}
#property (strong, nonatomic) CLLocationManager *locationManager;
#property (weak, nonatomic) IBOutlet UIImageView *imageUser;
- (IBAction)registerBt:(id)sender;
RegistrationFormViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
_barButtonBack.target = self.revealViewController;
_barButtonBack.action = #selector(revealToggle:);
[self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapDetected)];
singleTap.numberOfTapsRequired = 1;
[self.imageUser setUserInteractionEnabled:YES];
[self.imageUser addGestureRecognizer:singleTap];
}
-(void)tapDetected{
NSLog(#"single Tap on imageview");
imagePickerController = [[UIImagePickerController alloc]init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePickerController animated:YES completion:nil];
}
#pragma mark - ImagePickerController Delegate
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
// Dismiss the image selection, hide the picker and
//show the image view with the picked image
[picker dismissViewControllerAnimated:YES completion:nil];
[self.imageUser setImage:image];
self.imageUser.contentMode = UIViewContentModeScaleAspectFill;
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissViewControllerAnimated:YES completion:nil];
}
There is no issue in your code that you showed here. However try this in didFinishPickingImage -
dispatch_async(dispatch_get_main_queue(), ^{
self.imageUser.contentMode = UIViewContentModeScaleAspectFill;
[self.imageUser setImage:image];
});
and move this code to viewDidLoad
imagePickerController = [[UIImagePickerController alloc]init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
you can also check whether you are getting the image or not using breakpoint.
try this delegate method
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerOriginalImage];
[picker dismissViewControllerAnimated:YES completion:NULL];
}
In viewcontroller.m file, just put this code:
#import <AssetsLibrary/AssetsLibrary.h>
typedef void (^ALAssetsLibraryAssetForURLResultBlock)(ALAsset *asset);
typedef void (^ALAssetsLibraryAccessFailureBlock)(NSError *error);
- (IBAction)Gallery:(id)sender {
self.ImagePickerController = [[UIImagePickerController alloc]init];
self.ImagePickerController.delegate = self;
self.ImagePickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentViewController:self.ImagePickerController animated:YES completion:nil];
}
- (IBAction)Camera:(id)sender {
self.ImagePickerController = [[UIImagePickerController alloc]init];
self.ImagePickerController.delegate = self;
self.ImagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:self.ImagePickerController animated:YES completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info
{
[picker dismissViewControllerAnimated:YES completion:nil];
NSURL *imageUrl = (NSURL *)[info objectForKey:UIImagePickerControllerReferenceURL];
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
{
ALAssetRepresentation *representation = [myasset defaultRepresentation];
CGImageRef resolutionRef = [representation fullResolutionImage];
if (resolutionRef) {
UIImage *image = [UIImage imageWithCGImage:resolutionRef scale:1.0f orientation:(UIImageOrientation)representation.orientation];
self.SelectedImage.image =image;
}
};
ALAssetsLibraryAccessFailureBlock failureblock = ^(NSError *myerror)
{
NSLog(#"cant get image - %#",[myerror localizedDescription]);
};
if(imageUrl)
{
ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc]init];
[assetslibrary assetForURL:imageUrl resultBlock:resultblock failureBlock:failureblock];
}
}
In viewcontroller.h file
#interface ViewController : UIViewController<UIImagePickerControllerDelegate,UINavigationControllerDelegate>
#property (nonatomic)UIImagePickerController *ImagePickerController;
#property (weak, nonatomic) IBOutlet UIImageView *SelectedImage;

<Error>: CGImageCreateWithImageProvider: invalid image size: 150 x 150. error in __connection_block_invoke_2: Connection interrupted

When I am running my app on a device (8.0.2) (not the simulator), there are two errors simultaneously.
One is
<Error>: CGImageCreateWithImageProvider: invalid image size: 150 x 150.
Another is
error in __connection_block_invoke_2: Connection interrupted
Here is the code:
- (IBAction)chooseImage:(id)sender {
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
self.actionSheet = [[UIActionSheet alloc] initWithTitle:#"choose picture"
delegate:self
cancelButtonTitle:#"cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"take photos", #"from photo album", nil];
}
else
{
self.actionSheet = [[UIActionSheet alloc] initWithTitle:#"choose picture"
delegate:self
cancelButtonTitle:#"cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"from photo album", nil];
}
self.actionSheet.tag = 1000;
[self.actionSheet showInView:self.view];
}
-(void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (actionSheet.tag == 1000)
{
NSUInteger sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
switch (buttonIndex)
{
case 0:
sourceType = UIImagePickerControllerSourceTypeCamera;
break;
case 1:
sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
break;
case 2:
return;
}
}
else
{

}
}

imagePickerController.sourceType = sourceType;
[self presentViewController:imagePickerController animated:YES completion:^{
}];
}}
#pragma mark - image picker delegte
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:^{}];
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
[self.chooseImage setImage:image forState:UIControlStateNormal];
//self.productImage.image = image;
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:YES completion:^{}];
}
It's a bug in iOS 10.
The Method - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info changes to - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info
Add GCD this way:
[picker dismissViewControllerAnimated:YES completion:^{}];
dispatch_async(dispatch_get_main_queue(), ^{
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
[self.chooseImage setImage:image forState:UIControlStateNormal];
//self.productImage.image = image;
});
}

UIImagePickerController push viewcontroller bug with allowsEditing

I am trying to push a view controller (for extra editing) from UIImagePickerController after user has selected an image.
It is successfully pushed.
But when that view controller is popped and user return to the editing screen, the editing screen is no longer interactable. Does anyone know what is the problem.
-(void)didTapBtn:(id)sender
{
self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
self.picker.delegate = self;
self.picker.allowsEditing = YES;
[self presentViewController:self.picker animated:YES completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
if (image == nil) {
image = [info objectForKey:UIImagePickerControllerOriginalImage];
}
if (image == nil) {
return;
}
self.test = [[BTTestViewController alloc] init];
self.test.delegate = self;
[self.picker pushViewController:self.test animated:YES];
}
//Called by BTTestViewController
-(void)didCancel
{
[self.picker popViewControllerAnimated:YES];
}
try this one it work in my application:
UIImagePickerController *imagePicker;//put it in .h file
put it in .m file
imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"STEP-BY-STEP-STORY!" message: #"Camera is not available" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *pickedImage = [info objectForKey:UIImagePickerControllerEditedImage];
imageData.image =[self resizeImage:imageData.image width:200 height:200];
[picker dismissViewControllerAnimated:YES completion:nil];
iphone_filtersViewController *nav=[[iphone_filtersViewController alloc]initWithNibName:#"iphone_filtersViewController" bundle:nil];
[self.navigationController pushViewController:nav animated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
// release Picker
[picker dismissViewControllerAnimated:YES completion:nil];
}
// iphone_filtersViewController method
-(IBAction)backButton
{
[self.navigationController popViewControllerAnimated:YES];
}
may be it will help.

2 UIButtons to set 2 UIImageViews

I've 2 UIButtons, I want both buttons to pick an image, button1 is setting an image to imageview1 and button2 to imageView2. I now created button1 which picks an image and set imageView1 to that image, but if I'm creating button2, I don't now what I have to do in:
- (IBAction)chooseImage1:(id)sender {
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePicker animated:YES completion:nil];
}
- (IBAction)chooseImage2:(id)sender {
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:imagePicker animated:YES completion:nil];
}
UIImage *image;
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *mediaURL;
mediaURL = (NSURL *)[info valueForKey:UIImagePickerControllerMediaURL];
image = (UIImage *)[info valueForKey:UIImagePickerControllerOriginalImage];
imageView1.image=image;
[picker dismissViewControllerAnimated:YES completion:nil];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:nil];
}
Create an index in your .h file. Something like
NSUInteger *selectedImageIndex;
And in your .m file :
- (void)showImagePicker:(UIImagePickerControllerSourceType)source{
UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
ipc.sourceType = source;
ipc.allowsEditing = YES;
ipc.delegate = self;
[self presentModalViewController:ipc animated:YES];
}
- (IBAction)chooseImage1:(id)sender {
selectedImageIndex = 1;
[self showImagePicker:UIImagePickerControllerSourceTypePhotoLibrary];
}
- (IBAction)chooseImage2:(id)sender {
selectedImageIndex = 2;
[self showImagePicker:UIImagePickerControllerSourceTypePhotoLibrary];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *img = [info objectForKey:#"UIImagePickerControllerEditedImage"];
if (!img)
img = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
if (selectedImageIndex == 1)
imageView1.image=img;
else
imageView2.image = img;
[picker dismissViewControllerAnimated:YES completion:nil];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:nil];
}
But then again, this is just one way to do it.
