I use following code to take picture
self.imagePickerController = [[UIImagePickerController alloc] init];
self.imagePickerController.delegate = self;
self.imagePickerController.sourceType = sourceType;
self.imagePickerController.allowsEditing = YES;
self.imagePickerController.showsCameraControls = YES;
self.imagePickerController.wantsFullScreenLayout = YES;
[self presentViewController:self.imagePickerController animated:NO completion:nil];
after taking, it will jump to a preview with two button: retake and use
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
the above class method can't be called until i click the button use, so is there any class method can I use when entering preview view? thanks

I am replacing the part of image by capture image from camera. i need to perform the activity like this app in my application. https://itunes.apple.com/in/app/replace-my-face-funny-girls/id794033892?mt=8
I need a way of how can i take picture from background view with super view image and save the new generated image with merging of both image.
Please suggest me solution.
The simple work i did
- (void)viewDidLoad {
[super viewDidLoad];
self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.picker.delegate = self;
self.picker.allowsEditing = NO;
self.picker.showsCameraControls = NO;
self.picker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
CGRect overlayRect = CGRectMake(0, 0, self.imageView.frame.size.width,self.imageView.frame.size.height);
UIView *overlayView = [[UIView alloc] initWithFrame:overlayRect];
UIImageView *capture_image=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.imageView.frame.size.width,self.imageView.frame.size.height)];
capture_image.image=[UIImage imageNamed:#"1.jpg"];
[overlayView addSubview:capture_image];
[self.picker setCameraOverlayView:overlayView];
[self.navigationController presentViewController:self.picker animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerOriginalImage];
self.imageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Please also suggest me if there is any repository working like this approach.
About capturing the image: you might want to look at FastttCamera, which allows you to set the camera view to your defined image view and crops the image accordingly.
Good luck!
- (void)pickImage {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self;
[self presentViewController:picker animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
_image = (UIImage *)[info objectForKey:UIImagePickerControllerOriginalImage];
[_imageView setImage:_image];
[self.view addSubview:_imageView];
[self dismissViewControllerAnimated:YES completion:^{}];
}
You can't select multiple photos or videos simultaneously
You have to use custom ImagePicker. And I think ELCImagePickerController is the best option in my opinion.
There is also some other library that can be used..
ELCImagePickerController
WSAssetPickerController
QBImagePickerController
ZCImagePickerController
CTAssetsPickerController
AGImagePickerController
I have a problem with iOS ImagePicker. It works correctly, but when I want to take another photo the camera loads for a very long time (first time: 1-2sec, second time and later: 8-10sec). This is how I use it:
- (void)takePhoto {
_imagePicker = [UIImagePickerController new];
_imagePicker.delegate = self;
_imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
_imagePicker.allowsEditing = NO;
[self presentViewController:_imagePicker animated:YES completion:nil];
}
and this is how I get the image:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
[_imagePickerView.imageView setImage:image];
}
I don't see there much place for bugs. Of course I implement protocols UIImagePickerControllerDelegate and UINavigationControllerDelegate.
Do you have any ideas how can I figure out what is causing this?
You may want to dismiss the UIImagePickerController after you picked an item by calling
[_imagePicker dismissViewControllerAnimated:YES completion:nil];
It should be fine, now.
Try changing your first block of code to reuse the same imagePicker you have already initialized:
- (void)takePhoto {
if(_imagePicker == nil)
_imagePicker = [UIImagePickerController new];
_imagePicker.delegate = self;
_imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
_imagePicker.allowsEditing = NO;
[self presentViewController:_imagePicker animated:YES completion:nil];
}
guys.
I'm trying to capture multiple images from the camera in iOS7, when I capture the first image and click in in "Use Photo", then it's store the image in a array in didFinishPickingMediaWithInfo. When the camera appear again, I see the last image in background but I can't see the camera movement. I know the camera is enabled, because it's searching faces. The code is below:
- (IBAction)openTour:(id)sender
{
_counter=0;
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.showsCameraControls = YES;
imagePicker.delegate = self;
[self presentViewController:imagePicker animated:YES completion:nil];
imagePicker = nil;
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo: (NSDictionary *)info
{
UIImage *image= [info objectForKey:UIImagePickerControllerEditedImage];
[ _imageArray addObject:image ];
_counter++;
if ( _counter<5 )
{
[self dismissViewControllerAnimated:NO completion:nil];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.showsCameraControls = YES;
imagePicker.delegate = self;
[self presentViewController:imagePicker animated:NO completion:nil];
imagePicker = nil;
}
}
else
{
[self dismissViewControllerAnimated:YES completion:nil];
}
}
Does anyone know what is happening?
Thanks in advance!
Set showsCameraControls = NO;
Use cameraOverlayView property.
In the action of your camera button call takePicture method.
Keep adding UIImage objects received by the method
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
I have a UIPickerController that gets your pictures and allows you to pick some of them though at the moment when I click the button to activate it the app crashes.
Here is the code that I am using for it:
in my ViewDidLoad method:
pickerController = [[UIImagePickerController alloc] init];
pickerController.allowsEditing = NO;
pickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
The function:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissViewControllerAnimated:YES completion:nil];
patientPicture = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
UIImageView *pictureView = (UIImageView *)[imageCell viewWithTag:777];
pictureView.image = patientPicture;
[_imgViewAdd reloadInputViews];
}
And it being called:
- (IBAction)addPicture:(id)sender {
[self presentViewController:pickerController animated:YES completion:nil];
}
It is wierd because I have recently changed my app to Ipad only though while it was in IPhone it worked fine. When you click the button in NSLog this error message crops up which I supose is something to do with it:
UIStatusBarStyleBlackTranslucent is not available on this device.
I suspect this is quite a common issue that people have
Thanks in advance
Try presenting in a popover...
pickerController = [[UIImagePickerController alloc] init];
UIPopoverController *popOverController = [[UIPopoverController alloc] initWithContentViewController:pickerController];
popOverController.delegate = self;
and to present...
[popOverController presentPopoverFromRect:yourframe inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
