I use UIImagePickerController on a subview (280x240). I use this code:
imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setVideoQuality:UIImagePickerControllerQualityType640x480];
[imagePicker setDelegate:self];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setCameraFlashMode:UIImagePickerControllerCameraFlashModeAuto];
[imagePicker setShowsCameraControls:NO];
[imagePicker viewWillAppear:YES]; // trickery to make it show
[imagePicker viewDidAppear:YES];
[self.borderView addSubview:imagePicker.view]; //borderView size is 280x240
I am taking image picker original image and I want to take only displayed area on subview (borderView). How can I do?
try this.
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker = [[MyImagePickerController alloc]init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
imagePicker.showsCameraControls=YES;
[self presentViewController:imagePicker animated:YES completion:^{
NSLog(#"Completed");
}];
and then call delegate method of UIImagePickerController
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
capturedPicImageView.image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
[capturedPicImageView sizeToFit];
capturedPicImageView.contentMode = UIViewContentModeScaleAspectFill;
capturedPicImageView.image = [self resizeAndStoreImages:capturedPicImageView.image];
UIImageWriteToSavedPhotosAlbum(capturedPicImageView.image, nil, nil, nil);
}

I have two image views. When I click a button (e.g. takePhoto) underneath of the 1st image view, the photo taken appears in the first image view. However, when I tap the second "takephotoTwo" button, I want the second photo taken to appear in the second image view (imageTwo). Right now, if I take a photo using the second "takephotoTwo" button, the final (same) image appears in both image views. See code below - does anyone know how I can fix this? I hope I explained this well enough.
E.g.
The photo taken with takePhoto (button) should appear in imageView, and the photo taken with takephotoTwo (button) should appear in imageTwo.
ViewController.m
- (IBAction)selectPhoto:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)takePhoto:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)takePhotoTwo:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)selectPhotoTwo:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *secondImage = info[UIImagePickerControllerEditedImage];
self.imageTwo.image = secondImage;
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.imageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
This is easily achieved by keeping track of which button was tapped or storing a reference to the proper image view based on which button was tapped. Then in the image picker delegate method you set the appropriate image view.
Add an instance variable of type UIImageView * named selectedImageView.
Then update the rest of your code as follows:
- (IBAction)selectPhoto:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
selectedImageView = self.imageView; // Add this
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)takePhoto:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
selectedImageView = self.imageView; // Add this
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)takePhotoTwo:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
selectedImageView = self.imageTwo; // Add this
[self presentViewController:picker animated:YES completion:NULL];
}
- (IBAction)selectPhotoTwo:(id)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
selectedImageView = self.imageTwo; // Add this
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *image = info[UIImagePickerControllerEditedImage];
selectedImageView.image = image;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
The problem is that no matter which button is tapped, you are giving your UIImagePickerController the same delegate. Therefore the same imagePickerController:didFinishPickingMediaWithInfo: is called. But at that point you have no way of knowing which button was tapped, so you have no way of knowing what image view to put the picture into.
Either give the UIImagePickerController a different delegate for each different button, or store in an instance variable somewhere some information about which button was tapped, so that imagePickerController:didFinishPickingMediaWithInfo: can decide correctly what to do.
In iOS 8, When i click to open the camera from my ipad mini it gives warning
"Snapshotting a view that has not been rendered results in an empty snapshot"
I am using the below code to open camera from my device.
- (IBAction)takePhotograph:(UIButton *)sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:NULL];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
[self.cmdTakePhotograph setImage:chosenImage forState:UIControlStateNormal];
[picker dismissViewControllerAnimated:YES completion:NULL];
imageTaken = 1;
Compress = 1;
self.lblErrMsg.hidden = YES;
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Please suggest me solution to remove this warning.
Hope this helps you.
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setDelegate:self];
if ([self respondsToSelector:#selector(presentViewController:animated:completion:)])
{
[imagePicker setShowsCameraControls:NO];
[self presentViewController:imagePicker animated:YES completion:^{
[imagePicker setShowsCameraControls:YES];
}];
}
else
{
[imagePicker setShowsCameraControls:YES];
[self presentModalViewController:imagePicker animated:YES];
}
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init] ;
[imagePicker setAllowsEditing:YES] ;
[imagePicker setDelegate:self] ;
[imagePicker setMediaTypes:[NSArray arrayWithObjects:(NSString *)kUTTypeImage, nil]] ;
[imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary] ;
[self presentViewController:imagePicker animated:YES completion:nil] ;
Step 1: Add Delegate
#interface APPViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
Step 2: Initialize UIImagePicker on click button Action
- (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];
}
Step 3:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.imageView.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Step 4: Dismiss controller
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissViewControllerAnimated:YES completion:NULL];
}
Note: Post your Question with detail description
You are using UIImagePickerController as a variable not as an attribute or property, it means that it will be released at the end of your function. Set your UIImagePickerController as an attribute or property and then the delegate will work.
If you are using a UIPopoverPresentationController, make sure you dismiss the popover before presenting the imagePicker. Otherwise, it will not be shown.
I can take a photo and it shows in imageviewn but as soon as I leave detailviewn and go to back to detailviewn its disappear. How should the image always be saved?
- (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];
}
- (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];
}
- (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];
}
Check your IBOutlet Connection in xib file and You have to save the image taken in documents directory of your application , unless you cannot view the selected image
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
