I've implemented a PickerController to have a user select an image, but I want the image the user selects to be displayed on the UIImageView I have.
I use the following to go to the camera roll:
- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];
[self presentModalViewController: picker animated: YES];
[self presentModalViewController: picker animated: YES];
}
Which brings up the camera roll in which a user can click on a photo. However, after the click, it returns to the main view, which is obvious... But how can I assign an action to the button, or image the user selects. Something like UIOKButton?
Something like:
if ([UIImagePickerController presentModalViewController:nil image:nil] == UIOKButton ) {
NSArray *images = [UIImagePickerController images];
for(UIImage* pickerImage in [UIImagePickerController images])
{
myUIImage.image setImage pickerImage;
//^in the view
}
I'm not exactly sure how to go about doing this.
All responses are appreciated.
Thanks!
- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];
[self presentModalViewController: picker animated: YES];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// Dismiss the picker
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
// Get the image from the result
UIImage* image = [info valueForKey:#"UIImagePickerControllerOriginalImage"];
myUIImage.image = image;
}
Use the delegate method: – imagePickerController:didFinishPickingMediaWithInfo:.

Can somebody guide me on getting the sender button Tag/Name/ID in below method?
-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
// I Want to get the sender button reference here
}
you can use picker.view.tag to identify the UIImagePickerController type. whenever you called UIImagePicker you can set the tag of its view.
I have used the same for identifying different image picker.
EDIT
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.allowsEditing = YES;
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.view.tag = 5;//set the tag here
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editingInfo
{
NSLog(#"%d",picker.view.tag);
}
you will get the tag value wahtever you will set.
Try this
-(IBAction)ownMethod:(id)sender
{
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.allowsEditing = YES;
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
**imagePickerController.view.tag = [sender tag];//set the tag of button to picker tag **
[self presentViewController:imagePickerController animated:YES completion:nil];
}
I am trying to display a UIImagePicker from a programatically generated UIView that's added as a subview of the original view controller. The image picker comes up and so does the camera but the functionality breaks and nothing navigates properly. How do I properly load an image picker from a UIView and not a UIControlView?
code that breaks:
- (void)captureImage:(id)sender
{
[[[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:#"Close"
destructiveButtonTitle:nil
otherButtonTitles:#"Take photo", #"Camera Roll", nil]
showInView:self];
}
//UIImagePicker specific methods
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex)
{
case 0:
[self takePhoto];
break;
case 1:
[self fromCameraRoll];
break;
}
}
-(void)takePhoto
{
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == YES)
{
// Create image picker controller
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
// Set source to the camera
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
// Delegate is self
imagePicker.delegate = self;
// Show image picker
[self addSubview:imagePicker.view];
}
}
-(void)fromCameraRoll
{
UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self addSubview:imgPicker.view];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Access the uncropped image from info dictionary
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
//do something with the image
//add code to pick images here and store them in the preview
[picker dismissModalViewControllerAnimated:NO];
}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissModalViewControllerAnimated:NO];
}
UIImagePickerController is view controller class, you better present your image picker to your parent view controller by a delegate call or something like with an overlay subview to achieve your goal.
UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
CustomOverlayView *overlayview = [[CustomOverlayView alloc] init];
imgPicker.cameraOverlayView = overlayview;
[self presentModelViewController:imgPicker animated:YES];
add another delegate in your overlay class to dismiss your camera picker controller view
[imgPicker dismissModelViewControllerAnimated:YES];
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;
}
I have a uibutton to trigger an iphone's camera to grab an image, and I have a uiimageView in same view to show captured image, but it not showing anything after capturing.
Any solution?
here's my code:
(IBAction)grabImage:(id)sender{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsImageEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController: picker animated:YES];
[picker release];
}
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage : (UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
cameraImageView.image = image;
[picker dismissModalViewControllerAnimated:YES];
}
I've got a very simple app where the user selects a UIImageView and presses a button to take a photo with the camera. The image is then returned and displayed in the UIImageView.
However, since the UIImageViews are sharing the same delegate, when there's already an image in one of the UIImageViews, and I go to take a photo to be placed in another, the previous UIImageView is replaced with empty content (i.e. no image). I guess this is because they're sharing the same delegate. Is there any way I can essentially copy the image instead of referencing the delegate version of it?
Here's some sample code:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
[picker.parentViewController dismissModalViewControllerAnimated:YES];
if (topView == YES)
{
NSLog(#"topView = %i", topView);
imageView.image = image;
}
else {
NSLog(#"topView = %i", topView);
imageView2.image = image;
}
}
Thanks!
Edit: Here's the code that gets called by the IBAction on the button presses
- (IBAction) pushPick {
topView = YES;
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
[picker release];
}
- (IBAction) pushPick2 {
topView = NO;
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
[picker release];
}
Something like this:
UIImage * newImage = [UIImage imageWithCGImage:[image CGImage]];
use
[image copy];
But remember that you will need to release the object on dealloc
