Is there a way to decrease the memory when using the code below for the UIImagePickerController? The strange thing is that the memory is not coming above 26MB but it still shows the received memory warning. After taking a picture the app crashes. Memory warning only shows when choosing the camera, when choosing the library it's just fine.
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==actionSheet.cancelButtonIndex){
return;
}
UIImagePickerControllerSourceType type = UIImagePickerControllerSourceTypePhotoLibrary;
if([UIImagePickerController isSourceTypeAvailable:type]){
if(buttonIndex==0 && [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
type = UIImagePickerControllerSourceTypeCamera;
}
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.allowsEditing = NO;
picker.delegate = self;
picker.sourceType = type;
[self presentViewController:picker animated:YES completion:nil];
}
}
#pragma mark - Image Picker Controller delegate methods
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
CLImageEditor *editor = [[CLImageEditor alloc] initWithImage:image];
editor.delegate = self;
[picker pushViewController:editor animated:YES];
}

This code is working fine on ios 10 but it crashes on ios 11 when I present picker
if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
{
UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
pickerController.delegate = self;
pickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
pickerController.showsCameraControls = YES;
pickerController.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie]; // kUTTypeMovie is actually an NSString.
pickerController.videoMaximumDuration = 30.0f; // limits video length to 30 seconds.
[self presentViewController:pickerController animated:YES completion:nil];
}
// Picker Delegate
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info
{
self.videoURL = info[UIImagePickerControllerMediaURL];
[picker dismissViewControllerAnimated:YES completion: nil];
NSString *str = [self.videoURL absoluteString];
}
Just wondering if anybody could help me out identifying and creating an iOS option such as this (http://imgur.com/QSfYavr) when a user clicks on a button, it gives the option to use a camera or choose a picture from photo library. I have researched UIIMAGEPICKER however don't think that is what I am after.
I am using latest Xcode + developing for iOS 7 also.
Thanks.
You can use the following code:
// Set these delegates in the header file
<UIImagePickerControllerDelegate, UINavigationControllerDelegate,UIActionSheetDelegate>
// On Button Action
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:#"Select Face for Perform Dance step"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"Camera", #"Select from Library", nil];
actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
[actionSheet showInView:self.view];
// Action sheet delegate
#pragma mark -
#pragma mark UIActionSheetDelegate
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
int i = buttonIndex;
switch(i)
{
case 0:
{
UIImagePickerController * picker = [[[UIImagePickerController alloc] init] autorelease];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:YES completion:^{}];
}
break;
case 1:
{
UIImagePickerController * picker = [[[UIImagePickerController alloc] init] autorelease];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:^{}];
}
default:
// Do Nothing.........
break;
}
}
At last handle camera and select from gallery actions:
#pragma mark -
#pragma - mark Selecting Image from Camera and Library
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Picking Image from Camera/ Library
[picker dismissViewControllerAnimated:YES completion:^{}];
self.selectedImage = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
if (!self.selectedImage)
{
return;
}
// Adjusting Image Orientation
NSData *data = UIImagePNGRepresentation(selectedImage);
UIImage *tmp = [UIImage imageWithData:data];
UIImage *fixed = [UIImage imageWithCGImage:tmp.CGImage
scale:selectedImage.scale
orientation:self.selectedImage.imageOrientation];
self.selectedImage = fixed;
}
This code will work on all iOS SDKs 5.x, 6.x, 7.x.
Enjoy. :)
Its UIActionSheet for iOS7, if you updating your app for iOS7 looks for all iOS versions prior to iOS7, here's one already made, you can check it, https://github.com/ianb821/IBActionSheet
I have an app which has a toolbar at the bottom with one of the options as Upload. On clicking on it, a PopOverController occurs which displays the list of photos to choose from.
After choosing a photo, I want to display a view (inside the PopOverController itself)which contains the photo alongwith the button called as Upload. On choosing my photo, currently my PopOverController is not getting dismissed. I have used the following lines of code :
-(IBAction)photolibrarypressed:(id)sender{
NSLog(#"hi");
UIImagePickerController *picker= [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.delegate = self;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
self.popoverController = popover;
popoverController.delegate = self;
[popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
imageView = [[UIImageView alloc] initWithFrame:[window bounds]];
[window addSubview:imageView];
imageView.hidden = YES;
[window makeKeyAndVisible];
}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
imageView.image = image;
NSLog(#"hellow");
[self dismissModalViewControllerAnimated:YES];
// need to show the upload image button now
upload.hidden = NO;
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[picker dismissModalViewControllerAnimated:YES];
exit(0);
}
Can Someone help me to sort out the issue ??
Instead of calling
[self dismissModalViewControllerAnimated:YES];
call the same cancel method as int eh cancel method to handle dismissing it's modal view
[picker dismissModalViewControllerAnimated:YES]; // Dismisses modalView
I'm able to call the modal view controller for the image picker, pick the image, and crop it, but when I tap 'done' it doesn't do anything, it just hangs with the done button grayed out.
There are no errors, but the function is called.
- (void)viewDidLoad
{
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.allowsImageEditing = YES;
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo {
userImage.image = img;
uploadButton.hidden = NO;
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
NSLog(#"called");
}
- (IBAction)getImage:(id)sender {
[self presentModalViewController:self.imgPicker animated:YES];
}
Replace
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
with:
[self dismissModalViewControllerAnimated:YES];
I am using UIimagepickercontroller to browse or take a photo and display it on a subview.
-(IBAction) getPhoto:(id) sender {
secondView1 = [[secondView alloc]
initWithNibName:#"secondView"
bundle:nil];
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if((UIButton *) sender == choosePhotoBtn) {
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
} else {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
[self presentModalViewController:picker animated:YES];
[self.view addSubview:secondView1.view];
}
This works fine for SourceTypeSavedPhotoAlbum, but if I use camera, the secondview1.view does not show. Instead it only shows the original view.
This is my delegate method:
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
secondView1.imageView.image = [info
objectForKey:#"UIImagePickerControllerOriginalImage"];
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
[picker release];
}
Thank you for any help!
I finally found out that I should do:
secondView1 = [[secondView alloc]
initWithNibName:#"secondView"
bundle:nil];
self.view addSubview:secondView1.view];
in the delegate function.
(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
...
}
Otherwise, the addsubview could be called before the image picker finishes picking an image. Now understand better about how the code flows and the delegate functions.
